Human Physiology Practical

How is the ABO blood grouping system determined in a laboratory setting, and what are its clinical implications?

• By analyzing DNA

• By measuring blood viscosity

• By examining the presence of specific antigens

• By counting platelets

When performing a blood grouping test, the presence of which specific antigens is determined?

• Hemoglobin and bilirubin

• A and B antigens

• Plasma and serum

• Erythrocytes and leukocytes

When performing a blood grouping test, the presence of which specific antigens is determined?

• Hemoglobin and bilirubin

• A and B antigens

• Plasma and serum

• Erythrocytes and leukocytes

What is the function of hemoglobin in the blood?

• Hemoglobin produces red blood cells.

• Hemoglobin carries oxygen and carbon dioxide in the blood.

• Hemoglobin regulates blood pressure.

• Hemoglobin helps in blood clotting.

How does blood type affect blood transfusions?

• Blood type affects blood transfusions by determining compatibility between the donor and recipient.

• Blood type only affects the color of the blood during transfusions.

• Blood type has no effect on blood transfusions.

• Blood type determines the amount of blood that can be transfused.

What is the function of platelets in the blood?

• Regulating blood pressure

• Blood clotting

• Producing antibodies

• Transporting oxygen

What is the process of blood clotting called?

• agglutination

• hemolysis

• thrombosis

• coagulation

Normal value of clotting time is

• 2-5 minutes

• 7-10 minutes

• 15 minutes

• 10-15 minutes

which levels of BP indicates prehypertension?

• systolic: less than 120 mmHg
  diastolic: less than 80mmHg

• systolic: 140 mmHg or higher

  diastolic: 90 mmHg or higher

• systolic: 120–139 mmHg diastolic: 80–89 mmHg

• systolic: 120 mmHg diastolic: 80 mmHg

Why you need to assess bleeding time?

• to know the platelets function

• to know the coagulation time

• to know the immune functions of the blood

• to know the functions of WBS
