Which statement is true for WBC?
Correct answer: D. Can squeeze through blood capillaries
- A. Non-nucleated
- B. In deficiency, cancer is caused
- C. Manufactured in thymus
- D. Can squeeze through blood capillaries
Explanation
The correct answer is that WBCs can squeeze through blood capillaries. This is due to their amoeboid shape and the process known as diapedesis. This ability allows them to move to areas of the body where they are needed, such as sites of infection or injury. The other options are incorrect: WBCs are nucleated, so 'non-nucleated' is false. While a deficiency in WBCs can weaken the immune system, it does not directly cause cancer; instead, an overproduction of WBCs is associated with leukemia, a type of cancer. Lastly, while some WBCs mature in the thymus, they are primarily produced in the bone marrow.

About Blood Vessels
Blood vessels include arteries, arterioles, capillaries, venules and veins, whose wall thickness, elasticity, lumen size and valves suit their roles in circulation. Questions compare pressure and blood flow in each vessel and distinguish pulmonary vessels, which carry blood to and from the lungs, from systemic vessels.
