Blood Circulation in the Heart and Other Mammals
In the circulatory system of humans and other mammals, blood circulates through two main circuits: the systemic circulation and the pulmonary circulation. The systemic circulation carries oxygenated blood from the heart to the body's tissues, while the pulmonary circulation carries deoxygenated blood from the heart to the lungs for oxygenation.
Arterial and Venous Blood: - Arterial blood refers to oxygenated blood that is pumped out of the heart and into the systemic circulation. - Venous blood refers to deoxygenated blood that returns to the heart from the body's tissues.
Circulation in the Heart: - The heart has four chambers: two atria and two ventricles. - Oxygenated blood from the lungs enters the left atrium and is then pumped into the left ventricle. - The left ventricle contracts, pumping the oxygenated blood into the systemic circulation through the aorta. - Deoxygenated blood from the body's tissues enters the right atrium and is then pumped into the right ventricle. - The right ventricle contracts, pumping the deoxygenated blood into the pulmonary circulation through the pulmonary artery, where it is oxygenated in the lungs.
Amount of Oxygen in Arterial and Venous Blood:
