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?

-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
