Carbohydrates Lab Report

Glucose is a form of energy derived from carbohydrates. All living organisms requires energy to live and thrive. When glucose is ingested it is transported through the circulatory system by the various tissues and organs. This glucose will be used by the muscular and nervous system to complete day to day task. If the body is not in need of glucose it will be stored in the form of glycogen for a later date. The entire process starts with carbohydrates, for this paper we will be tracing the path of glucose starting with ingestion to the planter surface of the right foot. The glucose we are ingesting starts for example as a bowl of fruit.
As the fruit enters the mouth it is broken down into smaller particles by the teeth so that digestion can
The tongue a muscle of the oral cavity pushes the now broken down carbohydrates to the back of the throat where it can be swallowed. Food from the mouth that has been broken down and swallowed then moves from the mouth to the stomach through the esophagus. Once in the stomach the body secretes pancreatic juices that aid in the breakdown of the now digested food. These juices break the food down on a chemical and molecular level into fats, proteins, and carbohydrates. The pancreas also releases insulin a blood sugar regulator. During this absorption, the body will determine how much glucose is needed and how much needs to be stored. The stored glucose will be transported to the liver to be stored as glycogen until it is needed by the body for example (during exercise). The glucose that will be used by the body along with other proteins and fat molecules are then transferred from the stomach into the small intestines. In the small intestines are small structures called villi, villi increase the surface area of the small intestines and help with absorption while the food in passing through the small intestines. Try to imagine the villi as little obstacles the food particles must maneuver around. Active transport of these particles is the main function of the villi and the small
The blood passes from the right atrium through the right AV valve into the right ventricle. Upon contraction, the blood is forced from the right ventricle through the pulmonary valve to the lungs via the pulmonary arteries. The blood reaches the lungs where it will be package with oxygen. This now oxygen and glucose rich blood with leave the lungs on its way back to the heart by the pulmonary veins. The left and right pulmonary veins into the heart at the left atrium. In the left atrium, the blood passes through the left AV valve also known as the bicuspid valve into the left ventricle the last stop for the blood in the heart. As before upon contraction the blood is forced from the left ventricle through the aortic valve into the ascending aorta. Because our goal is to trace the blood to the right planter surface of the foot we know that the blood with continue through the aortic arch until the aorta starts to descend behind the heart. The descending aorta will turn into abdominal aorta. The abdominal aorta descends through the body until branching off into the left and right common iliac artery. The glucose and oxygen rich blood will enter the right external iliac artery from the right common iliac. From the right external iliac the blood flows distally through the popliteal artery. The blood from the popliteal artery then splits into an anterior and posterior tibial artery. The tibial artery gives rise to
