Digestive System Diagram Online Biology Tutors Tutorpace We eat food through our mouth. As the organic nutrients are complex and insoluble ,they are first broken down into simpler soluble substances with the help of digestive enzymes and this process is called digestion. Digestion starts from the mouth .The food is processed with the help of teeth to generate particles which are small and of the same texture .Inside the mouth the salivary glands secrete saliva which contains an enzyme called salivary amylase that breaks down starch into sugar. From the mouth the food enters into the esophagus. By the peristaltic movement of the walls of the esophagus the food enters into the stomach. The gastric glands on the wall of the stomach release HCl, a proteindigesting enzymescalled pepsin and mucus .The HCl creates an acidic medium for the action of the enzyme pepsin. The mucus protects the inner lining of the stomach from theacid. The small intestine receives the secretion of the liver and pancreas. The food coming from the stomach is acidic and has to be made alkaline for the pancreatic enzyme to function. Bile juice helps in the emulsification of fats The pancreas secretes pancreatic juice which contains trypsin for digesting proteins and lipase for breaking down of emulsified fats.The wall of the small intestine secretes succus entericus which helps in the complete digestion of starch,proteins and fat. Thevilli on the wall of the small intestine absorb the digested food and the remaining undigested food reaches the large intestine. Any digested food and water present in it is reabsorbed by their walls and the undigested food enters into the rectum and temporarily stored there and is pushed out through the anus.

While the most useful phrase might be inquiring about the location of the bathroom, another great phrase to master is the equivalent of “Hello, nice to meet you.” This phrase, expressed in Spanish as “Hola, mucho gusto” is useful in any personal situation where you’re meeting someone new. You’ll come across as polite and friendly, and it’ll get the interaction started. When you’re leaving a store or other location, a nice phrase to express your gratitude and your farewell is “ ¡Gracias, adiós!” This means “Thank you, goodbye!” You can’t go wrong with using it in almost any context when you are leaving. Now that you are equipped with pleasantries to greet people upon your arrival and departure, let’s get into more specifics. At customs, or in a government office, you may have a need to state your nationality to receive the appropriate form, or indicate what language you speak. In order to communicate that you are from the United States and/or American, you can choose one of the following phrases: “Soy de los Estados Unidos” (I am from the United States) or “Soy americano/a” (I’m American â€" and end the second word with ‘o’ if you are male and ‘a’ if you are female). If you need to communicate complex things, it may be necessary to switch to English. In this case, it’s most polite to inquire if the person you are speaking with knows English rather than assuming they will be able to communicate with you in English. To ask someone if they speak English, try “ ¿Habla inglés?” Next: shopping. You will probably be quite amazed at the beautiful arts and crafts available in many Latin countries. If you are interested in purchasing something, you can ask the merchant to write the price for you. This avoids the confusion of understanding the verbal answer. Say the following: “ ¿Puede escribir el precio?” Now, the phrase that is a universal necessity: where is the bathroom? In Spanish, that’s “ ¿Dónde está el baño?” However, you can substitute the words ‘el baño’ for any other location you are looking for. So you could say, “ ¿Dónde está el mercado?” (Where is the market?) or “ ¿Dónde está la oficina?” (Where is the office?). If you need help of any kind, a very useful phrase to express this in Spanish is “Necesito ayuda.” If you are feeling ill, you can substitute ‘un doctor/una doctora’ for ‘ayuda’ to ask for a doctor. Hopefully you’ll have no need for this phrase, but it’s good to know just in case. One final tip is to learn directional vocabulary in Spanish, in case you need help finding your way around.
