Do larger people have larger organs?

I'm an above average male, 6 foot 7 inches and 240ish pounds. Are my internal organs like my liver or heart significantly larger than someone like my s/o who is 5 foot 5 inches and 130 pounds?

Yes. It all starts with your skeleton. A larger frame needs larger muscles to move it. Larger muscles will need more nourishment. This leads to a larger digestive tract and a circulatory system with more volume. A larger circulatory system has more RBC's which need a larger spleen to filter them, has more fluid which needs larger kidneys to filter it, and carries more oxygen which needs larger lungs to supply it. Of course, all your RBC's are made in your bone marrow, which needs to be larger to make them, which completes the circle.

That's the logic behind it, but the real reason is simply that your growth hormones act in equal proportions on all of the parts of your body.
