[00:00:02]Bone marrow niches located deep within the spongy interior of your bones.

[00:00:07]Inside these hidden spaces, new blood cells are constantly being created [music] and carefully controlled. Red cells carry oxygen, white cells fight infection, and platelets help stop bleeding. This process runs silently every second, keeping your body alive and balanced. When it fails, even simple functions [music] become dangerous. You never feel it happening, but your survival depends on this invisible system.
