How do the sturcture and connectivity of the urinary bladder of the fetal pig differ from those of the urinary bladder of the human?

The urinary bladder of fetal pig is elongated sac and humans is hollow and muscular.

Explanation:

The urinary bladder of fetal pig is also called as allantoic bladder. The bladder is a collapsed long sac present between arteries. It is tapered near to posterior side to form urethra to joins the pelvic cavity.

The urinary bladder in humans is located in the posterior side of pelvic cavity. It is hollow muscular organ that is held at its place by folds of the peritoneum. The human urinary bladder collapses on micturition. The micturition is the process of excretion of urine. The trigone is the triangular shaped floor of bladder. This bladder connected with ureters endings and opens into urethra.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
