Stone, Wellcome Images SEM of blood vessel in a melanoma - coloured - A colour-enhanced, freeze-fracture scanning electron micrograph of a blood vessel that has grown into a melanoma and is providing nourishment to it. Numerous red blood cells and three white blood cells can be seen within the blood vessel.

fuckyeahmolecularbiology:

Coloured scanning electron micrograph (SEM) of an elastic artery cross-section. The cross-section was taken from a small elastic artery originally from a human lung. The lumen contains red blood cells (red) and platelets (yellow). In the wall of the blood vessel, a clear internal elastic lamina (pale purple) is visible. This elastic lamina gives rise to the Windkessel effect, which helps to maintain a relatively constant pressure in the arteries despite the pulsating nature of the blood flow.

scanning electron microscopy of blood cells…fuck yeah

micro-scopic:

Neutrophils. Coloured scanning electron micrograph (SEM) of neutrophils, a type of white blood cell (leucocyte). These cells are phagocytic, in that they engulf and digest materials from their surroundings. These cells contain enzymes that are used to digest invading bacteria. They are highly mobile, migrating to areas of tissue damage within the body. Magnification: x2500 at 6x7cm size.

THESE SOME GREAT REAL PICTURES OF YOUR IMMUNE CELLS. ALL OF THEM ARE CIRCULATING IN YOUR BODY AND WORKING 24/7 TO PREVENT YOU FROM GETTING INFECTION AND FALL SICK. ^^

AREN’T YOU AMAZED BY THESE? WELL, I AM.
