The Circulatory System, Part 2

The Circulatory System, Part 2

In the second of our two-part series for the circulatory system, we discuss the chemical and physical science applications of the circulatory system. The latter has big overlaps with fluid dynamics, gas exchange, and even Ohm’s law. Join us to see how the MCAT tests the circulatory system from biological angles and beyond.

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!

Testimonial

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.”
