Biology is the study of life. As we’ve learned, this field covers a broad scope of subjects. As you progress through this course, you’ll gain the knowledge you need to make informed decisions. Let’s think back to the articles Cristina encountered at the beginning of this module: how could a knowledge of biological principle help with her understanding of each article?
Think about It
Cristina read an article about some of the world’s weirdest animals. What biological principle would help her understand why these animals have the features they do?
Cristina also found an article about a “new” organ called the mesentery. How could scientists just now be discovering a new organ?
Clarifications of the mesenteric anatomy have facilitated a clearer understanding of diseases involving the mesentery—which include malrotation and Crohn’s disease (CD). In CD, the mesentery is frequently thickened, rendering haemostasis challenging. Some authors say that CD is mainly a mesenteric disorder that secondarily affects the GIT and systemic circulation.
As scientists researched the mesentery more and more, they found that it should be reclassified as an organ. As we will see in the chapter “Body Systems,” having a better understanding of bodies can dramatically improve our ability to detect and prevent illness.
