The venous system of frog differs from that of mammals in the presence of:
The correct answer is option 'A' - Renal portal system.
Explanation:
The venous system in frogs differs from that of mammals in several ways. One of the major differences is the presence of the renal portal system in frogs.
Renal Portal System:
The renal portal system is a unique feature of the circulatory system in frogs. It is a specialized network of blood vessels that connects the kidneys with the hind limbs. This system is absent in mammals.
Structure and Function:
The renal portal system in frogs consists of two renal veins, the renal portal veins, and the renal portal hearts. The renal veins carry deoxygenated blood from the posterior parts of the body, including the hind limbs, to the kidneys. The renal portal veins are a set of small veins that carry blood from the hind limbs to the kidneys. The renal portal hearts are specialized muscular structures that help propel the blood through the renal portal veins.
The renal portal system serves several functions in frogs:
1. Excretory Function: The renal portal system allows the deoxygenated blood from the hind limbs to directly reach the kidneys. This ensures efficient filtration and removal of metabolic waste products from the blood.
2. Thermoregulation: Frogs are ectothermic animals, meaning their body temperature is regulated by the external environment. The renal portal system helps in maintaining body temperature by allowing the blood from the cooler hind limbs to mix with the warmer blood in the kidneys.
3. Oxygenation: The renal portal system also aids in oxygenation of the blood. The kidneys receive oxygenated blood from the pulmonary veins and mix it with the deoxygenated blood from the hind limbs. This helps in maintaining an adequate oxygen supply to the body.
Overall, the presence of the renal portal system in frogs is an adaptation that enhances the efficiency of excretion, thermoregulation, and oxygenation in these animals. This unique feature sets the venous system of frogs apart from mammals.
Therefore, the correct answer to the given question is option 'A' - Renal portal system.
The correct answer is option 'A' - Renal portal system.
