what are the two upper chambers of your heart called
atriums
what is hypertension
high blood pressure
where is hemoglobin found
in the red blood cell
what is the function of hemoglogin
it is a chemical in read blood cells that carries oxygen to tissues
what is the difference in the shapes of the red and white cells
the red cells are a disc shape
white cells are round
what is the largest artery in the body
aorta
what do white blood cells do
they fight off infection
what is it called when arteries get glogged
artherosclerosis
in the circulatory system there are thick vessels that carry bloodaway from the heart what are they called
arteries
in the circulatory system there are elastic vessels that carry blood back to the heart what are they called
veins
two purposes of the respiratory system
supply oxygen to the blood

remove carbon dioxide
a byproduct of respiration is
carbon dioxide
vocal cords or voicebox
larynx
dome shaped muscle at the bottom of the chest which helps with breathing
diaphram
two brached out passageways which go from the trachea to the lungs
bronchi`
process in cells where oxygen combines with food to produce oxygen
respiration
passageway at the back of the nose and mouth
pharynx
tube which tramsports air to the lungs
trachea
main organ of respiration where o2 + co2
is exchanged
lungs
flap of tissue that covers trachea when swallowing
epiglottis
these air sacs are located at the very end ofthe bronchi- they are round sacs and have thin walls- this is where oxygen and carbon dioxide is exchanged from the respiratory system into the blood
alveoli
what do platelets do to the blood
they clot(thicken) the blood
three parts of the circulatory system
blood, blood vessels and heart
shape of red cells
disk shape- round
shape of white cells
irregular
in a plant - a disk like structure in the plant cell that contains chlorophyl
chloroplast
rod shaped bodies in a cell that store and release energy
mitochondria
a thin layor of protein that surrounds a cell- lets material in and out of cell
cell membrane
a rigid layer that currounds a plant cell
cell wall
is center of cell and controls all life activities of the cell
nucleus
a liquid filled sac in a cell(storage sac)
vacuole
one celled organ
unicellular
many celled organ
multicellular
a network of tubelike structure in a cell
endoplasmic reticulum
this organelle in the cell makes protein
ribosome
the process which a cell divides into two cells and divides aagain
mitosis
what is the cell theory
every cell comes fromanother cell all organisms are made up of cells
what connects the mouth to the stomach
esophagus
the stomach breaks down this nutrient
protein
nutrient made of sugar or starch
carbohydrates
mineral that helps build strong bones and teeth
calcium
which intestine absorbs water and passes undigested food through as waste
large intestine
where does digestion
mouth
what is in the mouth that begins to break down the food
teeth - mechanical

enzymes in saliva - chemical
function of digestive system
to change food so it can be used by the body for energy
what begins chemical digestion
saliva in the mouth
what begins mechanical digestion
chewing with teeth in the mouth
what are carbohydrates made of
sugar and starch
examples of carbohydrates
vegetables, sweets, most white foods - bread, potatoes
what do carbohydrates give give to the body
they give off energy and heat
what do proteins give to the body
build and repair body tissue
protein examples
meats, fish nuts, beans, cheese
what do fats do for your body
store energy for later use
fat examples
oils, butter, fat from meats
what is necessary for all cells to carry out life functions but does not give off energy
water
what is the measurement of eneergy from food
calories
the study of heredity
genetics
what is gene theory
one half of the genes come from the sex cell of one parent

one half of the genes come from the sex cell of the other parent
genes can be dominant or recessive

which one always shows itself is represented by capitalletter
dominant
what kind of gene stays hidden when the dominant gene is present
recessive - shown by a lower case letter
in chemistry this contains 2 or more atoms
molecule
what is called the diffusion of water through a cell membrane
osmosis
physical change
when matter changes it's appearance
a tissue that is used to move all parts of the body

made up of individual cells called fibers
muscle
functions of muscle
produce movement

give us strength

aid in movement of food during digestion

to help move blood through body

to help in removal of body wastes
how do muscles work
effort force (force from humans)- use energy to move body by making humans work
what is is called when movement is controlled by our thoughts
voluntary (you can control it by thinking of what you want it to do)
what is it called when movement is automatically controlled by the brain
involuntary - the brain makes the movements not your thoughts
three types of muscles
skeletal
cardiac
smooth
where do you find skeletal muscle
attached to bones - help you walk, talk, run
where is cardia muscle found
heart - contracts to pump blood
where is smooth muscle found
in the walls of many interanal organs
describe cartilage
Cartilage is a translucent, elastic tissue (bluish) found at end of bone provides padding
