Question

Which part of the nephron is primarily responsible for filtration of blood?

• A. Loop of Henle
• B. Proximal convoluted tubule
• C. Bowman's capsule
• D. Collecting duct

Hint:

Bowman's capsule = Blood filtration. It is the first step in urine formation!

Answer 1

The Correct Option is C

To solve the problem, we need to identify the part of the nephron that performs the primary filtration of blood.

1. Understanding the Nephron:

- The nephron is the basic functional unit of the kidney.
- It is responsible for filtering blood, removing waste, and forming urine.
- Each nephron has several parts that carry out different functions.

2. Parts of the Nephron Involved in Filtration:

- Bowman's Capsule (Glomerular Capsule): A cup-shaped structure that surrounds the glomerulus.
- Glomerulus: A network of tiny blood capillaries inside Bowman's capsule.
- Together, the glomerulus and Bowman's capsule form the renal corpuscle.

3. Primary Filtration Process:

- Blood enters the glomerulus under high pressure.
- Water, salts, glucose, and waste products are filtered out of the blood through the walls of the glomerulus into Bowman's capsule.
- Large molecules like proteins and blood cells remain in the blood.
- This filtered fluid is called the glomerular filtrate, which then passes through the rest of the nephron.

Final Answer:

The part of the nephron primarily responsible for the filtration of blood is the glomerulus inside Bowman's capsule.
