The urinary system

Question 1

what are the 4 major parts in the urinary system?

Answer 1

ureter
urethra
bladder
kidneys

Question 2

functions of the 4 major parts in the urinary system

Answer 2

kidneys= filter blood and regulates the acid balance
ureters= 2 thin tubes that carry urine from kidneys to the bladder
urethra= exit of urine
bladder= stores the urine

Question 3

what do kidneys regulate?

Answer 3

blood pH
blood volume
blood pressure

Question 4

what does a kidney internally and externally consist of

Answer 4

internal= renal medulla
external= renal cortex

Question 5

simply how does blood enter kidneys?

Answer 5

renal artery to aorta(abdominal aorta) to renal vein

Question 6

Renal blood flow

Answer 6

RSIAIAGEPIAIR

renal artery
segmental arteries
interlobar arteries

interlobular arteries
afferent arteries
glomerulus capillaries
efferent arterioles
peritubular capillaries
interlobular vein
arcuate vein
interlobar vein
renal vein

Question 7

what are the 2 main parts of the nephron

Answer 7

renal corpuscles and renal tubule

Question 8

list the parts of a nephron and what they include

Answer 8

glomerulus= has mesangial,capillaries,efferent/afferent arterioles
Renal corpuscle= has a glomerulus and Bowmann’s
capsule
PCT (proximal convoluted tube)= reabsorbs fluid from filters fluid
Loop of henle= water reabsorption and salt
DCT(distal convoluted tube)= balances acidity by secreting/reabsorbing substances
Collecting duct= receives fluid from multiple nephrons to form urine

Question 9

what is the function of a glomerulus and bowman’s capsule?

Answer 9

glomerulus= filters water and solutes in blood plasma
bowmanns=collect the filtered fluid

Question 10

what 3 things must the nephron perform to keep homeostasis in blood?

Answer 10

1. glomerular filtration= filters water/solute in blood plasma
2. tubular reabsorption= the needed components and water back to body
   3.tubular secretion= secrete material into filtrate for disposal

Question 11

label a nephron

Question 12

what are the 3 pressures that promote glomerulus filtration?

Answer 12

1. GBHP= glomerulus blood hydrostatic pressure is the force for the liquid to go through the filtration
2. BCOP= blood colloid osmotic pressure is caused by large proteins
   3.CHP= capsular hydrostatic pressure is the pressure exerted by the fluid in bowmanns capsule

Question 13

what is NFP and state its formula

Answer 13

net filtration pressure is the pressure that pushes the fluid from the blood vessels in the kidneys to the bowman’s capsule

GBHP-BCOP-CHP

Question 14

define micturtion

Answer 14

emptying of the bladder

Question 15

examples of homeostatic imbalances

Answer 15

kidney stones
UTI
renal failure
urinary bladder cancer
