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.
The inspiratory reserve volume measures the ___________ . amount of air remaining in the lung after a maximal exhalation amount of air that the lung holds amount of air that can be further exhaled after a normal breath amount of air that can be further inhaled after a normal breath
A partial pressure gradient of oxygen exists between ________. a. air and lungs b. lungs and metabolically active tissues c. air at sea level and air at high altitudes d. all of the above
Underwater, we humans cant compete with whales and other air-breathing marine mammals, which can stay submerged for extended periods. At the beach one day you meet a surfer who tells you that special training could allow her to swim underwater without breathing for an entire hour. From what you know of respiratory physiology, explain why she is mistaken.
49) Before air begins to exit the lungs (exhalation), after inhalation occurs: Group of answer choices The pressure in the alveoli increases Air flows into the lungs The volume of the alveoli stays the same 50) Refractory periods in cardiac muscle are longer in duration than in skeletal muscle. Group of answer choices False True 51) According to Henry’s Law, if the partial pressure of a gas increases, the amount of that gas that can dissolve in a liquid _______________. Group of answer choices Decreases Increases Stays the same 52) If oxygen decreases to very low levels, the heart responds initially by decreasing the heart rate. Group of answer choices False True
All human systems have the concept involving the flow of a molecule through system structures. (a) Using a flowchart (word, with > symbols), illustrate the path of air during exhalation. (b) Describe the muscular action of the diaphragm during exhalation. I forgot explain and tell me why
Trace the pathway of oxygen using the “Bunch of Grapes “model. Notethat air moves from the nose (nasal cavity), and mouth (oral cavity) to thetrachea, bronchi, bronchioles, and then into the alveoli (air sacs). Theair we breathe carries the gas oxygen. When we breathe, the oxygengoes to the lungs
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.
Air rushes into the lungs of humans during inhalation because O pulmonary muscles contract and pull on the outer surface of the lungs. O smooth muscle lining the trachea, bronchi and bronchioles contracts and causes their volume to increase. pressure in the alveoli increases. O the volume of the thoracic cavity increases. O the diaphragm contracts and pushes upward on the chest cavity. MacBook Air 888 F5 F6 F7 F2 F3 F4 @ #3 $ & 4 5 6. 8. W R Y F G J K C V M ommand
The “bends” or decompression sickness is a formof air embolism. When scuba or deep sea diversare under higher pressure, more nitrogen gasdissolves in the blood and tissue fluids. Usually aslow ascent to the surface (lower pressure) allowsthe gas to be gradually dissipated and exhaled. Ifa diver rises to the surface too rapidly, the gascomes out of solution, forming bubbles or gasemboli in the circulation. Explain why ischemiaand pain may occur in various tissues such asmuscle, joints, or the heart.
You cannot affect the oxygen delivery to your tissues by drinking “oxygenated water.” However, breathing oxygen at hyperbaric pressures does increase oxygen delivery to the tissues. Explain whythese two statements are true.
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
