About this document
Mollusca Respiratory Systems Explained by Helmi Zzt is a document available to read on EtoBox.
The document summarizes respiration systems in different organisms. It discusses how protozoans, poriferans, coelenterates, annelids, mollusks, echinoderms, and arthropods breathe. Many early organisms rely on diffusion of gases through their skin or cell membranes. Annelids, mollusks, and some protozoans lack specialized respiratory organs. Mollusks and arthropods typically use gills to extract oxygen from water, while some mollusks use lungs to breathe air.
