Correct option is A
The Correct Answer Is: (A) Salamander
Explanation:
A salamander belongs to the class Amphibia, and all amphibians, including frogs, toads, and newts, have a three-chambered heart.
Information Booster:
- A three-chambered heart consists of:
- Two atria (left and right)
- One ventricle
- In amphibians, the oxygenated and deoxygenated blood mix partially in the single ventricle.
Animals with a Two-Chambered Heart:
- Found in fishes (e.g., Rohu, Sting Ray).
- Consists of one atrium and one ventricle.
- Blood is pumped in a single circulation loop.
Animals with a Three-Chambered Heart:
- Found in amphibians and most reptiles (except crocodiles).
- Consists of two atria and one ventricle.
- Blood mixing occurs, making it less efficient than a four-chambered heart.
Animals with a Four-Chambered Heart:
- Found in birds and mammals (e.g., Sparrow, Humans, Lions, etc.).
- Consists of two atria and two ventricles, ensuring complete separation of oxygenated and deoxygenated blood.
- Provides higher efficiency in oxygen transport, suitable for warm-blooded animals.
Additional Knowledge :
Rohu (Fish):
- Belongs to the Pisces class. Has a two-chambered heart (one atrium and one ventricle).
- Single circulation system (blood flows through the heart once per cycle).
Sparrow (Bird):
- Birds have a four-chambered heart (two atria and two ventricles). Complete separation of oxygenated and deoxygenated blood.
- Birds have a four-chambered heart (two atria and two ventricles). Complete separation of oxygenated and deoxygenated blood.
Sting Ray (Fish): where blood flows from the heart to the gills for oxygenation and then to the body.
