Body Systems and Disease Study Guide Skeletal system - To support the body; to give the body shape; to work with the muscles to move the body The skeletal system is made up of bones. Muscular system - To maintain body temperature; to help the body move; to maintain posture * Skeletal muscle – Voluntary; attached to the bones * Smooth muscle – Involuntary; controls movements within the body; makes up the stomach * Cardiac muscle - Involuntary; makes up the heart Integumentary system – To cover and protect the body * Skin - functions to cover the body, prevent water loss, and protect the body from infection. Circulatory System - transports oxygen and other nutrients to cells, circulates blood through the body * Heart - A muscular organ in the center of the chest that pushes blood throughout the circulatory system. * Blood vessels – tubes that carry blood throughout the body o Artery - A blood vessel with strong walls that carries blood away from the lungs. o Capillary - A narrow blood vessel that connects arteries with veins. o Vein - A blood vessel that carries blood back to the lungs. Respiratory System -exchanges gases between the body and the external environment (brings in oxygen, removes carbon dioxide) * Trachea - A tube that carries air from the throat to the lungs. * Lungs - Two large organs located in the chest and are the main organs of the respiratory system. * Bronchi - The two large air tubes leading from the trachea to the lungs that convey air to and from the lungs. * Diaphragm - A muscular wall that expands and contracts the chest when you breathe. Digestive System - breaks down food into nutrients the body can use and disposes of solid waste. * mouth – chemical and mechanical digestion take place here * esophagus – carries chewed food to the stomach * stomach – chemical and mechanical digestion take place here. * small intestine – most of the chemical digestion takes place here; where nutrients are absorbed * large intestine – Water is removed from the undigested food. * rectum – stores solid waste * liver – produces bile * gallbladder - stores bile * pancreas – produces digestive juices Urinary System - filters cellular wastes, toxins, and excess water from the body. * Kidney – Remove wastes and extra water from the blood to form urine. * Ureter – A tube that transports urine from a kidney to the bladder. * Bladder – A sac-like organ that stores urine. * Urethra – A tube that carries urine from the bladder to the outside of the body. Nervous System - detects and responds to changes in the environment; transmits information throughout the body. * Brain – The main organ of the central nervous system. Controls and coordinates most of the body’s activities. * Spinal cord – A bundle of nerves that runs down the center of the back through the vertebrae which protects it. * Peripheral nerves – A network of nerves that branch out from the spinal cord and connect to the rest of the body. How the body systems work together: * The urinary and digestive systems work together to bring food into your body and remove waste. * The urinary and circulatory systems work together to clean blood and remove cellular waste. * The circulatory and respiratory systems work together to remove carbon dioxide and supply oxygen. * The digestive and circulatory systems work together to ensure that nutrients get to the cells of the body. * The skeletal and muscular systems work together to help the body move.
