水肿是老年人的一种常见症状,老年人水肿应考虑哪些疾病呢?首先我们来认识一下水肿是怎样形成的。 在正常人体中,血管内的液体不断地从毛细血管小动脉端滤出至组织间隙成为组织液,供给组织的各种营养物质;另一方面组织液又不断从毛细血管小静脉端回吸入血管中,将组织中的代谢废物带至肾脏排出体外。二者经常保持动态平衡,因而组织间隙无过多的液体积聚。当这种平 Edema is a common symptom of the elderly, the elderly should consider what disease edema? First of all, let us know how the formation of edema. In normal human body, the fluid in the blood vessel is continuously filtered out from the arteriolar end of the capillaries to the interstitial space to become the tissue fluid, which supplies various nutrients of the tissue. On the other hand, the interstitial fluid continuously sucks back into the blood vessel from the capillary venules, The organization of metabolic waste brought to the kidneys excreted. The two often maintain a homeostasis, so there is no excess tissue interstitial fluid accumulation. When this kind of flat
