Lymphatic Respiratory systems 1.the direction that a gas diffuses is determined by   a. none of the choices are correct   b. the partial pressure of the gas on either side of a semipermeable membrane   c. the concentration of the solution into which the gas is dissolving   d. the solubility of the gas in the solution present on either side of a semipermeable membrane

8.  Identify the gradients (driving force) and resistance of each stage - Pulmonary Ventilation, Alveolar-blood gas exchange, Gas transport in the blood, Gas exchange at tissues.  Answer it like " The garadient of X is Y." " The resistance of X is Y."

eXam May The movement of gases across membranes in the lungs is Select one: O a. a passive process caused by differences in concentration O b. an exchange of molecules that is controlled by enzymes О с. a process that requires ATP O d. a chemical reaction involving oxygen

8. Explain the four stages of external respiration and identify the gradients (driving force) and resistance of each stage.  Answer like this - "the driving force of X is Y" The resistance of X is Z"

7. Causes of peripheral or pulmonary edema from a fluid-shifting perspective

28.  What is the function of the proximal histidine in hemoglobin?  MARK ALL THAT APPLY. Group of answer choices Prevents the oxidation of the iron in the heme prosthetic group Converts oxygen into carbon dioxide. Coordinates the iron in the heme prosthetic group. Prevents formation of superoxide ion. Stabilizes the bound oxygen through direct coordination.

4.Explain the concept of partial pressures of respiratory gases-oxygen, carbon dioxide, and nitrogen.

1. Is this statement correct or incorrect? Explain.  During strenuous exercise, the oxygen-hemoglobin dissociation curve shifts to the right. This rightward shift reflects an increase in the affinity of hemoglobin for oxygen and favors loading of O2 onto hemoglobin in the lungs. 2. Is this statement correct or incorrect? Explain.  Compared to hemoglobin, myoglobin has a lower binding affinity for O2 and a higher O2 binding capacity, two characteristics that allow myoglobin to efficiently provide skeletal muscle cells with a readily-accessible reservoir of O2.

36. Which of these does NOT directly influence oxygen loading and unloading? a. pH of the blood b. Concentration of 2,3-DPG in the blood C. Temperature of the blood d. Partial pressure of oxygen in the blood e. Partial pressure of oxygen in the cells

2. Describe how the walls of the airway structures change as you move from the trachea to the alveoli.3. What structures make up the conducting zone?
