Tell whether the following statement is true or false: If a cell does not make adaptive changes as a result of tress, it will die: How does Hypoxia cause cell damage? Two boys suffered hypoxia: one was at normal body temperature and the other was cold. Which one will have a lower intracellular pH? Which one will have more cell swelling? Mr. X had a stroke. Blood flow to part of his brain was cut off. His wife can understand why they gave him anticoagulants, but she does not comprehend why he was also put on: Oxygen and Calcium Channel Blockers. What is the explanation? Tell whether the following statement is true or false: Necrotic cells may be reversed using high concentrations of oxygen. Which type of gangrene results in (crepitus) bubbles that can be felt under the skin?

Solution

1. true. cell makes adaptive changes to adjust the stress.

2. Hypoxia means lack of oxygen. this may be due to ischemia or obstruct bloos supply to tissues or organ. oxygen is important to generate energy in the living cells. lack of oxygen makes the cells energy deficient that are unable to maintain biological processes and structural integrity result in cell damage.

3, in first case body temperature is same due to same metabolic rate but in hypoxia condition it it will cause lactic acid production which will lower the intra cellular PH.

in another case body was cold due to vasoconstiction. this means body need more energy to maintain its temparature. the cell swelling will occur.

4. oxygen was provided to make most supply to tissues to make energy and calcium blocker is required to prevent cell damage and ATP depletion.
