CIRCULATORY SYSTEM

• CIRCULATORY SYSTEM - it functions with the other body systems to deliver different materials in the body
• HEART - pumps the blood throughout the body
• BLOOD VESSELS - carries the blood throughout the body
• VEINS - carries blood towards the heart
• ARTERIES - carries the blood away from the heart
• CAPILLARIES - smallest blood vessel in the body
• BLOOD - carries the materials towards the body
• CIRCULATORY SYSTEM - also called cardiovascular system
• AORTA - largest artery that leaves the left ventricle of the heart
• The heart has four chambers with two specific tasks to do.
• the two atria are the receiving chambers of the heart
• the two ventricles are the pumping chambers.
• VALVE - between the atrium and ventricle to prevent blood from flowing backwards.
• SUPERIOR VENA CAVA - where deoxygenated blood enters
• PULMONARY ARTERY - deoxygenated blood exits here to the lungs to get oxygen
• PULMONARY VEIN - oxygenated blood from the lungs enters this vein to gets to the heart
• RIGHT VENTRICLE - pumps deoxygenated blood to pass through the pulmonary artery
• RIGHT ATRIUM - received deoxygenated blood from the superior vena cava
• LEFT VENTRICLE - forces oxygenated blood through the aortic valve to be distributed to the entire body
• LEFT ATRIUM - receives blood full of oxygen from the lungs and then empties the blood into the left ventricle
• PULMONARY CIRCULATION - movement of blood from the heart, to the lungs, and back to the heart
• CORONARY CIRCULATION - movement of the blood through the tissues of the heart.
• SYSTEMATIC CIRCULATION - movement of blood, from the heart, to the rest of the body (excluding the lungs)
