The Organ Systems of the Human Body

The human body is made up of 11 organ systems. The Integumentary System, Skeletal System, Muscular System, Nervous System, Endocrine System, Circulatory System, Lymphatic System, Respiratory System, Urinary System, Digestive System, and Reproductive System for the male and female. Also, we have the Immune System which is an accumulation of cells rather than an organ system.

Protection, support and movement are the main functions of the Integumentary system, Skeletal system, and Muscular system. The Integumentary system is made up of skin, hair, nails, and the coetaneous glands. The functions of this system include protection, water retention, thermoregulation, vitamin sensation, and nonverbal communication. Then there is the Skeletal system made up of bones, cartilages, and ligaments. The functions of the skeletal system include support, movement, and protective enclosure of viscera, blood formation, electrolyte and acid base balance. The Muscular system is also included in the protection support and movement systems of the body. The Muscular system is made of skeletal muscles. The functions of the skeletal system include movement, stability, communication, control of body opening, and heat production.

Internal communication and integration are the main functions of the Nervous system and Endocrine system. The Nervous system is made up of the brain, spinal cord, nerves and ganglia. The functions of the Nervous system include rapid internal communication, coordination, motor control and sensation. The Endocrine systems organs are the pituitary gland, pineal gland, thyroid gland, parathyroid glands, thymus, adrenal glands, pancreas, testes and ovaries.
