Circulation System of Phylum Arthropoda
The arthropods have open circulatory system. It consists of the dorsal heart and arteries which are in small numbers in insects and very extensive in large creatures like crabs. Blood is delivered into the tissue spaces called hemocoels by arteries. Small creatures like crustaceans and a few insects like larvae have hemoglobin in their blood just like humans. A changing number of matched openings are situated along the length of the heart and license blood to stream in when the valves are open.
Phylum Arthropoda
Phylum Arthropoda is the largest phylum in the Kingdom Animalia and it includes insects. Arthropoda makes up more than two-thirds of all known species worldwide. The phylum Arthropoda characteristics include jointed appendages, a well-organized body structure with a segmented design, and a tough exoskeleton made of chitin. The Arthropoda body is divided into three sections: head, thorax, and abdomen.
The Phylum Arthropoda examples include insects such as ants, and butterflies arachnids like spiders and scorpions, crustaceans such as crabs, lobsters, and shrimp, as well as myriapods including centipedes and millipedes. In this article, we will cover the Phylum Arthropoda and its classification, and characteristics in detail.
