question 21
septicemia is derived from the greek word septikos, which means:
rotting
gangrenous or green
bloody
poison or putrefying

Explanation:

• For Question 19: A thrombus is a blood - clot formed inside a blood vessel. Infarction is tissue death due to lack of blood supply, atheroma is a fatty deposit in artery walls, and embolism is a foreign body (including a clot) that travels in the blood.
• For Question 20: The sinoatrial node is the heart's natural pacemaker. A defect in it can disrupt the normal electrical impulses, leading to arrhythmia (irregular heartbeat). Cardiomyopathy is a disease of the heart muscle, endocarditis is inflammation of the inner lining of the heart, and myocardial infarction is a heart - attack due to blocked blood supply to the heart muscle.
• For Question 21: The Greek word "septikos" means poison or putrefying, which is related to the condition of septicemia where there is a bacterial infection in the bloodstream causing a toxic state.

Answer:

Question 19: A. thrombus
Question 20: A. arrhythmia
Question 21: D. poison or putrefying
