killer T cells attack a cancer cell.

The Wars Within

Frozen in action, killer T cells appear remarkably alive as they attack a cancer cell. Several of the normally round T-cells acquire the elongated shape of active fighters as they subject their target to chemical attack, breaking down the cell membrane.

A Few Kidney Facts: higher blood flow than even the brain, liver or heart, reabsorb and redistribute 99% of the blood volume and only 0.1% of the blood filtered becomes urine, Each kidney is about 4 ½ inches long, weighs approximately 4 to 6 ounces, kidneys of a newborn baby are about 3X larger in proportion to body weight, volume of urine excreted daily approx 1000 to 2000 mL.

Each kidney contains thousands of glomeruli, tiny knots of blood vessels that filter large molecules out of urine. Fractal branching patterns in the circulation of blood inside the kidney ensure that the filtration process is as efficient as possible.

Cancer migrating SEM. Cancer moving (Metastasising) through a hole in a support film.

Coloured SEM of a cultured cancer cell moving through a hole in a support film. Numerous pseudopodia, fillipodia and surface blebs can be seen and are characteristic of highly mobile cells which enable them to metastasise rapidly.

Brain lining. Coloured scanning electron micrograph (SEM) of the lining of the brain, showing the ciliary hairs (orange) of ependymal cells. Ependymal cells are a type of neuroglia (glial cells) that line the ventricles of the brain and produce cerebrospinal fluid (CSF). CSF has a number of functions, including buffering the brain from shock, transporting hormones around the brain and absorbing waste products. The ciliary hairs are used to help circulate the CSF.

Bone marrow, coloured scanning electron micrograph (SEM). This freeze-fracture has revealed the cavity (lumen) of a large venous sinus (pink), which contains mature blood cells (red), and developing white blood cells (blue). Either side of the sinus are the haemopoetic foci of the marrow (green). Magnification: x3000 when printed at 10 centimetres across | Steve Gschmeissner
