If water passed over the gills of fish in the same direction as blood flow through the capillaries, how would gas exchange be affected? Select all correct choices. More oxygen would diffuse from the water into the fish's bloodstream. Less oxygen would diffuse from the water into the fish's bloodstream. More carbon dioxide would diffuse out of the fish's bloodstream into the water. Less carbon dioxide would diffuse out of the fish's bloodstream into the water. Gas exchange would remain the same, regardless of the direction of water flow.

Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air? Air in the lung is humidified; therefore, water vapor pressure alters the pressure Carbon dioxide mixes with oxygen Oxygen is moved into the blood and is headed to the tissues Lungs exert a pressure on the air to reduce the oxygen pressure.
Breathing _______. a. ventilates the lungs b. draws air into airways c. expels air from airways d. causes reversals in pressure gradients e. all of the above
Gas exchange is more difficult for aquatic animals with gills than for terrestrial animals with lungs because CHECK ALL THAT WOULD APPLY water contains much more O2 per unit volume than air gills allow water to flow in one direction. water contains much less O2 per unit volume than air gills have less surface area than lungs. water is denser than air
In amphibians, cutaneous gas exchange is particularly important, especially in some species of lungless salamanders. Draw the circulation of oxygen-rich and oxygen-poor blood during cutaneous gas exchange for a lungless salamander. Upload your image (may be hand drawn or digitally rendered).
Which of the following control breathing? select all that apply Centers in the Pons and Medulla control breathing Respiratory centers respond to changes in acid base Chemoreceptors respond to a decrease in oxygen Chemoreceptors are located in the heart and lungs
Put the following in order by numbering from 1 to 5 - Diaphragm contracts and flattens and ribs elevate - The diaphragm returns to its dome shape resting position - The thoracic cavity increases in volume - Air inters the lungs due to a lower pressure gradient than atmospheric pressure - A subatmospheric pressure is created in the lungs
I. Animal A. Complete the given table on animal gas exchange. Types of Respiration Plasma membrane Body wall/skin Tracheal system Gills Lungs Description
you can create a bar graph or a line graph to represent the respiratory volumes and capacities measured using a wet spirometer. The x-axis can represent the different volumes and capacities measured, and the y-axis can represent the values in liters. You can use different colors or patterns to represent the different measurements taken for each individual
Which of the following is true of the regulation of breathing in humans? Select all that apply. Check All That Apply The concentration of oxygen in the blood is the primary regulator of breathing rate. Breathing can be controlled consciously but is usually subconsciously controlled by the brain. A compound that lowers blood pH would increase respiration rate. Increased levels of blood carbon dioxide lead to an increase in bicarbonate production, which buffers the blood, making it harde oxygen to enter tissues. Respiration increases with the increased production of carbon dioxide during exercise.
How many steps (inhalations/exhalations) are needed to complete one ventilatory cycle in birds? O 3 breaths in/3 breaths out O 2 breaths in/2 breaths out O More than 4 of each O 1 breath in/1 breath out O 4 breaths in/4 breaths out
