WebThe pressure gradient drives CO 2 out of tissue cells and into the capillaries. The blood returning to the lungs through the pulmonary arteries has a venous P O2 = 40 mm Hg and a P CO2 = 45 mm Hg. The blood enters the lung capillaries where the process of exchanging gases between the capillaries and alveoli begins again (Figure 20.13). WebPulmonary ventilation is dependent on three types of pressure: atmospheric, intra-alveolar, and interpleural. Atmospheric pressure is the amount of force that is exerted by gases in the air surrounding any given surface, such as the body. Atmospheric pressure can be expressed in terms of the unit atmosphere, abbreviated atm, or in millimeters of mercury … WebApr 14, 2024 · Omphalocele is the most common ventral abdominal wall defect.

An "electrochemical gradient" is a combination of two factors: an "electrical potential difference" between the inside and outside of the membrane and a "concentration gradient." In Khan's example, the "electrochemical graident" is established due to the sodium/potassium pump and the carrier protein's ability to allow potassium to travel ...

WebStimulated by the action of the ions on its receptors, the pump transports them in opposite directions against their concentration gradients. If equal amounts of Na + and K + were transported across the membrane by the pump, the net charge transfer would be zero; there would be no net flow of current and no effect on the membrane potential.
