血細胞 Blood Cells

對于醫(yī)學生來說，進行醫(yī)學英語學習是非常有必要的，因為在工作中會涉及到很多國內外的最新醫(yī)學信息。下面是小編整理的血細胞 Blood Cells的資料，希望對你有所幫助！

血細胞 Blood Cells

　　血細胞

　　Blood cells, which can be seen under a microscope, make up about 40% of the blood's volume. Blood cells are made in the bone marrow by blood 'stem' cells. Blood cells are divided into three main types.

　　血細胞（血球）。從顯微鏡中觀察，血細胞占軀體容量的40%左右，由骨髓中的血“干”細胞生成。血細胞可分成三大類：

　　Red cells (erythrocytes). These make blood a red colour. One drop of blood contains about five million red cells. Red cells contain a chemical called haemoglobin. This binds to oxygen, and takes oxygen from the lungs to all parts of the body. form www.med66.com

　　紅細胞（紅血球）。紅細胞使血變紅。一滴血約含500萬紅細胞。紅細胞含有一種化學物質，叫血紅蛋白，它與氧氣結合，將氧氣從肺部輸送到全身各部分。

　　White cells (leucocytes). There are different types of white cells such as neutrophils, lymphocytes, eosinophils, monocytes, basophils. They are a part of the immune system and are mainly involved in combating infection.

　　白細胞（白血球）。白細胞分多種，如嗜中性粒細胞、淋巴細胞、嗜酸性細胞、單核細胞和嗜堿粒細胞等。為免疫系統(tǒng)一部分，其主要作用是抗感染。

　　Platelets. Platelet is a minute, irregularly shaped, disklike cytoplasmic body found in blood plasma that promotes blood clotting and has no definite nucleus, no DNA, and no hemoglobin. It is also called thrombocyte.

　　血小板：血小板為血漿中一小形、不規(guī)則形、盤狀細胞質，可促進血液凝固，無細胞核，無DNA，也不含血紅素。又稱凝血細胞。
