Step-by-step explanation:
The subject of the question is Biology, specifically pertaining to the human body's excretory system and how it manages waste and water balance. The correct option for the question is 'C. removes cell waste,' as the process of sweating helps to remove waste products such as urea and salt from the body.
This process is controlled by the sweat glands and is influenced by various factors including body temperature and hydration levels. The kidneys also play a vital role in excretion, by filtering wastes and excess water from the blood to form urine, and in maintaining homeostasis by regulating water recovery and blood pressure.
Key Functions of the Kidneys
- The kidneys never stop filtering waste products from the blood and produce urine depending on the amount of fluid in the body.
- Through the production of the enzyme renin and various hormones like ADH, the kidneys regulate water recovery, which is essential for maintaining the body's fluid status.
- They also regulate the osmolarity of blood and key electrolytes like Na+, Ca++, and K+, and collaborate with other organs to regulate blood pressure.
