The two major arms of innate immunity are inflammation and phagocytes. Inflammation is the warning system that alerts the rest of the immune system that something is wrong, while phagocytes are the infantry of our immune system whose job is to clean out whatever is causing the infection.…

White Blood Cells (Leucocytes) Lymphocytes – some secrete antibodies, some kill infected cells and control aspects of immunological process. Monocytes – engulf bacteria. Granulocyte – 3 types; neutrophil, eosinophil, basophil, Some engulf bacteria, others involved in allergies and inflammation. Platelets for clotting. Can be sticky.…
4. Explain what is meant by “systemic infection” and “localised infection”? Systemic infection affects the whole body and causes systemic symptoms, like muscle pains, fever and nausea but with Localised infection, it limited to one or few body parts and presents with localised symptoms, like redness, swelling, pain or localised discharge.…

Cytokines are extracellular signaling proteins formed by various cells types in the body. Interleukin-6 (IL-6) is a proinflammatory cytokine and lymphokine. IL-6 is produced by almost all different types of lung cells including endothelial cells, airway epithelial cells, fibroblasts, and, most notably, alveolar macrophages. IL-6 is thought to play a role in all types of acute lung inflammation through its stimulatory effects on lymphocytes and the acute phase response. Interleukin-8 (IL-8), a CXC chemokine, is an important neutrophil chemoattractant and activator.…
There are four major categories of tissues in the human body. Each of them separate into even smaller groups with specific structures and functions. The four major types are epithelial tissue, connective tissue, muscle tissue and cardiac tissue. They are all necessities of the human body and contribute to many functions our bodies and cells carry out in order to survive. Tissues interact and group together to make up organs which then compose systems and the human body all together.…

What is the inflammatory response? According to "Definition of Inflammatory Response" (1996-2014), it is “a fundamental type of response by the body to disease and injury, a response characterized by the classical signs of ‘dolor, calor, rubor, and tumor’ -- pain, heat (localized warmth), redness, and swelling.” A very important part of the body’s defense system is inflammation; this is when there is a crucial protective response by the body’s system of self-defense (Definition of Inflammatory Response, 1996-2014). Acute inflammation lasts only a few days, it is short-lived whereas chronic inflammation lasts longer; like weeks, months, and maybe even years. When the inflammatory process is involved in healing and repair it may cause tissue damage. Inflammation can play a role in many disorders; for example Alzheimer’s, asthma, diabetes, osteoporosis, and even HIV/AIDS.…
