Introduction:
The integumentary system comprises of skin, nail, hair, assorted glands, and the subcutaneous tissue below the skin. The function of the integumentary system is to provide protection to the inner body and maintain the function. For example, the skin keeps the body away from harmful substances and also prevents the loss of essential fluid, the subcutaneous tissue connects the underlying tissues like muscles to the skin, the hairs in the head protects the scalp from heat and cold by providing insulation.
Answer to Problem 4STP
Correct answer:
The correct answer is option (A) cover the body surface and protect its tissue.
Explanation of Solution
Explanation/justification for the correct answer:
Option (A) covers the body surface and protects its tissue. The epithelial tissue is the outermost tissue of the integumentary system which consists of skin the largest organ of the human body. The skin keeps the body away from harmful substances and also prevents the loss of essential fluid. So, the correct answer is option (A).
Explanation for incorrect answer:
Option (B) move joints and bones. The movement of joints and bones is conducted by the skeleton muscles. The voluntary muscles maintain the movement of the body. The joints and bones movement is not a function of epithelial tissue. So, this is an incorrect option.
Option (C) provides a structural framework for the body. The structural framework of the body is maintained by the skeleton system. It consists of bones that give the body a proper structure and also holds the organs intact. So, this is an incorrect answer.
Option (D) transmit nerve signals. The transmission of the nerve signal is maintained by the neurons or by the nervous system. So, this is an incorrect answer.
