Which of the following organs regulates the levels of water. salts, hydrogen ions, and urea in the mammals?
Answer Details
The organ that regulates the levels of water, salts, hydrogen ions, and urea in mammals is the kidney. The kidney is a vital organ responsible for filtering waste products from the blood and producing urine, which is then excreted out of the body. The kidney achieves this through a complex system of tubules and nephrons that filter the blood and reabsorb necessary substances while eliminating excess water and waste products such as urea.
The kidney's primary role is to maintain the body's homeostasis, which involves regulating the levels of water, salts, hydrogen ions, and urea in the body. The kidney helps to balance the amount of water in the body by regulating the production and excretion of urine. The kidney also regulates the levels of salts, such as sodium, potassium, and calcium, in the body to ensure they remain within a healthy range. Additionally, the kidney helps to regulate the body's pH level by controlling the levels of hydrogen ions in the blood. Finally, the kidney eliminates excess urea, a waste product produced by the breakdown of proteins in the body, by filtering it out of the blood and excreting it in the urine.
In summary, the kidney is the organ that regulates the levels of water, salts, hydrogen ions, and urea in mammals. It achieves this through a complex system of tubules and nephrons that filter the blood and reabsorb necessary substances while eliminating excess water and waste products such as urea.
