红细胞俗称红血球,是血液中主要的有形成分,日夜不停地周游全身。负担全身各组织细胞氧与二氧化碳交换,并参与机体免疫功能。在一般人心目中大多数认为红细胞必然是球形、圆的,其实红细胞形态在人体内经常在发生变化,这种变化称为红细胞变形性(能力)。正因为存在这种变形性,才能适应不同部位、不同形状、不同直径的血管网。 红细胞具有弹性,当血流静止或缓慢移动时则呈双凹面的圆盘状,随着血流速度变化可变为各种形状。当血流在毛细血管中高速通过时则变成弹头状,尾部如降落伞向内凹陷,以便随时调整其长短粗细。红细胞这种变形性从表面看似乎是一种物理现象,但这种变形性的改变可能与多种疾病有着因果关
Red blood cells, commonly known as red blood cells, are the major tangible components in the blood and travel around the body day and night. Burden all body tissues of oxygen and carbon dioxide exchange, and participate in immune function. Most people in the minds of most people think that red blood cells must be spherical, round, in fact, the red blood cell morphology is often changing in the human body, this change is called red cell deformability (ability). Because of this deformability, can adapt to different parts, different shapes, different diameter vascular network. Erythrocytes are flexible, have a biconcave disk shape when the blood flow is still or slowly moving, and change to various shapes as the blood flow velocity changes. When the blood flow through the capillaries at high speed will become a bullet-like tail, such as a parachute inward depression, in order to adjust the length and shortness of the thickness. This deformability of erythrocytes seems to be a physical phenomenon on the surface, but this change in deformability may have a causal relationship with various diseases
