Which of the following organs filters excess solutes from the blood?

Rationale

Kidney filters excess solutes from the blood.

The kidney is responsible for filtering blood, removing excess solutes, waste products, and maintaining fluid balance in the body. It plays a crucial role in regulating electrolytes and excreting urine, ensuring the body’s internal environment remains stable.

A (Stomach) YOUR ANSWER

The stomach primarily functions in the digestion of food through the secretion of gastric juices. It breaks down food and prepares it for further digestion and absorption in the intestines. While it does play a role in nutrient processing, it does not filter solutes from the blood.

B (Kidney) CORRECT

The kidney is the organ that filters blood to remove excess solutes, waste, and toxins. It regulates the body’s fluid and electrolyte balance through the processes of filtration, reabsorption, and secretion, making it essential for maintaining homeostasis.

C (Gallbladder) YOUR ANSWER

The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine to aid in the digestion of fats. It does not filter blood or excess solutes; rather, it assists in the digestive process by facilitating fat absorption.

D (Spleen) YOUR ANSWER

The spleen is involved in filtering blood, specifically by removing old or damaged red blood cells and recycling iron. While it has a role in blood filtration, it does not primarily filter excess solutes like the kidneys do. Its main functions are related to immune response and blood cell regulation.

Conclusion

The kidney is the primary organ responsible for filtering excess solutes from the blood, ensuring fluid balance and waste removal. While other organs like the stomach, gallbladder, and spleen have important roles in digestion and blood regulation, they do not perform the same function as the kidneys in filtering blood. Understanding the specific functions of each organ is crucial for grasping their contributions to overall health and homeostasis.
