What is the primary function of red blood cells?

• Transporting oxygen and carbon dioxide

• Producing hormones

• Fighting infections

• Regulating body temperature

How do white blood cells contribute to the immune system?

• White blood cells identify and attack pathogens, contributing to the immune response.

• White blood cells help in the digestion of food particles.

• White blood cells are primarily responsible for oxygen transport in the blood.

• White blood cells produce hormones that regulate metabolism.

What role do platelets play in the blood?

• Platelets are responsible for nutrient absorption.

• Platelets regulate blood pressure.

• Platelets help in blood clotting and stopping bleeding.

• Platelets transport oxygen to tissues.

Which blood component is responsible for transporting oxygen?

• Platelets

• Red blood cells

• Plasma

• White blood cells

What is the significance of plasma in the circulatory system?

• Plasma has no role in immune response.

• Plasma is significant for transporting nutrients, hormones, and waste, maintaining blood pressure, and supporting immune functions.

• Plasma is primarily responsible for oxygen transport.

• Plasma is the main component of red blood cells.

Describe the process of blood typing using the ABO system.

• The process of blood typing using the ABO system involves mixing blood with anti-A and anti-B antibodies to identify the presence of A and B antigens.

• Performing a DNA test to identify blood type.

• Using a microscope to examine blood cells for color changes.

• Mixing blood with saline solution to determine blood type.

What are the possible blood types in the ABO system?

• A1, B1, AB1, O1

• A, B, AB, O

• X, Y, Z, W

• A+, B+, AB+, O+

How can agglutination be used to determine blood type?

• Agglutination is used to measure blood pressure.

• Agglutination can determine blood type by mixing blood with water.

• Agglutination identifies blood type by observing color changes in the blood.

• Agglutination can determine blood type by mixing blood with specific antibodies and observing for clumping.

What is the importance of knowing a person's blood type before a transfusion?

• It helps in determining a person's age.

• It allows for faster blood donation processes.

• It prevents adverse reactions and ensures compatibility.

• It is necessary for diagnosing diseases.
