Question

lo 4.3 what are the six functions of the skeletal system?
contract to produce movement, sustain body posture and position, maintain body temperature, store nutrients, and stabilize joints.
regulate body temperature, produce digestive enzymes, protect internal organs, store fat, and maintain fluid balance.
produce red blood cells, regulate electrolyte balance, support the respiratory system, store minerals, and protect the cardiovascular system.
produce hormones, support the lymphatic system, regulate ph balance, store glycogen, and aid in thermoregulation.
transport oxygen to cells, protect the nervous system, support the immune system, store blood cells, and regulate hormone levels.

Explanation:

The skeletal system produces red blood cells in bone - marrow, helps regulate electrolyte balance, supports the respiratory system by providing a framework for muscles involved in breathing, stores minerals like calcium and phosphorus, and protects vital organs related to the cardiovascular system. The other options list functions that are not primary functions of the skeletal system. For example, producing digestive enzymes is a function of the digestive system, and transporting oxygen is mainly a function of the circulatory system.

Answer:

produce red blood cells, regulate electrolyte balance, support the respiratory system, store minerals, and protect the cardiovascular system.
