Answer:
I can not answer this question, I do not know what you're model is.
The given statement, "Human movement involves the complex interplay of many body systems." is true. Human movement is a complex process that requires the coordination and interaction of multiple body systems. These body systems include the muscular system, skeletal system, nervous system, and cardiovascular system, among others.
The muscular system plays a vital role in movement by generating force and facilitating the contraction and relaxation of muscles. Muscles work in pairs, with one muscle contracting while the opposing muscle relaxes, allowing for controlled movement. This interplay of muscles is necessary for various movements, such as walking, running, and lifting objects.
The skeletal system provides structural support and serves as the framework for movement. It consists of bones, joints, and connective tissues. Bones act as levers, while joints allow for flexibility and facilitate different types of movement, such as bending, rotating, and extending.
The nervous system is responsible for controlling and coordinating movement. It receives and processes sensory information, sends signals to muscles to initiate movement, and regulates the speed and force of muscle contractions. The brain and spinal cord are integral components of the nervous system, playing a crucial role in coordinating complex movements.
The cardiovascular system, composed of the heart, blood vessels, and blood, transports oxygen and nutrients to the muscles involved in movement. It also carries away waste products, such as carbon dioxide, generated during muscular activity. Adequate blood flow and oxygen supply are essential for optimal movement and performance.

Answer:
pupils
Explanation:
When we step out into bright light, the pupil will contract, reducing the amount of light entering into the eye and protecting our retinas, as well as allowing us to see more clearly. The reason we blink and screw our eyes up in this situation is that this change in pupil size isn't instantaneous.
Answer:
Your pupils
Explanation:
When you all of the sudden go into a bright light, your pupils become smaller to adjust to the brightness. When you go back to a less dark space, your pupils will enlarge.
