URINARY SYSTEM + ENDOCRINE SYSTEM

Which of following cell can be found within visceral layer of bowman's capsule

• mesangial cell

• podocytes

• juxtaglomerular cell

• macula densa

Which of the pressure within renal corpuscle that encourage filtration ?

• Blood colloid osmotic pressure

• Capsular hydrostatic pressure

• Glomerular blood hydrostatic pressure

• Osmosis pressure

Which part of renal tubule that ONLY involved in re-absorption of fluid?

• Late DCT

• Loop of Henle

• Early DCT

• PCT

When GFR is high, Nacl concentration within renal tubule will W. Thus X will secrete Y to cause constriction of Z.

What is W,X,Y,Z ?

• W: High X : Macula densa Y : adenosine Z : afferent arterioles

• W: High X : mesangial cell Y : adenosine Z : efferent arterioles

• W: Low X : Macula densa Y : adenosine Z : afferent arterioles

• W: Low X : Mesangial cell Y : renin Z : efferent arterioles

Which of the following statements is TRUE regarding neural regulation of micturition process ?

• Activation of pudendal nerve cause relaxation of internal urethral sphincter

• Contraction of urinary bladder is cause by activation of sympathetic nerve

• Contraction of internal urethral sphincter is caused by of activation of hypogastric nerve

• Relaxation of external urethral sphincter is caused by activation of somatic nerve fiber.

What is the outermost layer of the kidney?

• Perirenal fat layer

• Gerota's fascia

• Renal fat layer

• Renal capsule

Which of the following hormones involved in increasing blood pressure?

i. ANP

ii. ADH

iii. Aldosterone

iv. PTH

• i and ii

• ii and iii

• i and iv

• iii and iv

When someone is having dehydration, ANP will be release to increase reabsorption of water and thus increase the osmolarity.

• TRUE

• FALSE

When blood pressure is high, arterioles will become W stretch. It will cause calcium X and lead to Y of arterioles to Z.

• W: Less X: efflux Y: vasoconstriction Z: reduce blood flow

• W: Less X: influx Y: vasodilation Z: increase blood flow

• W: Less X: efflux Y: vasodilation Z: reduce blood flow

• W: more X: influx Y: vasoconstriction Z: reduce blood flow

The structure of Urinary bladder that allow it to receive maximum amount of urine is called __________.

• destrusor muscle

• transtional epithelium

• rugae

• external orifice
