Blood flow

Definition

Blood flow is the movement of blood through the circulatory system, facilitated by the pumping action of the heart. It ensures the delivery of oxygen and nutrients to tissues and the removal of waste products.

5 Must Know Facts For Your Next Test

1. Adequate blood flow is critical for efficient gas exchange in the lungs, which directly impacts pulmonary function.
2. Nutrients like iron are essential for maintaining healthy blood flow as they play a role in hemoglobin production.
3. Impaired blood flow can lead to conditions such as hypoxia, affecting respiratory efficiency.
4. Hydration status significantly influences blood viscosity and, consequently, blood flow and pulmonary function.
5. Chronic illnesses like COPD can alter normal blood flow patterns, necessitating careful nutritional management.
