INTRODUCTION
Respiration is one of the characteristics of ALL LIVING THINGS. In the simplest terms, "respiration" simply means "breathing". But more formally, the term depends on what type of respiration been referred to. Essentially, "respiration" refers to gaseous exchange of unwanted carbon dioxide and much-needed oxygen for the body's use. In direct terms, oxygen is essential for life.
There are two types of 'respiration': pulmonary (visible breathing) and cellular (which is not visible). Regular, visible (pulmonary) respiration is simply another term for breathing - or the inhalation-exhalation process. In this process, the unwanted gas expelled is mainly carbon dioxide. This is then replaced during the inhalation breathing phase by the oxygen content within the air inhaled.
The other kind of respiration is called "cellular respiration". It occurs in the very local level of the cell itself, where a gaseous exchange takes place as unwanted carbon-dioxide is expelled through the cell walls and oxygen is diffused into the cell for energy purposes within the cell itself.
Animals in general are divided into Vertebrates and Invertebrates. Vertebrates are animals with a vertebral column or backbone and Invertebrates are animals without a backbone.
Invertebrates include organisms from the following phyla: Porifera, Cnidaria, Nematoda, Mollusca, Annelida, Arthropoda, Echinodermata, etc.
Invertebrates can be further divided into two groups according to their level of complexity and specialization. These are: 1. Lower Invertebrates: This comprises of the phyla Protozoa, Porifera, Cnidaria,
