Q1. What are the functions of the cardiovascular system?

Background

Topic: Cardiovascular System Overview

This question tests your understanding of the main roles the cardiovascular system plays in the human body, including transport, regulation, and protection.

Key Terms:

  • Transport: Movement of substances like oxygen, nutrients, hormones, and waste.

  • Regulation: Maintenance of homeostasis (e.g., temperature, pH, fluid balance).

  • Protection: Defense against pathogens and blood loss.

Step-by-Step Guidance

  1. Start by listing the three main functions: transport, regulation, and protection.

  2. For each function, think about specific examples (e.g., what substances are transported, how homeostasis is regulated, and how the system protects the body).

  3. Consider how the cardiovascular system interacts with other systems (e.g., immune system, endocrine system).

Try summarizing these functions in your own words before checking the answer!

Final Answer:

The cardiovascular system functions to transport substances (oxygen, nutrients, hormones, waste), regulate homeostasis (temperature, pH, fluid balance), and protect the body (immune response, clotting).

Q2. What is the composition of blood plasma?

Background

Final Answer:

Blood plasma is composed of water, proteins (albumin, globulins, fibrinogen), ions (Na+, K+, Ca2+, Cl-, HCO3-), nutrients, waste products, hormones, and gases.

Q3. What are the functions of white blood cells?

Background

Topic: Leukocyte Function

This question tests your understanding of the roles played by different types of white blood cells in immunity and defense.

Key Terms:

  • White blood cells (leukocytes): Cells involved in immune response.

  3. Note the differences between granular and agranular leukocytes.

Try matching each cell type to its function before checking the answer!

Final Answer:

White blood cells defend against infection, remove debris, and help with immune responses. Each type has specialized functions: neutrophils (phagocytosis), lymphocytes (immunity), monocytes (phagocytosis), eosinophils (parasite defense), basophils (inflammation).

Q4. What is the function of erythrocytes?

Background

Topic: Red Blood Cell Function

This question tests your understanding of how erythrocytes are specialized for their role in oxygen transport.

Key Terms:

  • Erythrocytes: Red blood cells.

  • Hemoglobin: Protein that binds oxygen.

  • Biconcave shape: Increases surface area for gas exchange.

Step-by-Step Guidance

  1. Describe the main function of erythrocytes (oxygen and carbon dioxide transport).

  2. Explain how their structure (biconcave shape, lack of nucleus) supports this function.

  3. Discuss the role of hemoglobin in oxygen binding and release.

Try explaining how structure relates to function before checking the answer!

Final Answer:

Erythrocytes transport oxygen from the lungs to tissues and carbon dioxide back to the lungs. Their biconcave shape and hemoglobin content make them efficient for gas exchange.

Q5. How is the ABO blood typing system set up?

Background

Topic: Blood Typing

This question tests your understanding of antigens and antibodies in the ABO system and compatibility for transfusions.

Key Terms:

  • Antigens: Surface markers on red blood cells (A, B).

  • Antibodies: Proteins in plasma that react with antigens.

  • Type O: No A or B antigens, both anti-A and anti-B antibodies.

Step-by-Step Guidance

  1. Identify which antigens are present on each blood type (A, B, AB, O).

  2. Determine which antibodies are present in the plasma for each type.

  3. Consider compatibility for transfusions based on antigens and antibodies.

Try mapping out the antigen-antibody relationships before checking the answer!

Final Answer:

The ABO system is based on the presence or absence of A and B antigens on red blood cells and corresponding antibodies in plasma. Type O has no antigens and both anti-A and anti-B antibodies.

Q6. What are the 3 processes of blood clotting?

Background

Topic: Hemostasis

This question tests your knowledge of the steps involved in stopping blood loss.

Key Terms:

  • Vasoconstriction: Narrowing of blood vessels.
