Transcript of Digestive System Case Study

Disclosure 1
How does your body digest different types of foods?
Digestion involves food with digestive juices, moving it through the digestive tract, and breaking down large molecules of food into smaller molecules. Digestion begins in the mouth, when you chew and swallow, and is then completed in the small intestine. What organs are involved in the digestion process? The digestive system is made up of the digestive tract. Which is a series of hollow organs joined in a twisting, long tube from the mouth to the anus. Organs that make up the digestive tract are the mouth, esophagus, small intestine, stomach, large intestine ( also called the colon), rectum and anus. Inside the hollow organs is a lining called mucosa. Inside the mouth, small intestine and stomach the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of muscle that helps to break down food and move it along the tract. The physical and chemical changes that food undergoes
as it passes through the digestive system. The food is ground up in the mouth by the teeth (physical change). The acids in your stomach then break down the food (chemical) and it passes in the small intestine where the nurtritions are absorbed (chemical). Then, in the large intestine, water is reabsorbed into the body (physcial). The role of enzymes in these processes
Enzymes reduce the load on the pancreas. The immune system lends it's white blood cells which have stores of enzymes to aid in the digestive process. Therefore, having sufficient enzymes supports the digestive system as well as the immune system. The difference between extracellular and intracellular digestion Intracellular is inside of the cell while extracellular is outside of the cell. In Intracellular, food is broken down when it is in the cell, and nutrients are absorbed. In Extracellular food is broken down before nutrients are absorbed into cells. Why did Kim tell her brother that he was going to be sick after eating the raw pork? Raw meat has a lot of bacteria on it. You could get VERY sick by eating it without cooking it first. You could get semolina poisoning or even worms. Disclosure 2 What may have caused James to be sick, according to the symptoms? Eating the raw porkchop may have caused James to be sick. His symptoms show that he has a fever, diarrhea, and cramps. The symptoms of salmonella food poisoning include fever, nausea, diarrhea, vomiting, abdominal cramps, and pain.
Explain what effects this would have on his body. The effects he would have are diarrhea, cramps, fever, nausea, vomiting, abdominal cramps and pain. Serious complications are rare but they occur when the salmonella bacteria make their way into the bloodstream (bacteremia) the infections include, bone infections (osteomyelitis), joint infections (arthritis), infection of the sac containing the heart (pericarditis), infection of the tissues which cover the brain and spinal cord (meningitis), infection of the liver (hepatitis) lung infections (pneumonia), infection of aneurysms, and infections in the center of already - existing tumors or cysts.
