ANSWER
Bulk flow is the term referring to the movement of air into and out of lungs. Gases move from high-pressure area to a low-pressure area. This bulk flow of air from the outside environment to the alveoli of lungs happens due to pressure changes in the lungs. The movement of air into and out of the lungs is dependent on the partial pressure of Oxygen and Carbon dioxide. During inspiration, the partial pressure of oxygen in the environment is higher than that of the alveolus, so there is a bulk flow of oxygenated air from the environment to the alveoli. Similarly in the process of expiration as the partial pressure of Carbon dioxide is higher in the alveoli than that of the external environment, there is a bulk flow of carbon dioxide to the external environment.

Epinephrine causes muscles to contract and the heart and lungs to increase respiration and blood flow. In combination with epinephrine causing glucose production and secretion from the liver, how does epinephrine elicit a system wide response? Multiple Choice A.) Glucose provides energy for muscle contractions, which are stimulate by high concentrations of oxygen. Oxygen is provided by the increase in respiration and blood flow. B.) Glucose provides energy for muscle contractions, resulting in high levels of pyruvic acid. The pyruvic...

Please answer to the part A,B,C
of the question below
In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 494 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1980 mL and a single respiratory cycle for an average human takes about 4 seconds.

Name 13. During gas exchange in the lungs, several factors affect the rate of gas diffusion across alveolar (the alveoli are tiny air sacs in the lungs) and tissue membranes. One of the factors is the difference in partial pressures of the gases across the membranes. The gases will diffuse from an area of high partial pressure to an area of low partial pressure, Look at the illustration below and note which blood vessels carry blood away from the lungs...
