Arteries are blood vessels. Most carry oxygen-rich blood from the heart to various organs and tissues. Arteries are a part of the circulatory system, along with the heart and other blood vessels. The ...

The endothelium is a cell layer that lines the body’s blood vessels and lymphatic vessels. These cells are necessary to maintain healthy organs, tissues, and overall body function. The cells of the ...

The brain and its surrounding blood vessels exist in a close relationship. Researchers have discovered how cells of the blood vessels sense the metabolic condition of the brain and alter vascular ...

The heart pumps blood through the vascular system, supplying cells with oxygen and energy Smooth muscle cells in the vessels finely regulate the blood flow. If they cannot perform their task, ...

Developing drugs that stop blood vessel growth in cancer — causing tumors to shrink — is a hot area in pharmaceuticals. Still, researchers and clinicians don’t know as much as they would like about ...

Healthy brain function relies on a steady supply of blood. Disruptions in blood flow are linked to major neurological conditions like stroke, Alzheimer's disease (AD), and traumatic brain injuries.

Serious complications due to blood clots, such as heart attacks and strokes, that are experienced by some COVID-19 survivors may be caused by a lingering immune response in the blood vessels after ...

Cambridge scientists have grown small blood vessel-like models in the lab and used them to show how damage to the scaffolding that supports these vessels can cause them to leak, leading to conditions ...

Among other side effects, smoking does cause blood vessels to constrict. This can lead to sometimes life threatening events like heart attack or stroke. Smoking is linked to a wide range of negative ...

Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood ...
