The cardiovascular system is the bodies system that is in charge of regulating blood throughout the body. The main job of the cardiovascular systems are transportation of blood which allows the body to receive oxygen, nutrients, and hormones while disposing of wastes. The second job of the cardiovascular system is protection via the white blood cells. White blood cells clean up cellular debris and fight pathogens that have entered the body. The cardio vascular system will also offer protection through the blood carrying antibodies of immunity for previous infections in the body. The final function of the cardiovascular system is regulation. Blood vessels control the homeostasis of the body, an example of this is blood vessels control the amount

Many people will refer to the blood vessels as the body’s highways. This is because the blood vessels allow blood to quickly travel to all parts of the body and back again quickly. There are three major types of blood vessels in the human body. The first are the arteries which face high blood pressure levels due to the fact that they take blood away from the heart, Because of this they are thicker and more elastic then the other blood vessels. Branching off of the arteries are arterioles which carries blood to the second type of blood vessels the capillaries. These are the smallest and thinnest of the three types of blood vessels but also the most common in the body. They can be found running through almost every tissue in the body. Capillaries carry blood very close to the cells of the tissues of the body in order to exchange gases, nutrients, and waste products. The final type of blood vessels are the veins. Veins are seen as the counter part of the arteries ad their job is to pump blood back to the heart from the outer parts of the body. Veins rely on gravity, inertia, and the force of skeletal muscle contractions to help push blood back to the heart because of the fact that once the blood reaches them the blood pressure is so
