1

Main organ in urinary system

Kidneys

2

The functional unit of kidney

Nephron

3

Each kidney contains how many nephrons?

1,00,000 nephrons

4

Kidney contains how many lobes and segments?

8-18 lobes and 5 segments

5

The kidneys are located in retroperitoneal at level of?

T-12 - L3

6

It is the gateway of the kidneys

Renal hilum

7

structures that passes through renal hilum

Renal artery, vein
Ureter

8

Blood supply of Kidneys

Renal artery

9

Renal artery is a branch of what artery?

Superior mesenteric artery

10

Renal corpuscles is composed of?

Glomerulus and Bowman's compose

11

The site of blood filtration that contains mesangial cells

Glomerulus

12

This measures the proper functioning of kidneys

Glomerular filtration rate (GFR)

13

GFR is measured by?

Amount of Innulin and Manitol in urine

14

Amount of GFR per minute ____
per day ____

per minute: 120-125mL
per day : 170,000 - 180,000 mL

15

The entrance and exit of kidneys

Entrance- afferent
Exit- efferent

16

Enlarge diameter of efferent means?

less waste, less filtration

17

Increase Innulin means?

increase GFR

18

Proteins that will measure GFR

Innulin and Mannitol

19

It is the site of WATER FILTRATION that contains Podocytes.

Bowman's capsule

20

Tubule that regulates the pH of filtration by exchanging Hydrogen ions and Bicarbonates.

Proximal tubule

21

Proximal tubule is line with

Simple cuboidal epithelium with Microvilli for absorption

22

Tubule that reabsorbs the GLUCOSE and AMINO ACIDS

Proximal convoluted tubule

23

Proximal convoluted tubule produces what to buffer the hydrogen ions?

Ammonia

24

2 buffering agent of kidney

Bicarbonate
Ammonia

25

Organ resistant to pH change

KIDNEY

26

The amount of GLUCOSE filtered per day is

160-180 mg/dL

27

The amount of GLUCOSE excreted per day is

0 mg/dL

28

When the glucose is exceeds to 180 mg/dL, the PCT starts to excrete glucose, known as the

RENAL THRESHOLD FOR GLUCOSE (RTG)

29

Tubule that contains the highest OSMOLARITY

Loop of henle

30

section of the loop of henle that is the only permeable to SODIUM

Descnding limb
