  • Digestion - 796 Words
    When foods are eaten they must be changed into smaller molecules of nutrients before they can be absorbed into the blood. Once broken down, the nutrients are carried around the body through the bloodstream and the body uses them to build and nourish cells; and to provide energy. Food travels though the digestive tract by muscle contraction called peristalsis. This journey of digestion can take up to twenty four hours. Digestion begins in the mouth where the teeth break food down into smaller...

    Biology Form Four Digestion Digestion is the process by which food is broken down from complex insoluble substances into simple soluble substances. There are two types of digestion – chemical digestion and mechanical digestion. Mechanical digestion involves breaking up large pieces of food into smaller pieces. This provides a large surface area for the action of enzymes on food. There is no change to the chemical composition of food during mechanical digestion. Mechanical digestion occurs in...

    Scoop to Poop As I’m taking a bite of pizza, I follow it through my digestive tract. It has many stops along the way before finally being able to exit through the other end. First, it goes through my mouth to my pharynx, then to my esophagus, stomach, small intestine, large intestine, and lastly out through my anus. The first stop in the digestive tract is the mouth, or oral cavity. The mouth serves two main functions: the beginning of mechanical and chemical digestion. Chewing, or...

    DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth, with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus, which causes the food to stick together, and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland, submandibular glands, and sublingual, all...

  • Digestion - 1142 Words
    Digestion is the complex process of turning the food you eat into the energy you need to survive. The digestion process also involves creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the...

  • Digestion - 559 Words
    Digestion Essay The path of digestion begins in the mouth when food is broken down mechanically, into smaller pieces, by the teeth and tongue. The complex carbohydrates found in the food are also broken down chemically with the help of the enzyme (ptyalin), found in saliva. The food is then mixed and turned into a swallow ready material known as bolus. When the bolus is swallowed, it travels through a muscular tube known as the esophagus. It is then allowed into the stomach by passing through...

  • Digestion - 1103 Words
    The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. In addition to the alimentary canal, there are several important accessory organs that help your body to digest food but do not...

  • Digestion: Describe the digestion of a burger
    Digestion A burger is broken down mechanically by biting into it. The food in the mouth sets off salivary glands that secrete salivary amylase, which breaks down amylase in the burger. When the food is broken down enough, the tongue shapes the food in a bolus, or a ball. The bolus is pushed back to the pharynx at the back of the throat. The food stimulates the opening of the flap so the good goes down the esophagus, rather than the windpipe. Because of peristalsis, rhythmic waves created by...

  • Digestion of Starch by Salivary Amylase
    The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase, the key enzyme for starch digestion, salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose, amylopectin, and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis, pancreatic resection, pancreatic neoplasm, cystic fibrosis, and other causes of pancreatic insufficiency....

  • Ib Biology Hl2 - 6.1 (Digestion)
    6.1.1 Explain why digestion of large food molecules is essential. There are two reasons why the digestion of large food molecules is vital. Firstly, the food we eat is made up of many compounds made by other organisms which are not all suitable for human tissues and therefore these have to be broken down and reassembled so that our bodies can use them. Secondly, the food molecules have to be small enough to be absorbed by the villi in the intestine through diffusion, facilitated diffusion or...

  • Process of Digestion and Absorption after eating a hamburger.
    Process of Digestion and Absorption after eating a hamburger. After someone eats a hamburger with the works, they do not really think of what nutrients are in that hamburger, what the body does to get those nutrients out of the food, or even what process is used, they just think of how good it tasted. To get all the nutrients out of the food the human body uses processes called absorption and digestion. Some of the processes of digestion are mechanical and chemical; these are the step before...

    THE PATH OF FOOD THROUGH THE DIGESTIVE SYSTEM The process of digestion can be fast, or can take some time depending on what a person has eaten. The time frame can also be affected by the person’s activity level. Food which is taken through the mouth is initially broken down by mechanical means. The teeth are responsible for grinding food, while the tongue assists the mixing of the food with saliva, which is secreted by the salivary glands, thereby initiating the...

    The process of digestion seems deceptively simple, matter moves into the body and continues down a conveyer belt like chain of organs that break it down completely before it leaves the body. However, the maintenance of such a system is complex and relies on a balance of pH and helpful bacteria to maintain homeostasis. Both acidic and basic pH’s are required at various points in digestion to maintain balance during the process. Saliva in the mouth, the starting point of digestion, is only mildly...
