Cardiovascular System
The cardiovascular system consists of the heart, blood vessels, and the 5 liters of blood that the blood vessels transport. Responsible
for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s
hardest-working organ — the heart, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 liters of blood
throughout the body every minute. The cardiovascular system transports blood to almost all of the body’s tissues. The blood delivers essential nutrients and oxygen and removes wastes and carbon dioxide to be processed or removed from the body.
BLOOD VESSELS
VEINS: Veins are the blood vessels that carry deoxygenated blood towards the heart.
ARTERIES: Arteries are the blood vessels that carry oxygenated blood towards the muscles.
CAPILLARIES: Capillaries are the smallest blood vessels in the body, and are the blood
vessels responsible for actually delivering oxygen and other nutrients to the
tissues. These are 1 cell thick tubes.
HOW IT WORKS?
BLOOD
Blood is made up of 4 parts. Red blood cells, white blood cells, platletes and plasma:
Red Blood Cells: Red blood cells are the movers of oxygen to the muscles. it also takes the deoxygenated blood or Carbon Dioxide away from your muscles and back to the heart where it can be oxygenated again.
White Blood Cells: The White Blood Cells are the warriors of th body. they fight off any infections in the body.
Plateletes: Plateletes are cells in your blood that helps to stop bleeding from a cut.
Plasma: Plasma is a yellowish liquid that transfers nutrients,hormones and proteins throughout the body.

HOW IT WORKS?
- Pulmonary circulation transports deoxygenated blood from the right side of
the heart to the lungs, where
the blood picks up oxygen and returns to the left side of the heart. The pumping
chambers of the heart that support the pulmonary circulation loop are the right
atrium and right ventricle. Systemic circulation carries highly oxygenated blood from the left side of
the heart to all of the tissues of the body (with the exception of the heart and
lungs). Systemic circulation removes wastes from body tissues and returns
deoxygenated blood to the right side of the heart. The left atrium and left
ventricle of the heart are the pumping chambers for the systemic circulation
loop.
