Unit 3.1 Cardiopulmonary Connection: the transplant-allocation debate, blood flow and vessels, the heart model and EKG, cardiovascular calculations, then the ventilator debate opens the pulmonary side.
Your PLTW coursework: Human Body Systems ▸ Unit 3: Adventure Awaits ▸ Lesson 3.1 Cardiopulmonary Connection ▸ "Activity 3.1.1 Go With the Flow", "Activity 3.1.2 Cardiopulmonary Calculations", "Activity 3.1.3 Stayin' Alive?"
What to do if absent- CER:
- Claim, Evidence, Reasoning: make a claim, back it with evidence, explain your reasoning.
- SOP:
- Standard Operating Procedure, the exact steps to follow (especially in a lab).
- Tracker:
- Your PLTW progress log where you record completed evidence.
- myPLTW:
- The PLTW course site where you do the online activities. Find it in Clever with your Microsoft sign-in, right next to Schoology.
Trace blood flow through the four chambers of the heart and interpret the basic features of an EKG tracing across the .
- 1Label the atria, ventricles, and major vessels on a heart diagram or model.
- 2Define , vein, and and describe what each type of vessel does.
- 3Trace one drop of blood from the body through the heart, lungs, and back out to the body.
- 4Identify the parts of the and connect them to a heartbeat you can feel as a .
- 5Examine a sample EKG and locate the repeating pattern that marks each beat.
- 6Compare a normal EKG to an irregular one and describe one visible difference.
- • 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 EKG tracing.
Open any day for its full lesson, the work due that day, and guided notes.
Written ranking of transplant allocation criteria with a one-sentence justification for the top criterion and acknowledgment of one tradeoff.
Annotated EKG trace with P, QRS, and T waves labeled and linked to phases, plus a recording resting and with units.
Written CER comparing EKG and blood-pressure data to normal reference ranges: specific claim, two measurement evidence entries, mechanism-based reasoning, and one factor that could alter readings.
Written position on ventilator allocation, citing one ethical criterion and naming one genuine tradeoff in decisions.
- Hook: your heart beats about 100,000 times a day, and an EKG lets a clinician read every one of those beats.
- Today's goal: trace blood through the heart and read the basic shape of an EKG.
- 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 this: Advance the PLTW Cardiopulmonary Connection benchmark by completing the online evidence on heart structure and EKG interpretation in the course shell.
- • 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 EKG records the electrical activity of the as a repeating pattern.
- • Trace blood flow through the chambers of the heart.
- • Identify the basic features of a normal EKG tracing.
📋 PLTW evidence due: cardiovascular data check tracing heart blood flow and labeling EKG features, submitted on the class site.

Fiction. There is no such student. The lessons, labs and dates are the real planned course; the student, the classmates and the conversations are invented.
This explainer accompanies the PLTW lab protocol: watch it before lab.
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 myPLTWSign 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.
You can't do those from home: do this instead: Teacher-posted data/model packet, same objective. Supplemental: Khan: circulatory system; EKG basics teacher-selected.
