Heart Function in Different Animal Groups
In the animal kingdom, the function of the heart is to pump oxygenated blood to different parts of the body. However, there are certain groups of animals in which the heart does not pump oxygenated blood. Let's examine each option to determine the correct answer.
a) Pisces only
Pisces refers to the group of animals that includes fish. Fish have a two-chambered heart, which consists of a single atrium and a single ventricle. The heart pumps deoxygenated blood to the gills, where it gets oxygenated. The oxygenated blood then flows to the rest of the body.
b) Amphibians only
Amphibians refer to a group of animals that includes frogs, toads, and salamanders. Amphibians have a three-chambered heart, consisting of two atria and a single ventricle. The heart pumps both oxygenated and deoxygenated blood, resulting in some mixing in the ventricle. However, the majority of the oxygenated blood is pumped to the systemic circulation.
c) Amphibians and reptiles
Reptiles, such as snakes, lizards, and turtles, also have a three-chambered heart similar to amphibians. They have two atria and a single ventricle. The heart pumps both oxygenated and deoxygenated blood, with some mixing occurring in the ventricle. The oxygenated blood is primarily directed to the systemic circulation.
d) Pisces and amphibians
Combining the information from options a) and b), we see that both fish (Pisces) and amphibians have hearts that pump oxygenated blood. Fish have a two-chambered heart, while amphibians have a three-chambered heart. Therefore, this option is incorrect.
Correct Answer: a) Pisces only
Based on the above analysis, the correct answer is option a) Pisces only. Fish, belonging to the group Pisces, have hearts that pump deoxygenated blood to the gills for oxygenation.
