More than a red liquid
- Blood looks like a simple red liquid, but it's a mixture of cells and fluid doing many jobs at once.
- It has four main parts.
不只是一种红色液体
- 血液看起来像一种简单的红色液体,但它是一个同时做许多工作的细胞和液体的混合物。
- 它有四个主要部分。
Blood component lab · 血液成分实验
Classify blood components by the job they do. · 根据功能对血液成分进行分类。
Red blood cells carry oxygen using: · 红细胞利用______携带氧气：
Haemoglobin binds oxygen. · 血红蛋白结合氧气。
Red blood cells have no nucleus, leaving more room for haemoglobin. · 红细胞无细胞核，为血红蛋白腾出更多空间。
No nucleus and a biconcave shape suit oxygen transport. · 无细胞核及双凹圆盘形状适合氧气运输。
Red blood cells 红细胞
- Red blood cells carry oxygen, using the red pigment haemoglobin 血红蛋白.
- They have no nucleus and a biconcave 双凹的 shape — more room and surface area for oxygen.
Blood is red cells, white cells and platelets 血小板 carried in liquid plasma 血浆
红细胞
- 红细胞(red blood cells)携带氧,使用红色色素血红蛋白(haemoglobin)。
- 它们没有细胞核,有一个双凹(biconcave)形状——给氧更多的空间和表面积。
血液是携带在液体血浆中的红细胞、白细胞和血小板
White blood cells: · 白细胞：
White blood cells defend against pathogens. · 白细胞防御病原体。
Platelets help to: · 血小板有助于：
Platelets are needed for clotting. · 血小板对凝血至关重要。
White blood cells 白细胞 and platelets
- White blood cells fight pathogens (some engulf them, some make antibodies).
- Platelets are cell fragments that help the blood to clot 凝血 at a wound.
白细胞和血小板
- 白细胞(white blood cells)对抗病原体(有些吞噬它们,有些制造抗体)。
- 血小板(platelets)是帮助血液在伤口处凝结(clot)的细胞碎片。
The liquid part of blood that carries cells and nutrients is . · 血液中携带细胞和营养物质的液体部分是。
Plasma carries cells, nutrients, hormones, waste and heat. · 血浆携带细胞、营养物质、激素、废物和热量。
Plasma
- Plasma is the pale yellow liquid that carries everything: blood cells, nutrients, hormones, waste and heat.
Worked example. A red blood cell's lack of a nucleus leaves more space for haemoglobin, and its biconcave disc shape gives a large surface area — both adaptations for carrying as much oxygen as possible.
血浆
- 血浆(plasma)是携带一切的淡黄色液体:血细胞、营养素、激素、废物和热量。
例题。 一个红细胞缺少细胞核,为血红蛋白留下更多空间,它的双凹圆盘形状给出一个大表面积——两者都是为携带尽可能多的氧的适应。
You've got it
- red blood cells carry oxygen (haemoglobin; no nucleus; biconcave)
- white blood cells fight pathogens; platelets help clotting
- plasma is the liquid carrying cells, nutrients, hormones, waste and heat
你掌握了
- 红细胞携带氧(血红蛋白;没有细胞核;双凹)
- 白细胞对抗病原体;血小板帮助凝结
- 血浆是携带细胞、营养素、激素、废物和热量的液体
