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

well, since there is no answer choices, i will give an answer on how it works : )

the two objects are placed together. energy will always be transferred from the hotter object to the cooler object until they are equal. hope this is close to one of the answer choices : )
