Please discuss below how the relaxation of smooth muscle will alter lung capacities, with special attention given to how relaxation will impact airway diameter, airway resistance, and oxygen uptake (inspiration/inhalation)
After light exercise, the oxygen consumed in recovery is approximately equal to the oxygen deficit, which is the amount of additional oxygen that would have been consumed had oxygen consumption reached steady state immediately. How is the oxygen consumed in recovery used?
how does the body increase oxygen availability at high altitude?

- Which energy system did you use for 5 mins of jogging (around the house or up/down the stairs)? what is the main sourse of energy for ATP replenishment for this system? What is the limitation of this energy sourse? What muscles fibres recruited? A) ATP-PC system B) Glycotic system (Glycolysis - pyruvate) C) Cellular Respiration (Aerobic Respiration - ETC)arrow_forwardSome patients with severe emphysema have constant high levels of carbon dioxide because of inadequate ventilation. The central nervous system breathing center in these patients becomes insensitive to carbon dioxide and more dependent on the level of oxygen, which is low. These patients are said to have “oxygen-dependent respiratory drive". What might happen if you give such a person high levels of supplemental oxygen? Essay Toolbar navigation BIU S > > > !!!arrow_forwardWhich of the following statements regarding control of respiration is TRUE? At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.arrow_forward
- How do breathing (ventilation) and pulse rates respond to exercise? Why?arrow_forwardHow does an uncoupler of respiration work?arrow_forwardThe movement of air out of the lungs during normal expiration is a result of? Air moves out of the lungs due to the relaxation of the diaphragm and intercostal muscles. Air moves out of the lungs due to the passive elastic recoil of the chest wall and lungs. Air is forced out of the lungs due to the active contraction of the abdominal and external intercostal muscles. Air is forced out of the lungs due to the active contraction of the abdominal and internal intercostal muscles.arrow_forward
- describe the relationship between oxygen consumption & oxygen uptake, and between carbon dioxide production & carbon dioxide unloading? please describe in detail.arrow_forwardBecause flight is metabolically demanding, birds have very efficient systems that help to meet these demands. Look at the following list of characteristics and choose those that contribute to the physiological demands of flight. One-way airflow respiration Endothermy Large heart Nucleated red blood cells Slow heart rate Two-cycle lung ventilation Air sacs Separate pulmonary / systemic circulation Air capillariesarrow_forwardYou mention is it beneficial to train in high altitudes. Which physiological changes occur in the body in response to lower partial oxygen pressures?.. .arrow_forward
- What neural afferents might also contribute to the regulation of ventilation during exercise?arrow_forwardWhat muscle groups are involved in ventilation during rest? During exercise?arrow_forwardtion Completion Status: accumulation of "waste products" in cells can damage important substances (like collagen) and disrupt normal physiological processes. QUESTION 17 Lungs: With age, lung function becomes "less efficient." Which one does not explain why? Lung tissue becomes more "elastic" resulting in less expansion. O There is a decrease in "reserve capacity" that affects stamina. There is a decrease in the number of airs sacs for oxygen transport. O Muscles in the rib cage become weaker and reduce contraction.
