Week overview - Cardiopulmonary Connection: heart structure and reading an EKG

Apr 19–23

Trace blood flow through the four chambers of the heart and interpret the basic features of an tracing across the .

Week arc
  1. 1Label the atria, ventricles, and major vessels on a heart diagram or model.
  2. 2Define , vein, and and describe what each type of vessel does.
  3. 3Trace one drop of blood from the body through the heart, lungs, and back out to the body.
  4. 4Identify the parts of the and connect them to a heartbeat you can feel as a .
  5. 5Examine a sample and locate the repeating pattern that marks each beat.
  6. 6Compare a normal to an irregular one and describe one visible difference.
By week end
  • • You will be able to trace blood flow through the four heart chambers.
  • • You will be able to distinguish arteries, veins, and capillaries by function.
  • • You will be able to identify the repeating pattern in an tracing.

Get oriented

Quick intro to the week

  • Hook: your heart beats about 100,000 times a day, and an lets a clinician read every one of those beats.
  • Today's goal: trace blood through the heart and read the basic shape of an .
  • This week's Monday bioethics debate: who should get priority for a heart transplant when organs are scarce?
  • Reminder: your graded cardiovascular data check lives in the PLTW course shell, not on loose paper.
Do the work

Your PLTW coursework this week

Do this: Advance the PLTW Cardiopulmonary Connection benchmark by completing the online evidence on heart structure and interpretation in the course shell.

Know when done
  • • Blood flows through the heart in a fixed path between atria, ventricles, lungs, and body.
  • • Arteries, veins, and capillaries each play a distinct role in circulation.
  • • An records the electrical activity of the as a repeating pattern.
Be able to do
  • • Trace blood flow through the chambers of the heart.
  • • Identify the basic features of a normal tracing.

📋 PLTW evidence due: cardiovascular data check tracing heart blood flow and labeling features, submitted on the class site.

All PLTW activities are completed inside the PLTW course environment: this page only gives direction.

What to do when absent

If YOU are absent

Most days, this class is your PLTW coursework: and PLTW is online and individual. So being out usually just means doing exactly what we did in class, from home.

Open Clever, then myPLTW

Sign in to Clever with your district Microsoft account to open Schoology or myPLTW. Follow today's posted steps. If myPLTW will not open, use the posted alternative and tell Mr. Mendoza. Turn in your completed work through the Schoology assignment.

Was today a lab or a group activity?

You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: circulatory system; basics teacher-selected.

If MR. MENDOZA is absent

Class still runs. A substitute will post today's plan: complete the online activity above; it's built to be self-guided. Need the concept taught without a teacher? Use this authoritative explainer:
