Life Processes Worksheet-40
True or false:
-
The purpose of formation of urine is to filter out the waste products from the lymph.
-
Excretion means removal of Nitrogenous waste from the body.
-
Renal artery enters the kidney and renal vein and ureter comes out from the kidney.
-
The urine stored in the bladder is carried out of the body by a tube called ureter.
-
Two normal constituents of urine are blood and sugar.
-
Micturition is under the control of sphincter muscles.
-
Loop of Henle helps in selective reabsorption.
-
Urine is a secretory product.
-
Kidney helps in only osmoregulation.
-
Thousands of nephrons are present in each kidney.
-
Urea is produced in kidney.
-
The neck of urinary bladder is called ureter.
-
If excess water intake dilutes body fluids, ADH secretion increases.
-
Reabsorption of water occurs in Henle’s loop.
-
Absorption and secretion are functions of tubular part of nephrons.
-
Micturition is expulsion of urine from the bladder along the urethra.
-
Normally urine has alkaline pH while blood has acidic pH.
-
Glomerular filtrate contains plasma proteins, urea, glucose, water, blood corpuscles, etc.
-
The process by which water level of body maintained is termed as osmoregulation.
-
The walls of ureter are lined by transitional epithelium.
-
Left kidney is slightly lower than the right one due to presence of liver on left side of abdomen.
-
The male urethra is longer than female urethra.
-
Glomerulus and Bowman's capsule together called Malpighian body.
-
Hemodialysis is called artificial kidney.
-
Protein free fluid is filtered from blood plasma into Bowman's capsule.
-
Urine reaches the bladder from kidneys through the ureters.
-
Fishes can excrete out nitrogenous waste in the form of nitric acid.
-
Plants generally excrete out by the process of diffusion from different parts.
-
Waste products in plants may be stored as resins and gums especially in old xylem.
-
Photorespiration and photosynthesis are opposite to each other functionally.
