(Dissection Lab) Our heart beats passionately. It never stops. It never rests. It works around the clock, day and night. We will journey into a whole new dimension. First, we will take a historical excursion through the pages of time and see how our knowledge of the circulatory system has expanded. We will learn all about blood, where it comes from, and how clots develop. Next, we will wade through the life-giving fluid that courses through the highways of your body. We will enter the atrium of the heart and peer into the heart’s many rooms. Witness the wonderful cooperation of our heart with our lungs. Peer into the chambers of a real heart and hold this amazing muscle in your hands.
