homeostasis
the maintentce of stable conditions inside your body
4 types of tissues in the body
epithelial, connective, muscular, nervous
epithelial tissue
covers the outside of the body and lines inner surfaces of the body i.e. skin
connective tissue
fills in spaces and connects other tissue together; supports, portects, nourishes an insulates organs i.e. ligaments, catrilage, blood
muscular tissue
contracts and relaxes to allow movement; makes up some organs i.e. diaphragm, biceps, triceps
nervous tissue
transmits messages through your body i.e. brain, spinal cord, nerves
functions of the sketetal system
shape and support
enables movement
protects organs
produces blood cells
stores minerals and other materials
joint
a place in the body where 2 bones come together
ligament
strong, connective tissue that holds bones together
cartilage
a type of connective tissue that covers the end of bones
hinge joint
allows movement forward or backward i.e. knee, elbow
ball-and-socket joint
allows the greatest range of motion i.e. shoulder
pivot joint
allows one bone to rotate around another i.e. neck
gliding joint
allows one bone to slide over another i.e. wrist, ankle
the bones that form the backbone
vertebrae
longest bone in the body
femur
type of muscle found in the heart
cardiac
functions of the digestive system
break down food into molecules that the body can use
absorb he molecules into the bloodstream
eliminate the waste
digestion
the process by which your body breaks down food into small nutrient molecules
absorption
the process by which nutrient molcules pass htrough the wall of your digestive system into your blood
mechanical digestion
foods are physically broken down into smaller pieces; most occurs in the mouth
chemical digestion
chemicals are produces by the body to break down food into smaller chemical building blocks; most occurs in the small intestine
peristlasis
involuntary contractions of smooth muscle that pushes down food
villi
tiny, finger-shaped structures taht absorb nutrients
epiglottis
a flap that prevents food from going down your windpipe
largest organ inside the body
liver
function of the atriums
paccept blood and pump it into the ventricles
function of the ventricles
pump blood out of the heart
pacemaker
a group of heart cells taht send out signals telling other heart cells to contract
arteries
blood vessels that carry blood away from the heart; Arteries=away
veins
carries the blood back to the heart; veINs-into the heart
capillaries
tiny, narrow vessels where the blood from the arteries goes
valve
a flap of tissue that prevents the blood inside the heart from flowing backwards
needed substances get to the body cells
blood
blood types determined
the chemical markers
hypertension
a disorder in which people's blood pressure is consistently higher then others
4 blood components
plasma, red blood cells, white blood cells, platelets
plasma
liquid part of blood
red blood cells
take and deliver oxygen
white blood cells
fight disease
platelets
important fot blood clotting
function of the respiratory system
get oxygen form the outside environment into the inside environment
cellular respiration
carbon dioxide and water are produced
diaphragm
dome shaped muscle that helps you breathe
alveoli
air sacs in the lungs; oxygen passes through a wall of alveolus and then through a capillary wall
function of excretory system
collect waste produced by cells and remove it
nephrons
filtering units of the kidney that remove wastes from the blood and produce urine
urinary bladder
stores urine
glucose in urine
indicates diabetes
