Without the skeletal system, the body could not fight off infection. true or false

This is true.

Bones are part of the skeletal system and they have a spongy tissue called bone marrow.

The bone marrow produces different kinds of cells namely red blood cells, platelets and white blood cells.

White blood cells produced include  lymphocytes, neutrophils, and monocytes. These cells are the ones that fight infection - causing agents such as bacteria, viruses or fungi, and destroy them.

Eosinophils help fight parasitic  worms and other large foreign intruders.  They are also produced by the bone marrow.
