“The plasma membrane allows fluids or gases to pass or diffuse through to specific molecules. It allows nutrients and other vital elements to enter the cell and waste materials to leave the cell. Oxygen, water, and carbon dioxide pass freely across the membrane, but amino acids and sugars are carefully regulated (University, 2015).” When thinking of an analogy for plasma membrane, what comes to mind it the stomach and digestion of food and how it reacts to food, filter foods, and separates food and nutrients. For instance, the digestive tract begins in the mouth. Chewing food starts the beginning stages of digestion. From here it goes into the small intestine. As the food passes through the GI tract it mixes with digestive juices causing large molecules to break down into smaller molecules. The small molecules then absorb through the walls of the small …show more content…
Both isolate contents from environments, both regulate the movement of materials into and out of either a cell or body, and both communicate somehow, such as the digestive tract communicates with the body telling it when it is full, sick, or hungry. Plasma membrane communicates by sending and receiving signals. Signals sent may come from the environment, or they may come from other cells (Utah, n.a.)
As far as the plasma membrane and digestive tract, the difference between the two of them is the difference in the functions. For instance, the plasma membrane has a unique bilayer. It has a custom design for each type of cell. The digestive tract, although bigger than a plasma membrane, has a complex system that has many parts to make it work properly, but it’s not as intricate as the plasma membrane functions. For instance, it works by chewing, swallowing, passing through the small intestine, then through the large intestine, where it is then turned into waste pushed out of the
