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. 

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.

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

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.

This is the final graded assignment for our class! Congratulations, it's been a fast-paced trimester!!

What is autorhythmicity?

The ability of cardiac muscle to communicate with the brain

The ability to generate an electrical impulse at a regular rate from cell to cell to trigger a contraction

The way the heart and lungs work together automatically. 

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

nervous system

skeletal system

endocrine system

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

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.

True

False

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?

AV node

Internodal bundle

SA node

What is atrial fibrillation?

An irregular, often rapid heart rate that causes poor blood flow.

A slow heart beat with excessive blood flow

A normal heart rhythm
