Bladder
Urethra

Question 2

Kidney

Answer 2

Principal organ of the urinary system

Question 3

Ureter

Answer 3

Tubes that carry urine from the renal pelvis to the bladder

Question 4

Bladder

Answer 4

Stretchable organ that acts as a reservior

Question 5

Urethra

Answer 5

Small tube from the bladder neck to the external meatus

Question 6

Kidney 1

Answer 6

2 bean shaped kidneys that lie in the abdominal wall, one on each side of the vertebral column behind peritoneum and below the diagphram

Question 7

Function of the kidney

Answer 7

Regulate volume and composition of extra cellular fluid
Maintain acid base balance
Control blood pressure and produce renin
Produce erythropoietin
Excrete waste products and foreign compounds
Conversion of vitamin d

Question 8

Nephron

Answer 8

Functional unit of the kidney, each kidney contains approximately 1million nephrons

Question 9

Parts of the nephron

Answer 9

Glomerulus
Proximal tubule
Loop of henle
Distal tubule
Collecting duc

Question 10

Glomerulus

Answer 10

Responsible for blood filtration to form urine ( tiny ball shaped structure composed of capillary blood vessels)

Question 11

Proximal tubule

Answer 11

Begins with renal pole to the loop of henle. Reabsorbed filtered glucose

Question 12

Loop of henle

Answer 12

Recover water and sodium chloride from urine ( long u-shaped portion of tubule conducts urine km each nephron

Question 13

Distal tubule

Answer 13

Reabsorbes calcium, sodium, chloride, and regulates the ph of urine by secreting protons and absorbing bicarbonate

Question 14

Collecting duct

Answer 14

Twisting tube that collects urine from nephron and moves it into renal pelvis and ureter

Question 15

Urine formation

Answer 15

Glomerular filtration
Tubular reabsorption
Tubucular secretions

Question 16

Glomerular formation

Answer 16

Water and solutes smaller than protien are forced through the capillary walls and pores of the glomerular capsule into the renal tubule

Question 17

Tubular reabsorption

Answer 17

Water, glucose, amino acids and needed ions are transported out to filtrate into the tubule cells and then enter the capillary blood.

Question 18

Tubular secretion

Answer 18

H, k , createnine na d drugs are removed from the peritubular

Question 19

Ureter

Answer 19

Tubes that carry urine from renal pelvis to the bladder
Hollow muscular tubes 25-30 cm long
There are where renal pelvis joins the ureter is called pelvouretic junction and the ureter inserts into either side of the bladder at the base vesicoureteric junction

Question 20

Bladder

Answer 20

Reservoir of urine
Lies in the pelvic cavity and the size and position depending on the volume of urine it contains
Open into the urethra at the lowest point
On average 200-250 ml urine causes distension and the urge to urinate

Question 21

Urethra

Answer 21

Small tube that incorporates the smooth muscle of the bladder neck and extending the striated muscle of the external meautus

Question 22

Urethra primary function

Answer 22

Control voiding

Serve as a conduit for urine from the bladder to the outside of the body during the voiding

Question 23

Femal urethra size

Answer 23

2.5 - 5 cm

Question 24

Male urethra

Answer 24

20-25 cm ( associated with the urinary and reproductive system)
