Immune cells that engulf and digest cellular debris and pathogens.

A protein that transports iron (Fe2+) in the bloodstream.

The rupture of red blood cells (RBCs), releasing their contents.

A yellow compound that occurs from the breakdown of hemoglobin, often bound to albumin.

The average lifespan of red blood cells is approximately 120 days.

System consisting of the heart, blood vessels, and blood.

Specialized connective tissue containing cells in a fluid matrix.

Transport, regulation, restriction, defense, and stabilization.

High viscosity, slightly alkaline, with a temperature of 38ºC.

Separation of whole blood into plasma and formed elements.

Fluid component of blood, making up 55% of its volume.

Cells and cell fragments in blood, including RBCs and WBCs.

Proteins in plasma, including albumins that regulate osmolarity.

The processes involved in stopping bleeding, including Vascular, Platelet, Coagulation, and Clot Retraction phases.

The initial response to blood vessel injury characterized by contraction of endothelial cells and vascular spasm to reduce blood flow.

The process where platelets attach to damaged blood vessel surfaces, starting the formation of a platelet plug.

The sticking of activated platelets together to form a temporary plug at the site of a blood vessel injury.

Platelets that, upon injury, release chemicals promoting clotting, aggregation, and vascular repair.

A condition where blood has an increased tendency to form clots.

A blood clot formed in one or more deep veins, usually in the legs.

The process where platelets contract, pulling vessel edges together to stabilize an injury.

The gradual process of dissolving a blood clot after healing occurs.

The process that prevents and stops bleeding, maintaining blood in a fluid state.

A protein that forms a fibrous network to generate blood clots.

A protein that is converted to thrombin during the clotting process.

An enzyme that converts fibrinogen to fibrin and activates platelets in clotting.

Essential ions needed in various stages of blood coagulation.

A vitamin required for synthesizing several clotting factors.

A condition characterized by an abnormally low level of platelets.

An inherited bleeding disorder where blood doesn't clot properly.

One of the pathways leading to coagulation that begins with damage to the vessel.

The pathway that begins with external trauma leading to clotting.

Substances on cell membranes that identify cells to the immune system.

Classification of blood based on surface antigens present on RBCs (A, B, AB, O).

Surface antigens on red blood cells that determine blood type.

Antibodies present in plasma that attack foreign RBC antigens.

A blood type that lacks A and B surface antigens and has both anti-A and anti-B antibodies.

Classification based on presence (Rh+) or absence (Rh-) of the Rh antigen.

A transfusion reaction that occurs if blood types are incompatible.

Type O- blood, which can be given to any blood type without causing reactions.

Type AB+ blood, which can receive any blood type.

Tests conducted prior to transfusions to find compatible blood types.

Condition occurring when an Rh- mother has an Rh+ fetus, leading to immune response in subsequent pregnancies.

A mother with the Rh antigen, typically does not cause issues with pregnancy.

Antibodies produced by Rh- mothers after exposure to Rh+ blood, can affect future pregnancies.
