The tube arising from the notch of the kidney on the median
side and connecting behind with the urinary bladder.
Ureter
The tube that passes the urine to the outside of the body.
Urethra
The inner lighter coloured region of the kidney.
Renal Medulla
Knot-like mass of blood capillary inside Bowman’s capsule.
Glomerulus
The structural and functional unit of the kidney.
Nephron
The blood vessel which :
a. enters malpighian capsule
b. leaves malpighian capsule
(a) Afferent arteriole (b) Efferent arteriole
Loop of Henle, Bowman’s capsule, distal convoluted tubule,
glomerulus, proximal convoluted tubule.
(i) Name the structure to which the listed parts belong.
(ii) Rearrange the parts in their proper sequence from the starting
point to where they end.
(i) Kidney Tubule
(ii) Glomerulus → Bowman’s capsule → Proximal convoluted
tubule → Loop of Henle → Distal convoluted tubule
The process of removal of unwanted metabolic wastes from the body is called
Excretion
The organ that does not belong to the excretory system
1. Urethra
2. Uterus
3. Ureter
4. Urinary bladder
Uterus
Which of the following is not an example of secretion ?
1. Saliva
2. Gastric juice
3. Urine
4. Milk
Urine
The nephrons discharge the urine at
1. Urinary bladder
2. Ureter
3. Renal pelvis
4. Renal pyramid
Renal pelvis
An organ that produces urea :
1. Kidney
2. Liver
3. Ureter
4. Urethra
Liver
The accumulation of high quantities of urea in the human body is
termed as :
1. Diuresis
2. Dialysis
3. Uremia
4. Micturition
Uremia
The process of tubular secretion occurs in :
- PCT
- DPT
- DDT
- DCT
DCT
The outer region of kidney containing the Bowman’s capsule.
Renal cortex
The tuft of capillaries inside the Bowman’s capsule.
Glomerulus
The part of kidney tubules where the term urine is first used
for the fluid in it.
DCT
The organ which filters urea.
Kidney
The organ through which urea is released outside the body of a
human being.
Urethra
The specific pigment found in urine.
Urochrome
Write in sequence
Afferent arteriole, renal vein, secondary capillary network,
glomerulus, efferent arteriole
Afferent arteriole, glomerulus, efferent arteriole, secondary
capillary network, renal vein.
Write in sequence
Renal artery, urethra, ureter, kidney, urinary bladder.
Renal artery, kidney, ureter, urinary bladder, urethra.
Three nitrogenous wastes of our body.
- Urea
- Uric acid
- Ammonia
Three organic wastes of our body.
- Urea
- Uric acid
- Creatinine
Three inorganic wastes of our body.
- Common salt (NaCl)
- Iron
- Calcium
Three main parts of our urinary system.
- Kidney
- Urinary bladder
- Ureter
Six main parts of nephron.
- Bowman’s capsule
- Glomerulus
- Renal capsule
- Proximal convoluted tubule (PCT)
- Henle’s Loop
- Distal convoluted tubule (DCT)
Three stages of urine formation.
- Ultrafiltration
- Reabsorption
- Tubular secretion
Three types of fluids in different parts of a nephron.
- Glomerular filtrate
- Glomerular filtrate with glucose and sodium
- Urine
Choose the odd one out
Kidney, ureter, neuron, urethra, urinary bladder
neuron
others belong to excretory system
Choose the odd one out
Ammonia, urea, excess sodium chloride, uric acid
Excess sodium chloride
Others are organic nitrogenous wastes.
PCT
Proximal convoluted tubule
DCT
Distal Convoluted Tubule
ADH
Antidiuretic hormone
ORS
Oral Rehydration Solution
Location of Kidney
It is located on either side of the backbone and
protected by the last two ribs.
Location of uriniferous tubule
Uriniferous tubule begins in the cortex;
the tubule dips down to the medulla, then return to the cortex
before draining into the collecting duct.
Malpighian capsule
It comprises of Bowman’s capsule
and glomerulus and is located in the kidney tubule.
Loop of Henle
It runs in the medulla to turn back and to
re-enter the cortex to continue into the next convoluted region of
the tubule.
An organic component of urine
Urea
The tube that expels urine from the body
urethra
The outer region of the kidney
Renal cortex
The liquid present in the bowman’s capsule
Glomerular filtrate
Excretory product from lungs
Carbon di oxide
The organ which produces urea
Liver
The main nitrogenous waste in man
Urea
The hormone involved in reabsorption of water from the kidney
ADH
The term used for bowman’s capsule and glomerulus together
Malphigian capsule
The form in which glucose is stored in liver
Glycogen
The blood vessel leaving kidney
Renal vein (efferent arteriole)
The process by which kidneys regulate the water content in human body
Osmoregulation
Most of the glucose is absorbed in
PCT
Automatic self regulation of salt and water within the body is called
Homeostasis
Protein diet makes urine
acidic
Nitrogenous wastes are formed by the breakdown of
protein
Glomerulus helps in
ultrafiltration
Afferent arteriole is ________________ than efferent arteriole
