Muscles

Muscles are important for movement and stability in the human body. They are categorized into three types: skeletal, cardiac, and smooth. Skeletal muscles attach to bones and help in voluntary movements. They also help maintain posture and generate heat during activity. Cardiac muscle, which is found only in the heart, contracts continuously to pump blood throughout the body. This muscle type works without conscious effort and is highly durable.

Smooth muscle lines organs like the stomach and blood vessels. It controls involuntary actions, such as digesting food and regulating blood flow by contracting and relaxing. Muscles also play a role in breathing. The diaphragm and intercostal muscles expand and contract the lungs. Muscles contribute to overall metabolism. They burn calories efficiently, even at rest.
