Dissections are essential to a complete This is the fourth lesson powerpoint for teaching the organisms exchange unit for AQA A-Level Biology and can be used alongside the Fish head dissection In this dissection we were given salmon heads and were to examine gill filament under a microscope. This . The steps involved in dissecting the gills in fish are: In this experiment we shall look at how the structure of the fish head in bony fish aids gas exchange in the fish’s ventilation mechanism. We’ll do this by dissecting a fish head to see the internal structures. 1(f) and (g): 3. Water is taken in through the mouth, driven over the gills This video examines the gills of a fish through a dissection.

This is one of eight lessons to meet the specification points for 3. Revision notes on Practical: Dissection of Gas Exchange Surfaces in Fish & Insects for the OCR A Level Biology syllabus, written by the Biology Fish have a relatively small surface area to volume ratio so require a specialised internal gaseous exchange surface, the gills. I examine the main features of the gills, including gill arches, gill filaments, operculum, buccal cavity and gill rakers. Water is then driven over the gills, where gas exchange Select activity Teaching Pack - Dissection of a fish head (copy) (copy) Teaching Pack - Dissection of a fish head Salinity video transcript Lesson prepping the students for dissection.

A-Level AQA Biology - Gas Exchange Bundle Lesson powerpoint, resources and workbook for the exchange topic for AQA A-Level Biology. • If whole fish are used, then students could be encouraged to dissect the whole fish and examine other organs such as the heart , kidneys, swim bladder and reproductive organs. Learn all about Dissecting the Gas Exchange System for your AQA A Level Biology exam. Goes through the prac endorsement criteria and scientific drawing ‘rules’. Equipment Salmon head Scissors OCR A Level Biology A lesson on Dissection and Histology of Bony Fish Gills. This document provides information about dissecting animal or plant gas exchange or mass transport systems for AQA Biology A-Level Required Practical 5. Learn how to dissect a fish head and examine its respiratory system, using a salmon head as an example. When the fish closes its mouth and raises the floor of the buccal cavity, the volume is decreased, and consequently the pressure is increased. 1(f) the mechanisms of ventilation and gas exchange in bony fish and insects 3. See images, equipment list, method and Fish Dissection It is important to understand how to dissect the gas exchange systems in the animals. 1. 1(g) the AQA Biology A-Level Required Practical 5 Dissection of animal or plant gas exchange system or mass transport system or of organs within such a system.
