what do red blood cells deliver to the body?

Answer 1

Yeah Oxygen they have no nucleus so there more space for O2 thay also contain hymoglobin which has something to do with the blood system
BEST ANSWER please i need it

Answer 2

Oxygen. You breathe in and out, so the lungs have a continual supply of oxygen. What happens is depleted cells come through the superior or inferior vena cava in to the right atrium, into the right ventrical, into the pulmonic artery (the only artery with depleted blood), then into the capillaries in the lungs. Once there the cells pick up oxygen and go into the pulmonic vein (the only vein with oxygen rich blood), then the blood travels into the left atrium, then the left ventricle, and finally through the aorta to the rest of the body where they deliver oxygen to parts of the body like muscles, the brain, and nearly all other areas.

Answer 3

Respiration is their key function. In your lungs each red blood cell picks up oxygen, just as a truck might load up at a warehouse. A red cell contains an iron-rich protein called hemoglobin that oxidizes or “rusts,” as it were, in your lungs, that is, it unites with oxygen, becoming bright red. Then comes a quick trip to deliver this to the customers, your body cells. From your lungs the blood speeds to your heart, where it gets a strong push, carrying it through progressively smaller arteries until it reaches the minute capillaries throughout your body. As each red cell passes single-file through a capillary, it quickly delivers up its cargo of oxygen and makes a pickup for the return trip. Your body cells then “burn” oxygen and nutrients to produce energy for you so you can move, think and keep warm. So in the brief passage through your capillaries the blood delivers oxygen and collects the by-product carbon dioxide, which is brought back to your lungs for discharging.

Answer 4

Red Blood Cells deliver Oxygen to the bodies' cells.

Red Blood Cells contain mostly hemoglobin which is largely iron. When you expose iron to oxygen it oxidizes (rusts). This is how red blood cells carry oxygen to the bodies' cells. Of course each cell has to work to pull the oxygen out of the red blood cell.


According to Wikipedia: http://en.wikipedia.org/wiki/Red_Blood_Cells
"Red blood cells are also known as RBCs, haematids or erythrocytes (from Greek erythros for "red" and kytos for "hollow", with cyte nowadays translated as "cell"). RBCs are considered a prokaryotic cell because it does not contain a nucleus.

Erythrocytes consist mainly of hemoglobin, a complex molecule containing heme groups whose iron atoms temporarily link to oxygen molecules in the lungs or gills and release them throughout the body. Oxygen can easily diffuse through the red blood cell's cell membrane. Hemoglobin also carries some of the waste product carbon dioxide back from the tissues. (In humans, less than 2% of the total oxygen, and most of the carbon dioxide, is held in solution in the blood plasma). A related compound, myoglobin, acts to store oxygen in muscle cells.

The color of erythrocytes is due to the heme group of hemoglobin. The blood plasma alone is straw-colored, but the red blood cells change color depending on the state of the hemoglobin: when combined with oxygen the resulting oxyhemoglobin is scarlet, and when oxygen has been released the resulting deoxyhemoglobin is darker, appearing bluish through the vessel wall and skin. Pulse oximetry takes advantage of this color change to directly measure the arterial blood oxygen saturation using colorimetric techniques.

The sequestration of oxygen carrying proteins inside cells (rather than having them dissolved in body fluid) was an important step in the evolution of vertebrates; it allows for less viscous blood and higher concentrations of oxygen."

Answer 5

they deliver the oxygen obtained by the herat. they travel in the veins, the vessels bring the cells back to the heart to pick up more oxygen to take to the rest of the body

Answer 6

They deliver oxygen to all parts of the body.

Answer 7

Red blood cells deliver oxygen from the lungs to rest of the body and carbon dioxide as bicarbonate ions from rest of body to lungs to be expired. It delivers digested food substancees from intestines to all parts of the body. It delivers excretory producis from the tissues to respective excretory organs for removal. Hoemones from the glands which produce them to parts of the body which requires them.
heat produced in respiring body tissues, especially in muscles of liver, and distributes evenly to rest of body, keeping body warm.

Answer 8

Oxygen. They can also carry intracellular dideases such as malaria, but I don't think that's what you meant by your question. All other nutients are either bound to proteins or move freely within the plasma portion of the blood.

Answer 9

they deliver oxygen and makes sure that blood is flowing throughout body

Answer 10

hi
they deliver oxygen to your body
