BIOS 255 COMPREHENSIVE EXAM 2026 UPDATE
QUESTIONS AND CORRECT VERIFIED ANSWERS
ALREADY GRADED A+ (BRAND NEW VISION)
Oh Once One Takes The Anatomy Final Very Good Vacations Are Happening - ANS-Olfactory,
Optic, Oculomotor,Trochlear, Trigeminal,Abducens,Facial, Vestibulocochlear,
Glossopharyngeal, Vagus,Accessory, Hypoglossal
parasympathetic nervous system effects - ANS-slow HR, little to no effect on contractility, vagal
tones
sympathetic nervous system effects - ANS-pupils dilate, heart rate increases, airways dilate,
urinary function decreases, blood flow, oxygen, glucose to the skeletal muscle increases
Path of light through the eye - ANS-cornea, aqueous humor, pupil, lens, vitreous humor, retina
What are endocrine glands? - ANS-ductless glands that produce hormones
examples: pituitary, thyroid, parathyroid, adrenal, and pineal glands
What are exocrine glands? - ANS-glands that secrete their products into ducts that open onto
surfaces
examples: sweat, tears, saliva, milk, and digestive juices
function of antidiuretic hormones - ANS-promotes retention of water by kidneys
, What is hematocrit? - ANS-The percentage of blood volume taken up by RBCs
How can hematocrit increase? - ANS-
Agglutination - ANS-clumping of red blood cells; will result if blood types with different
antigens are mixed
blood typing interpretation - ANS-SEE PICTURE
Positive= clumping
Negative= no clumping
tunic layers of veins and arteries - ANS-tunica intima, tunica media, tunica externa
main component of tunica interna (intima) - ANS-endothelial layer that lines the lumen of all
vessels
main component of tunica media - ANS-middle layer of artery; made up of smooth muscle
fibers and thick layer of elastic connective tissue
main component of tunica externa (adventitia) - ANS-collagen fibers that protect and reinforce
vessels
What is colloid osmotic pressure? - ANS-osmotic pressure exerted by plasma proteins
function of colloid osmotic pressure - ANS-serves to hold water within the vascular space
