stomach‚ small and large intestine‚ and the anus. There are also accessory digestive organs involved including the salivary glands‚ liver‚ pancreas‚ and gallbladder. Digestion begins in the oral cavity where the cheeks and lips press the food against the teeth‚ a process known as mastication.

Animal Survival The need for Food There are 3 main types of food: carbohydrates‚ proteins and fats. * Carbohydrates and fats are both required for sources of energy. * Proteins are needed for growth and for repair or worn out tissues.

This means they are small enough to pass through the wall of the small intestine and to dissolve into the blood. Different mammals eat different types

storage tank where food is churned and turned into a paste called chime. Also‚ the stomach starts the breakdown of food proteins by secreting pepsin. The small intestine is the longest part of the alimentary canal and the place of most enzymatic digestion and virtually all absorption of nutrients. The small intestine shuffles the chime back and forth contacting with the nutrient-absorbing mucosa. Peristalsis propels chime through the small

A) An ulcer starts by eroding the mucosa of the GI tract wall. What functions of digestion and/or reabsorption might be lost if this layer is no longer functional? What functions will be compromised if the ulcer eats through the submucosa and then the muscularis? Some of the ingested and secreted may not be absorbed correctly and may seep lumen if the mucosa layer is no longer functional. The functions that may be compromised if the ulcer eats through the submucosa and the muscularis would be the

The Small Bowel The small intestine is divided into three structural parts‚ Duodenum‚ Jejunum and Ileum‚ it is the part of the gastrointestinal tract following the stomach and followed by the large bowel. The inner wall‚ or mucosa‚ of the small intestine is lined with project microscopic finger-like pieces of tissue called villi. Digested food is able to pass into the blood vessels in the wall of the intestine via these villi. It is the site where most of the nutrients from ingested food are absorbed
