The brain relies on real-time delivery of oxygen and nutrients through its microvasculature, which threads through neural ...

How do blood vessels stay strong, flexible, and responsive to the body's changing need for oxygen and nutrients? The answer ...

Cutaneous blood flow and microcirculation underpin critical physiological processes including thermoregulation, nutrient delivery and immune defence. The skin’s vascular network, comprising ...

Scientists have uncovered a new biological mechanism behind tissue and organ damage in low-oxygen conditions like heart attacks, strokes, and severe COVID-19. Bursting red blood cells—not traditional ...

Red blood cells carry oxygen from the lungs around the body. They then carry carbon dioxide from around the body back to the lungs. These cells are an important component of blood. However, a range of ...

Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to 'waves' ...

Cerebral blood delivery depends on mechanisms such as electrical signaling, which propagates through capillary networks to upstream arterioles to deliver blood, and calcium signaling, which fine-tunes ...
