Your heart is a hard working muscle. If it takes you one minute to read this paragraph, your heart will have accomplished around 72 beats.
Today, it will beat abouttimes. During your lifetime, your heart will beat over two billion times. Mammals and birds have four chambered hearts like ours, while the heart of a spider is a simple tube. Interestingly, scientists have discovered that resting pulse correlates to average lifespan. For example, small animals like mice and hummingbirds have rapid heart rates, and may live for only a few months.
How to clean rose gold plated watch hearts of whales, on the other hand, may beat only a few times per minute. They outlive us by hundreds of years. Scroll down for a downloadable PDF of this tutorial. To take care of your heart, researchers recommend getting plenty of exercise, adequate sleep, and a healthy diet.

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. Next you will draw the what format do ipods use for video 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.
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.
Next, draw the right atrium and the superior vena cava. For the atrium, enclose an irregular form at the junction of the ventricle and the aortic arch. Above this, draw a narrow vertical oval along the arch, and connect this to the atrium using a curved line. This is the superior vena cava. Using a series of curved lines, draw the left coronary artery crossing the ventricle. This artery should resemble the branching of a tree, with the lines getting progressively shorter and ending in points.
Erase guide lines as necessary. Draw major arteries extending from the aortic arch. Ror each, extend sets of parallel curved lines, and connect them at the top. Cause one to branch using a "V" shaped line. 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. Detail and texture the heart using short lines. Allow some to branch, indicating veins.
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.

How to draw Internal structure of mammalian Heart The heart is mesodermal in origin. It is a thick walled, muscular and pulsating organ, situated in the mediastinum, and with its apex slightly turned to the left, it is of the size of a clinched fist.
This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. This article has been viewed , times. Learn more Are you fascinated with anatomy, or looking to take your drawing skills to the next level? Drawing realistic anatomy can be a challenge. To draw the internal structure of a human heart, follow the steps below.
To draw the internal structure of the heart, start by sketching the 2 pulmonary veins to the lower left of the aorta and the bottom of the inferior vena cava slightly to the right of that. Then, fill in the base of the heart with the right and left ventricles and the right and left atriums. Once you have the basic outline of the heart sketched out, use an existing diagram to help you fill in the additional veins and muscles, like the mitral and aortic valves.

Draw the top vein slightly smaller than the bottom vein. Below the pulmonary veins, and slightly to the right, begin sketching the bottom of the inferior vena cava. Begin sketching the base of the heart, including the right and left ventricles, and the right and left atriums. The pulmonary veins should be adjacent to the right atrium, and the inferior vena cava should be adjacent to the right atrium and right ventricle. Change diagrams if needed.
If the diagram that you are using is helping you to sketch the heart, you should continue to use the same diagram. If you are confused about where parts of the heart are, find a new diagram. Part 2 of Draw the other side of the pulmonary veins, and add circles at the end. Begin drawing the pulmonary artery. Bottom ends at the top of the right ventricle. The left and right sides should be slightly above the atriums and pulmonary veins. The pulmonary artery is shaped like an uppercase 't'.
It extends to the top of the right ventricle. Draw a circle at the end of it at the bottom. To draw the aorta, begin by drawing the loop over and around the pulmonary artery, ending at the top of the left ventricle. To draw the back of the aorta, draw a single line connecting from the right side of the pulmonary artery to the top of the left atrium. To finish drawing the aorta, draw three nubs at the top of the loop. After you draw these, erase the lines connecting from one side of the bottom of the nub to the other.
Add tilted circles to the top of all of the nubs. Draw a circle at the bottom of the aorta, adjacent to the left ventricle. To draw the superior vena cava, draw a nub extending from the top of the right atrium, overlapping the left side of the pulmonary artery, to slightly above the left side of the pulmonary artery.
At the bottom of the superior vena cava, adjacent to the right atrium, draw a circle. Draw four circles in the left atrium, and one circle in the right atrium, slightly below the superior vena cava. Draw the mitral valves between both atriums, and aortic valves in both the pulmonary artery and the aorta.
Part 3 of The human heart is roughly the size of a large fist. The human heart weighs about 10 to 12 ounces in men, and about 8 to 10 ounces in women. Not Helpful 2 Helpful The muscles are drawn as thick lines in the cross-section and the outside is completely made out of muscles. There is no need to specifically draw muscles, as they are already incorporated in the diagram. Not Helpful 4 Helpful An octopus has three hearts. One heart is to circulate the blood around the body, while the other two are for pumping the blood to the gills.
Not Helpful 7 Helpful Because it collects deoxygenated blood from entire body and send it to lungs to get the blood oxygenated. After this, oxygen-rich blood is pumped by the heart to the rest of the body.
Main function of valve is to prevent back flow of blood. This is because blood pressure in veins is very low compared to arteries. There is no need of valves in the arteries because the blood pressure usually varies between mm Hg. Not Helpful 11 Helpful Can one atrium be bigger than another? And can a ventricle be bigger than its partner? Yes, this is the case with every human on Earth! The right atrium is larger than the left atrium and the right ventricle is larger than the left ventricle.
This is because the left side of the heart has thicker walls than the right side. Use a sharp pencil, keep an eraser handy, and don't be scared of mistakes. Not Helpful 15 Helpful Include your email address to get a message when this question is answered. Helpful 1 Not Helpful 0.
