Answers
Answer:
1 Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts.
2 The purpose of the large intestine is to absorb water and salts from the material that has not been digested as food, and get rid of any waste products left over.
3 Ruminant stomachs have four compartments: the rumen, the reticulum, the omasum and the abomasum. Rumen microbes ferment feed and produce volatile fatty acids, which is the cow's main energy source. Rumen microbes also produce B vitamins, vitamin K and amino acids.
4 The basic processes involved in the nutrition include:Ingestion: Amoeba takes in its food through this process. Initially, it pushes out its pseudopodia so that it can encircle the food. After this, it engulfs the food, thus forming a bag-like structure called food vacuole. The process is known as “phagocytosis.
5 Avoiding simple sugars, and implementing daily gentle tooth brushing and flossing is the basic foundation. Additionally, not smoking, drinking plenty of water, and getting regular dental cleanings and checkups are needed to keep gums healthy and teeth cavity free.
