The correct sequence of urine movement is

evs - i excretion in living organisms other systems in the body excretory system in human human excretory organs

  1. Bladder --> Kidney --> Ureter -->Urethra

  2. Bladder -->Urethra -->Kidney -->Ureter

  3. Kidney -->Bladder -->Ureter --> Urethra

  4. Kidney -->Ureter -->Bladder -->Urethra

Show answer
Correct Option: D
Explanation:
Urine is formed in the kidney. The tubes which connect the kidney and urinary bladder are known as the ureter. From the kidney, urine is propelled into the urinary bladder through ureters which are made of smooth muscle fibres. The bladder stores urine, allowing urination to be infrequent and can be controlled. The urethra is a long tube which connects urinary bladder to the urinary meatus for removal of urine from the body. In males, urethra travels through the penis and meet the urethral meatus located at the tip of the penis. In females, urethra connects to the urethral meatus above the vagina. The urethra is also known as the urinary opening. So the correct sequence of urine movement is Kidney -->Ureter -->Bladder--> Urethra.
So, the correct answer is 'Kidney -->Ureter -->Bladder -->Urethra'.

Average quantity of urea excreted daily humans per day is

evs - i excretion in living organisms other systems in the body excretory system in human human excretory organs

  1. 10 - 15 g

  2. 25 - 30 g

  3. 40 - 50 g

  4. 100 - 500 mg

Show answer
Correct Option: B

  2. active transport of chloride ions from the filtrate into the peritubular tissues

  3. release of nitrogenous wastes into the intestines

  4. hormonal control of permeability of walls in various excretory tubules

Show answer
Correct Option: C

No-threshold substances (such as creatinine sulfate). The primary threshold substance is Urea and uric acid.

So the correct option is 'Urea and uric acid.'
