Part 2 » Foods are physically broken down into smaller pieces. » Begins when you take your first bite of food » Your teeth are the first stage in mechanical digestion by chewing, chopping into smaller bits, separating parts, moving from one place to another, or mixing parts together. » Chemicals produced by the body break foods into smaller chemical building blocks. » Begins in the mouth » When food is changed chemically; when acids, bases, and enzymes work on the carbohydrates, proteins, and fats in your food and change it into smaller molecules and deliver nutrients to your cells. » Occurs after food has been digested. » Process by which nutrient molecules pass through the wall of the digestive system into the blood » Nutrients are moved through the small intestines and then dispersed to other major organs. » Nerve and hormone regulators control the process of digestion. » The digestive system is connected to other systems. » Digestion break down food for nutrients » Respiration nutrients broken down into molecules and released to major organs » Circulation molecules help blood flow, oxygen and energy dispersed throughout the body. Carbohydrates » Provide energy for all body functions. » Are the easiest macronutrient to digest and leave the stomach most rapidly, followed by proteins than fats. » Start breaking down in the mouth » Breaks down into sugars which enters the blood stream and provides energy throughout body. Proteins » Used for growth and repair of body tissues » Takes longer to digest but once smaller particles are in the liver one of 3 things happen ˃ 1. It converts to glucose, ˃ 2. It converts to fat or ˃ 3. It is directly released into the blood as amino acids. Vitamins » help regulate body functions, build cells » Vitamins are absorbed mainly in the small intestine. » Fat is the transport for which the vitamins are delivered to the liver. Mineral » Build cells, take part in chemical reactions, carry oxygen, and serve nerve impulses. » Intestinal absorption of minerals increases when the body is lacking the particular nutrient. Fats » Store energy, help absorb some vitamins and cushion organs. » Major breakdown of fats happen mostly in the small intestine. » When foods with high lipid content enter the stomach, the hormone – gastric inhibitory peptide is released, slowing down movement flow out of the stomach. » This is why we feel full after eating high fat foods. Water » Carries other substances, enables chemical reactions, removes waste products from cells. » Saliva, gastric secretions, bile, pancreatic acids and intestinal secretions take up approximately 7 liters of water, when combined with an intake of an average of 2 liters of water ingested, the body is processing approximately 9 liters of water daily. » 72% is absorbed in the first half of the small intestine, 20% is absorbed in the lower half of the small intestine, and 6% is absorbed in the large intestine.
