MS-1759

A 50-year-old female presents to the emergency department with leg pain. She has recently returned from Thailand.

On examination of her lower limbs, tender calves are noted.

A Doppler scan of the lower limbs confirms deep vein thrombosis.

The consultant discusses the option of using heparin and briefly outlines the mechanism of action of heparin and its method of distribution in the body for the benefit of the medical resident present.

What is the correct statement regarding the distribution of heparin in the body?
