Question

question 5
which of the following is not a function of the skeletal system?
a blood cell formation
b protection of internal organs
c communication
d mineral storage

Explanation:

The skeletal system has several functions. Red bone marrow within bones is involved in blood cell formation (hematopoiesis), so option A is a function. Bones protect internal organs (e.g., the skull protects the brain, ribs protect the heart and lungs), so option B is a function. Bones store minerals like calcium and phosphorus, so option D is a function. Communication is mainly a function of the nervous system (using neurons to send signals) and the endocrine system (using hormones), not the skeletal system.

Answer:

C. communication
