Practical 1 Flashcards
erythrocytes
red blood cells: picks up oxygen from lungs and delivers elsewhere
neutrophil
granulocytes: most abundant WBC: releases antimicrobial chemicals
eosinophil
granulocytes: reddish pink: release enzymes that weaken/destroy parasites
basophil
granulocytes: secrete histamine, increasing blood flow to a tissue
lymphocyte
agranulocytes: secrete antibodies, destroy cancer cells
monocyte-
agranulocytes: phagocytize pathogens
pericardial sac
outer wall- tough superficial fibrous layer of dense irregular connective tissue
epicardium
serous membrane of the external heart surface
endocardium
lines interior of heart chamber
myocardium
between the two- composed of cardiac muscle. thickest layer
apex
bottome left lower end
left and right atria
2 superior chambers, receiving chambers for blood returning to the heart by great veins
auricles
ear like flap. pumps blood into the ventricles. each atrium has one
left and right ventricle
2 inferior chambers. pumps that eject blood into the arteries and keeps it flowing around the body
coronary sulcus
encircles the heart near the base and separates the atria anove the ventricles below
interatrial septum
septum that separates the atria
interventricular septum
thick muscle wall that separates the ventricles
tricuspid valve
right AV valve (3 cusps)
bicuspid valve
left AV valve -2 cusps.(separates left and right
chordae tendineae
connects to the papillary muscles
papillary muscles
governs the timing of electrical excitation of the papillary muscles
pulmonary semilunar valve
controls the opening from the right ventricle into the pulmonary trunk
aortic semilunar valve
valve the separates the left ventricle and the aorta
fossa ovalis
artifact from when the fetus received blood from the mother
aorta
largest artery carrying blood (oxygenated) away from the heart
pulmonary trunk (and arteries)
arteries carrying blood (deoxygenated) to the lungs
pulmonary veins
veins carrying blood (oxygenated) from the lungs to the heart to be pumped
inferior vena cava
one of 2 major veins taking blood (deoxygenated into the heart)
superior vena cava
one of 2 major veins taking blood (deoxygenated) into the heart.
superior vena cava
largest vein, feeding into the right atrium. superior to the heart
inferior vena cava
largest vein, feeding into the right atrium, inferior to the heart
azygos vein
vein taking blood from the posterior wall of the thorax and abdomen, feeds into the Superior Vena Cava
l/r brachiocephalic veins
veins returning from the jugular and arms
l/r internal jugular veins
veins returning from the face and brain (flap, very squishy)
l/r subclavian veins
veins returning from the arms and meets into the BC veins
posterior intercostal veins
veins returning blood from the outer edge of the rib cage. meets in the azygos veins
axillary vein
vein returning blood from the cephalic and basilic veins
brachial vein
vein running between the brachial and cephalic veins
cephalic vein
vein running on the inside of the arm. runs into the axillary vein
median cubital vein
vein running between the cephalic and basilic vein right around the elbow
ulnar vein
vein running into the brachial vein on the pinky side, underneath the arm.
radial vein
vein running into the brachial vein, on the thumb side
