Blood Circulation Fundamentals

Blood Circulation Fundamentals

Blood Circulation Fundamentals The heart propels oxygenated arterial blood from the left chambers through arteries, with deoxygenated venous blood returning via veins to the right chambers.

Key Contrasts ✅ Flow Direction: Arterial away, venous towards the heart. ✅ Driving Forces: Heart pumping for arteries, muscle contractions for veins. ✅ Pressure: Measured in arteries (120/80 mm Hg), rarely in veins.

Oxygen Levels and Colors ✅ Oxygen Levels: Arterial rich (100 mm Hg), venous lower (30-40 mm Hg). ✅ Blood Color: Bright red (arterial) vs. dark red (venous).

Medical Insights ✅ Extraction Methods: Arterial via radial artery, venous through arm or hand veins. ✅ Testing Focus: Arterial for oxygen evaluation, venous for routine tests.
