Question

explain the structure of the heart ​

Answer 1

Answer:

• The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.

• The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood.

• The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.

• The lungs re-oxygenate the blood and send it to the left atrium.

• Blood moves from the left atrium to the left ventricle via the bicuspid valve; blood is pumped out of the left ventricle to the aorta, which sends blood to the organs and muscles of the body.

• The heart is composed of three layers: the epicardium (outer layer), the myocardium (middle layer), and the endocardium (inner layer).

• Key Terms
• aorta: the largest artery in the human body which carries the blood from the heart to all parts of the body except the lungs. inferior vena cava: large vein that carries deoxygenated blood from the lower half of the body to the right atrium of the heart superior vena cava: large vein that carries deoxygenated blood from the upper half of the body to the right atrium of the heart
