The practice of dissection of a lamb heart consists of two parts. The first deals with the study of externally heart and the second deals with the study of the heart inside.
The first thing we had to do was put the heart on a platter and once there, put a color straws for veins and other color straws for artheries.
And in the first part, the first thing we did was examine the appearance of the pericardium with the tweezers, which is a transparent, hard and resistant layer. All continued, we note that the same heart has a conical shape with a size equivalent to a fist. And finally we explore the veins and arteries that are externally.
And the second part takes place the dissection with the help of the scissors. First we had to make a cut in the left ventricle for inspection. And secondly we did the same in the right ventricle.
And finally we had to take a conclusion. In our case, we explained that the dissected heart is not symmetrical as the left ventricle is larger than the right to carry blood through the heart and comply its function.
