The kidneys have the important job of filtering the blood to remove wastes.
The correct answer is:
- Filtering the blood to remove wastes.
The kidneys have the important job of filtering the blood to remove wastes. To understand this, we can break down the options provided:
O Reabsorbing water into the bloodstream: While the kidneys do play a role in regulating the body's water balance, their main function is not reabsorbing water into the bloodstream. It is more about filtering and removing waste products.
O Breaking down food mechanically: This is not the function of the kidneys. Food is broken down mechanically in the mouth through chewing or physically manipulating it.
O Producing bile to help digest fats: The production of bile occurs in the liver, not the kidneys.
O Filtering the blood to remove wastes: This is the correct answer. The kidneys act as a filtration system, removing waste products, excess water, and toxins from the bloodstream. They help regulate various substances in the body, such as electrolytes, pH balance, and blood pressure. The filtered waste and excess water are then excreted as urine.
