Functions of the Kidneys
The kidneys are vital organs in the human body, responsible for multiple functions that maintain homeostasis. They filter blood, regulate fluids, and excrete waste products.
Role in Absorption of Nitrogenous Wastes
- Kidneys do not absorb nitrogenous wastes; instead, they excrete them.
- The main nitrogenous wastes include urea, creatinine, and uric acid, which result from protein metabolism.
- These wastes are filtered from the blood in the nephrons and eliminated through urine.
Homeostasis
- The kidneys help maintain homeostasis by regulating the volume and composition of body fluids.
- They adjust the concentration of electrolytes and maintain the balance of water in the body.
Maintenance of pH
- Kidneys play a crucial role in acid-base balance.
- They secrete hydrogen ions and reabsorb bicarbonate to maintain blood pH within a narrow range.
Maintenance of Salt Contents
- The kidneys regulate sodium, potassium, and calcium levels, ensuring that the body has the right balance of salts.
- This regulation is crucial for processes like muscle contraction and nerve signaling.
Conclusion
- The correct answer is option 'A' because kidneys do not absorb nitrogenous wastes; they are responsible for their excretion.
- Understanding the primary functions of the kidneys is essential for comprehending their role in overall health and homeostasis.
