4.1.1 Heart Diagrams
In this activity, we drew both the interior and exterior of the heart. The interior showed the path of oxygenated and unoxygenated blood through the heart. The exterior showed the parts of the heart in more detail.

Unoxygenated Blood Flow through the Heart
Unoxygenated blood enters the heart from the body through the Super Vena Cava and the Interior Vena Cava. It then travels into the right atrium. From the right atrium, it flows down into the right ventricle through the tricuspid valve. It then flows out of the pulmonary arteries to be oxygenated by the lungs. |
Oxygenated Blood Flow through the Heart
Oxygenated blood enters the heart from the lungs through the pulmonary veins. It then travels to the left atrium. From the left atrium, it flows down into the right ventricle through the mitral valve. It then flows out the aorta to be delivered to the body. |
4.1.2 Anatomy of the Heart
In this activity, we labeled and dissected a preserved sheep heart.

4.2.1 Heart Rate
In 4.2.1, we used Logger Pro software to record and collect data from our heart rate experiment. We tested how breathing patterns (normal, in 3/out 3, in 6/out 6) affects your heart rate. In conclusion, the longer the breaths, the slower the heart rate.

4.2.2 Blood Pressure
In this experiment, we tested blood pressure using the Logger Pro software. We tested how talking while having your blood pressure measured affects the reading. In conclusion, talking does increase your blood pressure.

4.2.3 EKG
In this experiment, we learned to how to test and read EKGs They are read at different intervals (seen below). After collecting our readings, we compared them to the "normal" readings.

4.3.1 Cholesterol Guides
To better understand cholesterol, refer to the table on LDL//HDL to determine the difference between good and bad cholesterol.
In this activity, we made cholesterol guides to infer the general population on why cholesterol health is important.

4.3.2 Hypercholesterolemia
In this activity, we caught back up with the mystery of Anna Garcia's death. We ran samples from her and her family's DNA to test for hypercholesterolmia, "high cholesterol disease". The samples were loaded into a gel and then tested through gel electrophoresis. After an electrical charge had been sent through and the gels had been unstained, we were able to see and compare the DNA.
*Each well was labeled with a unique DNA sequence, shown below.
After the DNA was analyzed, we were able to make a pedigree showing the family history of hypercholesterolmia.

4.3.3 Heart Pump Model
In this experiment, we were challenged to use common materials, such as a balloon, duct tape, tubes, etc. to transfer 150 mL of water from one flask to another, without touching the "pump" aka the balloon. Our plan was to elevate one flask, and have to balloon give enough pressure to move water through the tube into the other flask. It worked!
A pump may actually be put in a heart if it is not able to "transfer" blood from the atrium to the ventricle.

4.4.1 Major Heart Procedures
Angioplasty
An angioplasty is a procedure that is done through the groin to the heart. A thin, narrow balloon is taken on a wire through the blocked vessel. It is then blown up to widen the blocked vessel, and then removed.
Stenting
A stent is a procedure that is done through the groin to the heart. A spiral wire is put on a thin, wire to insert into the blocked vessel, it is left in the vessel permanently.
Coronary Bypass
A coronary bypass is done when the problem is more serious. A healthy blood vessel is taken from another part of the body and inserted into the heart. The vessel is attached to the aorta and into the blocked coronary artery. It provides a sort of bypass, so that the blood can flow freely.

4.4.2 Patient Plan
In 4.4.2, we were assigned a patient that suffers from an undiagnosed heart problem, along with other medical problems. We were then asked to work in groups as medical professions to diagnose our patient.

Manuscript
Using my heart rate experiment, I wrote a manuscript, scientific paper, to discuss the methods and results of the experiment. Check it out!

Owensboro Heart and Vascular
During this unit, we took a field trip to Owensboro Heart and Vascular. We got to meet the medical professionals and learn about all the super cool diagnostic tools they use to diagnose heart problems.
