Anatomy And Physiology Study Guide

1) Anatomy is the study of various structures throughout one’s body and how they relate to one another. Anatomy is very intriguing because it allows us to examine and study the body parts that are visible to the naked eye. There is no guessing when it comes to anatomy because study is not based on interpretation, but instead we can study by touching, seeing, and examining closely the various depths of the human body. Physiology on the other hand, is the study of how body activities are carried out in everyday life, in other words, how the various body parts function and come together as a whole. When talking about anatomy and physiology the most important thing to remember is that one does not exist independently without the other. We rely …show more content…
The various functions of the human body are dependent on how the human body is structured and developed, this in turn would explain why the specific structure of a body part would have a specific function for that area of the body. This relates to the whole course of Anatomy and Physiology because as we begin to go more in depth into the human body we realize that the organ systems in our bodies that carry out everyday functions needed for our survival are just a few organs that are made of different tissues, whose tissues consist of similar cells, this large number of cells are made of molecules, and these molecules are what are in various atoms and the body is made of seven billion billion billion atoms. Which in other words explains that we would not be able to fully understand one aspect of the human body without fully understanding the …show more content…
Ribosomes are the sites of protein synthesis. Ribosomes link amino acids together in a specific order which is specified by the messenger RNA. Ribosomes are made up of two subunits, one which reads the mRNA and the other which joins the amino acids together to form a chain. Membrane bound ribosomes attach to membranes, forming a complex called the Endoplasmic Reticulum. The Endoplasmic Reticulum is a complex system comprised of tubes interconnected and membranes which run parallel to one another enclosing fluid filled cavities. It has a continuous outer membrane and accounts for about half of the cells membranes in total. There are two distinct subunits of Endoplasmic Reticulum. The Rough Endoplasmic Reticulum, has rows of ribosomes on its external surface which synthesize proteins that are mostly transported out of the cell and the Smooth Endoplasmic Reticulum, which makes cellular products like hormones and lipids. Most body cells contain relatively little, if any, smooth endoplasmic reticulum. The Golgi Apparatus consists of stacked, flat sacs associated with various tiny membranous vesicles. The Golgi is the main “traffic director” of the cell for the proteins. It modifies, concentrates, and packages the proteins and lipids made at the rough endoplasmic reticulum that are going to be exported from the cell
