Blood is red, whether it is oxygenated or de-oxygenated. Oxygenated blood is bright red. De-oxygenated blood is dark red to redish purple. The veins (which carry de-oxygenated blood) appear blue due to an optical effect caused by the way light penetrates the skin. Blood is red because it...
Blood is a thick, red fluid which carries oxygen, water and food to all parts of the body. It keeps the body at the right temperature (温度) and protects it from disease. If you lose a lot of blood, you need new blood. You can receive new blood from other people. This is ...
What’s in Blood? A. Blood is the most specialised fluid within living animals, playing an absolutely critical role. It symbolises life (‘new blood’), health (‘get your blood running’), personality (‘good or bad blood’), and family (‘your bloodline’). This red fluid itself is...
Agglutination is the mechanism where cells start aggregating into clumps. This is generally a cause of blood clots. Due to their increased size, these clots can start clogging up blood vessels, stopping circulation.Answer and Explanation:

can detect. Red objects reflect red wavelengths and absorb other colors. Red pigments get their color from chemicals such as anthocyanin, lycopene, carotene, and astaxanthin. Blood is red due to the iron-containing protein hemoglobin. Rubies contain the mineral chromium which causes the red color....
These transport oxygen molecules throughout the body, and also give blood its colour (from the hemoglobin protein within, which turns red when combined with oxygen). Red blood cells, as with all cells in the human body, have a limited operating life. They are produced within the marrow of ...
