The pancreas is an organ located in the abdomen. It plays an essential role in converting the food we eat into fuel for the body’s cells. The pancreas has two main functions: an exocrine function that helps in digestion and an endocrine function that regulates blood sugar. Basic Anatomy: The pancreas is located behind the stomach and is surrounded by other organs including the small intestine‚ liver‚ and spleen. It is about six inches long and is shaped like a flat pear. The wide part‚ called the

pyloric. The stomach differs from other portions of the digestive tract in that it has three muscle layers used to produce a turbulent action necessary for digestion. There are multiple cell types in the stomach lining including the mucus‚ parietal‚ endocrine‚ and chief cells. The principle function of the stomach is to mix the food with digestive enzymes creating a semi-fluid mixture known as chyme. The digestive secretions in the stomach include hydrochloric acid‚ pepsin‚ intrinsic factor‚ and

Chapter 3 of Introduction to Psychology is titled "Neuroscience and Behavior" and contains three different modules. Module seven contains information on Neurons and how they function. Module eight contains information about the nervous system and the endocrine system‚ and it also explains how the body communicates from within. Module nine is the last module and contains information on the brain. The different parts and functions of the brain are also found in module nine. Module 7 Neurons are the most

The Digestive System The job of the digestive system is to break down food into substances to provide the body with vitamins‚ energy and minerals. The digestive system is approximately 20 to 30 feet and acts in stages to be able to digest the food we eat. The first stage is chewing which helps us break down small pieces of food making it easier to digest and swallow. Saliva in our mouth has special enzymes that help us break down foods like starchy foods. The second stage is swallowing

human body consists of eleven major organ systems that maintain homeostasis: the skeletal‚ muscular‚ circulatory‚ nervous‚ respiratory‚ digestive‚ urinary‚ endocrine‚ reproductive‚ integumentary and lymphatic systems. These organ systems are dependent on each other to keep the human body in homeostasis. For example‚ the nervous and endocrine systems coordinate functions of other body systems because they allow information to be communicated throughout the body. The nervous system consists of the

experiencing the following symptoms as it is your body’s way of regaining a normal temperature of 37°C. In order for the body to increase in temperature‚ it will need to have a negative feedback; the response needs to counteract the stimulus. The Endocrine and Nervous System play a vital role in maintaining homeostasis through negative feedback as they coordinate the responses in your body and help with thermoregulation. Thermoregulation is the way that the body keeps its internal temperature at a

Endocrinology is the “study of medicine that relates to the endocrine system‚ which is the system that controls hormones”. An endocrinologist is a trained professional who: monitors ‚ records and reports the wellness conditions of a patient‚ modifies patient treatment fields‚ prepares patients for examinations (gives them information and schedules appointments that lead up to the procedure)‚ supervise and manage less-skilled endocrine surgeons‚ and “diagnose problems dealing with the: thyroid‚ adrenals
