Solution: The oxygen dissociation curve is a graph that shows the percentage of oxyhemoglobin saturation at different partial pressures of oxygen.The partial pressure of oxygen in the lungs is very...
Solution: The trachea is an insect's respiratory organ. Air enters the trachea through spiracles, which are small apertures. Spiracles can be seen on either side of the insect's abdomen. Each...
Solution: Inspiration is the process of allowing fresh air to enter the lungs. Inspiration occurs when the intrapulmonary pressure (pressure in the lungs) is lower than the atmospheric pressure. The...
Solution: The alveoli present in the lungs are small air sacs that allow the fast exchange of gases. The alveolar membrane has a total thickness of less than a millimeter, and the outside surface of...
Carbon dioxide is transported by plasma and red blood cells. This is due to their high water solubility.(1) Through plasma: 7% of $C{{O}_{2}}$ is transported in a dissolved state by the plasma....
Solution: The volume of air exhaled or inhaled during typical respiration is referred to as tidal volume (TV). For a healthy person, the tidal volume is roughly 500ml. A healthy person may exhale or...
Solution: The differences between all the following sets are as follows: (a) IRV and ERV IRV (Inspiratory reserve volume)ERV (Expiratory reserve volume)It's the amount of air that a person can...
Solution: Hypoxia is a situation in which the supply of oxygen to the lungs is insufficient or reduced. Several external factors, such as a decrease in pO2, insufficient oxygen, and so on, induce...
Solution: The altitude rises as we go higher. The concentration of atmospheric oxygen is lower at this height, implying that the partial pressure of oxygen decreases. The lack of oxygen in this...
on oxygen transport?Solution: In the oxygen transport mechanism, $pC{{O}_{2}}$ plays a critical function. Oxyhaemoglobin is formed when low $pC{{O}_{2}}$ levels in the alveoli cause oxygen to bind to hemoglobin and...
Solution: The respiratory rhythm center in the medulla area of the brain is in charge of controlling the breathing process. The pneumatic center can change the function of the respiratory rhythm...
Solution: When comparing the pO2 and pCO2 in atmospheric air to those in alveolar air, (ii) pO2 will be higher and pCO2 will be lower. Each gas in a combination exerts a pressure known as partial...
Solution: The functional residual capacity can be used to express it (FRC). The volume of air that remains in the lungs following a normal expiration is referred to as the FRC. The expiratory...
Solution: The maximum volume of air a person can breathe in after a forced expiration is known as vital capacity. It is equal to the sum of inspiratory reserve volume (IRV), tidal volume (TV), and...
