Earthworms have blood and it is enclosed in a network of tubes much like the blood system of mammals. It is red because it contains the oxygen carrying pigment hemoglobin. Unlike mammals, where the hemoglobin is inside red blood cells, earthworm hemoglobin is just mixed in the liquid of the blood, commonly called hemolymph. Earthworms pump their blood around the body with the help of 5 specialized blood vessels that contract and expand. They are the worm's hearts.
Your blood is bright red in the artery and dark red in veins. You do not have [ blue blood ] . It only appears blue because the veins which are white are are carrying dark red blood and being viewed through the skin which difuses the light and makes them appear blue. that is partly true but I have herd from all my teachers that your blood is blue in the arteries. Which when you get cut the air puts oxygen in the blood stream that makes the blood turn red. answer #2 The statement that blood is blue inside the body and turns red when in contact with blood makes little sense. How can this be so when blood itself is used to transport oxygen throughout the body? It is not possible for blood to be blue inside the body as well as carry out one of it's main functions. Answer#3 Actually blood is red in the arteries and blue in the vein. Blood in the artery has already combined with oxygen whereas blood in the vein has yet to receive oxygen. So in fact there is both red and blue blood. When a vein is cut open it hits oxygen in the air causing it to turn red. Answer#4 The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red. This also means that blood in the body, once it has been oxygenated, is also red, though much more so when it reaches open air. I think it would be a fun experiment to put your hand in a vacuum chamber with a tight seal around your wrist and prick your finger to see the difference in blood color.
Oxygenated blood is the blood remaining after the oxygen intake by the body from the blood. And than oxygenated blood goes to Lungs and heart with enrich with oxygen for the body.
How much oxygen the blood is receiving (also how well the lungs are functioning) and carrying from the heart to the body's systems.
It is not the blood but the veins that "look" blue, and even then it is not the actual color of the vessel. The difference is in the way colored light moves through the tissues, and how the eye perceives those colors of light.The oxidation state of the iron in the hemoglobin determines it's color; when the blood is oxygenated, the iron's oxidation state changes, changing the color of the blood from dark red to light red. It is never blue.The changes in blood coloration relate to the respiratory pigment, hemoglobin. Hemoglobin is a topologically complex molecule that very readily binds to oxygen. Once the molecule is fully saturated, it reflects in the crimson red spectrum, and therefore fully oxygenated blood appears to be bright red.After the hemoglobin molecule gives up its oxygen to tissue that needs it, the molecule becomes much less reflective, and thus deoxygenated blood appears very dark red to purple. But blue is used in charts and diagrams to contrast against red, red being the arterial system bearing O2 and blue being the "deoxygenated" blood in the venous system.Human blood is always red. It can have different hues of red, but it is still red.
Each hemoglobin molecule can bind to up to four molecules of oxygen. In red blood cells, hemoglobin typically transports around 98-99% of the oxygen in the blood.
Hemoglobin is found in the red blood cells.
The maximum amount of oxygen that can be carried in arterial blood is approximately 20.2 mmol/L. This is equivalent to about 98.5% of the oxygen that is dissolved in the plasma. The remaining 1.5% is bound to hemoglobin and is termed oxyhemoglobin. The amount of oxygen that can be carried by the blood is dependent on the concentration of hemoglobin in the blood as well as the oxygen saturation of hemoglobin. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment which is why the amount of oxygen that can be carried varies in different environments. The following factors affect the amount of oxygen that can be carried in arterial blood: Hemoglobin concentration Oxygen saturation of hemoglobin Partial pressure of oxygen in the environmentHemoglobin is a protein in red blood cells that binds to oxygen and carries it throughout the body. The concentration of hemoglobin in the blood is an important factor in determining how much oxygen can be carried. The oxygen saturation of hemoglobin is determined by the partial pressure of oxygen in the environment. This means that the amount of oxygen that can be carried in the blood varies in different environments. For example in a high-altitude environment where the partial pressure of oxygen is lower the oxygen saturation of hemoglobin is also lower resulting in less oxygen being carried in the blood.
The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red.Source(s):http://www.newton.dep.anl.gov/askasci/bi…
Carboxyhemoglobin is a compound formed in the blood when carbon monoxide (CO) binds to hemoglobin, preventing oxygen from binding. This reduces the blood's ability to transport oxygen to tissues and can lead to carbon monoxide poisoning, as CO has a much higher affinity for hemoglobin than oxygen.
Blood is red due to the presence of hemoglobin, a protein in red blood cells that binds to oxygen. When hemoglobin binds to oxygen, it becomes bright red. Deoxygenated blood appears darker due to the lack of oxygen-bound hemoglobin.
Hemoglobin is a protein in red blood cells that carry oxygen, the test shows how much hemoglobin you have in your blood. Hemoglobin is found by blood being drawn by the vein usually from the inside of the elbow, the health care provider wraps an elastic band around the arm to apply pressure and make the vein swell with blood. Then the health care provider inserts a needle in the vein.
It makes the red blood cell much better at carrying oxygen!! It can absob oxygen easily and doesn't "leak" oxygen as the blood travels to the body tissues where the oxygen is needed!
The chemical in red blood cells that binds to oxygen is called hemoglobin. Hemoglobin contains iron, which is essential for transporting oxygen from the lungs to the body tissues and carrying carbon dioxide back to the lungs for exhalation.
Carbon monoxide binds to hemoglobin in red blood cells with much greater affinity than oxygen, forming carboxyhemoglobin. This reduces the amount of hemoglobin available to bind with oxygen, leading to decreased oxygen saturation in the blood. This can result in tissue hypoxia and potentially lead to serious health effects.
It is dark red. The oxygen attaches to the iron in hemoglobin, turning it a much brighter red.
O2 saturation, or oxygen saturation, refers to the percentage of hemoglobin in red blood cells that is carrying oxygen. It is a measure of how well oxygen is being transported throughout the body. Normal levels typically range from 95-100%.
