Blood Composition and Terminology Quiz

White Blood Cell Count

• A white blood cell (WBC) count above 10,000 often indicates an infection, inflammation, or other stressors affecting the body.
• A WBC count below 4,000 can be associated with conditions such as leukopenia, which may result from bone marrow disorders or certain infections.

Thrombocytes

• Thrombocytes are also known as platelets, essential for blood clotting and wound healing.

Rh Blood Type

• Rh status, whether positive (Rh+) or negative (Rh-), is determined by the presence or absence of the Rh factor, a specific protein on red blood cells.

Population Statistics

• Approximately 85% of the population is Rh positive, meaning they have the Rh factor.

Erythrocytes Functions

• The primary function of erythrocytes, or red blood cells, is to transport oxygen from the lungs to the body’s tissues and carry carbon dioxide back to the lungs for exhalation.

Leukocytes Functions

• Leukocytes, or white blood cells, play a critical role in the immune system by defending against infections, pathogens, and foreign invaders.

Blood Color

• Hemoglobin, a protein found in red blood cells, is responsible for giving blood its red color, particularly when oxygenated.

Plasma Functions

• Plasma acts as the liquid component of blood, facilitating the transportation of cells, nutrients, hormones, and waste products throughout the body.

Antibody Production

• B cells, a type of leukocyte, are responsible for producing antibodies and removing dead or damaged cells, key elements in the body’s immune response.
