Blood Lab Overview

These flashcards cover the key concepts related to the composition of blood, types of blood cells, blood pathologies, and blood typing.

Plasma

Liquid component of blood, making up about 55% of its volume; contains water, salts, nutrients, hormones, and proteins.

Erythrocytes

Red blood cells responsible for transporting oxygen and carbon dioxide in the bloodstream.

Leukocytes

White blood cells involved in the immune response; they help defend the body against infections.

Platelets

Small cell fragments essential for blood clotting.

Hematocrit

Percentage of blood volume occupied by red blood cells.

Anemia

Condition characterized by an abnormally low oxygen-carrying capacity of blood due to insufficient red blood cells or hemoglobin.

Leukocytosis

Increase in white blood cell count, often a response to infection.

Blood Typing

Method to determine blood group based on the presence or absence of specific antigens on red blood cells.

ABO Blood Group

Classification of blood based on the presence or absence of A and B antigens.

Rh Factor

Specific antigen present on red blood cells that determines whether blood type is positive (+) or negative (-).
