Imagine, for example, that you have an important job interview. You are excited, your heart beats faster and your blood pressure rises so that your muscles and organs get enough oxygen and energy to deal with the stressful situation. After the interview is over, you can breathe again. Your ...
Vitamin B12 (cyanocobalamin) is an oxygen carrier; it decreases blood cholesterol; it metabolizes fat. Vitamin B12 is essential in humans for healthy nerve tissues. Its deficiency is associated with heart palpitations. Diagnose your symptoms now! check your overall health status learn what you shoul...
The circulatory system consists of the heart and the blood vessels of the body. These vessels include arteries, capillaries, and veins. The circulatory system is responsible for ensuring adequate oxygen and nutrients are delivered to the tissues of the body, while also removing their wastes. ...
oxygen levels in order to provide for aerobic life forms. As dissolved oxygen levels in water drop below 5.0 mg/l, aquatic life is put under stress. The lower the concentration, the greater the stress. Oxygen levels that remain below 1-2 mg/l for a few hours can result in large fish ...
A cl ear excess significance bias has been dem- onstrated in studies of brain volume abnormalities73, and similar problems appear to exist in fMRI studies of the blood-oxygen-level-dependent response77. In order to establish the average statistical power of stud- ies of brain volume ...

Regular aerobic exercise lowers fibrinogen levels – a risk factor for atherosclerosis of equal or greater predictive value than cholesterol. Additionally, exercise improves the production of nitric oxide within the blood vessel wall, which should limit the progression of atherosclerosis. Exercise improves...

The HbA1c test takes advantage of a natural—but harmful—consequence of the impact of blood sugar on the body’s proteins—in this case hemoglobin, the carrier of oxygen in our bloodstreams: it literally “cooks” in a low-temperature version of caramelization—the kitchen chemistry process by...
too. That's because when you're parched, your heart has to work harder, according to theCDC. Not getting enough fluids reduces total blood volume, which places demands on your ticker, Dr. Li says; it needs to beat faster and stronger for the same amount of nutrients and oxygen to get...
