The Circulatory System, Part 1

The Circulatory System, Part 1

In the first of our two-part series for the circulatory system, we discuss the biological aspect of the circulatory system. This webinar covers the think sequence of blood flow, anatomy of the heart, and how fetal and maternal circulations are different. We also review all the key physiological concepts you will need to know for the test.

On the MCAT

  • The circulatory system is the most content and skill rich system on the MCAT. It has a huge biological footprint, but also connects to many areas of basic sciences

  • It is impossible to cover all topics that you might see on the MCAT related to this system, but most of the low yield/other information the passage will provide


I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry.  I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
