Etymology

The term "largest body part" is derived from the English words "large" meaning big in size, and "body part" referring to a portion of the human body.

Skin

The skin is the largest organ by surface area in the human body. It serves as the body's primary line of defense against pathogens and harmful substances. The skin also plays a crucial role in thermoregulation, sensation, and vitamin D synthesis.

Muscular System

The muscular system is the largest body part by volume. It is composed of skeletal muscle, cardiac muscle, and smooth muscle. The muscular system is responsible for movement, maintaining posture, and generating heat.
