Detailed explanation-1: -Arterial blood is the oxygenated blood in the circulatory system found in the pulmonary vein, the left chambers of the heart, and in the arteries. It is bright red in color, while venous blood is dark red in color (but looks purple through the translucent skin).

Detailed explanation-2: -RBCs contain hemoglobin (pronounced: HEE-muh-glow-bin), a protein that carries oxygen. Blood gets its bright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releases oxygen to the different body parts.

Detailed explanation-3: -The oxygenated Blood is moreover called vein blood. Oxygenated Blood contains two kinds of veins conveying Blood all through our bodies: Arteries convey oxygenated Blood (Blood that has gotten oxygen from the lungs) from the heart to the remainder of the body.

Detailed explanation-4: -Blood is always red. Blood that has been oxygenated (mostly flowing through the arteries) is bright red and blood that has lost its oxygen (mostly flowing through the veins) is dark red. Anyone who has donated blood or had their blood drawn by a nurse can attest that deoxygenated blood is dark red and not blue.

Detailed explanation-5: -Blood is red in colour. Oxygen-rich blood is bright red as it leaves the heart. When it returns to veins without oxygen, it turns blue.
