Body Systems & Life NeedsBody Systems

Energy Usage Waste Removal Maintaining Homeostasis

Skeletal n/a n/a Protects vital organs; produces blood cells for transport & protection

Muscular Cellular respiration uses glucose and oxygen for energy

CO2 and lactic acid waste produced

Shivering to keep warm

Respiratory Breathe in O2 for cellular respiration

Removes CO2 and water Breath rate changes depending on activity

Circulatory Transports O2 and glucose to all cells

Transports CO2 to lungs, chemical waste to kidneys and liver

Transports WBCs (infection), nutrients (energy & growth), regulates temperature (blood vessels in skin)

Digestive Digests carbohydrates into glucose for cellular respiration

Removes solid waste (feces)Removes gas waste

Digests & absorbs nutrients for energy, cell processes & growth

Urinary n/a Removes chemical waste from blood and liquid waste from body (urine)

Regulates amount of water and salt in body

Nervous n/a n/a Senses and responds to external and internal conditions

Integumentary

n/a Removes liquid waste (sweat)

Regulates body temperatureBarrier to environment

Diseases & Disorders: Due 1/29/14

For each body system we learned (skeletal, muscular, respiratory, circulatory, digestive, urinary) research TWO disorders for a total of 12 disorders/diseases.

For each… • Name of the disease/disorder• Signs and symptoms• Cause of disorder• Treatment of disorder

Nervous System page due 1/28/14

Overall Functions of the Nervous System• Sense the environment and internal

conditions• Respond to stimuli

Describe Function of Parts of Nervous System• Stimulus• Neuron• Neurotransmitter• Central Nervous System

- Brain- Spinal cord

• Peripheral Nervous System- Autonomic nerves- Voluntary nerves (somatic nerves)

• Sense Organs- Eyes- Ears- Nose- Skin- Tongue

Labelled Sketch of the Nervous System

McDougall, p. B106

Integumentary System page due 1/30/14

Overall Functions of Skin• Repels water (waterproof)• Barrier against infection• Helps maintain homeostasis (temperature, removes

waste)• Senses the environment

Describe Function of Parts Skin• Epidermis• Dermis• Fatty Tissue• Sensor receptor• Nerve• Oil gland• Sweat gland• Hair• Blood vessels

Sketch of Skin

McDougall, p. B84

Osteoporosis What is it?Osteoporosis is a disease that causes bones to become weak which causes them to be more fragile and and break easier. What are the signs & symptoms? Usually people who suffer from osteoporosis experience back pain, loss of bone density, brittle bones, arched posture, or loss of height over time. What causes osteoporosis?A person can acquire if their bones break down faster than the body can produce new bone. Often linked to diets poor in calcium and phosphate.What can treat osteoporosis? Osteoporosis is usually treated with bisphosphonates like Zoledronic Acid or Ibandronate. Patients should consume more calcium (ex. Dairy and green vegetables) and/or take calcium supplements.

Tendinitis (Tendonitis) What is it?Tendinitis happens when your tendons are swollen or irritated. This makes your tendons tender to touch or painful. What are the signs & symptoms? Pain when moving the joint, tenderness, and swelling. What causes tendinitis?Tendinitis can occur if a tendon is moved repeatedly over the course of time stress can also lead to tendinitis What can treat tendinitis?Rest, anti inflammatories, corticosteroids and pain relievers may be used to treat tendinitis however in serious cases surgery may be needed

Influenza (The flu) What is it?Influenza is a virus that attacks your respiratory system What are the signs & symptoms? Fever, chills/sweats, dry cough, and nasal congestion are all symptoms of the flu What causes Influenza?The flu virus which is spread through the air can be inhaled into your body (for example some one sneezing on you) or by touching a object with the virus on it.

GERDGastroesophageal reflux disease What is it?A digestive disease that happens when stomach acid or bile backs up and irritates your esophagus a What are the signs & symptoms? Chest pain, heart burn, dry cough difficulty swallowingWhat causes GERD?GERD happens when you have acid refluxes frequently into the esophagus (heartburn) What can treat GERD?Change diet. Medications like antacids and proton pump inhibitors help the esophagus heal while the limit the acid production or reduce the strength of stomach acid

UTI(urinary tract infection) What are the signs & symptoms? cloudy urine, strong urge to urinate, and leaking urine are all common symptoms for a UTI

What causes UTI?It can be caused by E.coli a bacteria found in the GI(gastrointestinal) can cause a UTI What can treat UTI?Simple infections can be treated in a couple weeks with antibiotics. Cranberry juice can help prevent UTIs
