This essay will explain the function of the respiratory‚ digestive and cardiovascular systems and how they work together to produce nutrients and oxygen to the cells for cellular respiration (energy for the body) The first system in the body is the digestive system. When food enters the mouth the salivary glands secrete saliva which mixes with the food. This makes it easy to chew and swallow. Once the food has been chewed enough the food travels down the oesophagus to the stomach. Once the food

process of converting the food you eat into nutrients that your body can use for energy‚ growth and cell repair needed for survival. The digestion process not only takes in nutrients but also eliminates the waste products from your food. The digestive system is a series of long twisted tubes that start at your mouth and goes all the way down to your anus. It’s made up of different tissues that have important functions in breaking down the food. Here is where the whole process starts‚ the mouth

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

Power Agency (MSCPA) operates a nominal 55 MW unit with a limestone forced oxidized WFGD system. It has been in operation since 1983. The absorber was a tray tower with a single tray designed for 90% SO2 removal and supplied by The Babcock & Wilcox Company (B&W). The boiler fires high sulfur eastern bituminous coal producing SO2 loadings up to 7.5 lbs/MBtu. To increase the removal in the WFGD system‚ MSCPA and B&W added a second tray in 2002 to take advantage of dual tray technology. SO2

THE PATH OF FOOD THROUGH THE DIGESTIVE SYSTEM The process of digestion can be fast‚ or can take some time depending on what a person has eaten. The time frame can also be affected by the person’s activity level. Food which is taken through the mouth is initially broken down by mechanical means. The teeth are responsible for grinding food‚ while the tongue assists the mixing of the food with saliva‚ which is secreted by the salivary glands‚ thereby initiating the chemical

contrast of a rabbit and tigers digestive systems Rabbits are herbivores that eat grass only. Rabbits can’t eat meat because it’s easier for them to digest grass. Tigers are carnivores that eat meat only. Tigers can’t eat grass because they cannot digest the food fast enough and their digestive system in the stomach is short. The digestive system of a tiger consists of an oesophagus‚ pancreas‚ mouth‚ stomach‚ small intestine‚ caecum‚ Large intestine. The digestive system of a rabbits consists of a

Diarrhea is a complication of the alimentary or digestive system‚ a complication we all have faced one time or another. Ivan Damjanov’s Pathology for the Health Professions defines diarrhea as “the frequent passage of loose‚ watery stools because of intestinal or pancreatic and hepatobiliary disturbances” (Damjanov‚ 2012). The primary reason why diarrhea occurs is due to an increase in colonic fluid volume in the intestines. The increase in colonic fluid is a result of three physiologic mechanisms
