Dissection: Heart

We dissect and examine a cow\u2019s heart to show the position and function of different parts. This includes the coronary artery, ventricles, atria, pericardium and the thickness of the muscle tissue.

Biology - Human Body - Learning Points.
The heart has two sides, each with two chambers: the atrium and ventricle.
Valves in the heart ensure that blood flows in one direction.
The cardiac cycle is the sequence of events that occurs when the heart beats.
Blood flows into upper chambers called atria, which contract and force blood into the ventricles (diastole phase), and the ventricles contract to force blood out of the heart into the arteries (systole phase).
A healthy lifestyle is essential for a healthy heart.
