两肺之间是什么？What sits between your lungs?
在三维中观察一个来自人体参考图谱的胸腔。转动躯干，在体表打开一个观察窗，看清正面平视时容易被遮住的空间关系。
Inspect an atlas-derived human chest in three dimensions. Rotate the torso and open a window in its body surface to see relationships that a flat front view can hide.
01预测排列Predict the arrangement
02看进去Look inside
打开胸腔观察窗，选中心脏，再转到侧面。如果肺挡住了你想看的结构，可以把肺隐藏。
Open the chest inspection window. Select the heart, then turn toward a side view. Hide the lungs if they block the structure you want to inspect.

两肺位于胸腔内心脏的两侧。左肺略小，因为心脏在左侧占据了一部分空间。膈肌是位于肺下方的穹顶状肌肉，把胸腔和腹腔分开。
转动或隐藏某个结构只改变你能看到什么，不会把器官移到体内的新位置。
The lungs sit on either side of the heart in the chest. The left lung is slightly smaller because the heart takes up some space on the left. The diaphragm is a dome-shaped muscle below the lungs that separates the chest cavity from the abdominal cavity.
Rotating or hiding a structure changes visibility. It does not move an organ to a new position inside the body.

来源、改动与边界Sources, changes and limits
几何与改动。体表、肺段、气管支气管树和心脏表面来自 Human Reference Atlas / HuBMAP Visible Human 男性参考模型，采用 CC BY 4.0 许可。固定版本的源模型保留了共同坐标和相对比例。本衍生版把皮肤裁成胸像、降低了网格密度、量化了坐标并更换了显示颜色。躯干裁切处留有可见的开口边界。观察窗只移除体表，不是手术切口。金色膈肌是示意性的穹顶，不是图谱网格。
渲染选择。图谱网格提供有机的解剖形态；原生 WebGL 提供平滑法线和深度测试遮挡。Anatomy 工具包贡献了检视方式，本技能贡献了“预测—检视—解释”的课程结构；Anatomy 工具包并不提供人体器官几何。
范围。这是参考人体的教学视图，不针对具体患者。没有模拟呼吸、血流或临床判断。关系的来源：NHLBI，呼吸系统 · NHLBI，呼吸肌 · NHLBI，心脏解剖。网格已内嵌，可离线使用；来源链接需要联网。
Geometry and changes. Body surface, lung segments, tracheobronchial tree and heart surfaces are derived from the Human Reference Atlas / HuBMAP Visible Human male reference objects, licensed CC BY 4.0. Pinned source models retain their shared coordinates and relative scale. This derivative crops the skin to a bust, reduces mesh density, quantizes coordinates and changes display colors. The torso crop has visible open boundaries. The inspection window removes body surface only; it is not a surgical cut. The gold diaphragm is an illustrative dome, not an atlas mesh.
Rendering choice. Atlas meshes provide the organic anatomy. Native WebGL supplies smooth normals and depth-tested occlusion. Anatomy contributes the inspection approach and the fused skill contributes the predict, inspect and explain lesson; the Anatomy skill does not supply human organ geometry.
Scope. A reference-body teaching view, not patient-specific anatomy. No breathing, blood flow or clinical interpretation is simulated. Sources for the relationships · NHLBI, The respiratory system · NHLBI, Breathing muscles · NHLBI, Heart anatomy. The mesh is embedded and works offline; source links require a connection.

胸腔三维视图3D chest view
患者的左右随躯干一起转动。正面视图中，患者的左侧在你的右边。图谱几何保留源模型的比例与位置；颜色只用于区分结构，不是组织的真实颜色。金色膈肌是示意性的教学叠加层。Patient left and right rotate with the torso. At the front view, the patient's left is on your right. Atlas geometry preserves the source proportions and positions. Colors distinguish structures; they are not tissue colors. The gold diaphragm is a schematic teaching overlay.
