filtering the blood to remove wastes.
The correct answer is:
- Filtering the blood to remove wastes.
The kidneys play a crucial role in filtering the blood to remove waste products and excess water from the body. They help maintain the balance of chemicals, electrolytes, and fluid levels in the circulatory system.
The correct answer is: filtering the blood to remove wastes.
The kidneys play a crucial role in maintaining the body's overall balance and preventing the buildup of waste materials in the bloodstream. To arrive at this answer, we can eliminate the other options by understanding their functions and noting that they do not directly relate to the role of the kidneys.
1. Reabsorbing water into the bloodstream: While the kidneys do play a significant role in regulating the body's water balance, their main function is not to reabsorb water but to filter wastes from the blood.
2. Breaking down food mechanically: The process of breaking down food mechanically occurs primarily in the mouth and the digestive system, involving actions such as chewing and the muscular contractions of the stomach and intestines.
3. Producing bile to help digest fats: The production of bile primarily occurs in the liver, not the kidneys. Bile helps in the digestion and absorption of fats but is not directly related to the kidneys' function.
Hence, by process of elimination, we can conclude that the kidneys' primary job is to filter the blood to remove wastes.
