6. The system that creates movement  - Muscular system

Explanation:

Hormones:

Adrenaline or epinephrine: Released by: Adrenal glands

Function: Prepare the body in fight or flight response and hence accelerates heart rate, blood pressure enlarges pupil, expands air passages in lungs in preparation to that response.

Cortisol: Released by: Adrenal glands

Functions: Regulate metabolism and controls the blood glucose level; activates immune response; prepares body to respond to stress. An increase in cortisol level can narrow down or constrict the arteries and increase the blood pressure.

Estrogen: Released by: Ovaries

Function: Female sex hormones which develop feminine characteristics in females like breast and hair (underarm and pubic areas) development during puberty, protects the bone health, controls cholesterol, and activates body systems.

Body systems:

The circulatory system is a transport system complete with heart, blood and all the blood vessels. This system transports oxygen, nutrients, hormones, and other substances throughout the body and supplies all its tissues via blood travelling through the blood vessels. This also carries carbon dioxide and other waste products out from the body cells.

The skeletal system complete with bones and joints provides the supportive framework of the body which provides body shape and protects all the internal organs are present inside the framework. It also helps to synthesize RBCs in the bone marrow and helps to store minerals.

The muscular system complete with muscles and connective tissues aids in body movements both voluntary and involuntary and maintains posture.
