单词	vein
释义	Definition of vein in English: vein noun veɪnveɪn 1Any of the tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood towards the heart. 静脉。比较ARTERY Compare with artery Example sentencesExamples Such a clot will move to the heart along the main vein of the body, the inferior vena cava. The thoracic duct was identified, lying between the right azygous vein and the descending aorta just in front of the spine. The pulmonary veins are big veins that come from the lungs and take the blood from the lungs back into the heart. Just behind the mitral valve, there is a vein called the coronary sinus, a large vein in the heart that normally drains all of the blood from the coronary arteries. The inferior thyroid, and intercostal bronchial, gastric, and phrenic veins provide venous drainage. The veins merge to carry blood to the inferior vena cava. Tumor infiltration of leptomeningeal veins, cranial nerves, and spinal roots was also noted. If the embolus is in a vein, the tube system widens along the direction of the blood flow, so a small embolus doesn't do much harm until it gets through the heart (after which it enters an artery). They happen when the valves in the veins become weak or break, allowing blood to collect in the veins instead of being carried up to the heart. Rarely the tumor may involve the renal vein, vena cava, and extrarenal soft tissues. It is rare to find a simple right lymphatic duct that enters directly into the junction of the internal jugular and subclavian veins. An aortogram shows opacification of pulmonary arteries, veins and right atrium as well as the aorta. Blood from all parts of the body returns through veins to the right atrium (grey arrows). The veins around the anus drain into larger veins that carry the blood through the liver and up to the heart. The larvae enter the veins of the portal system and are carried to the liver.

Each wall in each alcove had detailed plants and flowers, each plant's leaf had carefully carved veins.

Plants show similar repetitive structures in, for example, the veins on a leaf or a tree's branching limbs. Most plants have leaves with veins that fork outward from a central midrib. It is worse among leaves with prominent veins where small air channels may form between the gasket and the sides of the vein. Expression was also detected in stamens, in cotyledons, and in major veins of some mature leaves. The leaves of the plant are rough from numerous stiff hairs while the veins of the leaf have a blackish tinge that produces a characteristic shadowy complexion to the foliage. Long hairs are situated on veins and glandular trichomes occur both on the leaf surface and veins. One leaf disc with known area was detached from each leaf, avoiding major veins and the midrib.

The anterior wing margin, delimited by the L1 wing vein, is composed of a triple row of sensory bristles.

Copper also filled voids and occurred in thin fissure veins that cut the lodes. The granite rocks of the glacial valley contain quartz veins of silver, lead and zinc and at one time there were over 2 000 miners toiling there. Quartz is the dominant mineral in veins in siliceous rocks, calcite in limestones, and gypsum in gypsiferous sediments. The calcite acts as a mask, obscuring the gold-bearing veins from the predominate ones that contain nothing. The order of deposition for the main vein minerals typically is dolomite, barite, and quartz. Hushing, for example was the technique of using water to wash away the soil and surface debris to reveal the vein of mineral below and it was used extensively in the Dales. Gold occurs in quartz veins with chalcopyrite, galena, pyrite, and sphalerite. There are two kinds of tungsten deposits: wolframite in quartz veins and in scheelite skarn. These features include veins, fold-related fractures, cleavage and cleavage/bedding intersections.
