QUESTION 17 Which correctly describes the concentration gradient that exists for oxygen and carbon dioxide Oxygen concentration is higher in the lungs than in the blood returning from the body Oxygen concentration is higher in the tissues of the body than the blood coming from the lungs Carbon dioxide concentration is higher in the blood coming from the lungs than the tissues of the body Carbon dioxide concentration is higher in the alveoli than the blood returning from the body...

Question 6 (1 point) Which of the following statements are accurate? Oxygen is not the most abundant gas in the atmosphere. Diffusion of gases is 'better' across single cells that are thin than layers of thin cells. Gas exchange in humans occurs in the lungs at the structures called alveoli. Diffusion of gas occurs from areas with a higher partial pressure to an area of lower partial pressure. Organisms with gills may use a countercurrent exchange mechanisms to extract more...

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...

The lungs and the circulatory system cooperate to supply the body with oxygen and to remove carbon dioxide. In the table below, indicate the relative oxygen and carbon dioxide levels found in the listed structures by writing high, low, or being exchanged. Structure Oxygen Levels Carbon dioxide levels Left atrium / left ventricle Aorta /systemic arteries Systemic capillaries Systemic veins/ vena cavae Right atrium / right ventricle Capillaries surrounding alveoli Pulmonary artery Pulmonary vein Heavy smokers often develop abnormally high...

Question 1 During ventricular fibrillation, there is no coordinated ventricular contraction. What effect does this have on cardiac output? a. Increased cardiac output. b. Decreased cardiac output. c. No cardiac output. d. Cardiac output will remain normal. e. None of the above is correct Question 2 A “portal system” is the name for a. arteries that bypass a major organ. b. veins that bypass a major organ. c. two capillary beds in series. d. arteries that connect directly to veins...

A. . Hyperpnea would result in ___________________________ within the blood. an increase in both Pressure (oxygen) and Pressure (carbon dioxide) 2. Decreased Pressure (carbon dioxide) results in an increase in blood pH levels. Both of these conditions result in a shift of the oxygen-hemoglobin dissociation curve to the ______________________. This shift _______________ hemoglobin’s affinity for oxygen. select 3. Increased levels of 2,3 BPG occur in response to decreased blood pH levels. With all other variables unchanged, an increased concentration of...
