In the brain, increased neural activity is correlated with increases of cerebral blood flow and tissue oxygenation. However, how cerebral oxygen dynamics are controlled in the behaving animal remains unclear. We investigated to what extent cerebral oxyge
Veins are afferentblood vesselsthat carry blood that is rich in carbon dioxide and low inoxygenback towards the lungs and heart. They are similar in structure to the efferent blood vessels known as arteries, with an outer layer composed of protective tissue, a middle layer made of muscle tissu...
is not blue. In fact, no kind of human blood is blue. If anything, deoxygenated blood is even redder than regular, oxygenated blood. If you have ever had your blood drawn and noticed its color, you would clearly know that deoxygenated blood is a dark red. ...
How does blood become deoxygenated? Describe the transport of CO2 in arterial and venous blood, including the exchange of CO2 between the blood and the alveoli or cells. How do pulmonary capillaries contribute to homeostasis? Does blood transport carbon dioxide and waste to each cell? Describe the...
there is hardly a difference to be observed between the deoxygenated and the oxygenated fingers. However, looking at the hyperspectral curves, there is a clear difference in the hyperspectral response for both fingers, related to the presence of oxygenated versus deoxygenated blood. These results indi...

as well as some molluscs have blue blood. And it all comes down to having a differentrespiratorypigment, called haemocyanin. Haemocyanin has a different atomic structure that contains copper atoms instead of iron atoms. Because of this, the blood is colourless when deoxygenated, and blue, whe...
A capillary bed is a concentration of capillaries that supply blood to a specific part of the body. The density of a capillary bed...
Deoxygenated blood in the veins is actually dark red, but veins close to the surface of the skin often appear blue in color because the skin causes some light refraction to occur. Lymphatic fluid is the term used to describe interstitial fluid, or fluid that exists between cells, after it ...
