In the Circulatory System, we have the Heart, Arteries, Veins, and Capillaries. The heart is the organ that pumps blood all throughout the body through networks of blood vessels. The arteries are the ones that take away blood from the heart, while the veins are the ones responsible for carrying blood towards the heart. Lastly, the capillaries are the tiny blood vessels that function between the circulatory system and organs/tissues in the exchange of nutrients, oxygen, and wastes.

Furthermore, the human body consists of two blood circulatory systems. These are Systemic and Pulmonary circulation. Systemic Circulation is the process wherein in order to get oxygen and other significant substances needed, this provides blood in the tissues, organs, and cells. On the other hand, Pulmonary Circulation happens when we breathe the fresh oxygen, which then enters the blood, and from the blood carbon dioxide is also released.

Below is an illustration of Body Tissues in the Circulatory System. It shows the Vena Cava and two angles of Arteries.
