Tendon fibres. Coloured scanning electron micrograph (SEM) of tendon fibres. Some of the fibres have been teased apart. These fibres are made from collagen. The parallel alignment of the fibres make tendons inelastic but flexible. Tendons attach [F0012086] > Stock Photos | Royalty Free | Royalty Free Photos > Visualphotos.com

Nerve cells. Coloured scanning electron micrograph (SEM) of nerve cells, known as neurones. Nerve cells occur in the brain, spinal cord, and in ganglia. Each nerve cell has a large cell body (brown) with several long processes extending from it. The processes usually consist of one thicker axon and several thinner branched dendrites. The dendrites collect information in the form of nerve impulses from other nerve cells and pass it to the cell body.

Blood clot, coloured scanning electron micrograph (SEM). Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (beige). 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.

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.
