COMPONENTS OF THE BLOOD ​

The human circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other substances to and from cells. The heart pumps blood around the body. The blood vessels carry blood to all parts of the body. Blood is a fluid mixture that carries substances like nutrients, oxygen through the body. The circulatory system also removes unwanted substances from the body.

​​Blood cells

The left-hand side pumps oxygenated blood around the body. Each side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the blood collects when it enters the heart. The ventricles pump the blood out of the heart to the lungs or around the body.

Teaching of digestive system

​Receives blood from the lungs

​​Right Atrium

​Receives blood from the lest of the body

Left atrium​

The heart consists of four chambers in which blood flows. Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.
