Build me a human heart in interactive 3D, in one HTML file with Three.js.
Make it look real: the deep red muscle with the red arteries and blue veins on top, and inside it the parts you never get to see. The four chambers, the four valves, the aorta and the pulmonary artery, the veins bringing blood back, and the wiring that sets the beat. The heart beats about once a second, the valves open and close in time, and the blood flows through it, blue going in and red going out. I can drag to orbit around it and scroll to zoom.
Add an Explode button. When I press it, every part slides apart with its name on a label. Press it again and it all snaps back together. When I hover a part, it lights up and shows one line on what it does.
No images. Do not ask me any questions. Just build it.

用 Three.js 在一个 HTML 文件里为我构建一颗可交互的 3D 人体心脏。
让它看起来真实：深红色的肌肉，表面有红色动脉和蓝色静脉，内部则是那些你永远没机会看到的部分。四个腔室、四个瓣膜、主动脉和肺动脉、把血液送回来的静脉，以及设定心跳节律的线路。心脏大约每秒跳动一次，瓣膜随之同步开合，血液在其中流动，蓝色流入、红色流出。我可以拖动来环绕它，滚动来缩放。
添加一个 Explode 按钮。我按下它时，每个部件带着名称标签滑开分离。再按一次，所有部件就咔嚓一声重新合拢。当我悬停在某个部件上时，它会亮起，并显示一行说明它作用的内容。
不要用图片。不要问我任何问题。直接做出来。
