    Cryptosporidium protozoa

    Bone marrow stem cell, SEM

    Cervical cancer cells. Wow.

    Golgi apparatus in a cell.

    Leishmania Protozoa

    Staphylococcus aureus

    Giant Liposomes. Where a liiposome is: "a minute spherical sac of phospholipid molecules enclosing a water droplet, esp. as formed artificially to carry drugs or other substances into the tissues."

    Human chromosomes and nucleus, coloured scanning electron micrograph (SEM). Chromosomes are a packaged form of the genetic material DNA (deoxyribonucleic acid). The DNA normally exists in a non-condensed form in the cell nucleus (upper right). It condenses into chromosomes (centre and lower left) during cell replication. In humans, there are 46 chromosomes, consisting of 23 chromosome pairs. Magnification: x4350 when printed at 10 centimetres across.

    Goblet cells- they make your mucous.

    An image of capillary, just wide enough for one red blood cell (erythrocyte) to squeeze through.

    Kidney cortex, showing numerous glomeruli with their afferent and efferent arterioles and the peritubular capillary complexes.

    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.

    Diatom. Coloured scanning electron micrograph (SEM) of a Triceratium sp. diatom.

    Nerve cells, artwork

    Immune system fighting a cancer cell. A killer T-lymphocyte (orange) inducing a cancer cell to undergo Programmed Cell Death.

    SEM image of blood clot

    Sciatic nerve. The sciatic nerve is the longest and widest single nerve in the human body, running from the top of the leg to the back of the foot

    Ruptured venule. Colored (SEM) showing stacks (rouleaux) of red blood cells exposed inside a torn venule.

    Bacteria strep throat! LOL

    Myelinated nerves. A section through myelinated nerve fibers and Schwann cells. Myelin (green) is an insulating fatty layer that surrounds the nerve fibre (axon, black), increasing the speed at which nerve impulses travel.
