Describe the four respiratory processes - ventilation, external respiration (gas exchange at lung), internal respiration (gas exchange at body tissues), and cellular respiration.

The alveolar walls are composed of two types of cells type I and type II pneumocytes. The function of type II cells is to O increase surface tension O secrete surfactant O decrease surface tension O trap dust and other debris O b) and c) O b) and d)

Describe the four processes of external respiration.

Which of the following can be included as part of internal respiration? 1. Gas exchange from the alveoli to the capillaries  2. Gas diffusion from alveoli to the red blood cells 3. Cells taking up oxygen to be used for cellular respiration

How can problems with ventilation could affect someone's ability to carry out cellular respiration. *

Which of the following factors would NOT increase the rate of diffusion of oxygen through the respiratory membrane? A) Increasing the SA/V ratio B) Increasing the partial pressures C) Decreasing the surface area D) Decreasing the thickness of the membrane E) Decreasing the distance the gas has to diffuse

The inhalation and exhalation are two characteristics of respiratory function. Please explain the concept of ventilation versus respiration, and explain the characteristics of inspiration and expiration in terms of involved organs and the forces triggering them.

Define and distinguish between these four respiratory processes:pulmonary ventilationexternal respirationinternal respirationcellular respiration

Give any three differences between External respiration and Internal respiration?

Match the following statements about ventilation and respiration with whether it is true or false  A)intrapulmonary pressure must be higher than atmospheric pressure in order to inhale B)as the volume of a vessel increases, the pressure decreases C)the presence of a thin layer of fluid between the parietal and visceral pleura allows us to increase the size of our lungs D)exhaling is an active process requiring muscle contraction E)elastic recoil decreases the volume of the lungs
