What is the largest organ system in the human body?
IntegumentarySystem
It is defined as a self-regulating process by which a living organism can maintain internal stability while adjusting to changing external conditions.
Homeostasis
This organ system is the body's outer protective covering; serves as barrier against infection and injury; helps to regulate body temperature; removes waste product from the body; provides protection against UV radiation; and produces Vitamin D.
Integumentary System
It is a brown pigment that is responsible for the skin color, hair, and eyes.
Melanin
It is a protein that helps form hair, nails and your skin's outer layer (epidermis).
Keratin
This organ system consists of bones, joints, and teeth. It supports and gives shape to the body, and enables the body to move along with the muscular system.
Skeletal System
This organ system consists of three different types of muscles: skeletal muscle; cardiac muscle; and smooth muscle.
Muscular System
This organ system consists of several main organs including the mouth, esophagus, stomach, and small and intestines that form a long tube called gastrointestinal (GI) tract.
Digestive System
This organ system consists of organs that break down food, absorb its nutrients, and expel any remaining waste. Most of its organs make up the gastrointestinal (GI) tract. Food actually passes through these organs.
Digestive System
It refers to the human organ system responsible for the production and fertilization of gametes (sperms or eggs) and carrying of a fetus.
Reproductive System
It is the only human organ system that is significantly different between males and females.
Reproductive System
It is an organ system that brings oxygen into the body and releases carbon dioxide and other waste gases into the atmosphere.
Respiratory System
This organ system includes the brain and spinal cord.
Nervous System
This organ system pumps blood from the heart to the lungs to get oxygen.
Circulatory System
It is the human body system of glands that release hormones into the blood.
Endocrine System
This human body system detects and processes sensory information; it activates bodily responses.
Nervous System
This human body system encloses internal body structures; it is the site of many sensory receptors.

CirculatorySystem
This human body system delivers oxygen and nutrients to tissues; it equalizes temperature in the body.
CirculatorySystem
It is a human organ system that transmits electrical signals throughout the body to coordinate all of the body's voluntary and involuntary activities.
NervousSystem
This human organ system includes the kidneys, ureters, urinary bladder, and urethra and that is responsible for filtering waste products and excess water from the blood and excreting them from the body in urine.
