Human Body Systems Overview

Flashcards covering key concepts related to the human body systems.

Skeletal System

Composed of bones, cartilage, ligaments, and tendons; supports the body, protects internal organs, allows movement, stores minerals, and produces blood cells.

Integumentary System

Includes skin, hair, nails, sweat glands, and oil glands; guards against infection and injury, helps regulate body temperature.

Muscular System

Contains skeletal muscle, smooth muscle, and cardiac muscle; produces movement and helps circulate blood and food through the digestive system.

Circulatory System

Consists of the heart and blood vessels; transports oxygen, nutrients, and waste, fights infection, and regulates body temperature.

Respiratory System

Made up of the nose, pharynx, larynx, trachea, bronchi, and lungs; brings in oxygen and removes carbon dioxide.

Digestive System

Consists of the mouth, esophagus, stomach, small intestine, liver, pancreas, large intestine, and rectum; breaks down food, absorbs nutrients, and removes waste.

Excretory System

Consists of skin, lungs, liver, kidneys, urinary bladder, and urethra; removes waste products from the body.

Nervous System

Composed of the brain, spinal cord, and nerves; controls the body's responses to internal and external changes.

Endocrine System

Includes glands such as the thyroid, pancreas, adrenals, ovaries, and testes; controls growth, development, energy processes, and maintains homeostasis.

Reproductive System

In males includes testes, ducts, urethra, and penis; in females includes ovaries, ducts, uterus, and vagina; produces sex cells and nurtures developing embryos.

Immune System

Consists of lymph nodes, lymph vessels, and white blood cells; fights infections and attacks invading bacteria and viruses.
