Which system, comprises of skin hair, and other parts of the outer most layer of the body A)lymphatic system,
B)integumentary system
C)nervous system
D) endocrine system
B) Integumentary system
The system that comprises the skin, hair, and other parts of the outermost layer of the body is the B) integumentary system.
The correct answer is B) integumentary system.
To arrive at this answer, we can break down the options and analyze which one fits the description.
A) The lymphatic system is responsible for maintaining fluid balance and fighting infections. It consists of lymph nodes, lymph vessels, thymus, spleen, and tonsils. While the skin is involved in the immune response, the lymphatic system as a whole does not include components like hair or other parts of the outermost layer of the body. Therefore, the lymphatic system is not the correct answer.
B) The integumentary system is the system that includes the skin, hair, nails, and glands. It is responsible for protection, regulating body temperature, sensation, and the production of Vitamin D. The integumentary system perfectly matches the description of the system that comprises the skin, hair, and other parts of the outermost layer of the body. Therefore, the correct answer is B) integumentary system.
C) The nervous system is responsible for transmitting signals throughout the body, allowing for communication and control. While the skin contains nerve endings that help with sensory perception, the nervous system as a whole includes the brain, spinal cord, and peripheral nerves. Therefore, the nervous system is not the correct answer.
D) The endocrine system is responsible for producing and releasing hormones that regulate various body functions. It includes glands such as the pituitary gland, thyroid gland, adrenal glands, and others. While the skin plays a role in the production of Vitamin D, it does not primarily function as an endocrine organ. Therefore, the endocrine system is not the correct answer.
In conclusion, the correct answer is B) integumentary system, as it includes the skin, hair, and other parts of the outermost layer of the body.
