The heaviest single internal organ housed in the human body is the?
Show answer Hide answer
Answer: B. Skin
Explanation
The human skin functions as the heaviest single internal and external organ housed in the body. It covers the entire exterior surface and accounts for a significant fraction of total body mass. Its extensive tissue expanse protects delicate internal structures from environmental damage. The integumentary system includes the skin, hair, nails, and associated exocrine glands. Skin tissue consists of multiple layers including the epidermis, dermis, and hypodermis. It acts as a vital sensory organ containing receptors for touch, temperature, and pain.
Severe burns damaging large areas of skin pose life threatening medical emergencies for patients. The skin synthesizes vitamin D when exposed to ultraviolet sunlight, supporting bone health. Dermatological assessments evaluate skin integrity to diagnose various systemic health conditions. The liver is the heaviest internal organ but weighs less than the total integumentary skin. The intestine is a long digestive tube with high surface area but lower overall tissue mass. The brain is a dense neural organ weighing roughly one point four kilograms in adults.
