Gills Reports Samples For Students

Report

Glaucus atlanticus – a kind of gastropod mollusks from the unit of nudibranchs. Nudibranch called a large group of marine gastropods. These animals are related to the usual snails and slugs, but at the same time, nudibranchs have a number of unique anatomical features. For this reason, they are isolated in a special unit, which has about a thousand species. The general principle of the structure of these animals is the same as at the garden snails, the basis of body is flat foot-sole, at the anterior end of which there are stalked outgrowths - one pair carries at its ends tiny eyes, and the ...

Lab Report Comparing the Anatomy of Crayfish and Grasshopper

Introduction
The aim of the investigation is to compare and contrast the external anatomical characteristics of two classes of the Phylum Arthropoda, Class Crustacea and Class Insecta. A crayfish was used to represent the Class Crustacea and a grasshopper was to represent the Class Insecta.
Arthropods are the most abundant and diverse group of animals on the planet. The organisms in this Phyla share common characteristics which include: the body of most arthropods is covered with chitin hardened into an exoskeleton. In crustacean, the chitin is hardened by calcium. In insects, the chitin is tanned, chemically bonded with ...

Introduction:

As with all living things, fish need oxygen in order to live. Fish have specialized organs called gills that are used to extract dissolved oxygen from water. In order to be able to extract the oxygen from water fish take in water through their mouths. This water is then forced into the gills. Gills are rich in blood vessels and have very thin walls. As the water passes through them, oxygen in the water is transferred through the thin walls to the blood stream. This oxygen is then transferred to cells.

Purpose:

The purpose of the experiment is to determine ...
