| My EKG Chart |
An electrocardiogram (EKG) is a test that checks for problems with your electrical activity of your heart. The EKG translates the electrical activity to paper with a bunch of lines. Those lines are sometimes called waves. Each spike has a wave name! The names that they have are: P wave, P-R Interval, PQRS Complex, and the T wave. The P wave represents the atrial contraction. QRS is the Ventricular contraction, and T is the Ventricular Repolarization.

| COW HEART |
The cow heart was not the biggest that was dissected, but it was pretty HUGE. The right atrium was 3 1/2 cm, right ventricle was 3 1/2cm, thickness of the outer wall was 4cm, and of course you have the tricuspid valve. The aorta was 2 1/2 cm, pulmonary trunk was 2 cm, left atrium was 4 cm, left ventricle was 2 cm, the outer wall thickness was 2 1/2 on the left side, then you have the mitral valve! In all hearts that were dissected, one side of the heart was always bigger then the other. The sheep heart had way smaller measurements then the pig and cow heart. The pig heart however had bigger measurements then the cow heart! all the measurements were measured in diameter!
