Question

Describe these 4 major events: pulmonary ventilation, external respiration, cardiovascular transport & internal respiration. Which uses diffusion vs. bulk flow? Know the bulk flow equation. What determines resistance?

Answer 1

-Pulmonary ventilation is commonly referred to as breathing

-External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air.

-Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells.

-cardiovascular transport is when Hormones are transported throughout the body via the blood's liquid plasma
