History Anthrax was known by the names wool sorters and rag-pickers disease in 1800. This was because workers used to contract the disease through bacterial spores present in wool or fabric fibres. Spores are small thick-walled in the dormant stage of some … Continue reading Explainer | What is Anthrax and why is it dangerous?

When the oocyte is matured it is expelled from the ovaries and then travels down the fallopian tube. Eggs pass through the fallopian tube to the uterus where they are fertilised. They burrow into the walls of the … Continue reading Explainer| The Menstrual cycle
