Q1. List and describe the 3 functions of blood.

Background

Topic: Functions of Blood

This question tests your understanding of the major roles blood plays in the human body, which is foundational for understanding the circulatory system in Anatomy & Physiology.

Key Terms:

• Transport

• Regulation

• Protection

Step-by-Step Guidance

1. Think about what substances blood moves throughout the body (e.g., gases, nutrients, wastes).

2. Consider how blood helps maintain homeostasis (e.g., temperature, pH, fluid balance).

3. Reflect on how blood helps defend the body against threats (e.g., pathogens, blood loss).

Q7. Where do all formed elements originate?

Background

Topic: Hematopoiesis

This question tests your knowledge of the origin of blood cells.

Key Terms:

• Hematopoietic stem cell

• Red bone marrow

Step-by-Step Guidance

1. Recall the process by which blood cells are formed.

2. Identify the specific stem cell responsible for giving rise to all formed elements.

Q8. Which are complete cells and which are incomplete (missing something)?

Background

Topic: Blood Cell Structure

This question asks you to distinguish between the different formed elements based on their cellular completeness.

Key Terms:

• Erythrocytes

• Leukocytes

• Platelets

Step-by-Step Guidance

1. Recall which blood cells have a nucleus and organelles.

2. Identify which formed elements are considered "complete" cells and which are not.
