Q1. What are the components of blood?

Background

Topic: Blood Composition

This question tests your knowledge of the main components that make up human blood, a key concept in understanding how the circulatory system functions.

Key Terms:

• Plasma: The liquid portion of blood.

• Formed elements: The cellular components, including red blood cells, white blood cells, and platelets.

Step-by-Step Guidance

1. Recall that blood is made up of both a liquid and cellular portion.

2. Identify the name of the liquid portion of blood.

3. List the three main types of cells or formed elements found in blood.

4. Combine your answers to state the two broad categories that make up blood.

Q5. What is the function of lymphocytes (a type of agranulocyte)?

Background

Topic: White Blood Cell Types and Functions

This question tests your understanding of the role of lymphocytes in the immune system.

Key Terms:

• Lymphocyte: A type of agranulocyte (white blood cell).

• Immune response: The body's defense against pathogens.

Step-by-Step Guidance

1. Recall the two main types of lymphocytes (T cells and B cells).

2. Think about the general function of lymphocytes in immunity.

3. Consider how lymphocytes differ from other white blood cells in their response to pathogens.

Q6. What are the three phases of hemostasis?

Background

Topic: Hemostasis (Blood Clotting)

This question tests your knowledge of the steps involved in stopping bleeding after a blood vessel is injured.

Key Terms:

• Hemostasis: The process of stopping bleeding.

• Vascular spasm, platelet plug formation, coagulation: The three phases.

Step-by-Step Guidance

1. Recall what happens immediately after a blood vessel is damaged.

2. Think about the role of platelets in the process.

3. Identify the final phase that leads to the formation of a stable clot.
