Organic chemistry is the study of “living” things—not in the same way that biology is the study of life. Rather, organic chemistry takes a look at what composes the living things, and how they’re structured. Organic chemistry breaks down living things not only into organs seen in organisms, but goes a step further to break down those organs into atoms and molecules. It focuses mainly on carbon, which is highly essential to maintaining life, and particularly zeroes in on the hydrocarbon, which is a molecule composed of hydrogen and carbon. Hydrocarbons not only compose what we’re made of, but also what we consume, including carbohydrates, proteins, steroids, fats, and more! As a matter of fact, you may be surprised to know that everyday things, such as caffeine, plastic, and paint are all composed of hydrocarbons!
The human body is a complex, highly organized structure made up of unique cells that work together to accomplish the specific functions necessary for sustaining life.
The biology of the human body includes
Physiology (how the body functions)Anatomy (how the body is structured)Anatomy is organized by levels, from the smallest components of cells to the largest organs and their relationships to other organs.
Gross anatomy is the study of the body’s organs as seen with the naked eye during visual inspection and when the body is cut open for examination (dissection).
Cellular anatomy is the study of cells and their components, which can be observed only with the use of special techniques and special instruments such as microscopes.
Molecular anatomy (often called molecular biology) is the study of the smallest components of cells at the biochemical level.
Anatomy and physiology change remarkably between fertilization and birth. After birth, the rate of anatomic and physiologic changes slows, but childhood is still a time of remarkable growth and development (see Physical Growth of Infants and Children). Some anatomic changes occur past adulthood, but the physiologic changes in the body’s cells and organs are what contribute most to what we experience as aging (see Changes in the Body With Aging).
This course is designed to improve students' conversation skills in a scientific- or engineering-oriented setting. Grammar, writing styles and speaking skills specific to students' scientific and engineering areas of interest will be the focus of this course and will be accomplished through discussions of various authentic technical-based texts.
