Key Concepts

Hemolymph

Hemolymph is the circulatory fluid found in many invertebrates, particularly arthropods and mollusks, that is analogous to blood in vertebrates. It plays roles in transport, immunity, and sometimes in excretion, but it is not confined solely to blood vessels like vertebrate blood.

Open Circulatory System

An open circulatory system is a type of circulatory architecture in which the circulatory fluid, or hemolymph, is pumped into a body cavity (the hemocoel) where it directly bathes the organs, rather than being enclosed entirely within blood vessels. This system is characteristic of many invertebrates.

Hemocoel

The hemocoel is the primary body cavity found in organisms with an open circulatory system. It provides a space where hemolymph circulates, facilitating the exchange of nutrients, gases, and waste between the cells and the circulatory fluid, without the confinement of a closed vessel network.

Circulatory System

A circulatory system is the biological system responsible for the transport of nutrients, gases, wastes, and hormones throughout an organism's body. It can be organized in either a closed system, where the fluid is confined to vessels, or an open system, where the fluid freely bathes the organs in a body cavity.
