Role of the parts: Lymph nodes – Lymph nodes are enclosed, located around the lymph vessels. Lymph nodes are a key organ of the immune system and they make white blood cells which help fight off diseases. They also create antibodies to neutralize infections. They do this by producing lymphocytes protects the body from harmful microorganisms, unknown particles and removes litter from the lymph. Innerbody [online]
Another organ is lymph node that is has specialized compartments where the immune system there and can encounter antigens. It shaped is small and bean shapes that are there in neck, armpits, abdomen and groin. As mentioned above, that there is lymphatic vessels, so that the immune cells and all the foreign particles will enter then exit through outgoing lymphatic vessels. When they in bloodstream, then they will transported to tissues to all the body. Then, they will back to the lymphatic system and repeat the
Identification would be identifying and treats promptly in order to shorten the time during which they can infect others. Isolation would be isolating the infected persons prevents contact with susceptible persons and stops the spread of the disease. 5) Explain: a) What is the difference between HIV and AIDS? HIV is early stage of the infection. HIV is an RNA virus that belongs to a class of viruses called retroviruses.
Results and Discussion The group viewed each specimen in the microscope, the members then observed four types of tissues. Each tissue was identified. The results are as follows: • Epithelial Tissue - The epithelial tissue covers majority of the body surface and also makes up the lining of some internal organs. This tissue is responsible for the protection of the body from dust, dirt, bacteria and other organisms that lie outside the body, it may also be changed/modified to glands that produce mucus, hormones, enzymes and etc. , also all epithelial cells are supported by a basement membrane underneath it.
Strep Throat is an infectious bacterial disease that is contagious and is caused by the inflammation and swelling in the lining of the mucus membranes in the back of the throat and the tonsils. The throat gets a burning sensation and a severe irritation, causing a sudden, severe sore throat. Strep throat generally affects the throat and tonsils and makes swallowing hard. Sometimes a sore throat is mistaken for strep throat. Sore throats are mostly caused by a viral infection and not the streptococcal bacteria.
This kind of Staphylococcus aureus is called “MRSA”, referred to methicillin-resistant S. aureus. This bacteria are multi-resistant to beta-lactam antibiotics, meaning that they are resistant to different kinds of antibiotics, such as penicillin, methicillin, dicloxacillin and cephalosporin. As the process goes, that normal Staphylococcus aureus are being killed by penicillin antibiotic, and the ones that are resistant survived and keep on reproducing, Staphylococcus aureus bacteria that is penicillin resistant spread in the community and its amount kept on increasing. This made natural selection to occur, which the bacteria that are antibiotic resistance are suitable ones and they survived in
When an antigen invades the body, normally only those lymphocytes with receptors that fit the contours of that particular antigen take part in the immune response. When they do, so-called daughter cells are generated that have receptors identical to those found on the original lymphocytes. The result is a family of lymphocytes, called a lymphocyte clone. with identical antigen-specific
Host defence comprising many biological structures and processes within an organism that protect against various diseases is known as immune system(97). Immune system can be classified broadly in two sub-systems, the innate immune system versus the adaptive immune system, or humoral immunity versus cell mediated immunity. In humans, the blood-brain barrier, blood-cerebrospinal fluid barrier separate peripheral immune system from the neuroimmune system which protects the brain(98). Malfunctioning of immune system can result in autoimmune diseases, inflammatory diseases and cancer. Less active immune system results in life threatening infections and various immunodeficiencies.
Magnetic-resonance imaging (MRI) is used to confirm or rule out brain or brain stem involvement.  Clinical symptoms; Symptoms include diarrhea, fever (high temperature), nausea, vomiting and flu-like symptoms. listeriosis is a serious disease in humans; the overt for of the disease has a case fatality rate around 20%. The two main clinical manifestations of the disease are sepsis and meningitis. In the case of meningitis, it is commonly complicated by encephalitis, when it is known as meningoencephalitis, a pathology that is unusual for bacterial infections.
Not only do white blood cells help your body fight off disease, illness, and infection, but they contain granules, which consists of enzymes, that can help fight your body against unknown items like viruses of bacteria particles (Ballard, 33). While some white blood cells surround this unknown item, killing it, some white blood cells develop a "memory" of that unknown item, so they can have a swift attack on them (Ballard, 33). In addition to plasma, red blood cells, and white blood cells, there are platelets. Platelets are disc-shaped cell fragments that prevent a great amount of blood loss from cuts by developing platelet "plugs," as their granules contain chemicals that make blood clot (Ballard, 33). What is blood pressure?
