Hint: In adult and frog embryos, this type of kidney is present. From the middle part of the intermediate mesoderm, a mesonephros forms soon after each pronephros.
Complete Answer:
- The function of the kidney of a frog is to excrete surplus water. Frogs often use their kidneys on the ground to replace excess water in the skin by evaporation. In vertebrates, there are three excretory glands. These are pronephros, mesonephros, and metanephros. These three organ systems are developed from the intermediate mesoderm and are formed in a defined sequence in time and space. The pronephros is first developed and is the most simplest of the vertebrates excretory organs, consisting of a tubule, a duct, and glomus.
- Pronephros is the fundamental type of excretory organs that match the first stage in kidney development. In the anterior regions the functioning kidney of a frog tadpole is prophylactic developed from nephrotome.
- Pronephros is succeeded by Mesonephros. This is the primary excretory organ for fish and amphibians of marine vertebrates and as a temporary kidney of reptiles, birds and mammals. - The mesonephros is a kidney-like structure. Mesonephros is the frog's functioning kidney.
The embryonic excretory organs metanephros in higher vertebrates is the third category. It is a continuous and functional renal.
Thus, the correct answer is option B. i.e., Mesonephric.
Note: Pronephros, mesonephros and metanephros are three distinct renal organs, which in succession act as the vertebral excretory system when the kidney is formed. These three organ systems come from the middle mesoderm and evolve in a well-defined spatial and temporal series.
