Purpose The digestive system prepares food for use by hundreds of millions of body cells. Food when eaten cannot reach cells (because it cannot pass through the intestinal walls to the bloodstream and‚ if it could would not be in a useful chemical state. The gut modifies food physically and chemically and disposes of unusable waste. Physical and chemical modification (digestion) depends on exocrine and endocrine secretions and controlled movement of food through the digestive tract. Mouth Mouth

Nervous System Review Sheet 1. List three functions of the nervous system and give a specific example of each. • Reception of stimuli from environment (internal or external) and relay of info to CNS (Sensory division of PNS) – e.g. Receptors in your ear send a signal to the brain when the bell rings. • Integration of stimuli to decide on a response (CNS) – e.g. Your brain receives the signal that the bell is ringing‚ along with signals from your eyes that tell you it is time for class

The Respiratory System The human respiratory system plays a very important part in our bodies. Without it‚ we wouldn’t be alive! We need air to move through our bodies at all times. Breathing‚ is a key necessity for life. Our respiratory system is made up of many organs that all work together. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide. The respiratory system organs all work together‚ like a engine in a car‚ they all have a important role. Some

Skeletal muscle is a voluntary muscle‚ this means that it is under control by the somatic nervous system. When viewed under a microscope the appearance of this muscle is striped/ striated. “The primary function of the skeletal muscle is to produce fine movements to keep you alive. Skeletal

skeletal system is divided into 2 divisions : the AXIAL SKELETON and the APPENDICULAR SKELETON. the axial skeleton consists of your SKULL‚ HYOID BONE‚ and VERTEBRAL COLUMN. and then your APPENDICULAR SKELETON consists of your SHOULDER GIRDLE‚ UPPER EXTREMITIES‚ and LOWER EXTREMITIES. your skull is the superior portion of your axial skeleton‚ wherein you can find your frontal bone‚ that forms the anterior third of your cranial dome‚ parrietal bone‚ that forms the middle segment of the cranial dome

URINARY SYSTEM This system consists of the KIDNEYS‚ URETERS‚ URETHRA‚ and BLADDER. Not many structures‚ but very important. Functions: 1. Regulate electrolytes (K‚ Na‚ etc) in body 2. Regulate pH in blood 3. Regulate blood pressure 4. Regulate blood volume 5. Removing metabolic wastes (chemicals produces by chemical reactions in the body are excreted). This is the least important of the kidney’s functions. You can survive for a few weeks without excreting waste products in the urine‚ but hour

The principal structure of the digestive system is an irregular tube‚ open at both ends‚ called the alimentary (al-i-MEN-tar-ee) canal or the gastrointestinal (GI) tract. In the adult‚ this hollow tube is about 9 meters (29 feet) long Think of the tube as a passageway that extends through the body like a hallway through a building. Food must be broken down or digested and then absorbed through the walls of the digestive tube before it can actually enter the body and be used by cells The teeth

1 Introduction The word system is derived from the Greek word "Systema" which means an or- ganized relationship among functioning units or components. System analysis is a structured approach to problem solving that breaks down a system into its compo- nent pieces to determine how these component work together by interacting with each other to achieve their purpose. Descartes emphasised that a problem under consideration should be divided into as many parts as possible and then examined
