Digestive system

  1. 1. Digestive System Gastric ulcer: the Possible answers are…….. Digest Stem Eyes system testis
  2. 2. The digestive system a system that is composed of organs responsible for the excretion of waste materials not the one plays the role of digestion and absorption of nutrients consists of nephrons for getting rid the toxic urea but needs the liver & gallbladder as an accessory organs. It does not composed of mouth, esophagus, stomach, small intestine & large intestine and also Amylase. Pepsin, trypsin and HCl. It is the most crucial mechanisms of the internal parameters of animals and After the integumentary system holds The most interesting topic this afternoon.

  6. 6. Mouth  First, the mouth is the place where food is taken in and where digestion begins. The mouth is adapted to receive food by ingestion, break it into small particles by mastication, and mix it with saliva.  The digestive functions of the mouth include: Chewing, grinding, and mixing of food Formation of a bolus Initiation of digestive processes Swallowing and tasting.
  7. 7. Esophagus  The esophagus itself is a muscular tube, approximately 25 cm (10 inches) from top to bottom.  There are two major muscle layers lining the esophagus. The first is an outer muscle layer and the inner layer of muscle.  The esophagus is a somewhat unique organ in that the muscle in the upper
  8. 8. Stomach  The inside of the stomach is composed of three layers, from the innermost layer to the outermost layer:  muscosa,  submuscosa,  muscularis externa,  serosa.  The primary functions of the stomach are killing bacteria and breaking down food releasing to the small intestine while maintaining a constant release rate of material from the stomach to the small intestine.
  9. 9. Small Intestines  The small intestine is where most chemical digestion takes place.  The small intestine in an adult human measures on average about 5 meters (16 feet), with a normal range of 3 - 7 meters; it can measure around 50% longer at autopsy because of loss of smooth muscle tone after death.  Needs pancreatic enzymes to digest nutrients.
  10. 10. Small Intestine
  11. 11. Large Intestine  Its function is to absorb water from the remaining indigestible food matter, and then to pass waste materials from the body.  The large intestine consists of the cecum and colon. It starts in the right iliac region of the pelvis, just at or below the right waist, where it is joined to the bottom end of the small intestine. From here it continues up the abdomen, then across the width of the abdominal cavity, and then it turns down, continuing to its endpoint at the anus.  The large intestine is about 1.5 metres (4.9 ft) long, which is about one-fifth of the whole length of the intestinal canal.
  12. 12. Large Intestine
  13. 13. The anus is an opening at the opposite end of an animal's digestive tract from the mouth. Its function is to control the expulsion of feces, unwanted semi- solid matter produced during digestion. Anus
