Question 1
1 / -0

Use the following diagram to complete the statement about the human nephron-

A
The composition of the filtrate would be must like plasma in the tubule next to the

B
The urine would be most concentrated in the collecting duct next to letter

C
Most of the glomerular filtrate is reabsorbed into pentubular capillary next to the

D
Conducting of urine to pelvis of the kidney from the structure next to the letter

E
Most water is reabsorbed by the structure next to the letter

Solution

A- Bowman's capsule
B- Proximal Convoluted Tubule
C- Loop of Henle
D- Distal Convoluted Tubule.
E- Collecting duct.
So, the correct option is 'The composition of filterate would be must like plasma in the tubule next'.
Question 2
1 / -0

Which stage of the urine formation occurs under high pressure of blood?

A
Ultrafiltration

B
Reabsorption

C
Absorption

D
Adsorption

Solution

Ultrafiltration takes place in Glomerulus of the Bowman's capsule of the nephron. The glomerulus consist of a tuft of capillaries, branched out of incoming or Afferent arteriole and outgoing Efferent arteriole
The diameter of the afferent arteriole is greater than that of the efferent arteriole and therefore blood flows under high pressure, where most of the substances and a large amount of water is filtered into the Bowman's capsule of the nephron, this filterate is called the ultrafiltrate and the process is called ultrafiltration
So, the correct answer is 'Ultrafiltration'
Question 3
1 / -0

Blood vessel entering into a glomerulus is called

A
Afferent arteriole

B
Efferent arteriole

C
Renal artery

D
Renal vein

Solution

The blood enters into the glomerulus via an artery called the afferent arteriole. This vessel brings the blood into the kidney for the removal of excess fluids and salts.
So, the correct answer is 'Afferent arteriole'.
Question 4
1 / -0

A brush border is formed in?

A
Distal convoluted tubule

B
Bowman's capsule

C
Proximal convoluted tubule

D
Loop of Henle
Solution
- The distal convoluted tubule is made up of typical absorptive epithelial cells. It passes close to the afferent and efferent arterioles of the same nephron, the brush border structure gradually increases the surface area.
Question 5
1 / -0

Pick the odd ones in each of the following groups are select correct option.

A
Renal pelvis, medullary pyramid, renal cortex, renal papilla

B
Afferent arteriole, henle's loop, vasa recta, efferent arteriole

C
Glomerular filtration, rennin hormone, hypertonic urine, collecting duct

D
Proximal convoluted tubule, distal convoluted tubule, henle's Loop
Question 6
1 / -0

Renal calculi is made up of

A
Uric, acid, cholestrol

B
Calcium oxalate, cystine

C
Cholesterol, calcium

D
Calcium phosphate & cholesterol

Solution

Renal calculi is a medical term used to describe kidney stones. They are hard deposits that form in the urine that are made up of minerals and salt acids like calcium oxalate and cysteine.
So the correct answer is 'Calcium oxalate, cystine'.
Question 7
1 / -0

Duct of Bellini is found in

A
Pancreas

B
Salivary gland

C
Medulla of mammalian kidney

D
Liver

Solution

The duct of Bellini or papillary duct is found in the medulla of the mammalian kidney. They receive renal filtrate and empty into the minor calyx. So, the correct answer is 'medulla of mammalian kidney'.
Question 8
1 / -0

Which part of Juxta medullary nephron is found in cortical region

A
Malpigian body

B
Proximal convulated tubule

C
Distal convulated tubule

D
Loop of henle

Solution

The Juxta medullary nephron is one in which the renal corpuscle (Malphigian corpuscle having the Malphigian body) is located in the cortex but near to the medulla and the other regions, such as the proximal convulated tubule, the loop of Henle, and the distal convulated tubule are located deeper in the medulla. The only region present in the cortex is malphigian body. So, the correct answer is A.
Question 9
1 / -0

In the kidneys, filtration of waste from blood takes place in the

A
Urinary bladder

B
Nephron

C
Glomerulus

D
Ureter
Solution
- Filtration mainly occurs in the glomeruli (tuft of capillaries).
- The blood pressure forces the blood plasma to diffuse through the capillary walls in the glomerulus.
- The blood plasma contains water, glucose, amino acids, and urea (nitrogenous waste).
- The blood cells and proteins being large in size do not pass through the capillary wall.
- So, the correct answer is 'Glomerulus'.
Question 10
1 / -0

Bowman's glands are found in _______________.

A
olfactory epithelium

B
external auditory canal

C
cortical nephrons only

D
juxtamedullary nephrons only

Solution

Bowman's gland is a type of tubular mucous glands that occur in the olfactory epithelium. Their ducts open on the olfactory epithelial surface. These gland secret watery mucus to protect and keep the epithelium moist.
So, the correct option is A
