Question

____________ of many nephrons open into a straight tube called collecting duct.

• A. Distal convoluted tubules
• B. Proximal convoluted tubules
• C. Bowman’s capsule
• D. Henle’s loop

Answer 1

The correct option is A Distal convoluted tubules

Bowman’s capsule is found in the outer part of the kidney, the cortex. It encloses the glomerulus which helps in the filtration of blood.
The filtrate from the glomerulus passes through the renal tubules of the nephron in the following order - proximal convoluted tubule, Henle' s loop and the distal convoluted tubule. Reabsorption occurs in the renal tubules and then the distal convoluted tubules of many nephrons open into a straight tube called collecting duct.
So the collecting duct collects urine from the nephrons and moves it into the renal pelvis and ureters. Ureters carries the urine to the urinary bladder and it is excreted from the body.
