The circulatory system in Molluscs is quite well-developed. Almost all the members of the phylum (excepting Scaphopoda which lacks a distinct heart) have distinct heart which receives oxygenated blood from the respiratory organs and conveys it to the different parts of the body.

Molluscs have gills in their mantle cavity, which are used for respiration to exchange oxygen and carbon dioxide. Gills are employed by some bivalves for both filter feeding and breathing. Land molluscs have pulmonary sacs or cavities, which are aerial respiration organs. Here, let’s discuss the types of respiration in molluscs. Table of Contents

2024年10月2日 · Mollusca exhibit various types of respiration, depending on their habitat and morphology. Their respiratory systems are adapted to meet the specific demands of their environments. The three primary types of respiration in mollusks are cutaneous, branchial, and pulmonary respiration.

2023年7月31日 · Explore the different types of respiration in Mollusca, including cutaneous, branchial, and pulmonary respiration. Understand how gills and pulmonary sacs aid in the respiration process in aquatic and terrestrial molluscs.

As a consequence of living in diverse environmental conditions, the respiratory organs are modified accordingly. The respiratory organs encountered in Molluscs are mainly the ctenidia and the lungs or pulmonary sac. The outer covering of the body and mantle usually act as accessory respiratory organs.

Gill, in biology, type of respiratory organ found in many aquatic animals, including a number of worms, nearly all mollusks and crustaceans, some insect larvae, all fishes, and a few amphibians. The gill consists of branched or feathery tissue richly supplied with …

The organisms that pertain in the mollusca phylum range from snails and slugs to clams and oysters to squids and octopus, all which are invertebrates. The entire phylum consists of 85,000 extant species, making mollusks the largest marine phylum, amounting to …

Mollusca by: Liam Sypa Most molluscs have only one pair of gills, or even just one gill.They divide the mantle cavity so water enters near the bottom and exits near the top. Thier filaments contain three types of cilia, one of which drives the water current through the mantle cavity, while the other two help to keep the gills clean.

Aquatic mollusks (i.e snails, clams and squid) breathe through the gills inside their mantel cavities. But land mollusks use an adapted mantle cavity lined with blood vessels to breath "skin breathing".

Mollusca is the second largest phylum in terms of species. It is made up of over 110,000 species; most of these species are aquatic. The species in this phylum live in diverse environments which can range from arctic seas to tropical streams to high mountainsides.
