管径最细、分布最广、连接微动脉和微静脉的血管
Capillaries are the tiniest blood vessels in your body, measuring just 5 to 10 micrometers across, and they form the final connection between arteries and veins. They matter because their extremely thin walls allow oxygen, nutrients, and other substances to pass between your blood and the surrounding tissues, making them essential for keeping your cells alive.

{{namespace detect | category = |main=| other= 循環系統 微血管 微血管（capillary）又称为毛細血管，連接最小的動脈與最小的靜脈，是由動脈分支為較小的動脈，再分支多次的血管。 微血管是管壁最薄的血管，只有一上皮细胞构成，利於血液與組織細胞之間物質的交換。微血管平均管径为6至9微米，血液流速为主动脉的1/800；血壓則是居於動脈及靜脈之間。 微血管的主要功能在於物質的交換：在肺微血管中，因微血管的氧氣濃度小於肺泡中的濃度，氧氣透過擴散作用進入微血管中，由紅血球中的血基質運送至體內的組織細胞；而二氧化碳濃度高於肺泡中的濃度，二氧化碳透過擴散作用排出微血管，回到大氣。在其他部位的微血管，因微血管中氧氣濃度高於組織細胞中的濃度，氧氣透過擴散作用進入組織細胞中；而二氧化碳濃度低於組織細胞中的濃度，二氧化碳透過擴散作用進入微血管，送至肺泡排出體外。
