How To Draw A Human Heart Step By Step Human Heart Drawing Easy

The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.

The heart has four chambers:

  • The right atrium receives blood from the veins and pumps it to the right ventricle.
  • The right ventricle receives blood from the right atrium and pumps it to the lungs, where it is loaded with oxygen.
  • The left atrium receives oxygenated blood from the lungs and pumps it to the left ventricle.
  • The left ventricle pumps oxygen-rich blood to the rest of the body. The left ventricle√Ęs vigorous contractions create our blood pressure.

The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. A web of nerve tissue also runs through the heart, conducting the complex signals that govern contraction and relaxation. Surrounding the heart is a sac called the pericardium.

Your Human Heart Drawing Is Complete

Normal heart anatomy and physiology

Normal heart anatomy and physiology need the atria and ventricles to work sequentially, contracting and relaxing to pump blood out of the heart and then to let the chambers refill. When blood leaves each chamber of the heart, it passes through a valve that is designed to prevent backflow of blood. There are four heart valves within the heart:

  • Mitral valve between the left atrium and left ventricle
  • Tricuspid valve between the right atrium and right ventricle
  • Aortic valve between the left ventricle and aorta
  • Pulmonic valve between the right ventricle and pulmonary artery

By Step Instructions For Drawing A Human Heart

1. Begin by sketching a rounded, lumpy, irregular figure. It should look a bit like the shape of Africa. This outlines the lower chamber of the heart, which includes both the left and right ventricles.

2. Next you will draw the aortic arch. Extend two curved lines upwards from the irregular shape. The lines should follow a roughly parallel path, with the lower line being slightly shorter. Connect the lines at the end using a short curved line.

3. Next, you will draw the pulmonary trunk, as well as the left and right pulmonary arteries. Draw a short wavy line within the original figure, then it extend it up to meet the aortic arch. On the other side, extend a long curved line, ending at a small oval. Connect this oval to the aortic arch using a curved line that crosses over the end of the arch.

4. Erase guide lines from the heart.

8. Draw the left atrium and pulmonary veins. Enclose an irregular shape for the atrium. Extend a curved line upwards from this, and then draw the veins using pairs of parallel, curved lines. Connect them at the ends using curved lines or ovals.

9. Detail and texture the heart using short lines. Allow some to branch, indicating veins.

10. In scientific drawings, portions of the heart carrying oxygenated blood are typically depicted in red, while those carrying blood to the lungs for re-oxygenation are shaded purple or blue.

Coronary veins -take oxygen-poor blood that has already been “used” by muscles of the heart and returns it to the right atrium.

Circumflex artery – supplies blood to the left atrium and the side and back of the left ventricle.

Left coronary artery – divides into two branches .

Left anterior descending artery – supplies blood to the front and bottom of the left ventricle and the front of the septum.

Pulmonary veins -bring oxygen-rich blood back to the heart from the lungs.

Right coronary artery – supplies blood to the right atrium, right ventricle, bottom portion of the left ventricle and back of the septum.

How Your Body Controls Heart Rate And Blood Pressure

How fast and hard your heart beats is controlled by signals from your bodys nervous system, as well as by hormones from your endocrine system. These signals and hormones allow you to adapt to changes in the amount of oxygen and nutrients your body needs. For example, when you exercise, your muscles need more oxygen, so your heart beats faster. When you sleep, your heart beats slower.

Next Draw Some Veins And More Of The Outline

The main job of the heart is to pump blood throughout the body, and this is helped by veins and other chambers, so we shall draw some veins in this part of your human heart drawing.

To draw these veins, simply use lots of curvy, twisty lines on the interior of the heart to make the veins snaking throughout the heart. Then its on to step 3 for more of the drawing.

Anatomy Of Your Heart

Your heart is in the center of your chest, near your lungs. It has four hollow heart chambers surrounded by muscle and other heart tissue. The chambers are separated by heart valves, which make sure that the blood keeps flowing in the right direction. Read more about heart valves in Blood Flow.

Anatomy of the interior of the heart. This image shows the four chambers of the heart and the direction that blood flows through the heart. Oxygen-poor blood, shown in blue-purple, flows into the heart and is pumped out to the lungs. Then oxygen-rich blood, shown in red, is pumped out to the rest of the body, with the help of the heart valves.

The human form is an early assignment in most drawing classes. According to BBC, “the human figure offers all the complexities an artist needs to learn in order to be able to conquer any drawing subject.”

Reporter Will Gompertz continues, “Every time a model makes a move, there’s something to learn and work on. Shadows and skin texture, the way the limbs move, extend. Every pose or position, reveals a whole new composition, and another focus for a drawing. A great range of movement is possible, right in front of you, which combined with the anatomical and structural complexity of the body, make particular demands on us when we draw.”

The above refers to sketching from a live model. But you, too, can begin your drawing journey with a sketch of the human form, even if a model is not available. This body outline drawing guide is designed to help you do just that. It will help you learn about human proportions of the head, torso, and limbs. Later, you can fill in additional details and bring your drawing to life.

Blood Supply To The Myocardium

The myocardium of the heart wall is a working muscle that needs a continuous supply of oxygen and nutrients to function efficiently. For this reason, cardiac muscle has an extensive network of blood vessels to bring oxygen to the contracting cells and to remove waste products.

The right and left coronary arteries, branches of the ascending aorta, supply blood to the walls of the myocardium. After blood passes through the capillaries in the myocardium, it enters a system of cardiac veins. Most of the cardiac veins drain into the coronary sinus, which opens into the right atrium.

