BIOLOGY HUMAN SYSTEMS EXAM
PART B QUESTIONS AND ANSWERS
Renal artery - ANSWER-carries blood into kidney from aorta
renal vein - ANSWER-carries blood away from the kidney into inferior vena cava
aorta - ANSWER-carries blood away from the heart towards torso
inferior vena cava - ANSWER-carries blood from lower regions of the body to right
atrium
kidney - ANSWER-removes wastes from blood, and producing urine
ureter - ANSWER-carries urine from a kidney to the urinary bladder
urinary bladder - ANSWER-temporarily stores urine
urethra - ANSWER-carries urine from the urinary bladder to the exterior
Glomerular filtration - ANSWER-water and dissolved substances forced from blood
to bowmans capsule. high press in glomerulus aid filtration
tubular reabsorption - ANSWER-occurs in proximal tubule / loop of henle. 65% is
reabsorbed to body. sodium, glucose, other solutes actively transported. negatively
charged ions + water are passively absorbed.
tubular secretion - ANSWER-in distal tubule and collecting duct, more waste from
blood is moved to them, uses active transport for sodium, potassium, ammonia, uric
acid, urea, drugs, or poisons.
what do H+ ions do in tubular secretion - ANSWER-they are secreted into distal
tubule to maintain pH of blood
water reabsorption - ANSWER-occurs in collecting duct, causes it to become 4x
more concentrated.
Water balance - ANSWER-solute concentration in the blood
WHAT ARE THE KEY POINTS OF LYMPHATIC - ANSWER-immunity role, fluid
balance, clean up cellular wastes, absorb lipid subunits.
Type A blood components - ANSWER-A antigens, and anti B antibodies
Type B blood components - ANSWER-B antigens, and anti A antibodies
Type AB Blood components - ANSWER-Both A and B antigens, NO antibodies
