This card explains oxygen transport into insect cells via diffusion through tracheal fluid and how this fluid recedes during increased oxygen demand.
Tato karta vysvětluje transport kyslíku do buněk hmyzu pomocí difúze přes trachoelový fluid a popisuje, jak se tento fluid odebírá při zvýšené potřebě kyslíku.
| Front | Tracheal system, O2 into cells and tracheal fluid 3.1.1(f) |
|---|---|
| Back | - mostly diffusion, is here O2 dissolves in moisture of tracheole walls to diffuse into surrounding cells - teacheal fluid towards end of tracheoles (limiting penetration of air for diffusion), so when O2 demands inc, lactic acid builds up in tissues, fluid moves out of tracheoles (osmosis) so more SA for gas exchange |
