The main parts of the system are the heart, arteries, capillaries and veins. The circulatory system does a very important job in your body. It carries oxygen and essential nutrients to all cells around the body in arteries and carries the waste products and carbon dioxide in veins.

Two systems that work very closely together are our cardiovascular and respiratory systems. The cardiovascular system includes your heart and blood vessels, which function to remove deoxygenated blood from and return oxygenated blood throughout your body.

The human circulatory system is a double circulatory system. It has two separate circuits and blood passes through the heart twice: the pulmonary circuit is between the heart and lungs. the systemic circuit is between the heart and the other organs.

The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).

The essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood.

The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.

What are the three main parts of the circulatory system? The three main parts of the circulatory system are the blood, the blood vessels that the blood flows through, and the heart that pumps the blood around. What are the four parts of blood?

The main function of blood vessels is to carry blood through the body. The blood carries oxygen, nutrients, and wastes that need to circulate the body. The three kinds of blood vessels are: arteries, veins, and capillaries. The arteries carry blood away from the heart and transport it to the rest of the body.

What does your heart do? The purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries. Oxygen-rich blood is pumped out of the left side of your heart (shown on the right in the diagram) into the arteries to these tissues and organs.

The Circulatory System The circulatory (or cardiovascular) system is a closed network of organs and vessels that moves blood around the body (Figure 1). The primary purposes of the circulatory system are to deliver nutrients, immune factors, and oxygen to tissues and to carry away waste products for elimination.
