CARDIOVASCULAR SYSTEM DUDE(=

The cardiovascular system, the most important of the human body systems, consists of organs that are responsible for carrying out many of the important cardiovascular system functions. The system consists of organs like the heart, and the blood vessels that are spread throughout the body. The cardiovascular system is a complex system and understanding its functions will help understand the overall human physiology better.

The cardiovascular system transports oxygen from the lungs to the various cells of the body. The primary function of the cardiovascular system is to transport nutrients from the intestines to the lungs and other parts of the body, and carbon dioxide from the cells to the lungs.

Blood Vessels: There are three different types of blood vessels in the human body, the arteries, the capillaries and the veins. The arteries are of three types, the pulmonary artery, the aorta and the coronary arteries. They perform the function of carrying oxygenated blood from the heart to the other parts of the body, but the pulmonary artery carried deoxygenated blood from the heart to the lungs. The capillaries carry oxygen and nutrients to the tissues and cells of the body and the veins carry deoxygenated blood from the various organs of the body to the heart

if heart doesn't receive any blood eventually we will die in an instant.

The blood needs to flow throughout the heart in order to delivered it to the different parts of the body
