BMS 300 exam 3 2024 (A+ GRADED)

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
