What is the primary issue in leukemia?

Underproduction of white blood cells
Overproduction of platelets
Overproduction of red blood cells
Overproduction of abnormal white blood cells (correct)

Why are the abnormal white cells unable to protect the body against disease?

They are not trained to fight diseases
They are too small to be effective
They lack proper nutrients
They are defective (correct)

What is the impact of the abnormal white cells crowding the bone marrow?

Improvement in immune response
Increased production of red blood cells
Enhanced oxygen transport
Obstruction of blood flow (correct)

What is the core issue in leukemia?

Overproduction of abnormal white blood cells, resulting in a shortage of healthy blood cells.

Why are abnormal white blood cells ineffective?

Abnormal white blood cells in leukemia are defective and unable to function properly, making them ineffective in protecting the body against infections.

What is the impact of abnormal white blood cells crowding the bone marrow?

The abnormal white blood cells in leukemia crowd the bone marrow, blocking the production of healthy blood cells and hindering blood flow.

What is the role of the bone marrow in blood cell production?

The bone marrow is responsible for producing all three types of blood cells: red blood cells (carry oxygen), white blood cells (fight infection), and platelets (help blood clot).
