Venous Blood Venous blood is deoxygenated blood that flows from tiny capillary blood vessels within the tissues into progressively larger veins to the right side of the heart.
Venous blood is the specimen of choice for most routine laboratory tests. The blood is obtained by direct puncture to a vein, most often located in the antecubital area of the arm or the back top of the hand. At times, venous blood may be obtained using a vascular access device VAD such as a central venous pressure line or an IV start.
Most laboratory reference ranges for blood analytes are based on venous blood. Arterial Blood Deoxygenated blood is pumped from the right side of the heart to the lungs where it takes up oxygen. The now oxygenated blood is pumped through the left side of the heart via arteries. The most common reason for collection of arterial blood is the evaluation of arterial blood gases. Venous Blood: The driving force of the venous blood is the muscular contractions. Venous Blood: The normal pressure of the venous blood is mm Hg at the atrium.
Arterial Blood: The arterial blood is bright red in color. Venous Blood: The venous blood is blackish red in color. Arterial Blood: The arterial blood is rich in oxygen and nutrients such as glucose, amino acids, and vitamins. Arterial Blood: The pH of the arterial blood is 7. Venous Blood: The venous blood consists of a lower pH than the arterial blood.
Venous Blood: The temperature of the venous blood is lower than that of the venous blood. Arterial Blood: The arterial blood is collected by the direct puncture of an artery. Venous Blood: The venous blood is collected by the direct puncture of a vein by a venipuncture. Arterial Blood: The Arterial blood is used to test arterial blood gases.
Venous Blood: The venous blood is used for routine blood tests. Arterial blood and venous blood are two types of blood found in the blood vessels of a closed circulation system. Arterial blood is rich in oxygen and nutrients. But, venous blood is rich in metabolic wastes such as carbon dioxide and urea. Since arterial blood is rich in oxygen, the color of the blood is bright red. The color of the deoxygenated venous blood is blackish red. The main difference between arterial and venous blood is the amounts of oxygen dissolved in each type of blood.
