GROSS ANATOMY

Detailed explanation-1: -The human circulatory system has three key components: blood vessels, blood and the heart. It is called a double circulatory system because blood passes through the heart twice per circuit. The right pump sends deoxygenated blood to the lungs where it becomes oxygenated and returns back to the heart.

Detailed explanation-2: -The heart works as a double circulatory system. This means two pumps that work at the same time to pump blood in two different directions. The right-hand side of the heart collects deoxygenated blood from the body and pumps it to the lungs (to collect more oxygen).

Detailed explanation-3: -A mechanism in which blood circulates twice through the heart in one complete cycle is known as double circulation. Systemic circulation and pulmonary circulation are two pathways in which the blood flows in double circulation. Double circulation is present in birds and mammals.

Detailed explanation-4: -The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Detailed explanation-5: -The human circulatory system consists of blood, heart, blood vessels, and lymph. The human circulatory system circulates blood through two loops (double circulation) – One for oxygenated blood, another for deoxygenated blood. The human heart consists of four chambers – two ventricles and two auricles.
