pancreas, (kokuji)
膵 is a Japanese-made kokuji that refers specifically to the pancreas, an organ in the body.
膵 is a kokuji created in Japan by combining the flesh/organ component ⺼ with 萃, which likely contributes the sound スイ. The character was coined to represent the pancreas.
The left side ⺼ (flesh/organ) and the right side 萃 (which can mean 'gather') together suggest a gathering of flesh: the pancreas, a distinct organ.
For スイ, imagine a sweet (スイーツ) pancreas-shaped dessert: sweet -> スイ, and the organ is the pancreas.
