What is the function of erythrocytes?

(select all that apply)

• transport oxygen

• transport carbon dioxide

• fight infection

• initiate blood clotting

What is the function of leukocytes?

• transport oxygen

• transport carbon dioxide

• fight infection

• initiate blood clotting

What is the function of platelets?

(select all that apply)

• clump at the site of blood vessel injury

• initiate blood clotting response

• transport carbon dioxide

• fight infection

What is the function of plasma proteins?

(select all that apply)

• transport "vehicle" for certain molecules in the blood (i.e. cholesterol)

• contribute to blood viscosity

• contribute to osmotic pressure of blood

• attack parasites

Which statement(s) are correct for hemoglobin?

• made of 4 protein strands

• excellent transporter of carbon dioxide

• it's "heme" group contains iron and provides the red appearance

• is well-suited to oxygen transportation

Which statement best describes oxyhemoglobin?

• bright red; not carrying oxygen

• dark red-purple; not carrying oxygen

• dark red-purple; bonded to oxygen

• bright red; bonded to oxygen

What symptom(s) are associated with inflammation?

• tissue is hot

• tissue is red

• tissue is painful

• tissue is swollen

What occurs in the inflammatory response?

• injury causes capillaries to dilate; fluid & leukocytes enter tissue

• injury causes capillaries to constrict; tissue is drained of fluid

• injury causes capillaries to dilate; tissue is drained of fluid

• injury causes capillaries to constrict; fluid & leukocytes enter tissue

What occurs in blood clotting?

• injury to blood vessel -- platelets plug the hole, independently forming a blood clot

• injury to blood vessel -- fibrin initiates activation sequence -- platelets then move to site of injury & clump to create blood clot

• injury to blood vessel -- platelets clump & initiate activation sequence -- fibrin strands form a net at site of injury -- clot forms

• injury to blood vessel -- fibrin immediately and independently forms a blood clot

What does the ABO blood-typing system do?

• identifies the presence / absence of Rh protein on red blood cells

• identifies the presence / absence of Rh protein on white blood cells

• identifies the presence / absence of A and B protein on white blood cells

• identifies the presence / absence of A and B protein on red blood cells
