Because erythrocytes carry oxygen (and carbon dioxide too, but C02 attaches to the protein portion of hemoglobin, not the iron portion). Our cells need to get rid of carbon dioxide and use oxygen to survive. Leukocytes are more focused on protecting the body from foreign invaders, like bacteria and parasites. They also clean up debris from wounds. But although this is important, it isn't as necessary to our immediate survival as getting rid of C02 and getting oxygen into our cells. Look at it this way -- we can survive about 3 minutes without oxygen. Without any of our white blood cells, we can probably survive a couple of hours before dying from infection.

Are there more erythrocytes than leukocytes?
In blood there are more erythrocytes (red blood cells) that leukocytes (white blood cells)
Compare and contrast erythrocytes and leukocytes Be sure to include similarities and differences of structure and function?
Erythrocytes are larger than leukocytes. Erythrocytes have no nucleus while leukocytes have nucleus. Leukocytes remove and/ or destroys things that are considered "abnormal" in the body while erythrocytes carry oxygen to all body cells. Leukocytes are large round cells that do not contain hemoglobin while erythrocytes contain hemoglobin, are shaped as biconcave disks that bend, flex travel through narrow blood vessels and have a large surface to volume ratio. Erythrocytes and leukocytes are both classified as formed elements (lower layer). They both are main components of the body are necessary for the body to function properly.
Why are there more erythrocytes in the blood than leukocytes?
Erythrocytes are red blood cells, contain hemoglobin, and carry oxygen to the cells and tissues and carbon dioxide back to the respiratory organs. Leukocytes are white blood cells and participate in immune function.
What is the percentage of erythrocytes in blood known as?
Erythrocytes make up about 45% of the blood Plasma makes up the other 55% and a Buffy coat consisting of leukocytes and platelets makes up less than 1%
How many leukocytes are present in?
There are 5 leukocytes in the human body. They include: Eisinophil, basophil, neutrophil, lymphocyte and monocyte. The leukocytes that end in "phil" are more granular than the cytes.
Does blood contain red blood cells and blue blood cells?
In relation to the human body, it is a common misconception that blood is blue; all blood is red. The blue appearance is due to the connective tissues of the blood vessels. Blood cells can be either erythrocytes, which are red, or leukocytes, which are white. When blood is oxygenated it is a much brighter red than de-oxygenated blood.
Fluid other than blood that carries leukocytes?
It's lymph.
When the total number of leukocytes in the circulating blood is less than normal?
Leukopenia
What are similarities between the human blood smear and the frog blood smear under microscope?
Numerous differences can be seen between frog blood and human blood. Perhaps the most obvious is the oval shape of the frog erythrocytes rather than the biconcave discs of human blood. Moreover, the frog erythrocytes have a nucleus (here stained blue) whilst human erythrocytes do not. There is less difference in size between the erythrocytes and leucocytes than in human blood. There are no platelets in frog blood.
What leukocytes usually accounts for less than 1 of white blood cells present?
basophils
Do female have more white blood cell than male?
There are many more red blood cells than white.In one cubic millimeter of human blood, there are from 4 to 6 million red blood cells (RBCs, or erythrocytes).By contrast, in the same volume you will find only 4,000 to 11,000 white blood cells.
All leukocytes contain only a single nucleus so when observed under a microscope why does it appear that some of the leukocytes have more than one nucleus?
They contains granules in its cytoplasm, and cell splitting may be occuring.
