Which of the following is not a function of the skeletal system?

A) Locomotion
B) Production of erythrocytes
C) Storage of minerals
D) production of body heat

B) Production of erythrocytes – Erythrocytes are also known as RBC or red blood cells. Up to the age of 20 years, RBCs are produced from the red bone marrow of all the bones (long bones and all the flat bones)


C) Storage of minerals – The bones themselves are made of minerals and act as a mineral store for calcium and phosphorous

D) Production of body heat – As skeleton serves six functions, storage of minerals, movement, protection, support, production of blood cells, and endocrine regulations. Hence this is not a function of the skeletal system.
