NERVOUS SYSTEM The nervous system consists of the brain‚ spinal cord‚ sensory organs‚ and all of the nerves that connect these organs with the rest of the body. Together‚ these organs are responsible for the control of the body and communication among its parts. The brain and spinal cord form the control center known as the central nervous system (CNS)‚ where information is evaluated and decisions made. The sensory nerves and sense organs of the peripheral nervous system (PNS) monitor conditions

``DIFINITION The muscular system is an organ system consisting of skeletal‚ smooth and cardiac muscles. It permits movement of the body‚ maintains posture‚ and circulates blood throughout the body Muscles provide strength‚ balance‚ movement and heat for the body to keep warm There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles Skeletal muscle is a form of striated muscle tissue existing throughout the human body‚ and which

The Lymphatic System And Immunity The cells‚ tissues‚ and organs of the lymphatic system play a central role in the body’s defenses against a variety of pathogens‚ or disease-causing organisms. Acts against environment hazards‚ various pathogens‚ and internal threats. Lymphocytes (primary cell) are vital to or overcoming infection and disease. Lymphocytes respond to invading pathogens‚ abnormal body cells‚ and foreign proteins. They act to eliminate these threats or render them harmless

The musculoskeletal system includes bones‚ muscles‚ and connective tissues that all work together to provide the framework for the body‚ create body movements‚ store minerals and lipids‚ produce blood cells‚ and protest the body’s organs. The bones‚ muscles‚ and connective tissue comprise approximately sixty percent of the body’s mass. There are 206 bones and about 700 named muscles of three different types: skeletal‚ cardiac and smooth muscles (Taylor). Musculoskeletal disorders consist of minor

Respiration. *The respiratory system consists of tubes that filter incoming air and transport it into the microscopic alveoli where gases are exchanged the entire process of exchanging gases between the atmosphere and body cells is called respiration and consists of the following: ventilation‚ gas exchange between blood and lungs‚ gas transport in the bloodstream‚ gas exchange between the blood and body cells‚ and cellular respiration *The organs of the respiratory tract can be divided into two

THE DIGESTIVE SYSTEM Functions of the Digestive System • Ingestion- where in food from outside of the body enters the alimentary tract through the mouth • Digestion- which could be mechanical (physical breakdown of food into smaller pieces or chemical (enzymatic action) • Absorption of digested materials into venous circulation as well as lymphatic capillaries • Provision of nutrients to the cells of the body • Elimination of undigested materials ANATOMY AND HISTOLOGY OF THE DIGESTIVE

The Lymphatic System The Lymphatic System is very important. It helps with the Cardiovascular system‚ and our immune systems. The Lymphatic System is made up of two semi-independent parts. One is a network of lymphatic vessels. The other part is various lymphoid tissues and organs all over the body. The functions of the Lymphatic System transporting fluids that have escaped from the blood vascular system‚ and the organs house phagocytic cells and lymphocytes. Lymphatic vessels are an elaborate

The musculoskeletal system has many functions to it because it is actually two systems that are put together; muscular and skeletal. The organs that are in these systems are skeletal muscles‚ bones (joints‚ tendons‚ and ligaments). By dividing the two systems into different sections‚ it will make it easier for you‚ the reader‚ to understand and make sense of the information. The muscular system functions are to provide movement‚ protects organs‚ and production of heat. There are many muscles that
