Cell biology explains the structure, organization of the organelles they contain, their physiological properties, metabolic processes, signaling pathways, life cycle, and interactions with their environment. This is done both on a microscopic and molecular level as it encompasses prokaryotic cells and eukaryotic cells.
Small Intestine. Digesta passes from the stomach into the small intestine. The small intestine is approximately 28% of the horsesâ digestive tract, is 15-22m long and has a volume of 55-70 litres. This is the major site of digestion in the modern performance horse.f the horse is fasted, it will take 24 hours for the stomach to clear. It has long been a question as to what you should feed a horse first, grain or hay. Because of their density, grains tend to stay in the stomach longer, but it has not been proved to be advantageous to feed either first.
Comparatively, the length of the human digestive system is about the same as the height of a typical two-story house. Another basis for comparison is that if the average man is about 6 feet tall, the digestive system is as long as five men, or the length of a first down in football, which is 10 yards. The small intestine is the largest part of the digestive system at about 20 feet long, which is about as long as a very tall giraffe.
