placental barrier(胎盘屏障)是母体与胎儿之间的一种选择性物质交换及免疫保护结构,其详细解释如下:
定义与组成 胎盘屏障由绒毛血管壁、绒毛间质、基底膜和绒毛上皮共同构成。这种多层结构将母体与胎儿的血液循环系统分隔开,形成物理性隔离。
核心功能
重要性:胎盘屏障对胎儿发育至关重要,其功能异常可能导致流产、早产或胎儿发育缺陷。在医学研究中,该结构也是药物妊娠安全性评估的重点。
Placental Barrier是指胎盘屏障,是指母体和胎儿之间的一层屏障,起到了保护胎儿免受母体内的有害物质侵害的作用。下面是该词的详细解释:
名词
Placental Barrier是生物学和医学领域常用的术语,用于描述胎盘屏障的作用和功能。在科学文献和医学报告中,该词经常被提到。
Placental Barrier是由胎盘组织构成的,能够阻止母体中的某些物质通过胎盘进入胎儿的血液循环系统。这些物质可能包括病毒、细菌、毒素和药物等。胎盘屏障的主要组成部分是绒毛和羊膜,它们与母体的血液循环系统隔离开来,只有少量物质能够穿过这层屏障。
