A medical common sense, the human body is divided into basic unit parts features refers to what is the composition of the human body is what what what what is called epithelial tissue, connective tissue in the muscle tissue called the neural tissue organ what what? Human organs can be divided into what is the movement system system of human bones are much bone structure is how what is the joint?

Pathogenic microorganisms are how to spread and infection of pathogenic microorganisms to infection of human, we must strain every nerve Defense Agency breakthrough human, growth, in certain parts of the body and cause reproductive, can make the incidence of pathological and physiological. So, how to spread and infection of pathogenic microorganisms are human? Pathogenic microbe is mainly through direct contact with patients, or through the air, water, food, utensils, animal excreta, media communication. Pathogenic bacteria is by virtue of its toxic capsule, produce enzymes of various invasive, produces exotoxin bacteria virulence to form the body to attack. Many pathogenic bacteria in the protection of its capsule, can resist phagocytosis of cell in the body of their phagocytosis and digestion. They invaded the human body, and attacks the body related enzymes in different parts of the body, these enzymes can damage the body's tissues and cells, causing cell necrosis and lysis of red blood cells. There are some pathogenic bacteria can produce exotoxin can kill people, when they grow in the human body, internal and external toxin which can kill cells in the human body. The occurrence and development of pathogenic bacteria infection process, apart from the bacterial virulence and resistance of human body, and environmental factors have close relationship. Seasonal temperatures, dry or wet degree will have different effects on the spread and infection of pathogenic bacteria. With the original bacteria, causing human disease viruses also have very strong toxicity. They enter the body through the host cell, directly killing and destruction of the host cell, forcing the human cells, causing cell damage, thereby affecting the normal physiological function of the body, the lesions appeared. In addition, the virus and the host interaction can also form some lesions. In general, most viruses invade the body, only in certain parts of the body or nearby lymph tissue proliferation generate lesions, the formation of local infection, but if the body cannot eliminate infection, development will become a systemic infection, seriously endanger people's health. What about the virus and tumor tumor is a serious hazard to human health and life and common disease. There are many factors that lead to cancer, in addition to chemical factors, environmental factors, genetic factors, immune factors, hormone balance disorders and mental factors, the virus is also an important factor. Modern oncology research proof, can have two types of the virus to cause tumors: DNA virus (including polyoma virus, adenovirus and herpes simplex virus) and RNA virus (mainly retroviral). Scientists are using biochemical and molecular biological methods, immunological methods and biophysical methods for the long-term mechanism of cancer on the virus, DNA virus is to integrate their genomes into normal cell genome, using readily available methods and tools in the cell, make the combination of virus and cells, the cells become malignant. And a reverse transcriptase present in the RNA virus, the RNA virus reverse transcriptase that can synthesize complementary DNA, the DNA carcinogenesis are integrated into the cell genome cause of human tissues and organs. At the same time, the cause of single factor also denied the virus as a human cancer. For example, so far, has not yet found a tumor is infectious. In recent years, with the epidemiology of cancer pathogenesis, believe that the formation of the tumor has a causal relationship with certain viruses: nasopharyngeal carcinoma and lymphoma Burkitt -EB virus, worldwide, a year about 50000 people suffering from nasopharyngeal carcinoma; cervical cancer - Ⅱ herpes virus; hepatocellular carcinoma and hepatitis B virus, about 250000 cases of liver cancer and hepatitis B virus each year; leukemia type -C RNA virus. Therefore, usually pay attention to the prevention of the virus, to prevent certain types of cancer, of great benefit. What is the interferon interferon is the body susceptible to a protein produced by the action of cell virus, but no virus specific. Interferon is almost no toxicity and antigenicity, variation in environmental conditions are stable. More importantly, the antiviral protein produced by interferon stimulated cells have inhibitory effect on a variety of virus, a kind of interferon type cells can resist attacks from viruses, is a broad spectrum antiviral substance. The virus with the host cell specific, such as the height, human cells can inhibit interferon almost all virus in human cellsReplication of virus infection, but the interferon bovine and sheep like animal and no interference action. Induction of interferon produced a lot of material, the most important is the virus itself, phytohemagglutinin, endotoxin, protozoa and bacteria. In the early stage of virus infection, it can limit the spread of the virus, the virus infection to interrupt. In the event of viremia within a few hours, the emergence of new interferon can in serum, and can reach the site where the virus quickly, play a strong inhibition of the virus, it has great significance in the control of virus infection can spread throughout the body. Because interferon is the metabolic products of the cells, to large-scale mass production is still very difficult. Scientists came up with some imitation virus material is injected into the human body, can directly induce the cells to produce interferon. At present, artificial interferon inducing agent has been applied to clinical, has a good effect on herpes simplex keratitis, viral infection of the respiratory tract. Leukocyte interferon and human fibroblast interferon on certain viral infections such as the curative effect of chronic hepatitis, herpes zoster is also very significant. What is the parasite? How parasites infection of human in our life in the nature of various animal (including humans) often have a variety of insects on or in the body of life, they need nutrients from the parasitic animal body, these insects are collectively referred to as the parasite. Human parasitic protozoa, can be roughly divided into 3 categories, worms and insects. Protozoa: unicellular animal parasites, than bacteria, but also to use optical microscope can see. Protozoan parasites mostly have a nucleus, and the pseudopodia, flagella or cilia movement of nuclear free, the formation of inactive and strong resistance to adverse environment cysts, become the important link for disease transmission. The human body has 30 kinds of parasitic protozoa, including dysentery Amiba, Plasmodium, Leishmania donovani, Trichomonas vaginalis and so on. They are parasitic in the blood, organs, intestinal tract, oral and intravaginal, spread by direct contact or contact with contaminated cysts, insect vector. Main protozoal diseases include malaria, Kala Azar, amebic dysentery and trichomonas vaginitis.......
