Hello, my name is Iro and I am currently on my first year of studying Βiology at Imperial College London. Having graduated from secondary school relatively recently, I find it easy to identify with the students and provide them with advice about their revision as well as their plans for the future. During the last two years of school, I studied for the International Baccalaureate, which is very similar to the A-Levels, and I achieved an overall grade of 43/45, with 7/7 In High Level Biology and Chemistry. You can see my detailed results at the section below.
I have tutoring experience with both younger and older students. During the past year, I tutored a group of A-Level Biology students. I am therefore quite familiar with the parts of the syllabus they find the most challenging and the common questions that might arise. I am prepared to help them in terms of some revision tips for their exam preparation as well. I have also worked as a mentor for a sixth grade student, helping her with her homework and her plans for the future. Interacting with younger students is a challenge, as all the concepts have to be explained in a very concise and efficient manner. Thus, mentoring a sixth grade student has been a valuable experience for me.
If you feel that I could help you in any way, regarding both a specific subject and any concerns about the future, do not hesitate to contact me!

1. Arteries have a much thicker wall to withstand the high pressure of blood flowing in them, whereas veins have a thinner wall so that they can be pressed flat against adjacent muscles, helping to move the blood.
2. Veins have valves, contrary to arteries, to prevent back-flow of blood flowing in them.
3. Arteries have a narrow lumen to maintain the high blood pressures, while veins have a wide lumen to accommodate the slow-flowing blood.
4. Arteries have a thick outer layer of longitudinal collagen and elastic fibres to avoid leaks, while veins have a thin outer layer of longitudinal collagen and elastic fibres, because there is little danger of bursting.
5. Arteries have a thick inner layer of circular elastic and muscle fibres, to help pump the blood on after every heartbeat, whereas veins have thin layers with relatively few circular elastic and muscle fibres, as blood does not flow in pulses so the wall of the veins cannot help to pump it.
1. Arteries carry blood away from the heart and towards the different areas of the body, while veins carry blood from the rest of the body towards the heart.
2. Arteries, with the exception of the pulmonary artery and the umbilical artery, carry oxygenated blood towards the different parts of the body, whereas veins, with the exception of the pulmonary veins and the umbilical vein, carry deoxygenated blood back to the heart.see more
