Final Answer:
Red blood cells: Carry oxygen; White blood cells: Fight infection; Platelets: Help clot blood; Plasma: Liquid part carrying cells and proteins.
──────────────────────────────────────
Explanation:
Let’s go row by row using the pictures:
1. First picture (red disc): That’s a red blood cell.
→ It carries oxygen from your lungs to your body.
→ It’s shaped like a donut (no hole in middle) so it can squeeze through tiny blood vessels.
→ If you don’t have enough, you get anemia — you feel tired and pale.
2. Second picture (big irregular shape): That’s a white blood cell.
→ It fights germs and keeps you from getting sick.
→ It has lots of ribosomes (tiny machines that make proteins) to build antibodies and enzymes to kill germs.
→ In AIDS, these drop way down — that’s why people get sick easily.
3. Third picture (small pieces): Those are platelets.
→ They stick together to stop bleeding when you get a cut.
→ They’re like tiny band-aids inside your blood.
4. Fourth picture (yellow liquid with red at bottom): That’s plasma.
→ It’s the liquid part of blood — mostly water.
→ It carries all the cells, nutrients, hormones, and waste around your body.
Now for the questions:
1. Anemia symptoms: Tiredness, dizziness, pale skin, shortness of breath — because not enough oxygen is reaching your body.
2. White blood cell drop:
Normal = 8500 per microliter
AIDS patient = 680 per microliter
Decrease = 8500 – 680 = 7820
Percentage decrease = (7820 ÷ 8500) × 100 = 92% decrease.
3. Why white blood cells have lots of ribosomes?
→ Because they need to make lots of proteins (like antibodies) to fight germs fast.
4. Where new red blood cells are made?
→ In your bone marrow (soft stuff inside big bones like hips and ribs).
→ Lifespan is 120 days — then old ones die and new ones replace them.

Teach the Topic:
Blood is like a delivery truck system inside your body. It has 4 main parts:
1. Red blood cells = Oxygen carriers. They pick up oxygen in your lungs and drop it off everywhere else. No oxygen = no energy!
2. White blood cells = Body guards. They hunt and destroy bacteria, viruses, and other invaders. Think of them as soldiers.
3. Platelets = Emergency repair crew. When you get a cut, they rush to plug the hole and stop bleeding.
4. Plasma = The liquid highway. It’s what everything floats in. It also carries food, hormones, and trash out of your body.
Simple example:
Imagine your body is a city.
- Red blood cells = Delivery vans bringing oxygen packages.
- White blood cells = Police cars chasing bad guys (germs).
- Platelets = Road repair trucks fixing broken pipes (blood vessels).
- Plasma = The roads and streets the vehicles drive on.

Practice Task:
Complete this simpler table:
| Component | Picture (describe) | Function (what it does) |
|----------------|--------------------------|------------------------------|
| Red blood cell | Round, red, no nucleus | ___________________________ |
| White blood cell | Big, blobby, with nucleus | ___________________________ |
| Platelet | Tiny, grain-like | ___________________________ |
Bonus question:
If normal red blood cells are 5 million per microliter and someone has 3 million, what’s the percentage decrease?
Red blood cells: Carry oxygen; White blood cells: Fight infection; Platelets: Help clot blood; Plasma: Liquid part carrying cells and proteins.
