Here’s the complete solution to both matching tasks, with clear explanations:

##
✔ Part 1: Match each blood component to its correct picture
We have 4 images and 4 labels. Let’s identify each image:
1.
First image (leftmost) — A large, irregularly shaped cell with a visible nucleus.
→ This is a
White blood cell (leukocyte). They are larger than other blood cells and have complex shapes for fighting infection.
2.
Second image — A test tube showing separated layers of blood. The top yellowish layer is
plasma.
→ This represents
Blood Plasma — the liquid portion of blood that carries cells and proteins.
3.
Third image — Many small, spiky, star-like fragments floating in fluid.
→ These are
Blood platelets (thrombocytes). They’re not full cells but fragments that help clot blood.
4.
Fourth image (rightmost) — A smooth, biconcave disc-shaped red cell.
→ This is a
Red blood cell (erythrocyte). Its shape maximizes surface area for gas exchange.

📌 Correct Matching for Part 1:
-
Image 1 →
White blood cells
-
Image 2 →
Blood Plasma
-
Image 3 →
Blood platelets
-
Image 4 →
Red blood cells

✔ Part 2: Match each blood component to its correct function
Let’s match each component to its biological role:
1.
Blood platelets
→ Function:
Coagulation of the blood.
*Explanation:* Platelets clump together at injury sites to form clots and stop bleeding.
2.
White blood cells
→ Function:
Defend the body by attacking the microbes.
*Explanation:* WBCs are part of the immune system — they identify and destroy pathogens like bacteria and viruses.
3.
Red blood cells
→ Function:
Carry oxygen and carbon dioxide.
*Explanation:* RBCs contain hemoglobin, which binds oxygen in the lungs and releases it in tissues; they also carry CO₂ back to the lungs.
4.
Plasma
→ Function:
Carry digested food and wastes.
*Explanation:* Plasma is the liquid matrix that transports nutrients (like glucose, amino acids), hormones, proteins, and waste products (like urea) throughout the body.

📌 Correct Matching for Part 2:
-
Blood platelets →
Coagulation of the blood.
-
White blood cells →
Defend the body by attacking the microbes.
-
Red blood cells →
Carry oxygen and carbon dioxide.
-
Plasma →
Carry digested food and wastes.

✔ Final Answer Summary:
Picture Matching:
- Image 1 → White blood cells
- Image 2 → Blood Plasma
- Image 3 → Blood platelets
- Image 4 → Red blood cells
Function Matching:
- Blood platelets → Coagulation of the blood.
- White blood cells → Defend the body by attacking the microbes.
- Red blood cells → Carry oxygen and carbon dioxide.
- Plasma → Carry digested food and wastes.
