WEEK 1: AN INTRODUCTION TO HUMAN ANATOMY & PHYSIOLOGY 1. Define the terms anatomy and physiology‚ and explain their relationship using an example of a human structure with its corresponding function. The term anatomy refers to the structure and relationship of body parts such as tissues and organs. Physiology on the other hand is how these structures work as in individual and in the body as a whole. Take the circulatory system for example. The heart itself‚ blood vessels and blood

which carries the food from the throat to the stomach. Your tongue and roof of mouth are in charge of pushing the food into your throat. The esophagus is the extending tube that pushes foo through to the stomach. The contractions are called peristalsis. Right before the opening of the stomach is the lower esophageal sphincter. It allows food to pass into the stomach and closes it to make sure it does not come back up. The next stops are the stomach and the small intestine. The stomach’s muscular

The tongue helps turn food in the mouth and mix with the saliva in the mouth which contains salivary amylase enzyme. It then passes through the esophagus to the stomach which is a mixer and grinder of food. The stomach secrets Hydrochloric acid and enzymes that are used in the breaking down of the food. The food then leaves the stomach in form of a liquid or fluid into the small intestines where it is now absorbed into the system. The absorption

is your wind pipe. As mentioned before the epiglottis prevents food from entering here. 7 Lower Esophageal Sphincter The lower esophageal sphincter closes once the food has passed. It also ensures that different stomach acids do not go back up into the esophagus. 8 Stomach The stomach on an average holds up to four cups of food (this can vary from person to person) (Wardlaw‚ Smith (2009). In these walls the food is prepared for the

The stomach is large two-chambered sack. The yellow glands are on each side of the stomach. An intestine is joined to the stomach and goes along the abdomen to the anus.

The three sections of the large intestine are the cecum‚ colon‚ and rectum. Bacteria is present in the cecum to break down roughages. Fecal balls are formed in the colon. The functions of the digestive system are digestion‚ absorption‚ and elimination. A non-ruminant herbivore is an animal that has a simple stomach and is a plant eater. Bile

The reason this causes heartburn is if we do not have enough acid being produced in the stomach‚ our bodies will not send the signal to our brains that we need to close the esophageal sphincter at the top of the stomach. When this stays open‚ digestive acids can wash back up the esophagus‚ causing pain and discomfort. If you experience
