But I liked understanding the nuts and bolts of how things work. So as an undergraduate at Duke University, I knew I wanted to study physics. The Human Genome Project had just come out, and I was ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs ...

Checking your blood pressure at home or a local pharmacy can be an effective way to stay proactive about your heart health. However, when you're not receiving readings in the presence of a doctor, it ...

For people with advanced heart failure, left ventricular assist devices, or LVADs, can be a literal lifesaver. The implantable devices, which improve blood flow throughout the body, are often the ...

For people with advanced heart failure, left ventricular assist devices, or LVADs, can be a literal lifesaver. The implantable devices, which improve blood flow throughout the body, are often the last ...

Microplastics and nanoplastics might interact with the plaque that causes heart attacks and strokes. A new study found high levels of plastic in the arterial plaque of stroke and vision-loss ...

The film presents a detailed fluorographic study of the normal heart using venous catheterization, showcasing physiological data such as pressure and flow measurements. It illustrates blood flow ...

The study’s authors say previous research shows poor blood flow in leg muscles may occur before similar changes in the heart.

Cerebral blood flow (CBF) is vital for delivering oxygen and nutrients to the brain. Many forms of orthostatic intolerance (OI) involve impaired regulation of CBF in the upright posture, which results ...

This ensures the consistent flow of blood in one direction from the heart via arteries (which carry oxygenated blood) and back to the heart via veins (which carry deoxygenated blood along with carbon ...
