Question

mention the pathway of urine starting from the organ of its formation

Answer 1

-Urine is formed when there is glomerular filtration in the nephrons of the kidneys. 
1) Urea and plasma from blood is filtered in the bowman's capsule.
2)The urine moves into the proximal convoluted tubule, into the descdnding loop of henle, then ascending loop and up into the distal convoluted tubule - all these being parts of the nephron.
3)Once the urine moves out of the nephrons, it gets into the collecting tubes of the kidney.
4)From the collecting tubules, the urine enters into the ureters 
5)The ureters then drain the urine into the urinary bladder.
6)From the bladder the urine moves into the urethra. It is from the urethra that the urine is passed out of the body.
