Question 13

Question 14

Location of Kidney

Answer 14

Against back muscle in upper abdominal cavity

Question 15

Parts of Urinary System

Answer 15

Kidneys, Ureters, Bladder, Urethra

Question 16

Internal Parts of Kidney

Answer 16

Capsule, Cortex, Nephrons, Medulla, Renal Pyramid, Renal Columns, Renal Papilla, Minor Calyx, Major Calyx, Renal Pelvis, Renal Pelvis

Question 17

Renal Blood Pathway

Answer 17

Renal Artery, Afferent arterioles, Glomerular Capillaries, Efferent arterioles, Peritubular capillaries, venule, vein, heart

Question 18

Tubular Fluid Patrhway

Answer 18

Bowman’s Capsule, Proximal Convoluted tubular, Nephron Loop Decending, Nephron loop Acending, Distal convoluted tubule, collecting duct, minor calyx, major calyx, ureter, bladder, urethra

Question 19

3 processes that take place in nephron

Answer 19

Filtration, reabsorption, Secretion

Question 20

2 types of Nephrons

Answer 20

Cortical- commom, more in cortex Juxtamedullary deeper in cortex dip into medulla, handle water regulation

Question 21

Juxtaglomerular apparatus

Answer 21

plays role in secretion of renin when blood pressure drops

Question 22

Renin-angiotensin system

Answer 22

Protein Angiotensinogen produced by liver, Kidney secrets Renin when blood pressure drops in the Juxtaglomerular Apparatrus, Renin combines with Angiotensinogen to form Angiotensin I, Lung secrets ACE to form Angiotensin II which causes Aldosterone secretion (Na+), and ADH (water retention).

Question 23

Proximal Convoluted Tubular

Answer 23

where most of reabsorbtion takes place, water, Na+, amino acids, glucose

Question 24

desending nephron loop

Answer 24

H2O reabsorbtion, passive

Question 25

Ascending nephron loop

Answer 25

Na+, Cl-, K+ Active

Question 26

Distal Convoluted Tubluar

Answer 26

Na+, Cl-

Question 27

Tubular Secretions

Answer 27

secretions from peritubular capillaries into tubulars: penucillin, histamine, ammonia, potassium ions

Question 28

Aldosterone and ADH

Answer 28

increases Na+ absorption into blood form DCT, ADH punches holes in collecting duct releasing H2O back into blood. Low ADH diluted urine, High ADH= concentrated urine

Question 29

Glomerular Filtration Rate

Answer 29

Glomerular Hydostatic pressure most important, Glomerular Capsule Hydrostatic pressure and Glomerular Osmotic pressure oppose this. Arrerent Arteriole is a larger opening then then efferent artriole this increases pressure, favoring filtration

Question 30

Glomerular Filtration Rate

Answer 30

180 L 24 hours

Question 31

Urine formed in 24 hours

Answer 31

.6L- 2.5L

Question 32

renal plasma threshold

Answer 32

when more glucose molecules are in filtrate then the active transport mechanism can handle

Question 33

Urea

Answer 33

by product of break down of amino acids, 80% reabsorbed

Question 34

uric acid

Answer 34

product of amino acid breakdown

Question 35

urine

Answer 35

95% water

Question 36

renal clearance test

Answer 36

how fast substance can pass through kidney flitration, inulin and creatinine

Question 37

automatic bladder

Answer 37

when micturition reflex triggers internal urethral sphiceter and urniation occurs

Question 38

micturtion reflex

Answer 38

stretch receptors in bladder stimulated and send signal to micturtion center is spinal cord, which acticates detrusor muscle to contract rhythmically, gives you feeling like you have to go
