Body components refer to the various parts that make up a living organism. In humans, these include organs like the heart, lungs, and liver, which perform essential functions for survival. Additionally, body components encompass tissues, such as muscle and nervous tissue, that work together to support movement and communication within the body. Another important aspect of body components is the skeletal system, which provides structure and protection for vital organs. The circulatory system, consisting of the blood and blood vessels, transports nutrients and oxygen throughout the body. Together, these components ensure the body operates efficiently and maintains overall health.
