- Circulation
- The Heart
- Made of cardiac muscle
- Humans have a double circulatory system to separate oxygenated and deoxygenated blood
- Left - deoxygenated Right - Oxygenated
- LORD
- Vein have valves to stop backflow of blood
- Blood passes through TWICE during a full circuit of the body
- Cardiac Cyle
- Both left and right atriums contract at the same time
- Blood goes from the atria to the ventricles (once they are opened)
- When the ventricles are full, they contract, preventing backflow
- Once the pressure is high enough, the blood is forced into the aorta or pulmonary arteries
- The cycle repeats
- Once the pressure is high enough, the blood is forced into the aorta or pulmonary arteries
- When the ventricles are full, they contract, preventing backflow
- Composition of the Blood
- Haemoglobin
- Red Blood Cells (45% vol)
- Plasma (Yellow and 55% vol)
