I found it possible to observe at least the superficial capillaries of muscles both in the frog and in mammals through a binocular microscope, using strong reflected light as a source of illumination. Resting muscles observed in this way are usually quite pale, and the microscope reveals only a few capillaries at fairly regular intervals.

Every glass thermometer has subtle variations in the size and shape of the bulb at the bottom and the capillary tube inside, as well as variations in the width of gradations on the side. The compounded effect of these uncertainties is that each thermometer reads temperature slightly differently.

Since muscular contractions are usually more or less regularly alternated with relaxations, the system of valves makes of the veins of every muscle a very effective pump, capable of maintaining a low pressure in the muscle capillaries.

Dead bodies do get a grayish blue/purple hue because blood pools in the capillaries and the body starts to decompose. It's not smurf blue, but it's not a pleasant shade.

Games is like hardwired plumbing in the house of pop. It's not pop itself, its sort of like the behind-the-scenes arteries and capillaries of pop music.

Capillaries are extremely small and not visible to the naked eye.

Microscopic Scale

Capillaries are crucial for oxygen delivery from arteries to the body's tissues.

Oxygen Transport

Capillaries are the site where substances are exchanged between blood and tissues.

Capillary action is a property where liquid moves through narrow spaces against gravity.

Scientific Phenomenon

Plants rely on capillary action to transport water from roots to leaves.

Botanical Understanding

Capillary tubes are used to handle very small volumes of liquid with accuracy.

Precision Instrument

Some thermometers, like those for the body, use capillary tubes with mercury or alcohol.

Temperature Measurement

Understanding how to use a capillary tube is a basic lab skill in many scientific fields.

 that are surrounded by capillaries. Together, the alveolar wall and capillaries make a two-cell thick membrane that brings blood and oxygen close enough for diffusion. These oxygen-enriched cells are then carried from the lungs through the cardiovascular network,

 So blood shift -- how does it work? The capillaries in the lungs become engorged with blood -- which is caused by the suction -- so the lungs can harden and protect the whole chest cavity from being crushed. It prevents the two walls of the lungs from collapsing,

 End to end, that would form a line that would circle the earth twice. The smallest blood vessels are called capillaries. We've got 19 billion of them in our bodies. And these are the vessels of life, and as I'll show you, they can also be the vessels of death.

 that prevents your blood from clotting. That compound, which we're mildly allergic to, triggers the release of histamine, a chemical that makes our capillaries swell. This enables increased blood flow, which helpfully accelerates the body's immune response

 Eventually, these accumulated layers start to bend under pressure, causing deep cracks to form in between the papillae. Water then flows through the crevices using capillary action,
