Answer 1

The muscular system helps humans maintain posture by constantly contracting to work against gravity and support the spine and legs.

Step-by-step explanation:

The muscular system plays a crucial role in helping humans maintain posture. Muscles constantly contract to work against the force of gravity and keep the body upright. For example, the muscles in your back and abdomen help support your spine and keep it aligned correctly. Additionally, the muscles in your legs help maintain balance and stability. When these muscles contract, they create tension in your tendons and enable you to stand and move with proper posture.
