Ischemia is a condition in which blood flow in a tissue is insufficient to keep up with metabolic demand. a. true b. false

True

Explanation:

Ischemia is the reduction in blood flow to a tissue resulting in decreased oxygen and nutrient supplies to the tissue which may lead to cell death if not reversed.

Risk factors to ischemia includes:

1. Vascular diseases

2. Trauma

3. High blood pressure

4. Tobacco

5. Physical inactivity

6. High cholesterol.

Ischemia can be acute or chronic depending on its course of action. Acute ischemia occurs when there is a sudden decrease in the flow of blood to a tissue while chronic ischemia occurs when there is a gradual decrease in blood flow to a tissue.

Ischemia can be reversible when blood flow to the tissue returns. When irreversible, it leads to cell death.

is there any answer choices to this?

absolute strength refers to the maximum force exerted by a body irrespective of body size. relative strength on the other hand is the force exerted by a body in relation to muscle size or body weight.

so the answer is: c. absolute strength measures strength regardless of your body size, while relative strength measures strength adjusted for your weight.
