For example, instructional visuals of the circulatory system commonly follow conventions such as ‘flipping’ the orientation of left and right sides of the heart, representing the heart’s structures is three dimensions, or using red and blue to represent oxygenated or deoxygenated blood, ...
Reflectance images were collected during periods of green LED light illumination at 530 nm (equally absorbed by oxygenated and deoxygenated hemoglobin, M530L3, Thorlabs) or blue LED light illumination at 470 nm (absorbed more by oxygenated than deoxygenated hemoglobin, M470L3, Thorlabs). For ...
In fact, we observed in a few subjects that changes in tissue oxygenation were considerably weaker than changes in oxygenated and deoxygenated hemoglobin. An additional limitation of this study is the low sample size, which prevented analysis of sex-related differences. Considered the sex-related ...
which delivers blood to the lungs; which then sends fresh, oxygenated blood to the left atrium; at which point it enters the systemic circulation, starting with the left ventricle; which pumps blood to the body; and then deoxygenated blood comes back to the right atrium; and it all starts ...
In a nutshell, veins being blue has nothing to do with the kind of blood (oxygenated/deoxygenated) that they carry; it’s entirely dependent on their location beneath the skin!
For congruent trials, the top row contained the words "RED," "BLUE," "GREEN," or "YELLOW" written in a color congruent with that of the bottom row. For incongruent trials, the color word in the top row was written in an incongruent color to produce interference between the color of ...
activation of the sympathetic nerve fibers close the shunts so that oxygenated blood (red arrows) in the arterioles is forced into the capillaries and deoxygenated (blue arrows) blood returns to the venules. As shown to the right, in order to conserve heat when we are cold, activation of se...
Oxygenated hemoglobin absorbs weakly in the red (hence its red color) and strongly in the near infrared, whereas deoxygenated hemoglobin has the opposite absorption. This fact is used in a "pulse oxim Which of the following hormones acts to lower the b...
mixture of the blood to the rest of the body. This causes the cells of the body to not receive all of the required oxygen that it would normally obtain with a fully intact septum, thus causing the cyanotic, or blue, appearance of the patient. The second most commonly occurring defect is...
Aliphatic C–H region (blue); Area 1: alkanes, Area 2: Ar-Me, Area 3: Allylic/benzylic. Oxygenated aliphatic C–H region (red); Area 1: OMe, Area 2: Ar-OMe, Area 3: ROH, Area 4: RO, Area 5: levoglucosan. Aromatic and unsaturated C–H region (green); Area 1: alkenes, Area...
