8.12 ECG investigation

Instructions

Here is the recording link for the class that covered this material. I will update with this year's recording once we go over the material in early November. 
11/17/23 Recording link - the video link we watched during class can be found in the slides below.
2/23/24 Recording link.

Here are the class slides if you would like to review the content in this assignment. 

Please check out the grading information document attached below to be sure you have completed all work needed to earn the score you are aiming for.

1

What is autorhythmicity?

2

What two other body systems help determine the rate of the electrical impulse that makes the heart beat?

4

Match the characteristics of each type of cardiac muscle cell with their cell type. (there are 2 correct characteristics for each cell type)

Found in all 4 chambers of the heart
Are responsible for the squeeze of the heart
Make up the electrical conduction system
Found in specific areas of the heart

Myocardial CONTRACTILE cells
Myocardial CONDUCTING cells

1

In a healthy heart, the electrical impulse travels through the heart using a consistent path that allows for the contraction and resting phases of the chambers to be coordinated.

7

Drag the terms below the diagram to their correct position on the diagram of the heart. 

Which structure is considered the pacemaker of the heart?

3

After the electrical impulse reaches the AV node (the area between the atria and ventricles), put the areas below in order to show the flow of the electrical impulse through the heart.
The AV node should be first

Purkinje fibers
Bundle of His
AV node
Bundle branches

Have you checked the Grades tab in the online classroom to see your current points total?

You can also see the points earned by visiting your Formative homepage as I've shown below. I will be updating scores in the gradebook over the next week but let me know if you've made corrections that I haven't updated yet.

There is just one assignment left for our class, the Medical Terms final part 1! Congratulations, it's been a fast-paced trimester!!
