Anatomy 1 Lecture 2 : Overview of Organ Systems I. Major Organ Systems A. There are 12 major organ systems of the body: 1. integumentary (skin) 2. skeletal (bone) 3. muscular (muscles) 4. nervous (CNS and PNS) 5. endocrine (hormones/regulation) 6. cardiovascular (heart and blood vessels) 7. lymphatic (lymph fluid) 8. respiratory (lungs) 9. digestive (stomach, intestine) 10. urinary (kidneys, bladder) 11. reproductive (male and female genitalia) 12. immune (cells in the blood/body) II. Integumentary System A. Major Components 1. skin (epidermis, dermis, etc.) 2. hair 3. sweat and oil glands 4. sensory organs and glands B. Major Functions 1. helps to regulate body temperature 2. protects against external injury and desiccation 3. eliminates salts and urea 4. produces vitamin D 5. responds to temperature, pressure, and pain III. Skeletal System A. Major Components 1. bone 2. cartilages

Major Functions 1. provide protection for internal organs (skull, ribs) 2. provide support for body 3. mechanical advantage for muscular actions (levers) 4. storage of vital minerals - calcium 5. site of blood cell formation (marrow) IV. Muscular System A. Major Components 1. muscles of different type/function a. striated muscle (voluntary) b. smooth muscle (involuntary) c. cardiac muscle (heart) B. Major Functions 1. striated muscle a. primarily to contract on command b. allows voluntary motions such as walking, grasping, and moving in general, facial expressions 2. smooth muscle a. contracts to allow involuntary motion b. along arteries, digestive tract 3. cardiac muscle a. contracts in rhythmic fashion involuntarily b. propels blood through lungs and body 2...
