同学们首先研究了心脏的外部结构, 识别心脏的前部和后部以及主要血管。他们还可以看到冠状血管，如果这些血管阻塞了会导致心脏病发作！

The external structure of the heart was first studied. Students could identify the anterior and posterior part of the heart and the major blood vessels. They could also see the coronary blood vessels, the ones which, if blocked, led to a heart attack!

最让同学们兴奋的是解剖心脏的部分, 他们着迷于看到内部结构的样子，肌肉的力量和厚度，以及心脏左右部分的明显差异。他们可以识别左右心室和心房、主要血管、保持含氧和脱氧血液分离的厚隔膜。内部最奇特的结构是“心弦”，即支撑心脏瓣膜的腱索。

The exciting part was cutting the heart open. The students were fascinated at seeing what the internal structure looked like, how powerful and thick the muscles were, and the clear difference between the right and left parts of the heart. They could identify the right and left ventricles and atria, the major blood vessels, the thick septum that kept the oxygenated and deoxygenated blood separate. The most peculiar structures inside were ‘the strings of the heart’, the chordae tendinea which held the valves of the heart.

在探索和研究了心脏的所有不同区域后，同学们绘制了心脏的内部结构图。随堂的工作表，让同学们进一步了解了解剖课堂的概念，并测试他们所学到的知识。

After exploring and studying all the different areas of the heart, the students made a drawing of the internal structure. They were also given worksheets which further explained the concepts to them and tested their knowledge.

同学们都非常投入这堂实践课，并对活体、人体系统和器官的运作有了很好的了解。

The students enjoyed the class and had a good visualization of how the living body, systems and organs work.
