the pancreas is called the head‚ the middle section is called the body‚ and the narrow end is called the tail. The pancreas has "exocrine" cells that produce juices to help digest food; and‚ "endocrine" cells that produce hormones‚ such as insulin and glucagons. These help control blood sugar levels‚ and help the body use and store energy from food. About 95% of pancreatic cancers begin in exocrine

Understand how homeostatic mechanisms operate in the maintenance of an internal environment Homeostasis is keeping the body balanced to allow cells to function‚ despite external environment. Homeostasis is important because the cells‚ blood and tissue fluids can change by slowing down or even stop a vital chemical reaction. Its aim is to keep the body to stay the same‚ at a normal condition. Negative feedback is when change is detected; there are steps when change is detected to get it back

ASU BIO 100 Exam 4 Practice Questions 1. Because of evolutionary descent‚ many species share characteristics with other species to which they are related. Indeed‚ according to evolutionary theory‚ all living species are descended from some common ancestor in the ancient past. What evidence supports this conclusion that ALL living species are related to each other? Shared traits in the fossil record; Genetic Code; DNA Structure of all living organisms 2.

carbohydrates‚ fat and protein which should be centered on the right ’zone’ (40: 30: 30). Carbohydrate produces insulin which tells body to store the excess carbohydrates into fat. While protein produce glucagons that urges the body to use the excess carbohydrates stored in your body. So by eating a balanced zone of 40:30 carbohydrates and protein your body will have balanced insulin and glucagons which in turn will make you lose fat. The author said that eating fat actually does not make you fat while
