Bloedstolsel kristallen Het lichaam is echt geweldig. Kunnen vormen stolsels via de kristallen om het bloeden te stoppen. Wow. Bloedstolsel kristallen. Gekleurde scanning elektronenmicroscoop (SEM) van kristallen van albumine van een bloedstolsel. Wanneer de huid wordt gesneden, worden kleine bloedvaten gescheurd, vrijgeven bloed. Sommige eiwitten in het bloedplasma (zoals albumine) harden in de lucht kristallen (roze) over de wond te vormen. Credit: STEVE GSCHMEISSNER / ...

Zoutkristallen in verdampt zout water

Fertilization. Colored scanning electron micrograph (SEM) of a sperm (blue) attempting to penetrate a human egg (orange).


Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.


Retina. Coloured scanning electron micrograph (SEM) of rods (yellow) and cones (green) in the retina of the eye. The outer nuclear layer is purple. Magnification x1800 when printed at 10 centimetres wide. [F0010041] Incredible!!


Ruptured capillary. Coloured scanning electron micrograph (SEM) of a red blood cell squeezing out of a torn capillary. A capillary is the smallest type of blood vessel, often only just large enough for red blood cells to pass through. Red blood cells (erythrocytes) are biconcave, disc-shaped cells that transport oxygen from the lungs to body cells. Credit: STEVE GSCHMEISSNER/SCIENCE PHOTO LIBRARY


Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.


Colored scanning electron micrograph of the blood vessels coming from the optic disc. Way cool.
