makes maintaining hemostasis inside and out of the gastrointestinal tract vitally important. The epithelium of the gastrointestinal tract is of great importance because it provides a physical barrier‚ it decontaminates or eliminates detrimental intestinal substances‚ and it ensures the mucosal immune response. If there is any disturbance of the flora then‚ there is an amplified danger of resulting metabolic disorders‚ inflammatory‚ and allergic diseases (Breton‚

. Understanding the causes of infection 1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacterial and fungi infections are easy to cure with the use of antibiotics‚ where as viruses can be hard to cure or vaccinate against‚ such as the common cold. Bacteria can be found everywhere and anywhere Soil‚ Water‚ Plants‚ Animals‚ material and even deep in the earth’s crust. Bacteria feed themselves by making there food with the use of sunlight and water. We would not

Ecosystem Components and Interactions I. Introduction An ecosystem is a complex relationship between a community of organisms and the environment that they dwell in where energy is exchanged and transformed. Ecosystem includes the biotic (living organisms)‚ the abiotic (physical and chemical factors)‚ and the interactions made between these. They continually interact with each other‚ thus making complex systems with intersecting properties wherein “everything is connected”. In ecosystem ecology

Toxoplasmosis is a disease caused by a parasite called Toxoplasma gondii (T. gondii). It is an intracellular parasite in the phylum Apicomplexa‚ and its life cycle completed only in cats and other felids (the definitive host). However‚ T. gondii also infects a wide variety of intermediate hosts‚ including humans (Wastling et al.‚ 2000). Humans get infection either by the ingestion of tissue cysts in infected meat or by the ingestion of water or food contaminated with sporulated oocysts derived from

Pollination is service provided by insects and other small animals. Also Honey-bees distribute pollen among plants of the same species. This function of ecosystem could not be imitated by any jet invented technology. Plants

Sponges range in height from about 1cm to 2cm. 4. More than 5000 species of sponges are found. 5. All are marine‚ while some are fresh water. 6. The central body cavity is called spongocoel. 7. A single large opening is called as osculum. 8. They are filter feeders. 9. Body lining is formed by flagellated cells

Bacteria is something that we need some of‚ it needs a warmth‚ moisture‚ time and food in order to multiply‚ which in the right conditions they multiply quickly. Viruses need a living host in order to survive‚ they don’t respond to antibiotics and new strains of virus are developing all the time. Fungi are moulds and yeasts‚ they need a warm and damp environment to survive‚ much like bacteria. Parasites feed off the host it’s inhabiting‚ it uses

On examination‚ the patient was mildly shocked and his abdomen was tender in the epigastric region with slight guarding. There was no evidence of either intestinal obstruction or perforation of a viscus on radiographic examination. Blood was taken for urgent biochemical investigation.
