I'll work through each question step by step to provide accurate answers.

Question 1: Three major components of blood
Blood consists of three main parts:
- Red blood cells (carry oxygen)
- White blood cells (fight infection)
- Plasma (liquid part that carries everything)

Question 2: Process to stop bleeding
When we get a cut, the body stops bleeding through a process called coagulation or clotting. The more common term is "blood clotting" or simply "clotting."

Question 3: Component containing clotting factors
Clotting factors are proteins found in plasma. These factors work together to form clots and stop bleeding.

Question 4: Disease where clotting factors are absent
When clotting factors are missing or don't work properly, it causes hemophilia. This is a genetic disorder where blood doesn't clot normally.

Question 5: Liquid part of blood
The liquid portion of blood is called plasma. It makes up about 55% of blood volume and carries cells, nutrients, hormones, and waste products.

Question 6: Five types of white blood cells
The five types of white blood cells (leukocytes) are:
- Neutrophils - fight bacteria
- Lymphocytes - fight viruses and make antibodies
- Monocytes - become macrophages that eat debris
- Eosinophils - fight parasites and involved in allergies
- Basophils - release histamine during allergic reactions

Question 7: Importance of white blood cells
White blood cells are crucial because they protect our bodies from infections and diseases. They identify and destroy harmful invaders like bacteria, viruses, fungi, and parasites. Without them, even minor infections could become life-threatening.

Final Answer:

1. Three major components of blood:
a. Red blood cells
b. White blood cells
c. Plasma

2. Coagulation (or blood clotting)

3. Plasma

4. Hemophilia

5. Plasma

6. Five types of white blood cells:
a. Neutrophils
b. Lymphocytes
c. Monocytes
d. Eosinophils
e. Basophils

7. White blood cells are important because they protect our bodies from infections and diseases by identifying and destroying harmful organisms like bacteria, viruses, and other pathogens.
