Ch. 19A Flashcards
1) Which of the following do the kidneys not regulate;
1)Extracellular fluid, volume,blood pressure ,blood salt levels, pH waste and foreign substance
2) Where in the kidneys is urine produced?
2)nephrons
3) What is the name of the process of producing urine?
3)urination
5) What is the name of the process of releasing urine from the body?
5)micturation
6) Where are most of the nephrons in a kidney found?
6)cortex
7) Where are most of the collecting ducts in a kidney found?
7)medulla
8) What blood vessels bring blood into the glomerulus?
8)afferent arterioles
9) In what structure is filtrate produced?
9)glomerulus/ bowman capsule
10) What blood vessels move blood away from the glomerulus?
10)efferent artieroles
11) What happens in the peritubular capillaries?
11)reabsorption and capillaries active secretion
12) The majority of all reabsorbed water is removed from the filtrate in the;
12)proximal tubules
13) What two things are reabsorbed in the Loop of Henle?
13)salt and water
14) If the body produces 10 liters of filtrate in a given time period, how much of that original 10 liters is reabsorbed by the LOH?
14)90%= 1L
15) What happens in the distal tubules?
15)salt and water balance
17) Water is reabsorbed from the urine in the urinary bladder; True (A) or False (B)
17)F
18) Less than 1/10th of all filtrate produced in the kidneys is lost as urine normally; True (A) or False (B)
18)T
20) How is filtrate different from plasma?
20)missing large plasma protien
21) What two components of blood never enter Bowman’s capsule?
21)form elements and plasma protien
23) What pushes the filtrate out of the blood and into the Bowman’s capsule?
23)hydrostaric BP
24) What causes some filtrate to immediately move back into the blood?
24)colloidal osmatic pressure
25) If 10 liters of blood passes through the kidneys during a given time period, how much of the blood volume is initially lost as filtrate?
25)20%-2L
26) All of your blood plasma is filtered many times per day, normally; True (A) or False (B)
26)T
27) If your blood pressure dips slightly, your filtration rate will dip accordingly; True (A) or False (B)
27)F
28) GFR stands for;
28)Glomerular filteration rate
29) What two processes in the blood vessels help keep GFR constant under a variety of blood pressures?
29)vasocontriction
Vaso dialtion
