Diagram of the heart labelled - game quiz

Play and learn with a diagrm of the heart labelled. It is an interactive game with a quiz.

 

This page features a labelled diagram of the heart. Children are required to learn the anatomy of the heart through an online game which requires dragging and dropping labels of the different parts. After labelling all the parts, submit your response to find out if you got it right. This diagram is an interactive online activity for children to learn how to label a simple diagram of the heart.
The main function of the heart is to pump blood throughout the body via the circulatory system. By so doing, this organ plays a vital role in supplying oxygen and nutrients to other parts of the body while eliminating CO2 and other bodily wastes.
The human heart is estimated to weight approximately 280 to 340 grams in men and between 230 to 340 grams in women. Notice that men have slightly larger hearts than women. In fact the heart has four main chambers – two upper chambers and two lower chambers. The heart is also divided into a right side and a left side.
The heart functions like a machine, constantly beating at 60 to 80 times per minute, pumping about 5.7 litters of blood throughout the body. Although the heart is located in the center of the chest, it is slightly more inclined to the left.
There are several interesting facts about the heart and the best way to start learning these facts is to know the anatomy of the heart. This activity has been designed to play the role of an online worksheet where students can practice for free an unlimited amount of times. This online worksheet on the excretory system can be used to teach children biology in 2nd, 3rd, 4th, 5th, 6th, and 7th grade.

Parts of the heart and their functions

The heart is a muscular organ that pumps blood throughout the body. It has four chambers: the left and right atria, and the left and right ventricles.

The left atrium receives oxygenated blood from the lungs and pumps it into the left ventricle, which then pumps it out to the rest of the body. The right atrium receives deoxygenated blood from the body and pumps it into the right ventricle, which pumps it to the lungs to be oxygenated.

The walls of the heart are made up of three layers of tissue: the endocardium, the myocardium, and the epicardium. The endocardium is the innermost layer and lines the chambers of the heart. The myocardium is the middle layer and is made up of cardiac muscle tissue, which contracts to pump blood. The epicardium is the outermost layer and covers the surface of the heart.

The heart also has four valves that help to ensure that blood flows in the correct direction through the heart: the tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve.

The tricuspid valve is located between the right atrium and the right ventricle, and the pulmonary valve is located between the right ventricle and the pulmonary artery, which carries deoxygenated blood to the lungs. The mitral valve is located between the left atrium and the left ventricle, and the aortic valve is located between the left ventricle and the aorta, which carries oxygenated blood to the rest of the body.

A Human Heart Diagram Explained

The human heart is a four-chambered double pump at the center of our circulatory system. It is located between the two lungs, slightly to the left of the center. It sits on a muscular wall known as the diaphragm, which separates the chest and abdominal cavities. When the heart is enlarged, blood leaks back into the atria. The problem is often caused by damage or narrowing of the valves.

The right side of the heart pumps blood to the lungs while the left side pumps blood to the systemic circulation. The two sides of the heart contract at the same time, and the blood flows from the right atrium to the right ventricle. The left atrium pumps blood to the rest of the body and the lungs receive oxygen. The heart beats in unison, or in alternating rhythms. The heart's chambers are separated by a series of valves known as atrioventricular valves.

The heart is composed of four chambers - the left atrium, the right atrium, and the right ventricle. The atriums are smaller than the ventricles, and the right ventricle is larger than the left. The atria and the ventricles are connected by arteries. The atria contain oxygen-rich blood. The other chambers, known as the ventricular chambers, carry the waste products.

The left atrium pumps blood to the aorta through the mitral and aortic valves. The left atrium is the pumping chamber and the left ventricle provides the heart muscle with oxygen-rich blood.

The lower section of the heart is called the ventricles, and is responsible for pumping oxygen-rich blood to the smallest cells. These chambers are separated by semilunar valves, which are the pulmonary and aortic valves. The heart wall is made of three layers. The two outer layers are the myocardium, which is the thickest. The pericardium protects the heart from injuries.

The right heart collects deoxygenated blood from two large veins: the superior vena cava and the inferior vena cava. The blood is pumped to the lungs for oxygen, while the left ventricle sends the deoxygenated blood to the systemic circulation. When the heart is in proper functioning mode, the left side is the most important. 

The right atrium and the left ventricle are separated by a pericardial sac, which is lined with parietal and visceral layers of serous membrane. The atrium is the upper chamber, while the ventricle is the lower chamber.
