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.
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.
