2025 newtalk 國中生物 單元四 : 紅色生命之泉-血液

from 雷比特生物空中講 · host 雷比特老師

詳細介紹血液作為一種流動的結締組織的構成與功能,從歷史上的誤解談起,直到雷文霍克的顯微鏡發現。將血液比喻為城市的「超級物流系統」與「機動保全大隊」,並依據離心後的結果,將血液組織分為兩大部分進行深入闡述。血漿(Plasma)作為黃色的液體基質,主要由水組成,並含有白蛋白、球蛋白(即抗體)和纖維蛋白原等重要的血漿蛋白,負責運輸和調節滲透壓。血球(Formed Elements)則涵蓋了擔任「氧氣外送員」且數量最多的紅血球、負責免疫防禦的五種白血球軍團(如嗜中性球與淋巴球),以及負責凝血止血的血小板,最後強調了維持血液組成的恆定(Homeostasis)對於生命的重要性。 聽完後可以自主進行線上測驗,檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/0fec2de0ddef Powered by Firstory Hosting
