In the beef cattle diet, common roughages include hay, silage and grass. Silage is a crop that has been preserved in a moist, succulent condition by partial fermentation in a tight container (silo) above or below ground. The majority of the food cattle eat comes from this type of feedstuffs.
Birds (some dinosaurs) and mammals have a four-chambered heart. The ventricle is divided by a septum into two compartments completely separating oxygenated from deoxygenated blood and delivering the maximum amount of oxygen to the head and body at the most efficient pressure.
What does the septum do? A: The interventricular septum divides the left ventricle from the right ventricle, thus keeping oxygenated blood from mixing with deoxygenated blood. Without this separation, the body would not be able to obtain the level of oxygen it needs for subsistence. The septum also contributes to the heart's shape and structure.
