The body cavity of arthropods is

Options

A. Pseudocoel
B. Coelom
C. Haemocoel
D. Acoelom

Answer

**Step-by-Step Solution:**

1. **Understanding Body Cavities**: The body cavity in organisms can be classified into different types based on their structure and function. In arthropods, the body cavity is crucial for accommodating internal organs.

2. **Identifying the Body Cavity in Arthropods**: The body cavity present in arthropods is known as the **hemocoel**. This term is derived from the fact that it contains hemolymph, which is the fluid that circulates within this cavity.

3. **Function of Hemocoel**: The hemocoel serves as a space that houses the internal organs of arthropods. It allows for the circulation of hemolymph, which is similar to blood in other organisms but lacks red blood cells (RBCs) that give blood its red color.

4. **Circulatory System**: Arthropods possess an **open circulatory system**. This means that hemolymph is not confined to blood vessels but instead bathes the organs directly, allowing for the exchange of nutrients and waste products.

5. **Conclusion**: Therefore, the body cavity of arthropods is referred to as the **hemocoel**.

**Final Answer**: The body cavity of arthropods is called the **hemocoel**.
