provide energy to body cell. The metabolism is tied to the respiratory system because the system is responsible for providing oxygen in our body. Digestive System The digestive system functions in a way which is firstly ingestion (in taking food)‚ digestion (breaking down the food)‚ absorption (extracting the nutrients from food) and finally defection (waste of food). The digestive system is a group of organs that breakdown the chemical components of food‚ with fluid (digestive juices) into tiny nutrients

3. How does the digestive system assist in maintaining the water balance in the body? The large intestines help with water retention so the body doesn’t get dehydrated very easily. 4. How do enzymes assist the process of digestion? Enzymes help assists the process of digestion by breaking down specific macromolecules and speeding up the process as well. 5. How do factors such as temperature‚ pH and concentration of enzyme or substrate affect the rate of enzyme-catalyzed reactions? They can speed

should be able to carry on a short conversation while doing aerobic exercise. If you are gasping for air while talking‚ you are probably working anaerobically. Aerobic exercise improves long-term endurance while anaerobic exercise improves short-term endurance. Dance tends to use mostly anaerobic activity during technique classes and exercise. Performing repetitive movements will improve muscular endurance. In some circumstances‚ choreographers include vigorous demands on dancer’s aerobic endurance which

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

The pancreas is a gland that releases digestive juices and digestive hormones. The digestive juices consist of enzymes and bicarbonate. The enzymes help break down fats and calcium in foods. The bicarbonate that your pancreas releases neutralizes the stomach acids. The pancreas is part of the endocrine system

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

is essential in the human diet to help exercise the muscles of the digestive tract. An adequate amount of fiber in the diet has been shown to reduce the risks of colon and rectal cancers HOW DOES FIBER WORK ?? Fiber affects the rate of digestion of foods‚ the absorption of nutrients‚ and the movement of waste products (stool) through the colon. It also provides a substrate for beneficial intestinal bacteria. Dietary fiber includes water-soluble and insoluble types‚ which have different
