In a countercurrent exchange system, where along the blood vessel would most oxygen diffuses from the water into the blood? Where would this occur in the concurrent exchange system?
Homework Answers
Coutercurrent exchange system occure in fish.Fish gills use ‘countercurrent oxygen exchange’ to maximize the amount of oxygen that their blood can pick up The gill is where fish absorb oxygen from the surrounding water into their blood. However, oxygen can only diffuse into the blood at the gills if the oxygen level is higher in the water than in the blood.

4. Capillaries are by far the most common type of blood vessel in the body, and most capillaries are very porous-they leak fluid. Blood is mostly fluid. The swelling caused by fluids leaking from the blood into tissues is known as edema. Predict where in the body you would see edema related to left-sided heart failure, and where you would see edema related to right-sided heart failure. Be sure to explain your answers.

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...

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...
