✨✨✨✨✨✨Difference Between Oxygenated and Deoxygenated Blood✨✨✨✨✨


✔Definition
☸Oxygenated Blood: Oxygenated blood refers to the blood that has been exposed to oxygen in the lungs.

☸Deoxygenated Blood: Deoxygenated blood refers to the blood that has a low oxygen saturation relative to blood leaving the lungs.

✔Alternative Names
☸Oxygenated Blood: The oxygenated blood is also called arterial blood.

☸Deoxygenated Blood: The deoxygenated blood is also called venous blood.

✔Oxygen Concentration
☸Oxygenated Blood: The oxygen concentration of oxygenated blood is high.

☸Deoxygenated Blood: The oxygen concentration of deoxygenated blood is low.

✔Carbon Dioxide Concentration
☸Oxygenated Blood: The carbon dioxide concentration of oxygenated blood is low.

☸Deoxygenated Blood: The carbon dioxide concentration of deoxygenated blood is high.

✔Blood Color
☸Oxygenated Blood: The oxygenated blood is bright red in color.

☸Deoxygenated Blood: The deoxygenated blood is blackish red in color.

✔Blood Flow
☸Oxygenated Blood: The oxygenated blood flows from the lungs through the left chambers of the heart to the metabolizing tissues of the body.

☸Deoxygenated Blood: The deoxygenated blood flows from the metabolizing tissues of the body through the right chambers of the heart to the lungs.

✔Direction of the Blood
☸Oxygenated Blood: Oxygenated blood flows away from the heart.

☸Deoxygenated Blood: Deoxygenated blood flows towards the heart.

✔Blood Vessels
☸Oxygenated Blood: Oxygenated blood flows through the pulmonary vein and systemic arteries.

☸Deoxygenated Blood: Deoxygenated blood flows through the pulmonary artery and systemic vein.

✔Driving Force
☸Oxygenated Blood: The driving force of the oxygenated blood is the pumping pressure of the heart.

☸Deoxygenated Blood: The driving force of the deoxygenated blood is the muscular contractions.

✔Blood Pressure
☸Oxygenated Blood: The regular pressure of the oxygenated blood is 120/80 mm Hg.

☸Deoxygenated Blood: The regular pressure of the deoxygenated blood is 5-8 mm Hg at the atrium.

✔Content
☸Oxygenated Blood: The oxygenated blood is rich in oxygen and nutrients such as glucose, amino acids, and vitamins.

☸Deoxygenated Blood: The deoxygenated blood is rich in HCO3 and metabolic wastes such as urea.

✔Blood pH
☸Oxygenated Blood: The pH of the oxygenated blood is 7.40.

☸Deoxygenated Blood: The deoxygenated blood has a lower pH than the oxygenated blood.

✔Temperature
☸Oxygenated Blood: The temperature of the oxygenated blood is 37 ºC.

☸Deoxygenated Blood: The temperature of the deoxygenated blood is lower than that of the venous blood.

✔Role
☸Oxygenated Blood: The main function of oxygenated blood is to supply oxygen to the metabolizing tissues.

☸Deoxygenated Blood: The main function of deoxygenated blood is to carry carbon dioxide to the lungs.

Answer 2

Human blood is red in color, ranging from bright red when oxygenated to a very dark, almost blackish-red when deoxygenated. It owes its color to haemoglobin, to which oxygen binds. Deoxygenated blood is darker due to the difference in color between deoxyhaemoglobin and oxyhaemoglobin.
