Respiratory System in Animals and Plants

•This is the taking in of oxygen (inhalation)into the respiratory organ(e.g. lungs or gills) and breathing out (exhalation) of carbon(IV)oxide and water vapour.

• Internal Respiration

• External Respiration

• Respiratory surface

• cellular respiration

•This refers to the actual surface of the body where gaseous exchange takes place e.g. alveoli in mammals and cell membrane in amoeba

• Respiratory Organ

• Respiratory Medium

• Respiratory surface

• Internal Respiration

•This refers to the environment from which the organism picks up oxygen e.g. air and water.

• Respiratory Organ

• Transport Medium

• Respiratory surface

• Respiratory Medium

This is the movement of air in the direction over the respiratory surface. This ensures the replacement of used oxygen and the elimination of waste products.

• Transport Medium

• Ventilation

• Respiratory surface

• Internal Respiration

This is the oxidation of food substances within the cells leading to the release of energy, carbon(IV)oxide, and water

• Internal Respiration

• Respiratory Medium

• Respiratory Organ

• Respiratory surface

•This refers to the organ possessed by the organism needed to pick oxygen from the environment and pass out CO2 and water vapor e.g. lungs in mammals and gills in fishes, etc.

• Respiratory surface

• Respiratory Medium

• External Respiration

• Respiratory Organ

•This is needed to transport dissolved oxygen to the various cells of the body which in turn picks up CO2 and other waste products for elimination process e.g. blood in mammals.

• Respiratory surface

They are tiny pores in the lower epidermis of leaves. Each stoma is enclosed within two bean shaped cells known as guard cells.

• Banana

• Stomata

• glucose

• Lenticels

These are breathing pores or tiny opening found in the bark of older stems.

• carbon dioxide

• Cellular respiration

• Lenticels

• Stomata

In most cells, cellular respiration takes place in the presence of oxygen and this is known as
