It is one of the two parts of the cardiovascular system, where systemic circulation being the other. Cardiovascular system is the blood supply of the entire body, being formed of...
An overview on how blood vessels deliver nutrients to cells
By: Janet Farricelli CPDT-KA
While it is pretty straightforward that humans need food in order to survive, not many people are aware of the fact that deep inside our body's core another form of nutrition takes place. That is the delivery of oxygen rich blood to our tissues, organs...
The importance of capillaries for circulation
By: Perry McCarney
The human cardiovascular (CV) system has three types of blood vessels: arteries, capillaries and veins. Circulation through the CV system goes from the heart through the arteries to the capillaries, on to the veins and back to the heart. The arteries and veins are...
The role of the lungs in pulmonary circulation
By: Perry McCarney
The lungs re-oxygenating our blood is what pulmonary circulation is all about. We have a cardiovascular (heart and blood vessels) system composed of two closed circuits. The pulmonary circuit takes de-oxygenated blood, containing low levels of oxygen and large amounts of carbon dioxide, from the...

An overview on how blood vessels deliver nutrients to cells
By: JRR
The human circulatory system has nearly 60,000 miles of blood vessels. These vessels provide a mode of transport for erythrocytes (red blood cells) leukocytes (white blood cells), platelets and plasma. It is the red blood cells that carry oxygen and nutrients to cells...
