| fenestrated capillary | A capillary, found in renal glomeruli, intestinal villi, and some glands, in which ultramicroscopic pores of variable size occur; usually these are closed by a delicate diaphragm, although diaphragms are lacking in at least some renal glomerular capillary's.

|---|---|
| fenestrated | <botany> A type of leaf anatomy with small perforation or transparent spots. Confined to a few tropical monocotyledons which grow on the island of Madagascar. (09 Oct 1997) |
| fenestrated membrane | An elastic membrane, as in elastic laminae of arteries. (05 Mar 2000) |
| fenestrated sheath | A sheath with a window cut in the tip or lateral convexity, through which special cutting instruments can be passed. (05 Mar 2000) |
| arterial capillary | A capillary opening from an arteriole or metarteriole. (05 Mar 2000) |
| bile capillary | One of the intercellular channels, about 1 um or less in diameter, that occurs between liver cells forming the first portion of the bile system. Synonym: bile capillary. (05 Mar 2000) |
| blood capillary | A vessel whose wall consists of endothelium and its basement membrane; its diameter, when the capillary is open, is about 8 um; with the electron microscope, fenestrated capillary's and continuous capillary's are distinguished. (05 Mar 2000) |
| capillary | <anatomy> Any one of the minute vessels that connect the arterioles and venules, forming a network in nearly all parts of the body. Their walls act as semipermeable membranes for the interchange of various substances, including fluids, between the blood and tissue fluid. Synonym: vas capillare. Origin: L. Capillaris = hair like (16 Dec 1997) |
| capillary action | The phenomenon of a liquid such as water spontaneously creeping up thin tubes and fibres, this is caused by adhesive and cohesive forces and surface tension. (09 Oct 1997) |
| capillary angioma | <dermatology> Red or purple-coloured vascular skin markings that develop shortly after birth. Most are usually painless and benign and sharply demarcated from surrounding skin, usually located on the head and neck, and grow rapidly. It is caused by proliferation of immature capillary vessels in active stroma, and is usually present at birth or occurs within the first two or three months of life. Some lesions (cavernous haemangioma) will disappear or become harder to see as the child approaches school age. Localised steroid injections have been used successfully to reduce the size of a birthmark but generally they undergo spontaneous regression and involution without scarring and normally require no treatment.

| capillary arteriole | A minute artery that terminates in a capillary. (05 Mar 2000) |
| capillary attraction | The force that causes fluids to rise up very fine tubes or through the pores of a loose material. (05 Mar 2000) |
| capillary bed | The capillaries considered collectively and their volume capacity for blood. (05 Mar 2000) |
| capillary circulation | The course of the blood through the capillaries. (05 Mar 2000) |
| capillary drainage | Drainage by means of a wick of gauze or other material. (05 Mar 2000) |
