Which term means blockage or closure of a blood vessel?

• A. Sagittal plane
• B. Occlusion
• C. Nystagmus
• D. Splenectomy

Answer: (B)

Occlusion is the term that means blockage or closure of a blood vessel. It describes the stoppage of blood flow in an artery or vein, which can happen from a clot, plaque buildup, or other obstruction. This reduced or halted flow can lead to tissue damage from lack of oxygen, as seen in arterial occlusions causing strokes or heart attacks. The other terms refer to different concepts: a sagittal plane is an anatomical slice that divides the body into left and right parts; nystagmus is an involuntary, rapid eye movement; splenectomy is the surgical removal of the spleen.
