Question

Water has the ability to dissolve salts and carry dissolved carbon dioxide. how does this action help the human body maintain homeostasis?

Answer 1

Homoeostasis is a system of maintaining balance. This is important because too much salt and the body can develop problems like high blood pressure, and edema. This increases the risk of a heart attack, strokes, dementia, and kidney disease. Then the dissolved carbon is unnecessary to the body.
 

Answer 2

Answer:

The carbon dioxide concentration will be constant by diffusion and the salt balance occurs by osmosis in human body. The maintenance of constant internal environment is homeostasis.

Explanation:

Homeostasis is the process of keeping a constant internal environment. Here all the physiological activities should be at a constant level. This includes the maintenance of the blood sugar level, carbon dioxide concentration, salt, temperature regulation.  

The salt balance is maintained in the body by aldosterone hormone or ADH hormone. It is a steroid hormone secreted from the adrenal cortex. When the salt concentration is more in the blood, aldosterone secretion will be more. It helps to reabsorb more salt by the distal convoluted tubule.  

When the salt concentration is less in the body the secretion of the ADH hormone is less. This maintains the osmoregulation of the body by keeping the sodium level constant.  

Another example is the maintenance of carbon dioxide concentration in the blood. In the blood, the carbon dioxide concentration is less than the oxygen. Sometimes due to physical exercise, cellular respiration increases the level of carbon dioxide.  

In this situation, the medulla oblongata sends the signal to the heart. Then the heart helps carry more carbon dioxide in the blood and reaches the lungs. Thus the heartbeat and breathing rate will more. This expels out the excess carbon dioxide from the body.  

This process happens by diffusion while the salt balance has done by osmosis.
