Give two examples of how the integumentary system, skeletal system and muscular system interact.

Skeletal system is composed of axial , appendicular skeleton & teeth.Axial skeleton includes skull bones, rib cage & spinal cord.Appendicular skeleton include arm bones & leg bones.

Relation to the Integumentary System:

Vitamin D is important for strong bones.Its absorption takes place through the skin to work with calcium for the maintenance of healthy bones.

Relation to the Muscular System:

acts as a support system for body

works with muscles to move the limbs

gives muscles something to pull against

Muscular System: It includes muscles. It works with nervous system to move the body.

Relation to skeletal system:

Skeletal muscles move the bones

Tendons connect muscles to bones

Relation to Integumentary System:

expulsion of sweat when muscles are in use

Integumentary System:

It includes skin, hairs and nails.It is throughout the entire body. The main function is the protection from outside invaders. Skin is first line protector for the body.

Relation to Muscular System :

Muscles are protected by skin

Sweat glands present in the skin results in sweat expulsion due to muscle contraction

Relation to Skeletal system:

Bones protection

Vitamin D is formed by the skin which is very much important for absorption of calcium in the bones.

the correct answer is:

a population changes in response to a change in the environment.
