Oxygen Transport Pathophysiology Quiz

What is the primary function of erythropoietin?

How are reticulocytes used as a diagnostic tool?

What is the primary method of O2 transport in the blood?

What is the main function of bilirubin in the body?

What causes the shift of the oxygen-hemoglobin dissociation curve to the right?

What is the primary site of red blood cell (RBC) production in adults?

What is the structure of hemoglobin (Hb) in adults?

How does fetal hemoglobin (HbF) differ from adult hemoglobin (HbA)?

What is the primary method of carbon dioxide (CO2) transport in the blood?

What is the main cause of jaundice in newborns?

Erythropoietin

Primary function: Stimulates the production of red blood cells in the bone marrow

Reticulocytes

Used as a diagnostic tool to evaluate the bone marrow's response to anemia
High reticulocyte count indicates an adequate response to anemia

Oxygen Transport

Primary method of O2 transport in the blood: Bound to hemoglobin (Hb) in red blood cells
Hemoglobin binds to oxygen in the lungs and releases it in the tissues

Bilirubin

Main function: Breakdown product of hemoglobin, removed from the body through the liver and excreted into bile

Oxygen-Hemoglobin Dissociation Curve

Shift to the right caused by: Increased temperature, increased CO2, and decreased pH
Shift to the right increases oxygen delivery to tissues

Red Blood Cell Production

Primary site of RBC production in adults: Bone marrow

Hemoglobin Structure

Structure of hemoglobin (Hb) in adults: Tetramer composed of two alpha and two beta subunits

Fetal Hemoglobin

Fetal hemoglobin (HbF) differs from adult hemoglobin (HbA) in: Higher affinity for oxygen, allowing for more efficient oxygen delivery to the fetus
HbF has a higher affinity for oxygen due to a higher affinity for 2,3-bisphosphoglycerate (2,3-BPG)

Carbon Dioxide Transport

Primary method of CO2 transport in the blood: Carried as bicarbonate ions in the plasma

Jaundice in Newborns

Main cause of jaundice in newborns: Physiological jaundice, a normal response to the breakdown of fetal hemoglobin after birth
