Blood interactive worksheet - Free Printable

Let's solve this blood worksheet step by step and explain the answers clearly.

Part 1: Fill in the Blanks

1. The liquid part of blood is called
✔ Plasma
*Explanation:* Blood consists of a liquid component called plasma, which carries cells, nutrients, hormones, and waste products.

---

2. The solid parts of blood are:
✔ Red blood cells, White blood cells, and Platelets
*Explanation:* These are the formed elements of blood that are suspended in plasma.

3. Write RED BLOOD CELL or WHITE BLOOD CELL in response to each statement below.

a. WHITE BLOOD CELL fight any infection that might enter the body.
→ White blood cells (leukocytes) are part of the immune system and defend against pathogens.

b. RED BLOOD CELL contain a pigment called hemoglobin.
→ Hemoglobin is found in red blood cells and binds oxygen.

c. RED BLOOD CELL transport oxygen around the body.
→ This is the primary function of red blood cells.

d. WHITE BLOOD CELL may be phagocytes or lymphocytes
→ White blood cells include various types like neutrophils (phagocytes) and lymphocytes (B and T cells).

e. WHITE BLOOD CELL some engulf germs and destroys them
→ Phagocytic white blood cells (like neutrophils and macrophages) engulf bacteria and other invaders.

f. RED BLOOD CELL looks like a donut from above and the number 8 from the side
→ Red blood cells are biconcave discs—flat with a depression on both sides, giving them a "donut" shape when viewed from above and an "8" shape from the side.

g. WHITE BLOOD CELL some release antibodies to fight germs.
→ B lymphocytes (a type of white blood cell) produce antibodies.

Part 2: Match the Blood Components

We have four images:

1. First image: Small fragments, irregular shapes — these are platelets
2. Second image: Disc-shaped red cell with a central indentation — red blood cell
3. Third image: Irregular, amoeba-like cell — white blood cell (phagocyte)
4. Fourth image: Dark round cell — lymphocyte (a type of white blood cell)

Now let’s match the name and function based on the options given:

| Image | Name of Component | Function of Component |
|-------|-------------------|------------------------|
| 1. Platelets | PLATELETS | HELP BLOOD CLOT |
| 2. Red Blood Cell | RED BLOOD CELL | TRANSPORT OXYGEN |
| 3. White Blood Cell (Phagocyte) | PHAGOCYTE | ENGULF AND KILL GERMS |
| 4. Lymphocyte | LYMPHOCYTES | MAKE AND SEND ANTIBODIES |

> Note: The table provides the following labels:
> - RED BLOOD CELL
> - ENGULF AND KILL GERMS
> - PLATELETS
> - MAKE AND SEND ANTIBODIES
> - HELP BLOOD CLOT
> - LYMPHOCYTES
> - PHAGOCYTE
> - TRANSPORT OXYGEN

So we match accordingly:

#### Final Table:

| NAME OF COMPONENT | FUNCTION OF COMPONENT |
|-------------------|------------------------|
| PLATELETS | HELP BLOOD CLOT |
| RED BLOOD CELL| TRANSPORT OXYGEN |
| PHAGOCYTE | ENGULF AND KILL GERMS |
| LYMPHOCYTES | MAKE AND SEND ANTIBODIES |

---

✔ Summary of Answers:

#### Part 1:
1. Plasma
2. Red blood cells, White blood cells, Platelets
3.
a. WHITE BLOOD CELL
b. RED BLOOD CELL
c. RED BLOOD CELL
d. WHITE BLOOD CELL
e. WHITE BLOOD CELL
f. RED BLOOD CELL
g. WHITE BLOOD CELL

#### Part 2: Matching Table

| IMAGE | NAME OF COMPONENT | FUNCTION OF COMPONENT |
|------|-------------------|------------------------|
| 1 (small fragments) | PLATELETS | HELP BLOOD CLOT |
| 2 (disc-shaped red cell) | RED BLOOD CELL | TRANSPORT OXYGEN |
| 3 (amoeba-like) | PHAGOCYTE | ENGULF AND KILL GERMS |
| 4 (dark round cell) | LYMPHOCYTES | MAKE AND SEND ANTIBODIES |
