Degree: Biological Sciences (Bachelors) - Edinburgh University
My name is Anna and I study Biology at the University of Edinburgh. I would like to use my knowledge and experience to help those who feel they need it and, having had tutors in the past, know how invaluable one to one teaching can be.
I have experience in one-to-one tutoring for GCSE chemistry and this has taught me to adapt to students' resources and to help with off topic queries.
I am the eldest of four and so am accustomed to going through homework and essays with my younger siblings. I have also been a babysitter for several years and this often involves helping children with their homework.
Before we meet for a session, I will find out which topics you want to cover and how you would like to cover them, for example by doing exam questions or going back to basic concepts. This way, I can be prepared and you can get the most out of your session. I am completely flexible to work at any pace and in a style that best suits your methods of learning.
I also have a strong background in Maths and Chemistry and so fully understand the core principles of Biology, making it easier for me to explain to others.
Whether you’re mystified by the molecular wonders of the cell or perplexed by plants and their inner workings, I am here to help so just let me know if you would like to arrange a meet-the-tutor session.

Gas exchange is when oxygen is transferred from the air in the lungs to the blood and carbon dioxide is transferred from the blood to the air in the lungs. It occurs in the alveoli of the lungs.
The lungs have 5 main specialisations to allow efficient gas exchange:
1. A large surface area for more gas exchange to occur over.
2. A moist surface to dissolve gases and increase their rate of diffusion.
3. Thin walls so that gases diffuse over a shorter distance.
4. A large blood supply so that steep concentration gradients for carbon dioxide and oxygen to diffuse down are maintained.
5. Ventilation through breathing to remove carbon dioxde and bring in new oxygen. This helps maintain steep concentration gradients for both gases.see more
