- viens
- capillaries
Identify three characteristics of viens?
- have valves to prevent backflow
- carries deoxygenated blood back to the heart
- carries blood at low pressure
Identify three characteristics of arteries?
- Carries oxygentaged blood away the heart
- carries blood at high pressure
- have thick walls
Identify three characteristics of capilares?
- small
- allow carbon dioxide and waste products to pass through

Aorta, Vena cava, pulmonary vein, pulmonary artery
What structure seperates the left side and the right side of the heart?
The spetum
What is the formula for cardiac output?

What is meant by cardiac output?
The amount of blood pumped out the heart in one minute.
What is meant by stroke volume?
Amount of blood pumped out of the heart by each ventricle during one contraction
Define heart rate?
