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.
