Define the Skeletal System, its functions and what it is composed of
Provides support and protection, site of hemopoiesis, stores calcium and phosphorus , provides sites for muscle attachmenets
Integumentary system
Provides protection, regulates body temperature, site of cutaneous receptors, synthesizes vit. D, prevents water loss
Muscular System
Produces body movement, generates heat when body moves
Endocrine System
Consists of glands and cell clusters that secrete hormones, some of which regulate body and cellular growth, chemical levels in the body, and reproductive functions.
Nervous System
A regulatory system that controls body movement, responds to sensory stimuli, and helps control all other systems of the body. Also responsible for consciousness, intelligence, memory.
Cardiovascular System
Consists of the heart, blood, and blood vessels; the heart moves blood through blood vessels in order to distribute hormones, nutrients, and gases, and pick up waste products.
Respiratory System
Responsible for exchange of gases between blood and the air in the lungs.
Lymphatic System
Transports and filters lymph (interstitial fluid transported through lymph vessels) and initiates an immune response when necessary.
Digestive System
Mechanically and chemically digest food materials, absorbs nutrients, and expels waste products.
Male Reproductive System
Produces male sex cells (sperm) and male hormones ( e.g., testosterone), transfers sperm to the female.
Urinary System
Filters the blood and removes waste products from the blood, concentrates waste products in the form of urine, and expels urine from the body.
Female Reproductive System
Produces female sex cells (oocytes) and female hormones (e.g., estrogen and progesterone), receives sperm from male, site of fertilization of oocyte, site of growth and development of embryo and fetus.
