BMS 300 FINAL EXAM Questions with 100%
verified Answers Latest Updates 2024
diffusion limits correct answers distance from oxygen or nutrition source
arteries correct answers lead away from the heart (ox)
veins correct answers carry blood to the heart (deox); return vessels
capillaries correct answers where oxygen, carbon dioxide, nutrients and metabolites are
exchanged; cap bed=exchange tubes
fish cardiovascular system: atrium correct answers recieves blood from the systematic
vasculature; sends deox blood to the gills
fish cardiovascular system: ventrical correct answers pumps blood to the gill and the system
vascular
fish cardiovascular system: gill structure correct answers erythrocyte; endothelia cell; blood
vessel
fish cardiovascular system: gill capillaries correct answers drawn together to form vesicles that
deliver oxygen rich blood to the tissues
order of the mammalian heart correct answers oxygen poor blood get pumped through inferior
and superior vena cava, then into RA, through tricuspid valve or R. atrioventricular valve into the
RV and out through the pulmonary valve into the pulmonary artery to lungs, from lungs oxygen
rich blood enters the heart through the pulmonary vein into the LA; then goes through bicuspid
valve or L. atrioventricular valve into the LV and out of the heart through the aorta valve into the
aorta to carry oxygen rich blood to tissues
what kind of system is the mammalian heart? correct answers closed
endothelia cells correct answers cells of the pulmonary capillaries; continuous layer within
pericardium correct answers coninuous outer layer of mesothelial cells; attached to body wall;
attached to basil lamina
contraction left side correct answers contraction of the atremyocardium; contraction of the
ventricular myocardium; cant change volume of heart, pressure increases, force generated on the
blood in the ventricle; as ventricle contracts, AV valve shuts and aorta valve open; muscle more
thick than right side; low pressure return from lungs
diastole correct answers period of ventricular filling (atrial contraction, isovolumetric ventricular
relaxation)
, isometric relaxation correct answers short 30-60 seconds; sarcomeres smaller
cardia output correct answers 4.3 L/min
ejection phase correct answers blood leaves the ventricle across the aortic valve
afterload correct answers pressure on the ventricular myocardium after a contraction begins
For the left ventricle, pressure in the aorta during ventricular ejection determines the afterload.
Afterload ^ mean arterial pressure )
cardiac cycle correct answers diastole;
artial myocardium contraction;
ventricular myocardium contraction;
period of isometric contraction; afterload;
ejection;
isovolumetric relaxation
blood supply to the myocardium correct answers through the coronary arteries-> arterioles->
capillaries (exchange bed) -> coronary sinus -> right atrium; require a capillary bed to deliver
oxygen and nutrients; blood flow to the myocardial capillary beds occurs during distaole
structure of cardiomyocyte correct answers uninuclear and branched
cardiomyocyte: desmosomes correct answers desmosomes (mechanically linked);
gap junction ( link by electrical synapse);
cytoplasmic (protein plaque);
cadherons
cardiomyocyte: Dihydropurine receptor correct answers v-g calcium channel; sense positive
charge and the gate opens; allows calcium in ( calcium induced, causes the RYR to open..
Calcium released)
cardiomyocytes: conductile correct answers deliver action potentials to the contractile
cardiomyocytes
cardiomyocytes: contractile correct answers generates forces; contracts; 98% of CMC in heart;
calcium binds to troponin C... calcium induced, calcium released
sinoarticle vessle correct answers cluster of contractile CMC, pacemaker
sinalatrial node (SA) and atrioventricular node correct answers collection of conductile CMC
flow of conductile CMC correct answers sinoatrial node
AV node
bundle of his
