Using physical measurements, theoretical models and numerical simulations, researchers have shown how the growth of the arteries directly controls that of the veins through a process that depends ...

A team has developed a new tool that images blood flow through capillaries, detecting subtle changes in capillary organization for early diagnosis of disease. More than 40 billion capillaries -- tiny, ...

More than 40 billion capillaries -- tiny, hair-like blood vessels -- are tasked with carrying oxygen and nutrients to the far reaches of the human body. But despite their sheer number and monumental ...

The human circulatory system represents an intricate network of vessels that extends throughout the entire body. This complex arrangement of arteries, veins, and capillaries works continuously to ...

Arteries and veins are blood vessels that are responsible for transporting blood throughout the body. Blood vessels are made up of three layers: tunica intima, media, and adventitia. The tunica intima ...
