Differentiate between a) absorption and assimilation b) canines and premolars c) ingestion and egestion ?
Answers
differentiate between:
a)absorption: Absorption is taking simple molecules, which were produced as a result of digestion into the body (blood stream/lymph) from the intestinal cavity.
assimilation: Assimilation is making new compounds from the absorbed molecules, which are necessary for normal cell functioning or to produce energy.
b)canines: In mammalian oral anatomy, the canine teeth, also called dog teeth, fangs, cuspids or (in the context of the upper jaw) eye teeth, are the relatively long, pointed teeth. They can appear more flattened however, causing them to resemble incisors and leading them to be called incisiform.
premolars: The premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps.
c) ingestion: ingestion is the consumption of a substance by an organism. In animals, it normally is accomplished by taking in a substance through the mouth into the gastrointestinal tract; such as through eating or drinking. ... Ingestion is a common route taken by pathogenic organisms and poisons entering the body.
egestion: Egestion is the act of excreting unusable or undigested material from a cell, as in the case of single-celled organisms, or from the digestive tract of multicellular animals.

Explanation:
a) absorption and assimilation
Absorption is taking simple molecules, which were produced as a result of digestion into the body (blood stream/lymph) from the intestinal cavity. Assimilation is making new compounds from the absorbed molecules, which are necessary for normal cell functioning or to produce energy.
b) canines and premolars
The first premolars role is similar to that of canines. Though not as sharp as canines, they help in tearing of the food. With two cusps at the crown, they also help in gripping the food when chewing. The secondary premolars are located behind the first premolars and molars.
c) ingestion and egestion
The main difference between ingestion and egestion is that ingestion is the intake of food into the body whereas egestion is the elimination of wastes out of the body. Ingestion occurs through the mouth in animals. ... The elimination of wastes of the digestion occurs through the anus in animals.
