BIOS 255 Comprehensive Exam Study
Questions and Answers 2025
Stroke Volume (SV) -Answers- EDV-ESV
Cardiac Output (CO) -Answers- SV x HR
Pulse Pressure (PP) -Answers- SBP-DBP
Mean Arterial Pressure (MAP) -Answers- diastolic pressure + pulse pressure/3
What is the QRS complex of an ECG? -Answers- ventricular depolarization
endocrine cells -Answers- release their secretions directly into body fluids
exocrine glands -Answers- secrete chemical substances into ducts that lead either to
other organs or out of the body
nerve that innervates the diaphragm -Answers- phrenic nerve
Synergist -Answers- muscle that aids the prime mover
precentral gyrus -Answers- primary motor cortex
osteoclasts function -Answers- resorption, breakdown of bone matrix
Osteoblasts -Answers- bone forming cells
Agglutination -Answers- clumping of red blood cells
pulmonary valve -Answers- This valve is located between the right ventricle and the
pulmonary artery. It stops blood from flowing backward into the right ventricle.
aortic valve -Answers- The semilunar valve separating the aorta from the left ventricle
that prevents blood from flowing back into the left ventricle.
blood colloid osmotic pressure -Answers- The largest driving force for pulling fluid from
the interstitial spaces back into the capillaries is
muscles of the hamstrings -Answers- biceps femoris, semitendinosus,
semimembranosus
Diaphysis -Answers- shaft of a long bone
