The substance of the lymph hub is separated into the external cortex and the internal medulla The capacity of lymph hubs is the creation of lymphocytes‚ which shield the body against microorganisms and against dangerous outside particles and flotsam and jetsam from lymph before it is come back to the circulatory system. Lymph vessels Lymph vessels are dainty walled‚ valved structures that convey

responded and over some time has slipped back and stopped working so the patient has the same symptoms as they did before. There are two types of refractory sprue. Type one is a normal population of intraepithelial lymphocytes. Type two is an premalignant population of intraepithelial lymphocytes based upon clonality analysis of t-cell receptors and immunophenotyping. Type one can never lead to type two‚ a patient either has one or the other. Type one also has a higher survival rate of a five year study

The lymph nodes are oval‚ bean shaped organs which contain concentrated areas of lymphocytes‚ a type of white blood cell‚ and macrophages. The lymphocytes produce chemicals called antibodies‚ special proteins that fight off germs and prevent infections from spreading‚ which kill micro-organisms in various ways‚ either by surrounding the

hematocrit or anemia means that the percentage of red blood cells is below the lower limits of normal. It could be as a result of internal bleeding‚ nutritional problem or over hydration. When there is a bacterial infection‚ the hematocrit is raised. Lymphocytes are types of white blood cells. They are the body’s primary immune defense and move through the lymph in response to antigens and pathogens. T-cells originate in the bone marrow and migrate to the thymus to mature; B-cells also originate in the

Abstract Every body contains blood. It is the life force that allows the body to function properly. It is a specialized fluid that is pumped by the heart and circulated through the body via a system of arteries and veins. It is an essential component of the body and without it we would not be able to survive. This paper discusses the anatomy and physiology of blood in a brief review. Anatomy and Physiology of Blood The blood is made up of four main components. These are plasma‚ red

The movement of water down its osmotic gradient across a selectively permeable membrane is known as osmosis. The difference in the concentrations of solutes on either side of the membrane results in the establishment of an osmotic pressure. Water follows the direction of solutes‚ this means that in the event where there are more solutes outside the cell than there are inside the cell‚ water will move from the inside of the cell to the outside in order to establish water balance. When a cell is placed

University Abstract: Steven Johnson Syndrome is an inmune disease charactherized by a detachment of the epidermis from dermis. It could be fatal and the pathophysilogy involves a complex hypersensitivity reaction with the participation of T lymphocytes that induce keratinocyte’s apoptosis. The syndrome can be cause by drigs‚ infections and malignancies. The diagnosis is difficlut due to the abscense of specific manifestations and laboratory tests. There is a genetic predisposition in individuals
