Question
Fishes have ____ chambers of the heart.
- 2
- 3
- 4
- 5
Hint:
Fishes belong to the Pisces kingdom.
The correct answer is: 2
- Fishes consist of two chambers in their heart.
- According to the animal kingdom, the fishes are known to be belonging to the Pisces kingdom. All Pisces have two-chambered hearts. They consist of one auricle and one ventricle.
- The blood gets purified or oxygenated through the gills of the fishes. The heart just acts as a pumping organ for them.
- They lack three-chambered hearts like amphibians and four-chambered hearts like mammals.
Since the chambers are not well separated, there is a chance of mixing of blood which can be purified by the gills of the fishes.
