Circulatory System
Akopọ
Press a finger against the gum of a healthy goat and the pink returns almost at once. Do the same to a goat heavy with barber's pole worm and the gum stays pale, sometimes almost white, because there is barely enough blood left to colour it. That single check, used by herders across Nigeria long before it had a name, is a direct reading of the circulatory system: the blood, the heart that drives it, and the vessels that carry it to every living cell in the body.
In this lesson you will learn what blood is actually made of and what each component does, how the four-chambered heart works as a double pump, and why farm animals run a double circulation, one loop to the lungs and one loop to the body, rather than a single loop. You will finish able to read pale gums, a racing pulse or a bleeding wound the way an experienced stockman does: as signals from a system you now understand.
