Homeostasis
• Homeostasis is the maintenance of relatively stable internal
environment
Environment
External
• The surrounding environment of the
organism
Internal
• The ECF
• Fluid that surrounds the cell → to
exchange materials
Advantages
1. Increased chances of survival
2. Ability of living in different
climactic conditions
3. Proper brain function
, Factors maintained
1. Nutrient concentration
2. Water & electrolyte concentration
3. Waste product concentration
4. Oxygen (100mm/hg) & carbon dioxide
(40mm /hg) partial pressure
5. PH → 7-4
6.blood volume → 4-6L
7. Blood pressure → 120/80 mm Hg
8. Temperature → 37°C
Systems involved
1. Circulatory → transportation of
nutrients & wastes diffusing between
tissue
2. digestive → breaking of nutrients to
be absorbed
3. Respiratory → obtaining of oxygen &
removal of carbon dioxide
4. Urinary → removed of waste & excess
water & salt
