  1. Complete Lab 1 on the Heart in the provided PDF. Labs1_Heart Lab Online.pdf (LOCATED IN ATTACHMENTS)
    • Complete the PDF in Adobe Acrobat and save it (DO NOT COMPLETE IT IN YOUR BROWSER, like Chrome, Internet Explorer, Firefox, or Navigator – they WILL NOT save the answers!).
    • You can also print and complete the lab by hand, if you’d like, and upload a scan of the images of the completed pages – see instructions below.
  2. If you choose to do the work by hand, take pictures of the completed pages and create a multi-paged PDF document of the images to submit
    1. The pages must be in order 
    2. I have to be able to see the entire page including the page number
    3. the pages must be clear
    4. The pages must be oriented right side up.

Please create a PDF or Word document with the images in order if you scan in the completed pages. Do not submit images that are blurry, upside down or sideways. I must be able to read the entire page. 

If you have an iPhone, or an iPad,

  1. Go to the “Notes” app
  2. Click on the camera icon or + icon at the bottom of the screen
  3. select “Scan Documents”
  4. take the picture and adjust the corners if needed
  5. If the image looks good select “keep scan” (If it does not look good select “retake”)
  6. You can take as many pictures as needed to create one, multi-page PDF!
  7. Once you are done with all the pages of the document Save.
  8. you will be able to upload this PDF document into canvas and it will be clear with the pages in the correct orientation.

If you have an android or google phone:

  1. Open the Google Drive app
  2. Click on the + (add) icon at the bottom right
  3. Click “Scan”
  4. Take a photo of the document, adjust scan area if needed and tap crop.
  5. to scan another page click on the + (add) again.
  6. You can take as many pictures as needed to create one multi-page PDF!
  7. Save the finished document by tapping done. 

Another thing that has worked well for me is a free app called “Genius Scan.”  Install Genius Scan on your phone, then:

  1. Open the Genius Scan App.
  2. Click on the + (add) icon at the bottom left.
  3. Hold your phone over the page.  The Genius Scan app will automatically identify the page and take the picture.  Or, you can tap the round button at the bottom to take the picture.
  4. Once the picture is taken, immediately move to the next page and take the next picture, then the next.
  5. Once you’ve taken a picture of all the pages in order, then tap “Done.”
  6. A PDF will be automatically created, and you can email it to your self or save it to your phone for submission.

Laboratory UNIT 1 – Circulatory System

Part 2: THE HEART

The circulatory system consists of the heart, blood vessels, blood, and lymphatic vessels.
This series of three labs will assist in your understanding of the anatomy and physiology of each part.

The circulatory system has major roles in the body:

Transport Wastes: Transporting waste products from the tissues of the body to the kidneys.

Transport
Respiratory Gases:

Carrying oxygen from the respiratory surfaces to tissues and carbon dioxide
from the tissues to the respiratory organs.

Transport
Nutrients: Conveying nutrients from the alimentary canal to the tissues.

Protection:
The blood contains cellular components and chemical components that protect
the body via the immune response, the inflammatory response, and the
clotting process.

The heart is a pump with four chambers and valves that maintain a one-way flow of blood. The wall
of the heart includes: (1) cardiac musculature for contraction to propel the blood out of each chamber
and into the major vessels, (2) a fibrous skeleton for attachment of the valves and (3) an internal
conducting system for synchronization of muscle contraction.

Functionally, the heart may be considered to consist of two separate pumps, made up of the right and
left halves. The left half receives oxygenated blood from the lungs and pumps it out to the body
tissues. The deoxygenated blood returning from the tissues of the body passes through the right half
of the heart, which pumps it out to the lungs. Each half of the heart consists of an atrium which
receives the blood and a thick-walled, muscular ventricle that pumps it out, hence a four chambered
heart.

A. Objectives
1. Examine and draw the microscopic anatomy of cardiac muscle tissue.

2. Identify specific structures of the gross anatomy of the heart on images.
3. Trace blood flow through the structures of the heart.

B. Histology of Cardiac Muscle
1. Examine and draw sections of heart muscle. Label the following on your drawings:

• Branched cardiocytes
• Striations

• Intercalated discs
• Nucleus

C. Gross Anatomy of the Heart

1. Read and work through the exercises on pp. 217-223 in the Visual Guide to
become familiar with the anatomy of the heart.

2

C. Using the images of the heart in Canvas, be able to identify the following structures and identify
functions if applicable

Base & apex of the heart
Anterior interventricular sulci & Posterior interventricular sulci
Atrioventricular sulcus (coronary sulcus)
Pericardium
§ visceral pericardium (epicardium)
§ parietal pericardium

Coronary Circulation

Great Vessels
§ superior vena cava
§ inferior vena cava
§ ascending aorta
§ aortic arch
§ descending aorta
§ pulmonary trunk
§ pulmonary arteries
§ pulmonary veins

you begin to flow. List all the structures of the heart through which you will flow – in order – on your
way back to the right atrium. Type the names of the structures into the textbox below.
