1. Our digestive system provides the body a means to transfer nutrition from the external environment into the cellular level in order to sustain life. Salivary glands‚ controlled by the autonomic nervous system‚ are located in the oral cavity. Its main role is to secrete saliva in the oral cavity. There are three pairs of salivary glands. Parotoid savary gland lies under the skin on each side of the mandible. These glands secrete amylase‚ an enzyme that breaks down starches. The parotoid duct implies

creating waste to be eliminated. The digestive tract (or gut) is a long twisting tube that starts at the mouth and ends at the anus. It is made up of a series of by muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver‚ gallbladder‚ and the pancreas.

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. Anatomy is the study of the human body while physiology‚ is the study of how the body functions. For example‚ the cardiovascular system includes the heart‚ veins‚ and blood.

organisms. Throughout the digestion process‚ food is broken down into small molecules‚ where it can be absorbed easily. There are many organs that aid in this complex task. Ingestion‚ digestion‚ and absorption are the three necessary steps of the digestive process. First‚ food is ingested. Ingestion takes place in the mouth. Once food enters the mouth‚ teeth chew it. The salivary glands produce saliva‚ which is mixed with food while chewing. Saliva helps break the food into smaller pieces. These
