Answer 2

Answer:

The circulatory system

The circulatory system is a network consisting of blood, blood vessels, and the heart. This network supplies tissues in the body with oxygen and other nutrients, transports hormones, and removes unnecessary waste products.

The heart

The heart is made of specialized cardiac muscle tissue that allows it to act as a pump within the circulatory system.

The human heart is divided into four chambers. There are one atrium and one ventricle on each side of the heart. The atria receive blood and the ventricles pump blood.

The human circulatory system consists of several circuits:

The pulmonary circuit provides blood flow between the heart and lungs.

The systemic circuit allows blood to flow to and from the rest of the body.

The coronary circuit strictly provides blood to the heart 

Blood and blood vessels

Blood from the heart is pumped throughout the body using blood vessels. Arteries carry blood away from the heart and into capillaries, providing oxygen (and other nutrients) to tissue and cells. Once oxygen is removed, the blood travels back to the lungs, where it is reoxygenated and returned by veins to the heart.
