BMS 300 Exam 3 Questions With Correct
Answers
diffusion limits - ANSWER✔✔✔-distance from oxygen or nutrition
| | | | | | | |
source
arteries - ANSWER✔✔✔-lead away from the heart (ox)
| | | | | | |
veins - ANSWER✔✔✔-carry blood to the heart (deox); return vessels
| | | | | | | | |
capillaries - ANSWER✔✔✔-where oxygen, carbon dioxide, nutrients and
| | | | | | |
metabolites are exchanged; cap bed=exchange tubes
| | | | | |
fish cardiovascular system: atrium - ANSWER✔✔✔-recieves blood from
| | | | | | | |
the systematic vasculature; sends deox blood to the gills
| | | | | | | |
fish cardiovascular system: ventrical - ANSWER✔✔✔-pumps blood to
| | | | | | | |
the gill and the system vascular
| | | | |
fish cardiovascular system: gill structure - ANSWER✔✔✔-erythrocyte;
| | | | | | |
endothelia cell; blood vessel
| | |
,fish cardiovascular system: gill capillaries - ANSWER✔✔✔-drawn
| | | | | | |
together to form vesicles that deliver oxygen rich blood to the tissues
| | | | | | | | | | |
order of the mammalian heart - ANSWER✔✔✔-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? - ANSWER✔✔✔-closed
| | | | | | | | |
endothelia cells - ANSWER✔✔✔-cells of the pulmonary capillaries;
| | | | | | | |
continuous layer within | |
pericardium - ANSWER✔✔✔-coninuous outer layer of mesothelial cells;
| | | | | | |
attached to body wall; attached to basil lamina
| | | | | | | |
contraction left side - ANSWER✔✔✔-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 - ANSWER✔✔✔-period of ventricular filling (atrial contraction,
| | | | | | | |
isovolumetric ventricular relaxation) | |
isometric relaxation - ANSWER✔✔✔-short 30-60 seconds; sarcomeres
| | | | | | |
smaller
cardia output - ANSWER✔✔✔-4.3 L/min
| | | |
ejection phase - ANSWER✔✔✔-blood leaves the ventricle across the
| | | | | | | | |
aortic valve |
afterload - ANSWER✔✔✔-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 - ANSWER✔✔✔-diastole;
| | |
artial myocardium contraction;
| |
ventricular myocardium contraction; | |
, period of isometric contraction; afterload;
| | | |
ejection;
isovolumetric relaxation |
blood supply to the myocardium - ANSWER✔✔✔-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 - ANSWER✔✔✔-uninuclear and branched
| | | | | |
cardiomyocyte: desmosomes - ANSWER✔✔✔-desmosomes | | | |
(mechanically linked); |
gap junction ( link by electrical synapse);
| | | | | |
cytoplasmic (protein plaque); | |
cadherons
cardiomyocyte: Dihydropurine receptor - ANSWER✔✔✔-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 - ANSWER✔✔✔-deliver action potentials to | | | | | |
the contractile cardiomyocytes
| | |
