Arteriole blood cells. Illustration of blood cells emerging (at bottom) from an arteriole,a small branch of an artery. Various blood cell types are seen: red cells (erythrocytes) are carriers of oxygen; white cell monocytes or macrophages (blue) are,with neutrophils (pink,multi-lobed nucleus),cells that fight infection; much smaller platelets of different size and shape are responsible for blood clot formation. The arteriole wall is one cell thick,with semi-circular cells (red) suppor- ting and strengthening the wall. Fibroblast (yellow) cells are connective tissue secretory cells which help to support arterioles and nerve fibres (blue) within the vertebrate body | |
