Final answer:
General anesthesia induces various physiological changes, including alterations in respiration, intestinal peristalsis, aldosterone secretion, and blood volume. The muscles necessary for breathing may relax under anesthesia, which can be managed through endotracheal intubation. These changes may vary depending on factors such as age and weight.
Step-by-step explanation:
General anesthesia elicits several physiological changes in the body. These include increased minute respiration, decreased intestinal peristalsis, decreased aldosterone secretion, and increased blood volume. Additionally, under anesthesia, the muscles necessary for breathing may relax, potentially blocking the airway, which can be addressed through endotracheal intubation. It is important to note that these physiological changes may vary depending on individual factors such as age and weight.
