Its aperture lies below and opposite to the openings of ureters. From the glomerulus blood is collected by efferent arteriole which joins with a renal vein. The glomerular filtrate passes through the thin wall of the Bowman’s capsules into the lumen of uriniferous tubules and the filtered blood goes into renal vein through the efferent arteriole. They serve as a sort of storehouse of nutrients which are provided to the developing spermatozoa and during hibernation. Content Guidelines 2. Reproduction Human Reproductive System PMF IAS. Hence, it is called a urinogenital duct. The ovary is enveloped by mesovarium, a … Bidders canal and collecting tubules. The froghas been historically been used as an amphibian animal model of development due to the ease of observation from the fertilized egg through to tadpole stage.

A frog has a liver, stomach, reproductive system, somewhat nuerological, and mucle/fat tissues similar to us. Blood comes to glomeruli from afferent arterioles which have a wider lumen then the capillaries so that the blood in glomeruli is under high pressure which causes filtration of blood.
