A
Small and red, rich in haemoglobin, carry oxygenated blood to tissues of the body
red blood cells
The primary functions of the heart and longs are:Lungs:- Oxygenate the blood- Remove carbon dioxide from the bloodHeart:Circulate blood in the body, so that cells receive oxygenated blood.Circulate blood in the body, so that de-oxygenated blood is once again oxygenated and carbon dioxide removed.
Arterioles.
Blood in the arteries is oxygenated. Blood in the veins is de-oxygenated. With the exception of the pulmonary arteries which carry de-oxygenated blood, and the pulmonary veins that carry oxygenated blood.
Blood distributes oxygen to the cells in the body. This allows the cells to carry out cellular respiration and carry out their processes.
In relation to the human body, it is a common misconception that blood is blue; all blood is red. The blue appearance is due to the connective tissues of the blood vessels. Blood cells can be either erythrocytes, which are red, or leukocytes, which are white. When blood is oxygenated it is a much brighter red than de-oxygenated blood.
The vessels that carry oxygenated blood to all cells in the body are called arteries. Arteries are muscular blood vessels that transport oxygen-rich blood away from the heart to the rest of the body.
Systemic circulation is also regarded as a greater circulation because it sends oxygenated blood to the cells of the body and takes de-oxygenated blood from the cells to the heart, Therefore the cells will live longer.
