Cards

Term
erythrocytes
Definition
red blood cells-transport oxygen and CO2 to and from tissues
Term
leukocytes
Definition
white blood cells-nucleated
granulocytes and agranulocytes
named on how they stain
Term
granulocytes
Definition
leukocytes that contain membrane bound granules
Term
neutrophils
Definition
type of granulocyte that stains deeply and has many lobes
cytoplasm does not stain
destroys bacteria
Term
eosinophils
Definition
type of granulocyte
two darkly stained lobes connected by a thin strand
large granules that stain red/orange
these phagocytize antigens and attack some worms
Term
basophils
Definition
granulocyte
has two lobes that are hard to see b/c of large stained granules
aid in inflammation with release of histamine
Term
agranulocytes
Definition
leukocytes that lack membrane bound granules
Term
lymphocytes
Definition
agranulocyte
round nucleus that fills most of cytoplasm (dark blue to purple)
specific disease resistant (T and B cells)
Term
monocytes
Definition
agranulocyte
kidney shaped with smaller nucleus
develop into macrophages
Term
precava/postcava
Definition
two large veins that enter the right atrium and has unoxygenated blood from superior and inferior body respectively
Term
right atrium
Definition
first chamber of the heart
receives unoxygenated blood from body
Term
tricuspid valve
Definition
separates the right atrium and ventricle
Term
right ventricle
Definition
second chamber of heart
pumps blood to lungs
Term
pulmonary semilunar valve
Definition
valve separates pulmonary trunk from right ventricle
Term
pulmonary arteries
Definition
these arteries carry unoxygenated blood from right ventricle to lungs
Term
pulmonary veins
Definition
carry unoxygenated blood from lungs to left atrium
Term
left atrium
Definition
third chamber of heart that receives oxygenated blood from lungs
Term
bicuspid valve
Definition
separates the left atrium and ventricle
Term
left ventricle
Definition
fourth chamber of heart
receives oxygenated blood from left atrium and pumps to body
Term
aortic semilunar valve
Definition
separates aortic arch from left ventricle
Term
aortic arch and aorta
Definition
largest elastic artery in body
carries oxygenated blood to body
Term
chordae tendonae and papillary muscles
Definition
muscles that control the tricuspid and bicuspid valve
Term
coronary arteries and veins
Definition
vessels located on and in the myocardium of heart. supplies blood to myocardium