How Can You Prevent Heart Attacks And Strokes

According to the American Heart Association, no matter what age you are, your heart can benefit from a healthy diet and adequate physical activity. Tthere are numerous specific suggestions about how you can decrease your risk for heart disease. For example:

How Does Blood Flow Through The Heart To The Lungs

  • Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation.
  • From your pulmonic valve, blood travels to the pulmonary artery to tiny capillary vessels in the lungs.
  • Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood.
  • At the same time, carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs.
  • Carbon dioxide leaves the body when you exhale.
  • Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.

How Does Heart Work

How to draw HUMAN HEART in easy way
  • The right and left sides are also separated into two top chambers called the atria , which collect blood and then pump it into the two lower chambers called ventricles, which channel blood into the lungs and the abdomen
  • The coronary arteries are on the top of the heart
  • The coronary arteries and nerves are a mini-circulatory network of the heart itself
  • Two main coronary arteries branch from the aorta near the point where the aorta connects with the left ventricle: A left coronary artery carries blood to the right atrium and right ventricle.

2.1 How Does The Heart Valves Work

Four valves control the blood flow through the heart:

  • The tricuspid valve controls the flow of blood between the right ventricle and right atrium
  • The pulmonary valve regulates blood supply from the right ventricle into the pulmonary arteries that hold the blood to suck up oxygen to the lungs
  • The mitral valve helps the lungs transfer oxygen-rich blood from the left atrium into the left ventricle
  • The aortic valve opens the door for blood rich in oxygen to flow from the left ventricle into the aorta, the main artery in the body.

The heart valves operate the same way as one-way valves, which helps to block the flow of blood in the wrong direction.

Structure Of The Heart

The human heart is a four-chambered muscular organ, shaped and sized roughly like a man’s closed fist with two-thirds of the mass to the left of midline.

The heart is enclosed in a pericardial sac that is lined with the parietal layers of a serous membrane. The visceral layer of the serous membrane forms the epicardium.

Finish Off The Details And Touches Of Your Human Heart Drawing

This fifth step of our guide on how to drawa human heart will be all about finishing off the final details of your picture.

The details that we will be adding will be going on the top left-hand side of the heart. You can use some curved lines for the aortas poking off that side of the top of the heart.

With those final details, you have finished all of the steps in this guide! You dont have to stop there, as there are lots more details that you could add to finish it off.

One idea you could go with would be to look up a diagram of a human heart and label the different parts of the heart.

You could also draw some more organs to go with it or incorporate it into a cool design. These are just a few ideas that you could go with, but what else can you think of to finish off this drawing?

Then, draw the arteries and veins that extend from the heart. You can make your heart as detailed or colorful as you like!

What Are Heart Sounds

How to draw a Heart | parts of the inner body | Easy step by step drawing for kids

The rhythmic noises accompanying the heartbeat are called heart sounds. The two distinct sounds are heard, a low, slightly prolonged lub occurring at the beginning of ventricular contraction or systole and a sharper, higher-pitched dup , caused by the closure of aortic and pulmonary valves at the end of systole.

heart, organ that serves as a pump to circulate the blood. It may be a straight tube, as in spiders and annelid worms, or a somewhat more elaborate structure with one or more receiving chambers and a main pumping chamber , as in mollusks. In fishes the heart is a folded tube, with three or four enlarged areas that correspond to the chambers in the mammalian heart. In animals with lungsamphibians, reptiles, birds, and mammalsthe heart shows various stages of evolution from a single to a double pump that circulates blood to the lungs and to the body as a whole.

In humans and other mammals and in birds, the heart is a four-chambered double pump that is the centre of the circulatory system. In humans it is situated between the two lungs and slightly to the left of centre, behind the breastbone it rests on the diaphragm, the muscular partition between the chest and the abdominal cavity.

Now Draw Some More Of The Heart

Your human heart drawing is looking great already! In this step, we shall be adding some more parts onto the top of the heart.

First, use two curved lines at the top of the heart for one of the larger chambers of the heart. It will also have some thin and subtle lines on it for some extra detail.

Then there will be another shape on the top right side of the heart that has more aortas sticking out of it.

There will also be some minor details on it that you can draw with some small, curved lines. Then its on to some final details in the next step before you color in your heart!

How To Draw A Picture Of A Heart

The human heart is an important part of the circulatory system and its beat is what keeps blood flowing through your body. In fact, National Geographic reports that the human heart pumps approximately two gallons of blood to every area of your body. If the heart is the subject matter of your latest class or science project, you may be required to draw a picture of it. While the heart is indeed an intricate organ, a simple illustration can be drawn to depict its main features.

Begin your heart picture by drawing the main part of the heart with the pulmonary artery erupting from the upper area. It is the pulmonary artery that is responsible for carrying blood from the heart to the lungs.

Add the left ventricle and atrium to your heart picture, followed by the right atrium and ventricle. It is the job of the right side of the heart to collect de-oxygenated blood and pump it into the lungs. The lungs then oxygenate the blood, and it is then pumped back into the heart through the left side.

Draw the vena cava at the upper left of your heart. The vena cava is a very large vein that is responsible for carrying the blood from the upper areas of your body back into the heart.

Add the aorta to the upper part of your heart picture. The aorta is not only one of the most important arteries in the heart, it is also the biggest. It is the job of the aorta to supply oxygenated blood to all of your arteries.
