The decreased activity and demand for oxygen is a major factor predisposing to pulmonary infection in immobilized patients
Some of the most common the pulmonary infections is like: Empyema – The presence of the pus within the pleural space and in between the lungs and the chest wall. the Lung abscess – A pus-filled cavity within the lung is surrounded by the inflamed tissue. Tuberculosis – A bacterial infection of lungs.
A lung infection can also be caused by the virus, bacteria, and sometimes even a fungus. One of the most and common types of lthe lung infections is called pneumonia. Pneumonia, in which the affects of the smaller air sacs of the lungs, is most often caused by the contagious bacteria, but they can also be caused by the virus.

Answer: Homeostasis refers to stability, balance, or equilibrium within a cell or the body. It is an organism’s ability to keep a constant internal environment. Homeostasis is an important characteristic of living things. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis can be thought of as a dynamic equilibrium rather than a constant, unchanging state.
Feedback Regulation Loops
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
Feedback regulation occurs when the response to a stimulus has an effect of some kind on the original stimulus. The type of response determines what the feedback is called. Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.

Answer:
We should drink water while we exercise because when we exercise, we sweat out part of the water we have in our bodies. Water is important to our everyday life, and when we become tired and overheated, water helps us to cool down, and it also helps replace the water we lose from sweat.
