So, asyoucansee, wehave a tinylittlebloodvesselherecalled a capillary.
ご覧のように、ここには毛細血管と呼ばれる小さな血管がある。
Andinsidethecapillary, youhavethiscellrepresenting a whitebloodcellcalled a neutrophil, whichisdoingthisreallycoolroly-polyprocessthatwe'llgetintoduringthenextstep, andwe'llfindthatit's notreallycalledtheroly-polyprocess.

それほどまでに、私たちは実際に、組織に送られる白血球部隊の第二波を持っている。
Within a fewdaysofinflammationstarting, a whitebloodcellknownas a monocytewillcomefromthebloodandenterintotheinflamedtissue.
炎症が始まって数日以内に、単球と呼ばれる白血球が血液からやってきて、炎症組織に入り込む。
Now, youmightbethinkingthismonocyteis a completelynewcell.
さて、この単球はまったく新しい細胞だと思うかもしれない。
Butyouhavemetthiscellbefore, butin a differentform.
しかし、この細胞には以前にも会ったことがあるはずだ。
