Perfusion

Definition

Perfusion is the process by which blood is delivered to tissues, ensuring they receive necessary oxygen and nutrients. Proper perfusion is essential for maintaining healthy organ function and overall homeostasis.

5 Must Know Facts For Your Next Test

1. Perfusion is critical for delivering oxygen and nutrients to the cardiovascular system, directly influencing heart health.
2. Poor perfusion can lead to ischemia and subsequent tissue damage or organ failure.
3. Nutritional status can significantly affect perfusion by altering blood viscosity, vessel elasticity, and overall cardiovascular health.
4. Hydration levels are vital for optimal perfusion as dehydration can reduce blood volume and impair circulation.
5. Certain nutrients like omega-3 fatty acids can improve endothelial function, thus enhancing perfusion.
