Overview of the 11 Organ Systems

These flashcards cover the key concepts of the 11 organ systems, highlighting their functions and components.

Integumentary System

The organ system that includes the skin, hair, and nails; responsible for protection, temperature regulation, sensation, and vitamin D synthesis.

Skeletal System

The organ system composed of bones and joints; provides structural support, protects organs, produces blood cells, and stores minerals.

Muscular System

The organ system primarily consisting of skeletal muscles responsible for movement, posture, and heat production.

Nervous System

The organ system that includes the brain, spinal cord, and nerves; responsible for fast communication and control, sensory processing, and coordination of body functions.

Endocrine System

The organ system that regulates body functions through hormones; communicates more slowly than the nervous system.

Cardiovascular System

The organ system that transports blood, nutrients, gases, and waste throughout the body; includes the heart and blood vessels.

Lymphatic System

The organ system that helps with fluid balance, absorbs lipids from the digestive tract, and is integral to the immune response.

Respiratory System

The organ system responsible for gas exchange, bringing oxygen into the bloodstream and expelling carbon dioxide.

Digestive System

The organ system that processes food, absorbs nutrients, and eliminates waste; includes the mouth, esophagus, stomach, intestines, liver, and pancreas.

Urinary System

The organ system that removes waste from the blood and regulates water, electrolytes, and pH; includes the kidneys, ureters, bladder, and urethra.

Reproductive System

The organ systems that produce and transport gametes; includes the male (testes, vas deferens) and female (ovaries, uterus) reproductive organs.
