Degree: Biomedical Science (Bachelors) - Durham University
My name is Anna Chaplin and I am a first year student at Durham University. I am studying Biomedical Science and I hope to do a PhD in Immunology after my degree. I successfully completed the International Baccalaureate with 39 points, and carried out my Extended Essay in Biology.
Having completed HL Biology, I know how difficult it is to remember and understand the vast amount of content that there is to learn. However, I hope to show that many topics interlink and that understanding aspects of one topic can really benefit understanding in another. I can also provide past paper questions and help improve exam technique so that you get the grade you deserve.
I am currently a tutor in Biology in a group run by my University and I often help my sister with A-level Biology and Chemistry related problems so I have had previous tutoring experience.
I believe I am an approachable individual who communicates ideas clearly and concisely. I hope to share my enthusiasm of the subject as well as encourage students not to be afraid to get things wrong and ask questions.

The function of a blood clot is to prevent blood loss from damaged blood vessels. In order for a blood clot to form, activated platelets and the damaged tissue release clotting factors which are proteins in the blood that control bleeding. The clotting factors then catalyse the reaction of the inactive zymogen, prothrombin to the active form, known as thrombin. Thrombin catalyses the conversion of soluble fibrinogen into insoluble fibrin which forms a mesh of fibres over the damaged area to help trap blood cells. The platelets can then stick to the area of damage and form a solid clot. This mechanism is vital as it prevents serious blood loss and stops pathogens from entering the body via the injury.see more
