Question

Glomerular hydrostatic pressure is present in.

• A. Malpighian tubule
• B. Bowman’s capsule
• C. Tubule of the kidney
• D. Glomerulus of urinary tubule

Answer 1

The correct option is D

Glomerulus of urinary tubule

The correct option is D.

Explanations of correct option:

Option D:

1. The glomerulus of the urinary bladder is a tuft of capillary tubules that help in the filtration of toxic waste from the blood.
2. The ultrafiltration creates a high hydrostatic pressure that helps in the filtration of major proteins, and blood cells are filtered.
3. The glomerular filtrate is created based on a pressure gradient.

Explanations of incorrect options:

Option A:

1. The excretory system of insects is known as the Malpighian tubule.
2. It is present in the abdominal cavity of insects.
3. These are free-floating organs.
4. They also help in osmoregulation, which is the maintenance of salt, ion, and osmotic balance.

Option B:

1. Bowman's capsule is a thin layer of epithelial cells that covers and encapsulates the glomerulus of a nephron.
2. It helps to create a space from where the filtrate can enter into the proximal convoluted tubule.

Option C:

1. The kidney tubule is a long tubular structure that helps in the reabsorption of ions and water.
2. It has various parts such as proximal convoluted tubule (PCT), descending loop of Henle, ascending loop of Henle, distal convoluted tubule, and collecting duct.
3. Descending loop of Henle is permeable to water hence helping to create concentrated urine.
4. The ascending loop of Henle is impermeable to water hence helping in the absorption of salt and ions.
5. Collecting duct collects the urine to transfer to ureters.

Final answer: Glomerular hydrostatic pressure is present in the Glomerulus of the urinary tubule.
