Question

which of the following is not a function of skeletal muscle?
a maintaining body temperature
b guarding entrances and exits
c producing skeletal movement
d phagocytosis
e maintaining posture

Explanation:

Skeletal muscles help in maintaining body temperature (through heat production during contraction), guarding entrances/exits (e.g., orbicularis oris around mouth), producing skeletal movement (attached to bones), and maintaining posture. Phagocytosis is a function of certain immune - cells (like macrophages) where they engulf and digest pathogens or debris, not a function of skeletal muscle.

Answer:

D. phagocytosis
