    Digestion is a process that involves the breakdown of nutrients in order to be thoroughly absorbed by the body. The cephalic phase includes smelling, seeing, and thinking about food, which is the preparation for digestion. This is operated by the parasympathetic nervous system, which prepares the gastrointestinal tract (GI) by increasing saliva, gastric secretion, peristalsis, and the increased blood flow to the GI tract. Digestion then begins in the mouth, where salivary amylase assists with the

    1. Discuss process of ingestion, digestion, absorption, and elimination. Identify the major organs associated with each of these processes. a. Ingestion: The process of taking/eating food and it depends on the amount of the food an individual eats that gives a desire to eat. The ingestion of food start from broken down of food with teeth (buccal) cavity and saliva. The oral cavity have teeth that we use in chewing the food and the tongue that help in chewing and moving the food to the back of the

    that our bodies cannot directly receive nutrients and energy from. With the process of digestion, our bodies can break down even amounts of food. Such as glucose so that the nutrients and energy can be well extracted. Molecules that are not broken down into our bodies are then passed onto the excretory system and ejected out of our bodies. What does the process of digestion requires? The process of chemical digestion requires ingested food as it makes it way through the alimentary canal. A lot of times

  • the digestion of macronutrients

    1435 Words  | 6 Pages

    breakdown of nutrients is achieved through mechanical and chemical digestion. Mechanical digestion for all macronutrients begins in the mouth and it involves the physical breakdown of food through tearing, chewing, mixing and churning (Bowers et al., 2002). Mechanical digestion prepares the food for chemical digestion by increasing the surface area upon which the digestive enzymes can act (Bowers et al., 2002). In chemical digestion, polymers are broken down chemically through the process of hydrolysis

  • Digestion and Metabolism

    Digestion occurs in the gastrointestinal system, which is composed of the gastrointestinal tract (GI tract) and the associated accessory organs. The process of digestion occurs through six steps, namely ingestion, secretion, mixing, digestion, absorption and defecation. (Tortora & Derrickson, 2008). Anatomy of the digestive system The GI tract is also called as the alimentary canal, which is essentially a long winding tube of approximately 30 feet (9 meters). The mouth, esophagus, pharynx, stomach

    The beginning process of digestion starts as pizza enters the gastrointestinal tract through the mouth, where the oral cavities begin mechanically breaking down pizza by the cutting, ripping, and grinding actions of the teeth. As the pizza breaks down it is mixed with saliva; salvia contains salivary amylase, this converts the starches in carbohydrates into simple sugars. Therefore, as your saliva and rolling motion of the tongue turns the pizza into a soft, pliable ball called a bolus. As the bolus

    The Detail Digestion Process & Body Absorbs of Nutrients Digestion is the chemical breakdown of complex biological molecules into their component parts, i.e. lipids into fatty acids, proteins to individual amino acids, and carbohydrates into simple sugars. The functional objective is to produce various chemicals to break down the food, filter out harmful substances when possible, and get rid of solid wastes. The mechanical way the digestion works in order to change the physical form of the food is

  • Aerobic Digestion: The Final Stages Of Aerobic Digestion

    1233 Words  | 5 Pages

    The final stage of digestion is assimilation. This is when the food absorbed in the small intestine is used in the body for metabolic purposes, being transported by the blood via the capillary network surrounding the small intestine (Boyle and Senior, 2008). As previously discussed, the body requires oxygen and glucose to produce ATP and this is known as aerobic respiration (McArdle, 2015). A marathon runner relies upon this aerobic respiration to complete a marathon unlike a short distance race
