What are the 4 chambers of the hear

Answer: 2 top (atrias): Right and left atrium 2 bottom (ventricles): Right and left ventricles

Unit 1: Transport in animals
- 2 types: Open and Closed circulatory system
OPEN:
- Small Organisms
- No blood vessel, have hemocoel
- Blood pump at low pressure
CLOSED:
- Large organisms
- Blood pump rapidly
- blood remain enclosed circulated
- transfer fluid to body
CIRCULATORY SYSTEM:
- Blood: carries nutrients to body
- Blood vessels: Helps transport the blood. To the rest of the body
- Valve: pump blood and allow blood to enter
DEOXYGENATED AND OXYGENATED:
- Deoxygenated blood: from heart to lungs
- Oxygenated blood: from lungs to body
COMPONENTS:
- 4 chambers:
- 2 top (atrias): Right and left atrium
- 2 bottom (ventricles): Right and left ventricles
- Valves:
- Right side of heart: Tricuspid valve, pulmonary valve
- Left side of heart: Mitral valve, Aortic valve, Semilunaris
FUNCTIONS:
- Artery: Blood from heart
- Veins: Blood to heart
- Right side of heart: deoxygenated
- Left side of heart: oxygenated
- LORD: L - left side, O - oxygenated, R - right side, D - deoxygenated
- (IMPORTANT): veins usually carry most deoxygenated blood while arteries
carry oxygenated. BUT, pulmonary veins carry oxygenated while pulmonary
arteries carry deoxygenated.
- The diagram below shows where deoxygenated and Oxygenated blood goes
when it enters the body:

, - (VC: vena cava, RA: Right atrium, PValve: Pulmonary Valve)
DIAGRAMS:




Unit 2: Disease and immunity
- KEYWORDS:
- Homeostasis: body's ability to maintain internal stability.
- Incubation period: period before symptoms occur.
- Protist: feed on nutrients in ppl’s blood.
- Fungi: harmless and attack moist areas.
- Bacteria: Prokaryotic cells (no nucleus, no membrane).
