The heart is a pumping device for blood. Is there a separate blood supply for the heart wall?

Hi Liam, you are correct, the heart does have its own blood supply. It originates at the base of the main artery that leaves the heart, which is called the aorta. Oxygenated blood in the left ventricle passes into the aorta when the heart contracts. Thean when the heart relaxes the valves into aorta close. The blood that’s now in the aorta flows through small outlets into the hearts own blood vessels. These are called the coronary areteries. These are arranged to provide oxygenated blood to the heart wall and are drained back into the heart. I hope that helps!

Alisha Khanum

Online lessons

Graduate from UCL. Really enjoy tutoring and helping others

Hi :) I'm Alisha. Ive been told that I am an individual who has a positive can do attitude and easy going. You can let me know if this is true ? I've been tutoring for almost 9 years now and absolutely enjoy it. Especially knowing that I'm helping students to build a strong foundation to set them up for the future. I have tutored students from KS1 upto A-levels, teaching Maths and Sciences (and English to younger students). Not only have I tutored students, I have had the amazing opportunity (and a challenging yet unique experience) to also home school a number of students in the past. Misc: I am a socially active person who enjoys trying out new activities or visiting new places. Next on the to do list is sky diving (ahhhh). I also try to be actively involved in raising funds for different charities. For example, I have helped organise charity events to raise funds for educational resources and schools in rural developing countries and orphans in need.

Abdur Khan

Second year dental student, happy to help :)

Hi, my name is Abdur and I’m currently studying Dentistry at the University of Bristol. I’d describe myself as a kind and friendly person who loves to teach using evidence-based techniques. As a dental student, a lot of my time is spent learning but also teaching others as it reinforces the knowledge I’ve gained from lectures, seminars and clinical sessions. I’d describing my style of teaching as interactive and personal as everyone has their own way of grasping topics. What sets my teaching apart from others is that it integrates core topics and links the common themes which cements the information to a deeper level of understanding. This is something I’ve used in my own studies which has helped me to ranked in the top 10 for the end of Year 1 exams and over achieve over 70% in end of Year 2 exams. I have been tutoring and mentoring students since 2016. What I’ve learnt from this experience is that building confidence in students is one of the key components to boosting grades. I highlight strengths and weaknesses so we can reinforce the areas which require more attention. This is through evidence-based teaching called active recall. The purpose of this method is to stimulate the mind through questioning rather than passive learning. Passive learning is something many students are guilty of which often leads to average grades. Through active learning it highlights areas that requires more attention. Spaced repetition will help to prevent forgetting important information and enables long term storage of knowledge which is crucial for exams!
