Respiratory System
Bayani Gaba-gaba
Walk into an overcrowded broiler house near Ogbomoso at midday and you will hear it before you see it: hundreds of birds standing with beaks open, wings held slightly away from the body, breathing fast and shallow. A healthy animal's breathing is something you barely notice. A struggling one announces itself through its breathing long before anything else goes visibly wrong, which is exactly why WAEC expects you to know this system cold.
In this lesson you will trace air on its journey from the nostrils to the alveolus, the microscopic sac where the real work of breathing happens, and learn exactly how oxygen and carbon dioxide swap places there by simple diffusion. You will learn the full range of jobs the respiratory system performs beyond gas exchange, draw a sharp line between external respiration in the lungs and internal respiration inside body cells, and connect all of it to something every farmer must watch for: a rising breathing rate, a cough, or a poorly ventilated house that turns a healthy flock into a sick one.
