The cardio-vascular system of humans is designed to move blood cells, oxygen, nutrients, and carbon dioxide to various parts of the body in the form of your blood. The heart keeps the blood moving by pumping oxidized blood through the body and blood devoid of oxygen to the lungs. The heart is divided into 4 sections. The upper half is the atrium, and the lower half is the ventricle. There is a left and right side for each. The right atrium recieves deoxygenated blood (little/no oxygen) and the right ventricle pumps it to the lungs. The left atrium recieves oxygenated blood and the left ventricle pumps it through the body.
The blood passes through vessels in order to reach all of your body. The main types of blood vessels are:
Arteries- The largest blood vessels, they carry blood away from the heart to bring nutrients to other parts of your body. The aorta is the largest artery.
Capillaries- The smallest blood vessels, they interact with your tissues and deposit the nutrients in your blood
Veins- These blood vessels carry blood back to the heart so it may recieve more nutrients and be pumped through again.
