The heart operates as a pump, delivering oxygenated blood through arteries and collecting deoxygenated blood through veins. This double circulation system includes exceptions like the pulmonary artery and vein, responsible for blood purification in the lungs.
Differences between arterial and venous blood are crucial for
medical professionals. Arterial blood, oxygen-rich, flows away from the heart,
driven by its pumping action. Venous blood, deoxygenated, flows toward the
heart, facilitated by muscle contractions in veins.

Venous and Arterial blood differ?
Blood pressure, partial pressure of oxygen, color,
constitution, pH value, and temperature distinguish the two types. Arterial
blood, bright-red, carries oxygen, vitamins, minerals, and glucose. Venous
blood, dark-red, is rich in metabolic wastes.
Arterial blood, with a pH of 7.4, is used for arterial blood
gases, indicating lung function. Venous blood, routinely drawn for tests,
provides reference ranges in reports.
Extraction methods differ; arterial blood is obtained directly
from arteries, often the radial artery, while venous blood is drawn from veins
in the arm or hand. Understanding these distinctions aids in diagnostics and
medical treatments.
