Up to 24 cash back In aquatic environments mollusks use tubes called siphons to bring water in and out of the body in order to obtain oxygen and give off carbon dioxide.

. Aquatic animals can breathe through different types of respiration. The following points highlight the top two types of respiration in mollusca. Young amphibians like tadpoles use gills to breathe and they do not leave the water.

A They use diffusion through their moist skin and gills in marine environments b They use gills in marine environments and primitive lungs on land. Branchial breathing This system is highly efficient in absorbing oxygen which is scarcer in water than in air. These gills are present as outgrowths to their skin which is covered by the exoskeleton.

The closed circulatory system delivers nutrients nad oxygen more quickly than an open circulatory system. Mantle cavity so water enters near the bottom and exits near the top. In this O 2 dissolved in water is used.

Most mollusks breathe through gills although some species have developed a pulmonary respiratory system. Molluscan gills or ctenidia or branchiae and. Up to 24 cash back Essentially all mollusks respire by using gills called ctenidia which bring oxygen into the body.

The proportion of undescribed species is very high. Mollusks feed through an organ called the radula which is located in the mouth and has teeth that they use to scrape the food to be ingested. The gills are located in a bilave mantle cavity.

Others may breathe atmospheric air while remaining submerged via breathing tubes or trapped air bubbles though some aquatic insectsmay remain submerged indefinitely and respire using a plastron. Horny projecting of animals including a squid Bivalvia comprise a class of marine and freshwater molluscs that have laterally compressed bodies book lung organ that has layers of respiratory tissue that is used by some terrestrial arthropods for the exchange of gases carapace the part of the exoskeleton that covers the cephalothorax cecum. Amphibian Respiration Amphibians have evolved multiple ways of breathing.

In addition they have the esophagus stomach intestine and anus. Lungs or pulmonary sac. Up to 24 cash back Respiration Aquatic mollusks use gills inside their mantle cavity.

The outer covering of the body skin and mantle usually act as accessory respiratory organs. The organs for respiration are located in the visceral mass. The aquatic organisms also have gills.

A They use diffusion through their moist skin and gills in marine environments b They use gills in marine environments and primitive lungs on land. The nephridia are commonly seen in many of the invertebrates. Water is inhaled through the ingestive siphon and is later exhaled through the egestive siphon.

Most molluscs have only one pair of gills or even just one gillThey divide the. Aquatic arthropodsgenerally possess some form of gills in which gas exchange takes place by diffusing through the exoskeleton. The mantle cavity is a space between the mantle and the visceral mass.

10 Which of the following is the correct description of respiration in Mollusks. Since aquatic arthropods and mollusks are mainly in water they use gills for respiration. Up to 24 cash back Respiratory System.

Which of these is part of the excretory system in mollusks. 10 Which of the following is the correct description of respiration in Mollusks. Up to 24 cash back Mollusks use gills as a form of resperation as well as filters for foods though it is known that most mollusk species only use their gills for breathing.

A breathing organ of fish amphibians and other aquatic animals. In aquatic mollusks these gills are very important as they are necessary for animals that breathe underwater. The number of fossil species is estimated between 60000 and 100000 additional species.

As the tadpole grows the gills disappear and lungs grow though some amphibians retain gills for life. The gills are also refered to as ctenidia. The water and food particles are absorbed through gills.

THIS USER ASKED By pumping water over their gills fish and aquatic mollusks. Most mollusks are similar to the annelids in that they both use diffusion to bring oxygen into the body. Land snails and slugs dont have gills but they use their thin mantle cavity with a large surface area covered in blood vessels.

Additionally a tongue-like organ called a radula which bears chitinous tooth-like ornamentation is present in many species and serves to shred or scrape food. Promote diffusion of oxygen. Respiration Most mollusks respire with gills which are located in the mantle cavity.

Skin appears to be the simplest type of respiratory structure encountered in Molluscs. Mollusk species that are exclusively aquatic have gills for respiration whereas some terrestrial species have lungs for respiration. The exchange of gases takes place through these gills.

Mussels can filter 5 litres of water per hour. This is sometimes called a lung but it is NOT as developed as a true lung. Gills are widely used by aquatic animals for respiration.

The surface of the respiratory structure is greatly increased to allow rapid absorption of O 2. Maintain their body temperature c. All mollusks have which type of larvae.

Keep their gill membranes moist b. Aquatic mollusks ie snails clams and squid breathe through the gills inside their mantel cavities. Amazon Luna launches with freebies for Prime subscribersAmazon Luna special offer for Prime membersTry Amazon Luna Now.
