Question

Out of the following, choose the correct path of urine in our body.

• A. Kidney→ ureter→ urethra →urinary bladder
• B. Kidney →urinary bladder →urethra→ ureter
• C. Kidney →ureter→ urinary bladder →urethra
• D. Urinary bladder →kidney→ ureter →urethra

Answer 1

The correct option is C

Kidney →ureter→ urinary bladder →urethra

The correct option is C.

The explanation for the correct option:

1. The major organ of the human excretory system is the kidney.
2. Through microscopic filtering organs called nephrons, the kidneys draw urea, excess water, and ions from the blood to create urine.
3. Urine is produced in the kidney and then leaves the kidneys through the ureters to be deposited in the bladder.
4. Urine leaves the body through the urethra when someone urinates, leaving the bladder.
5. Hence, the correct pathway for the urine is the Kidney →ureter→ urinary bladder →urethra.

Kidney:

1. The kidneys are bean-shaped structures that are positioned on either side of the backbone and are protected by the ribs and back muscles.
2. Each adult human kidney measures 10–12 cm in length, 5-7 cm in breadth, and weighs about 120–170 g.

Ureter:

1. The ureter, a pair of skinny muscular tubes, emerges from each kidney's renal pelvis.
2. From the kidney to the bladder, it transports urine.

Urinary Bladder:

1. Urine is kept in this muscular sac-like structure.
2. Micturition, or the act of urinating, is the process by which the urine bladder is emptied.

Urethra:

1. This tube, which emerges from the urinary bladder, aids in the removal of urine from the body.
2. It serves as the typical pathway for sperm and urine in males.

Final Answer: The correct path of urine in our body is: Kidney →ureter→ urinary bladder →urethra.
