Lymphatic System淋巴系统

Place · Level 3

第二套排水管 + 免疫高速路 · 靠肌肉和呼吸推动 · 会流, 但不排毒

Your second plumbing

Stop 1/6

身上的第二套管道

You actually have two plumbing networks. One is the blood vessels, with the heart as its pump, sending blood everywhere. The other most people have never heard of — the lymphatic system — and it has no pump; it quietly collects fluid and moves immune cells through the gaps between your tissues.

Where it is: next to almost every inch of tissue that has blood vessels there are lymphatic capillaries; the lymph nodes you can feel in your neck, armpit, and groin are its relay stations; the spleen, thymus, and the whole wall of your gut are also its territory.

It has just two real jobs: returning the extra fluid in your tissues back to the blood, and serving as the immune system's highway and checkpoints. Hold onto these two — everything below is just those two in detail.
