Document Summary
The cardiovascular system: includes the heart, lungs and vessels. Arteries pump oxygenated blood away from the heart (thick elastic walls that enable them volume of blood being pumped through them) After leaving the heart, the aorta branches into smaller capillaries (smallest possibl. Capillaries deliver oxygen rich blood to the tissues and pick up oxygen poor blood. F empties into small veins and then into larger veins to repeat the blood cycle in the. Veins pump deoxygenated blood to the heart (thin walls) A series of valves keep the blood flowing in the correct direction to prevent deoxygenate oxygenated blood going to the heart. Blood needs oxygen, therefore it travels out of the pulmonary artery to the aorta in the lu blood is oxygenated it travels back to the heart via the left atrium. When getting a blood test, blood is taken from a vein rather than an artery because an ar a vein burst.
