A. Right lymphatic duct.Explanation
The correct answer is the right lymphatic duct. The lymphatic system is responsible for draining excess fluid and waste products from tissues and returning them to the bloodstream. Lymphatic vessels collect lymph, a clear fluid, from various parts of the body. The lymph then flows into either the thoracic duct or the right lymphatic duct. The right lymphatic duct specifically drains lymph from the right upper limb, right side of the head, and right thorax, and delivers it into the right subclavian vein, which is located near the heart. Therefore, the correct answer is the right lymphatic duct.Rate this question:

Correct Answer
A. Urethra.Explanation
The correct answer is urethra. The urethra is a tube that connects the urinary bladder to the external opening of the body, allowing urine to be expelled from the body. The urinary bladder stores urine until it is ready to be released, and the urethra serves as the passageway for urine to exit the body. The nephrons are the functional units of the kidneys, responsible for filtering waste products from the blood to form urine. The ureters are tubes that transport urine from the kidneys to the urinary bladder.Rate this question:
