Introduction:
Earthworm belongs to the phylum Annelida and class Clitellata. It is a segmented worm with a long cylindrical body. The body is divided into several segments, and each segment has a pair of lateral hearts. In this article, we will discuss the number of lateral hearts found in earthworm.
Lateral Hearts in Earthworm:
The circulatory system of earthworm is a closed type and consists of blood vessels and hearts. The blood vessels carry the blood throughout the body, and the hearts pump the blood. Earthworm has five pairs of hearts, including a single dorsal heart and four pairs of lateral hearts. The dorsal heart is located in the anterior part of the body and pumps blood forward. The lateral hearts are located in the 7th, 9th, 11th, and 13th segments of the body.
Each lateral heart is a small muscular structure that pumps blood into the dorsal vessel. The lateral hearts are responsible for maintaining the blood pressure and circulation in the body. The number of lateral hearts in earthworm is an important characteristic that distinguishes it from other organisms.
