😊 Hey everyone! Today we will be discussing the difference between coelom and haemocoel – two important body cavities found in animals.
Coelom and haemocoel are two types of body cavities found in most animals including humans. While both of them provide a space for organs and other tissues to develop, there are some major differences between them.
First of all, a coelom is a body cavity that is surrounded by a wall of tissue that is derived from the mesoderm – the middle layer of an embryo. It is a fluid-filled space which allows organs to move freely within the body, which is necessary for the proper functioning of the body.
On the other hand, a haemocoel is a body cavity that is derived from the ectoderm – the outer layer of an embryo. It is a blood-filled space that does not have a wall of tissue surrounding it. Instead, it is filled with a jelly-like substance known as haemolymph.
Another major difference between the two body cavities is that the organs in a coelom can move freely within the body, whereas organs in a haemocoel are attached to the body wall with muscles and ligaments. This means that the organs in a haemocoel cannot move freely within the body.
Finally, a coelom has two layers – the coelomic epithelium, which lines the inner surface of the body cavity, and the mesenteries, which attach the organs to the body wall. The haemocoel, on the other hand, only has one layer – the haemolymph.
In conclusion, the main difference between a coelom and a haemocoel is that the former is a fluid-filled space surrounded by a wall of tissue and the latter is a blood-filled space without a wall of tissue. Both of them provide space for organs and other tissues to develop, but the organs in the coelom can move freely within the body, whereas the organs in the haemocoel are attached to the body wall.
