What does it mean when muscles contract and how does this process occur in the body?
When muscles contract, they shorten and generate force. This process is controlled by the nervous system, which sends signals to the muscles to release calcium ions. These ions bind to proteins in the muscle cells, causing them to slide past each other and contract. This contraction allows the muscles to produce movement and perform various functions in the body.

What is a body activity that is controlled by involuntary muscles?
One body activity controlled by involuntary muscles is digestion. The smooth muscles lining the gastrointestinal tract contract rhythmically to move food through the digestive system, a process known as peristalsis. These involuntary muscles operate without conscious control, allowing digestion to occur continuously and efficiently. Other examples include the beating of the heart and the regulation of blood vessel diameter.
