Bodys transportatory system
4 major functions of the circulatory system
Transport fuel to the body
transport waste to the liver and kidneys to be eliminiated
transport cells to fight off diseases
transport hormones throughout the body
4 major organs of the circulatory system
heart, arteries, veins, capallaries
strongest muscle in the body, muscular pump, cardiac muscle
largest blood vessels carrying oxygenated blood away from heart.
take deoxygenated blood from the body into the heart. Valves directing blood flows
smallest blood cells, carry blood from arteries to body cells to veins. Semipermeable walls allow gases, wastes, nutrients, to exchange between blood and tissues.
cleanses and proccess 1800 quarts of blood every 50 mins.
2 roles: to cleanse the body and regulate body fluid content
shortage or inadequate number of red blood cells.
(caused by not having enought iron in the body)
form of cancer that has an abnormal production of white blood cellls.
disease in which blood is lacking one or more clotting factors (Medicine can help)
hardening of the arteries caused by not eating healthy or lack of exercise.
blood flow to one part of the brain is cut off
High blood pressure
group of passages to exchange gases
Upper Respiratory System
Throat and nose
Lower Respiratory System
Main organ of respiratory system; large shaped cone organs on each side of the heart.
exchange gases between the lungs.
muscles and diaphram contract to inhale and relax to exhale.
upper respiratory infection that affects the nose and throat; lower respiratory infection involves the lungs causing you to cough deeply.
infection of the lungs and causes difficult breathing.
swelling or inflamation on the bronchi
air passages in the bronchial tree swell and constrict
air sacs in the lungs become englarges and loose elasticity
occurs when cells grown out of control and destroy the air sacs in the lungs
framework of the body; provides support and function, act as levers for your muscles.
How many bones do we have?
Layers of bones
Periosteum, Compact, Spongy Bones
produces blood cells and is a place for storage
ligaments, cartilage, joints work together to provide fluid movement.
development of an abnormal curvature of the spine
inflmmation on bursa due to excessive stress on the joint
inflammation of joints
loss of bone tissue/density. Spaces become filled with soft tissue
Effects of Osterioporosis
Lack of good diet, proper excercise contribute to this order, affects most women after menapols, and can affect older men, and calcium supplements and estrogen replacement therapy.
break in a bone
when bone is pushed out of its joint
stretching or tearing of ligaments in a joint
group of tissues making body part move.
How many muscles are there?
Function of Muscles
they work in pairs to shorten or extendl balancing act
Three types of muscles
Cardiac, smooth (inside organs), skeletal
You control movement
You dont control movement
caused by overworking a muscle or group of muscles.
results when the muscle cannot relax caused by an electrolyte imbalance.
blood vessels are broken in the area; caused by indirect blow.
muscle overused or muscle improperly warmed up and stretched prior to physical activity can cause muscle to tear in the belly or pull away from the bone.
defined as the organs that take in and break down food into a chemical form that can be absorbed by the body.
process in which food is broken down.
long muscular canal ( 30 ft) that connects the mouth to the anus.
Located in the mouth (Beginning of digestion).. Saliva is 99% water, it moistens food and mouth, keeps mouth clean from bacteria, and keeps mouth moist so we can speak.
4 Primary tastes
Sour, Sweet, Salty, Bitter
pear shaped sac lies underneath the liver, stores bile produced by liver.
breaks down fat in diet
largest inner organ of the body, important organ in body, lies below the diaphram, produces bile.
Deals with sugar and insulin balance
connected to the stomach, 18-23 ft in length, 1-1.5 inches wide. Function: absorbs the nutrients into the blood stream via millions of little villi which grab absorbable nutrients.
caused by over eating, eating too fast, happens when stoamach acid comes back into the esophagus and your cardiac sphincter doesnt close properly.
happens when in the small intestine or stomach has an open sore on the membrane lining.
formed when the bile stored in the gallbladder hardens into small crystals, can block the flow of bile and cause pain.. the treatment is removal of the gall bladder.
where enough of the liver cells have been damaged or destroyed that the liver can no longer function right
purpose is to provide ways for your body to excrete waste
Causes of Food Poisioning
Bulges in the cans, food that isnt refrigerated, food that odors or has discoloration, foods not cooked throughly
begins in the lower right side of abdomen. main function is to excrete waste. Parts: cecum, colon, rectum, anal canal. First half absorbs liquids and second half is storage/excretes waste.
poor diet and exercise, lack of water, ignoring urge to purge, contribute to feces (waste) to become dry and immobile.
too much water in the bowels causing loose feces passed often.
calcium stones inside kidney that can be passed in urine or cant be passed at all
Urinary tract infection
caused by bladder infection, pain while peeing, back pain.
colon cancer on the rise
skin, nails, hair, sweat glands, oil glands.
3 functions of Skin
protection, regulation of body temperature, sensitivity
caused by virus, harmless until bothersome ( if changing color or shape, call doctor and get them removed)
Colluses and Corns
buildup of skin caused by pressure of friction on feet.
usually caused by herpes simplex 1 virus.
Basal cell carcinoma
skin cancer.. most common least dangerous
Squamous cell carinoma
skin cancer... more serious and commonly metasizes
works with Lymphatic system to help fight off infection
Ability to fight off a normal cold without medicine from a doctor.
uses medicine/shots to help fight off diseases.. gives the body the ability to recognize certain intruders and become resistance to them.
B and T cells each with their own function.
result of the body's failure to fight off infection or tumors
can take advantage of a weakend immune system and cause more sever symptoms than they would normally
what does AIDS mean?
Acquired Immunodeficiency Syndrome
your immune system mistakes it own cells for infections and start fighting itself
Central Nervous System
made up of the brain and spinal cord, purpose to maintain homeosatis
Periphal Nervous System
made up of perpheral nerves stemming from the spinal cord
Somatic Nervous System
ability to sense and respond to things from the outside environment.
Autonomic Nervous System
controls internal involuntary environment
caused by injury when part of the spine is displaced and pinches or squeezes a nerve.
brain disorder caused by sudden burst of activity
the cerebrum of the brain is damaged causing muscle spasms, poor balance.
outer coating of the nerves is destroyed therefore the person loses control over some parts over the body
Secrete hormones to send messages to cells in the body.
Function: energy control, sugar and insulin balance, water and salt balance, human growth can causes dramatic emotions.
releases growth hormones, too much or too little effects how much a person grows
Little hormones produced
Too much hormones produced
body cannot properly utilized glucose, the disorder is in the release of insulin or lack of insulin.
produces seminal fluid that is added to sperm to make semen
