Introduction:
The smoke of cigarette is a complex mixture of chemical compounds bound to aerosol particles or present free in the gaseous phase. The particulate phase poses the risk for cancer, cardiovascular disease, and heart disease. Acrolein and acetaldehyde are respiratory irritants; and cyanide, arsenic, and the cresols were the primary sources of cardiovascular risk. Other chemical classes of concern include other metals, N-nitrosamines, and polycyclic

- Draw a clearly labeled diagram of the human digestive system .arrow_forwardA. What is/are the primary role(s) of the large intestine? a. to complete enzymatic digestion and store indigestible material b. to initiate enzymatic digestion of carbohydrates and to store water c. to absorb water from digested material, with essentially no digestive role of its own d. to secrete water into the material that is left over after all available nutrients have been absorbed e. to digest fats A. In the intestine most nutrients are absorbed regardless of whether the body has an immediate need or shortfall of them; ie there is little control over amounts taken up – which of the following does not follow this rule? a. absorption of sodium b. absorption of water c.absorption of iron d. absorption of fat soluble vitamins e. none of the above follow this rule – close control is exerted over all of themarrow_forwardDesign an experiment to test the hypothesis that intestinal bacteria areessential to nutrient absorption in mice.arrow_forward
- Can you help me the name of the label of all the number of the digestive system model?arrow_forwarda) What is the general function of all enzymes that are involved in the digestive process.b) Use the Table below to summarise the function of 6 named digestive enzymes that are either secreted from specific regions of the gastrointestinal system, or part of the intestinal brush border. Enzyme Site of secretion / Action Function (to include substrate and product formed)arrow_forwardCompile a table showing the components of the digestive tract, importance and features that allow each part to function efficiently.arrow_forward
- Predict some possible consequences of highdose, intravenous (IV) antibiotic administrationon the homeostasis of a person’s digestivefunction.arrow_forwardExplain the relationship between the structure and function of the various components of the digestive system. Link the structure with the function.arrow_forwardDiscribe in details each parts of the human system related with digestive system and it's each individual function starting from mouth to rectum . Also explain the process of digestion. (Include all the enzymes produced) explain in details.arrow_forward
- How does gastrointestinal tract evade dehydration? 1) Alternating wave-like contraction and relaxatio of the oral (mouth) muscles reabsorbs water which will be transported to the urinary system 2) water is an important digestive enzyme in the stomach. 3) Normal peristaltic movements in the large intestine ensure reabsorption of water that will be delivered to the circulatory system. 4) the water we drink will be mostly absord by the blood vessels attached to the esophagus and stomach. Skip questionarrow_forwardWith the two menus provided, answer the question below: Menu 1: Roasted chicken with mashed potatoes (mostly proteins and carbohydrates) Menu 2: Pasta with alfredo saude and cheese (mostly carbohydrates, dairy products and lipids) Question: Describe the steps in the chemical digestion of the main constituents of your meal (name the enzyme (s) and other secretions involved, and what cells secrete them), all of that from the beginning to the end of digestion.arrow_forwardThere are several processes that take place from the moment food enters our mouth until it is completely digested and used for energy. Using approximately 400-500 words, describe in detail and in order of process the mechanical (stomach and intestine)and chemical (gastric acid and enzymes) digestion of eating a grilled chicken sandwich with mayonnaise, lettuce, and tomatoes. Note what role the pancreas, gallbladder, and liver play in digestion of the ingredients? From what ingredients is your body deriving its energy and how many basic calories from the macronutrients ingested? Include at least two scholarly references (using APA formatting and style) to guide your answers (note that you can use your textbook as one of your references).arrow_forward
