Question

The body cavity of arthropods is
A. Pseudocoel
B. Coelom
C. Haemocoel
D. A coelom

Answer 1

Hint: Arthropods are invertebrate creatures having exceptionally evolved receptors, sectioned bodies, and exoskeleton. They additionally have a ventral sensory system with two-sided balance. Models are millipedes, bugs, centipedes.

Complete answer: Arthropods have a body cavity that is known as a coelom which is a film lined hole between the gut and the body divider that fits the inward organs. The coelom is the body cavity in the majority of the creatures. In Arthropoda, the body cavity is loaded up with blood and this is called haemocoel. Haemocoel is the body depression that is loaded up with blood that emerges in the undeveloped mesoderm and it is an augmented blastocoel and goes about as a hydrostatic skeleton.
Furthermore, it is an augmented blastocoel and goes about as a hydrostatic skeleton. This hole creates in mollusks, arthropods, and annelids with the parting of the mesoderm. It is called schizocoelom and this is loaded up with blood.
Hence, the correct answer is Option C
Additional information:
Nematodes have a space between the body divider and the stomach related parcel and are not fixed with a tissue. Along these lines, it isn’t considered genuine coelom. Arthropod’s essential interior pit is a haemocoel, which obliges their inward organs and through their hemolymph (simple of blood), the course in their open circulatory framework. The body cavity is known as the sinus which is separated into the pericardial sinus, perivisceral sinus, and perineural sinus.

Note: A body depression is called coelom which is found in the arthropods. Inside the coelom, organs can move unreservedly, develop freely and it shields them from the shocks. Arthropods have an open circulatory framework which comprises a heart and blood-filled haemocoel.
