**Endocrine System**: Secretes hormones, regulates body’s response to stress. Blood delivers hormones to all cells. **Major structures**: Pituitary gland, adrenal gland, thyroid gland, liver and kidneys. **Diseases**: glucagonoma and graves disease (thyroid is over active)
 * The 11 Systems of the Body: **

**Nervous System**: detects stimuli in body, analyzes and stores information, responds to your choices. **Diseases**: multiple sclerosis, Parkinson’s, epilepsy. **Major structures:** brain, spinal cord and sensory organs.

**Urinary System**: body takes nutrients from food and eliminates the rest as waste. **Major structures:** kidney, ureter, sphinder, bladder and urethra. **Diseases:** Urinary tract infection, cystitis (bruising of the bladder)

**Respiratory System:** Gas exchange regulates blood Ph. **Major Organs**: pharynx and larynx, trachea, lungs, bronchi, bronchioli. **Diseases**: Whopping cough, and COPD (chronic obstructive pulmonary disease) (lungs are irritated)

**Integumentary System**: excretes waste, protection from external environment, regulates your temperature. **Major** **structures**: dermis, epidermis, sweat glands, hair shaft, melanin and Keratin **Diseases:** skin cancer and acne

**Cardiovascular System**: Transports substances to and from the body cells, and pumps blood throughout the body. **Major structures:** heart, lungs, blood, and blood vessels. **Diseases:** coronary artery disease (plaque buildup in arteries) heart valve disease (the heart valve doesn’t open r close tightly)

**Digestive System:** Turns food into energy that you need to survive and stores waste for removal from the body. **Major structures**: mouth, esophagus, stomach, small intestine, pancreas, liver, colon, and large intestine. **Diseases**: Appendicitis and crones disease. **Image:** http://www.medicalook.com/systems_images/Digestive_System_large.jpg

**Skeletal System**: Support, protection, assistance with movement, mineral homeostasis, produces red blood cells, attachment for muscles. **Major structures**: skull, patella, and femur. **Diseases**: scoliosis, osteoperosis (depletion of calcium) and arthritis (damages your joints). **Image:** http://danceguadagno.wikispaces.com/file/view/Skeletal_System.gif/241145923/Skeletal_System.gif **Muscular System**: Movement, reaction to stimuli, protects organs, produces body movement, pumps blood to the body and digests food. **Major structures:** cardiac muscle and skeletal muscles. **Diseases**: fibromyalgia (pains in your muscles, joints and tendons) and ALS (aka Lou Gehrig’s disease) attacks your motor neurons and causes weakness in your arms and legs. **Image:** http://www.medicalook.com/systems_images/Muscular_System.jpg

**Reproductive System:** Produces offspring. **Major Structures:** ovaries and testes. **Diseases**: ovarian and testicular cancer.

**Lymphatic System:** Removes and destroys waste debris dead blood cells, pathogens, toxins and cancer cells. It also absorbs fats and fat-soluble vitamins and removes excess fluid. **Major Structures**: spleen, thymus gland, lymph nodes and lymph vessels. **Diseases**: Lymphadenopathy (swelling of lymph nodes).
