Veins‚ in contrast‚ are subjected to much lower pressures and have thinner walls overall‚ with the tunica adventitia often outsizing the tunica media. Because thinwalled veins conduct blood back to the heart against gravity‚ valves (not present in arteries) also are present at intervals to

HARVEY Jamee’ Hall Charter College Abstract William Harvey (1578-1657) had refused prior explanations of blood circulation and motion. He studied by observing the direction of the valves in the veins. He noted the comparisons between to the cardiac valves‚ and investigated the many valves in the veins‚ recording the discrepancy of prior beliefs. Harvey considered a substitute hypothesis that the blood circulates. His fascination and studies led to the discovery of blood circulation. He revealed

It can be potentially dangerous if a clot breaks off and travels through the blood stream‚ through the heart into the pulmonary arteries causing a small pulmonary embolism; consequently a large embolism can be fatal. Therefore‚ in order to assist with avoiding the blot clots forming and potentially breaking off‚ Lovenox is given either under the skin or through a vein in an iv. Loenox
