亞加達國際預(yù)科生物課心臟解刨。

上周生物課的同學(xué)們非常興奮，因為他們有機會解剖一顆真正的心臟!身穿著白大褂，手持解剖剪刀和手術(shù)刀，實驗室看起來就像一個手術(shù)室。有些同學(xué)表示很興奮，有同學(xué)感到害怕，還有一些同學(xué)更喜歡遠(yuǎn)觀。

The biology class students were very excited last week as they had the opportunity of dissecting a real heart! Dressed in white lab coats and with all the scissors and knives around, the lab looked like a real operation theater. Some were thrilled, some afraid, and a few preferred to watch from far.

學(xué)生們首先觀看了一段如何解剖心臟的說明視頻, 緊接著就是學(xué)生們的親身實踐。他們必須握住心臟并將其放在解剖托盤上進行解剖, 雖然有些同學(xué)在尖叫聲，但讓他們激動的是他們手中握著一顆真正的心臟!

Students first watched a video with instructions on how to dissect the heart. They then had to hold the heart and put it on the dissecting trays. There were some screams at that time, but they were thrilled holding a real heart in their hands!

同學(xué)們首先研究了心臟的外部結(jié)構(gòu), 識別心臟的前部和后部以及主要血管。他們還可以看到冠狀血管，如果這些血管阻塞了會導(dǎo)致心臟病發(fā)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!

最讓同學(xué)們興奮的是解剖心臟的部分, 他們著迷于看到內(nèi)部結(jié)構(gòu)的樣子，肌肉的力量和厚度，以及心臟左右部分的明顯差異。他們可以識別左右心室和心房、主要血管、保持含氧和脫氧血液分離的厚隔膜。內(nèi)部最奇特的結(jié)構(gòu)是“心弦”，即支撐心臟瓣膜的腱索。

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.

在探索和研究了心臟的所有不同區(qū)域后，同學(xué)們繪制了心臟的內(nèi)部結(jié)構(gòu)圖。隨堂的工作表，讓同學(xué)們進一步了解了解剖課堂的概念，并測試他們所學(xué)到的知識。

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.

同學(xué)們都非常投入這堂實踐課，并對活體、人體系統(tǒng)和器官的運作有了很好的了解。

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