This document discusses respiration in various organisms. It introduces respiration as the lifelong process of inspiration of oxygen and expiration of carbon dioxide. It then describes the respiratory organs and processes of 5 organisms: earthworms breathe through their skin, cockroaches through trachea and spiracles, scorpions through book lungs, fish through gills, and frogs through skin, lungs, or as tadpoles through external gills. The document provides details on gas exchange and respiratory structures in each organism.

- 3. WELCOME…
- 5. INTRODUCTION : IT IS A life long PROCESS OF INSPIRATION OF OXYGEN AND EXPIRATION OF CARBONDIOXIDE… IT IS PRESENT IN ALL ORGANISM…
- 6. 1. EARTHWORM SKIN IS THE RESPIRATORY ORGAN. PRESENCE OF MANY BLOOD CAPILLARIES IN THE SKIN. OXYGEN FROM THE ATMOSPHERE DIFFUSES INTO BLOOD. CARBON DIOXIDE FROM THE BLOOD DIFFUSES OUT TO THE ATMOSPHERE.
- 7. 2. COCKROACH RESPIRATORY ORGAN IS TRACHEA. OPENING ARE NAMED SPIRACLE. AIR PASSES INSIDE AND OUTSIDE THROUGH SPIRACLES. NO ROLE OF BLOOD IN RESPIRATION
- 8. 3. SCORPION RESPIRATION THROUGH BOOK LUNGS. IT APPEARS LIKE THE PAGES OF A PARTIALLY OPENED BOOK. VENTRAL OPENENING APPEAR SLIT LIKE APERTURE KNOWN AS SPIRACLE. BOTH INTAKE AND RELEASE OF AIR THROUGH SPIRACLE
- 9. 4. FISH RESPIRATORY ORGAN GILLS. GAS EXCHANGE THROUGH THE BLOOD CAPILLARIES IN THE GILL PHILAMENT. GILLS ARE SITUATED INSIDE GILL CHAMBER. FISH GET OXYGEN FROM WATER.
- 10. 5. FROG AN AMPHIBIAN. SKIN AND LUNGS ARE THE RESPIRATORY ORGAN. THREE METHODS OF RESPIRATION. 1. CUTANEOUS RESPIRATION. 2. BUCCAL RESPIRATION. 3. PULMINARY RESPIRATION. TADPOLE RESPIRES THROUGH EXTERNAL GILLS.
