Using factors like blood flow and stiffness components to quantify brain health could help lead to earlier detection of neurological diseases like Alzheimer's, which currently has no cure.

These can be associated with arrhythmias (irregular heartbeats), blood clots, and heart failure. The right atrium plays a part in both the flow of blood through the heart and in the heart's electrical ...

The following is a step-by-step explanation of blood flow through the heart. The left and right atrium contract once they are filled with blood. This pushes open the mitral and tricuspid valves. Blood ...

Dr. Matthew Tomey, a cardiologist at Mount Sinai Fuster Heart Hospital in New York City, said the findings support a patient asking for a doctor to measure blood pressure the "right way." ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...

This fist-sized powerhouse beats (expands and contracts) 100,000 times per day, pumping 5 or 6 quarts of blood each minute, or about 2,000 gallons per day. So how does blood flow through the heart?

Scientists rediscovered the red-bellied squeaker frog, a species feared extinct, in Democratic Republic of the Congo. Photos show the first sighting since the 1950s. Photo from Eli Greenbaum A ...
