Frog Reproductive System Functions •Urinary Ducts - Tubes in a frog that carry urine from the kidneys to the cloaca •Urinary Bladder - The organ that collects and stores urine until released. The cloaca is the enlarged part where the large intestine joins the end of the alimentary canal. Invertebrate animals exhibit a wide range of reproductive behavior, but the bottom line is that at some point during the process, females create eggs and males fertilize the eggs, either internally or externally. The female reproductive system is one of the most vital parts of the human reproductive process. So far, numerous proteins and metabolites have been identified that provide us with valuable information to conduct a comprehensive analysis on seminal plasma and spermatozoa components and their functions. One endpoint that is attributed to this observed effect is the stimulation of Safety Warning: When working with sharp instruments, safety guidelines should be discussed with all participants. •Ova or Eggs - Female sex cell or gametes Females use their caudal fin to dig their redd (nest). The reproductive system is anatomically and histologically different in each sex. The methods of reproduction in fishes are varied, but most fishes lay a large number of small eggs, fertilized and scattered outside of the body. Starting from the head, bony fish consist of solid hard bones called cranium. Practice proper hygiene of the reproductive organs.
