Do you know all the parts of the heart?

Use the link under the human body to see how blood flows through the heart (When does blood have more oxygen present?)

Why are the walls of the left ventricle thicker than the walls of the right ventricle?

The left ventricle has thicker walls because it uses this extra muscle to propel blood to and through the aorta to the rest of the body.

Today we heard from the CARDIOLOGISTS…Thank you Rachel and Ashley! We began our external and internal observation of a sheep heart. KNOW YOUR PARTS! Current grades were given out today…do you have any missing assignments to turn in? Tomorrow we will hear from our Pulmonary Respiratory Therapist….Justin.

Homework: Read pages 620 – 623 and complete STARS notes for the respiratory system.  ALL 3 STARS Notes will be due on Thursday, Feb 4th. Pace yourself!
