Digestion

then to the large intestine. 2. How long does the food remain in each segment of the digestive tract and what physiological processing takes place during this time? • Chemical and mechanical digestion begins in the oral cavity. Temperature, taste, texture are sensed, and the saliva helps the chemical digestion because it is secreted by the salivary glands. The breakdown of the enzymes in the saliva helps the food to be swallowed. The mechanical breakdown of the food is from the teeth, and when…

as you are swallowing it? Have you thought about where it goes, or what is going on inside your body as you digest? The term is called digestion. Digestion is the breakdown of food we eat, and turn the food into small, tiny, components that is absorbed through our bloodstream. When digestion your food it goes through two breakdowns; Mechanical, and Chemical digestion. But what happens once the food enters your bloodstream, and breakdown into small molecules? The term is called the digestive…

can enter the blood stream. In order for these foods to be broken down three separate digestions must take place. The three digestions are mechanical digestion, enzymatic digestion, and hydrochloric digestion. Mechanical digestion includes various functions in the oral cavity such as chewing, and also functions in various organs such as the stomach and intestines. The second type of digestion, chemical digestion, is involved in the breaking down of foods by…

with lagomorphs such as rabbits and a variety of rodents who practice caecotrophy. Caecotrophy, also known as coprophagy, is the act of eating soft excretions, known as caecotrophs, directly from the anus for additional nutritional absorption and digestion of plant fibers (Halls, 2008). Although strange, and seemingly unhygienic, to humans, rabbit owners must allow the behavior of coprophagy because it promotes proper nutrition for companion rabbits. The phenomenon of coprophagy is performed at…

endocrine system control with the digestive system, advanced technology and diseases that such advanced technology can be used to cure. The digestive system has two main functions; nutrients needed for humans and discarding the waste from the body. Digestion extracts the nutrients needed from the food. The nutrients are used for energy, growth and cell repair. This happens in the Upper GI (Gastrointestinal) tract; the extraction of waste happens Lower GI (Gastrointestinal) Tract.…

and molars, cusps on teeth. The salivary glands produce saliva and the enzymes in the saliva contribute to the breaking down of food through chemical digestion. Similarly, the sharks mouth is composed of teeth and tongue, but sharks do not have salivary glands. Since sharks’ swallow food as a whole or as large pieces, very little mechanical digestion happens in the mouth. So, the teeth and tongue are basically useless regarding the digestive aspect of a…

digesting of food absorbing of nutrients Dog's digestive systems work differently to that of a human, for instance the digestion process begins in the stomach for dog's and in the mouth for humans. It is important for owners to have some idea of how the digestive system works in dog's so they can look out for symptoms that may signal the dog is unwell. The process of digestion begins after the food has passed through the mouth and traveled down the esophagus. The food then enters the…

chemical changes in nature but also in our bodies? If not, I’m here to tell you all about it. Put on your seatbelts & join me in the drive through the digestion of your, rather large, pretzel stick. In your head, think about where digestion first occurs. Did you choose the stomach? If you did, sorry but you’re wrong, the correct answer is the mouth. Digestion starts with that first pretzel stick you…

water to cover the gills without getting inside the body. Digestion: Digestive track includes mouth, oesophagus, stomach, intestine and anus. It has two stomachs - The cardiac stomach is where the food is stored, where as the pyloric stomach is where most of the digestion occurs. It churns the food for mechanical digestion and uses digestive glands located either side of the stomach, producing digestive enzymes for chemical digestion. The food then passes through the antennal gland, which is…

The oral cavity is responsible for the mechanical break-down of food. As food enters the mouth, the teeth begin to chew and the tongue moves the food around. The food particles mix with saliva, which contains digestive enzymes, and becomes slippery. This enables the food to become easier to swallow, allowing it an easier passage as it move into the pharynx, esophagus, stomach, intestines, and finally the colon, which allows it to be evacuated from the body through the rectum. The oral cavity is…
