Where do most deep venous thrombi originate?

Question

Quizplus · Accepted Answer

The lower extremities and pelvic region are the most common sites of origin for deep venous thrombi. This is due to factors such as reduced blood flow in the veins, damage to the veins, and the effects of gravity on blood flow. Deep venous thrombi can also originate in other areas of the body such as the upper extremities or the heart, but these are less common. Below the knees is also a possible site of origin for deep venous thrombi, but not the most common.
