Human body labeled diagram game quiz online
To put it mildly, the human body is a complex structure. It is primarily composed of living cells, which work together to form tissues, organs, and organ systems. Studying the structure of the human body is a field unto itself – a science called anatomy.
The human body can be separated into several different organ systems, each responsible for performing specialized roles and sustaining life.
The integumentary system, made of the skin, is our body’s largest organ. The skin acts as a protective sheath against harmful microorganisms, heat and other environmental hazards.
The body’s muscular system is divided into skeletal muscles, which enable movement; cardiac muscles, which work to pump blood in the heart; and smooth muscles, which perform involuntary processes like digestion.
Skeletal muscles are attached to the bones of the skeletal system. Our skeleton provides a sturdy framework for the body, protects our delicate insides, and produces various blood cells.
Other systems include the digestive system, which absorbs and converts food into energy and building material; the circulatory system, which works with the respiratory system to provide oxygen for cellular activities; the immune and lymphatic systems, which protect against harmful particles; and the reproductive system, which ensures the continued survival of the human race.
Lastly, the nervous system controls all of the aforementioned processes, ensuring that all processes contribute to homeostasis and continued living.
This human body labeled diagram is a useful resource to better visualize the divisions within the human body and relate them to the body’s various processes.
