pulmonary arterial blood as it has moce CO2 than venous
Venous blood enters the ventricle. The lung oxygenates blood from the aorta.
Arterial blood typically contains more oxygen than venous blood. Arterial blood is oxygen-rich because it comes directly from the lungs after picking up oxygen, while venous blood has delivered its oxygen to the tissues and is returning to the heart to pick up more.
Venous blood travels from the body to the heart in veins and it goes to the right atrium.
Venous blood is preferred for testing because it provides a more accurate representation of the body's overall health compared to capillary blood. Venous blood contains a higher concentration of important substances like glucose, oxygen, and hormones, making it more reliable for diagnostic purposes. Additionally, venous blood is easier to collect in larger quantities, which is often necessary for a wide range of laboratory tests.
our total blood volume is unevenly distributed amongst the arteries, veins and capillaries. The heart, arteries , pulmonary and systemic circuits contain about 1.5 liters of whole blood. The venous system contains 3.5 liters, which is circulating within the liveer, bone marrow and skin.
Depending on body size (body surface area) and state of health, the human venous system contains approximately 67-72 percent of the entire blood volume.
Venous blood is typically used in tests because it provides a more accurate representation of the body's overall blood composition, as it is collected directly from a vein which is closer to the heart. It also contains higher concentrations of substances being measured compared to capillary blood obtained from a fingerstick. Additionally, venous blood is easier to collect in larger volumes needed for multiple tests.
The influx of carbon dioxide in venous blood.
Venous blood is the blood that circulates through the veins, carrying deoxygenated blood back to the heart from the body's tissues. It typically contains higher levels of carbon dioxide and lower levels of oxygen compared to arterial blood, which is oxygen-rich and flows away from the heart. The color of venous blood is usually darker red due to its lower oxygen content. In some cases, venous blood can also be used for diagnostic testing in medical settings.
Venous blood is loaded with carbon dioxide and low in oxygen Arterial blood is rich in oxygen with little carbon dioxide
The vessel that contains blood with the greatest concentration of reduced hemoglobin is the venous blood, specifically in the systemic veins. This is because venous blood has delivered its oxygen to the tissues, resulting in a higher proportion of deoxygenated (reduced) hemoglobin compared to arterial blood, which is rich in oxygen. As blood returns to the heart and lungs through the veins, it carries more reduced hemoglobin due to the oxygen being released to the tissues.
