Mammalian defence against infectious disease can be non-specific‚ otherwise known as innate‚ or specific (adaptive). Non-specific defence can be further categorised into external (preventive) or internal (defensive). Innate defence can be physical‚ chemical or biological. The skin‚ commensal organisms (e.g. bacteria)‚ mucous membranes and hair contribute to the physical mechanism of the body’s non-specific defence against disease. These prevent disease from entering the mammal’s body by acting

Welcome to the Fantastic Voyage! Now that we have successfully been shrunk and injected into the patient’s femoral vein‚ let me explain what our journey will entail. The first destination will be the lower lobe of the right lung. The patient’s immune system has been fighting an evil invasion of bacterium in the lung‚ and it is our assignment to document the battle. Once we have witnessed the patient’s immune system in action‚ we will head across the alveolar membrane and onward out the nose. Let

Epidemiology – the science that studies when and where diseases occur and how they are transmitted. CDC‚ Atlanta‚ tracks and traces diseases.

The organ systems of the human body are interdependent because one organ of the connects to another organ system. Organs are made up of tissues which that work together to keep organism‚ in this essay humans‚ alive. One function of a system always leads to another systems function. If one organ becomes ineffective/damaged‚ then that person may not function well and end up passing away. There are eleven organ systems within the human body: integumentary‚ skeletal‚ muscular‚ nervous‚ endocrine‚ circulatory/cardiovascular

Current Status of Malaria Vaccinology In order to assess the current status of malaria vaccinology one must first take an overview of the whole of the whole disease. One must understand the disease and its enormity on a global basis. Malaria is a protozoan disease of which over 150 million cases are reported per annum. In tropical Africa alone more than 1 million children under the age of fourteen die each year from Malaria. From these figures it is easy to see that eradication of this disease

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
