Question

What is sickle cell anemia and how does it affect the perfusion of oxygen in the blood?

a) Sickle cell anemia is a disorder of white blood cells affecting oxygen transport efficiency.
b) Sickle cell anemia is a genetic disorder of red blood cells, causing them to become rigid and affecting oxygen perfusion.
c) Sickle cell anemia is a condition leading to an overproduction of platelets, decreasing oxygen perfusion.
d) Sickle cell anemia is a disorder of plasma proteins, affecting oxygen transport in the bloodstream.

Answer 1

Sickle cell anemia is a genetic disorder where red blood cells become sickle-shaped due to abnormal hemoglobin, causing poor oxygen delivery and various health complications.

Step-by-step explanation:

Sickle Cell Anemia and Perfusion of Oxygen

Sickle cell anemia is a genetic disorder that affects the shape and function of red blood cells. Patients with sickle cell anemia have red blood cells that assume a sickle or crescent shape due to the production of an abnormal type of hemoglobin, known as hemoglobin S. This abnormal shape causes the cells to become rigid and clog the blood vessels, significantly reducing oxygen perfusion into the blood. The impaired flow of these malfunctioning cells through capillaries leads to complications such as severe pain, tissue damage, and an array of other serious health issues. This condition is particularly prevalent among individuals of African descent.

Therefore, the correct answer is: b) Sickle cell anemia is a genetic disorder of red blood cells, causing them to become rigid and affecting oxygen perfusion.
