six systems Flashcards
skeletal system
gives our bodies structure and protects major organs
muscular system
enables movement of the body and internal organs
nervous system
sends signals between different parts of the body and brain
digestive system
absorbs nutrients from food and digests and turns food into waste
respiratory system
takes in oxygen and releases carbon dioxide
red blood cells
carry oxygen
white blood cells
fight infection and disease (WHITE/FIGHT)
platelets
blood clotting
plasma
carries nutrients throughout blood system
skeletal muscle (voluntary)
muscles attached to bone that cause body movements
cardiac muscle (involuntary)
muscle that forms the walls of the heart
smooth muscle (involuntary)
acts on lining of the body’s passageways and hollow internal organs
voluntary
movements you can control
involuntary
movements you can’t control
function of the nerve cells
to carry electrical signals from one part of the body to another
unicellular
a single celled organism
multicellular
consisting of many cells
step 1 of the healing process
PLATELETS travel to the injured site to clot blood
step 2 of the healing process
WHITE BLOOD CELLS travel to the area to fight infection
step 3 of the healing process
skin cells DUPLICATE chromosomes
step 4 of the healing process
skin cells SPLIT to create NEW CELLS
AUTOtroph
an organism that MAKES its own food
HETEROtroph
an organism that must CONSUME food
function of the brain
control center for the entire nervous system
function of the brain
