- All organisms need food for maintenance and growth. Animals obtain food in a variety of ways the Amiga in circles of food products or by extending the outer portion of its side of Plasm the enterprise them from other parts of the body flows into the extension. Stentorian has beating silly but sweet microscopic food do is opening. This Hydroid capture small aquatic animals with its tentacles. After paralyzing the animal the tentacles band in word and carry the food to the open mouth. A primary and extends its tubular pharynx to the food. Some insights such as the fruit fly. Obtain food with sucking mouth parts. The mouth parts of other insects to the food. This flesh eating mammal has large sharp teeth. Are their most grind green vegetation with Ridge done grooved to. The just Jennifer would occur is and adjusted cavities which may be fully enclosed. Have one opening. Or have two openings. The temporary food bank you walls of amoeba serve as the just of cavities that are fully enclosed. The amoeba extends to the podium about encircled a food the food with some water is taken into the under plasm as a food bank you all. Streaming movements in the end our plans and move the vacuum waltz and zines are secreted into the vacuum or where enter a cellular to gesture and proceeds the amino acids and sugars diffuse into the side of Plasm. Hydrides such as this marine policy have adjusted track with one opening before it enters the opening and the undigested food leaves through the same opening. The power form several a fiery which are larval forms these detach and develop into adult jellyfish ARMA do see. The fire also has a single opening through which proved enters and the undigested food leaves. Some of the brain shrimp clustered around the opening pass through the short got out to that adjusted cavity. In going to gestate cavity the shrimp is broken down into smaller particles by enzymes. The food particles pass through radio come out which extends from the does gestate cavity. Some of the food particles are engulfed by Emmy Boyd selves the gesture has completed in these food bank you waltz and adjusted food is this tributed throughout the organism. Undigested food is ejected through the single opening. Clarions also have a single opening that serves as mouth and anus. The opening is on the end of the tubular pharynx are proboscis which tears the brood into microscopic bits as it is sucked into that adjusted cavity. The Justin is primarily enter a cellular within back you won't have cells lining that adjusted cavity. The third type of the just of cavity has an opening at each end. And this ribbon worm they did just a tract is a silly aided to extending the entire length of the body the tube has a mouth at one end and an anus at the other. Segment it worms also having to gestate system with an opening at each end. Sense the food passes through the tract in one direction. Specialization into a variety of organs as possible each performing a particular job of storied stood gesture in or absorption. The Prost army and pushes the food into the mouth. And a muscular pharynx exert strong suction drawing the soil containing decaying organic matter into the esophagus. See Christians of special glands of the it's off again as regulate the county imbalance necessary for effective action of enzymes. They use Office forces being in just a material along and into the crop where it is temporarily story to. The muscular gizzard which contain stones. Grinds and breaks the material into small particles. The intestine the largest part of the digestive tract. Secretes in Zion switch up the just the food. Across sections of the intestine. Shows a flap like extension of the dorsal wall into the intestinal cavity. This dorsal fault provides a greater surface area for absorption of the jested food. Undigested food is pushed along through the intestine and out the anus. But it just of tract of the earthworm has a muscular to rabbits on for example the peristaltic action of the crop and gives are it helps to push the food along. Peristalsis also occurs in other organisms for example. Daphne on the peristaltic action of the smooth involuntary muscles push the food along. The justice system of the grasshopper is very similar to a bout of the earthworm the food moves in one direction only and the jest of tract has specialized muscular organs. Food is chewed by the mandibles and Max Ellie and lubricated by the sound of every glands. Get them passes through the esophagus into the large then while the crop where it is stored. The gathered grinds the food into smaller particles before it enters the stomach enzymes which are secreted into the stomach. Chemically to just the food. The intestine which consists of three parts for that adjusts and absorbs the prude the rectum reabsorbed water from its contents this reabsorption is an adaptation for water conservation. The frog has been adjusted system of a typical brought about. Food passes through the shortest often gets to the stomach where the gesturing begins. Restock tapers at the lower and and joins the small intestine at the pylorus. The proof is the jested and absorbed as it passes through the small intestine which is longer than in the smaller forms and has a folded surface the undigested food enters the shorter and broader large intestine where water is reabsorbed through its walls. It connects to the clinic. Which leads to the exteriors money abroad or Brits have excessive Rita shoes which to create the jest of juices preload liver to create bile which collects in the garb ladder and passes through the bio docked into the small intestine the major organ of the gesture and an absorption repent Korea's lies in the medicine Terry and side of the curve of the stomach it produces enzymes which pass into the upper small intestine and are just fat protein starch a nucleus assets. Been adjusted system is adapted to the feeding behaviour of the animals and the type of food it eats for example birds eat hard seeds which must be broken down. This is accomplished in the gizzard the gizzard has heavy muscular walls and contain stones which are taken in with the food. These break grain into smaller particles which are broken down further by the gestate juices. They did just of tract of mammals is very similar to about of the prog consisting essentially of a tube from one end to the other. It includes the mouth with its teeth and tongue. The Sophos. Stomach. Small intestine. SECAM. Large intestine. Rectum. And a mouse. In this living mammal peristalsis is occurring in the stomach and small intestine as into Prague the liver and pancreas equate the jest of juices along small intestine also secretes in signs and accounts for most the gesture and an absorption of food. The inner surface of the small intestine contains thousands of the lie which project into the intestinal cavity the bell I vastly increase the available surface for absorption. Thus structures that handle the process of the gesture and very considerably informed. However all animals mechanically terrible food into smaller pieces which are been chemically acted upon by enzymes.
