About 5 million cells per cubic mm in a healthy person.
White blood cells have. But erithrocytes lack many
Micron to millimetre is /1000. micron cubed to mm cubed is / a billion. Therefore this is 1mm3. 1mm3 is 2.64172x10-7 US gallons
infinite cells
My guess is no. Because a red blood cells do not have a nucleus in it and does not reproduce, centriole would have no purpose in it, because it does not need to be part of making spindles.
While the brain does not contain blood cells in the same way as blood vessels or circulating blood, it does have microglial cells that act as the immune cells of the central nervous system. These cells can help defend the brain against infections and remove cellular debris.
Only within the blood vessels. And there are many, many of those.
White blood cells have. But erithrocytes lack many
# why do blood cells have so many lysosomes?
Beta2-microglobulin is a protein found on the surface of many cells. Testing is done primarily when evaluating a person for certain kinds of cancer affecting white blood cells.
red blood cells. but there are also many white blood cells. not as many though.
In 1mm3 of blood, there is 5 million red blood cells (erythrocytes), 10,000 white blood cells (leukocytes) and 300,000 platelets (rarely known as thrombocytes). I answered a medical question and I'm only 15! Don't let that put you off. (Besides, I used a medical book to answer your question). 1mm3 is only a thousandth of a mL, therefore, 1mL of blood would have about a thousand times more of each. I.e. 5 billion RBCs, 10 million WBC, and about 250-300 million platelets
bones produce red blood cells, white blood cells, and platelets adults ,these cells of circulatory system are produce by RED BONE MARROW found in POROUS AREA of the bone in sternum
Fibroblasts are found in the dermis. They make the fibers that the dermis contains. There are many cells found in the blood vessels and nerve endings but they are not really considered to be dermal.
Blood cells are made in the bone marrow, which is located in the center of bones such as the hip, spine, and ribs. Red blood cells, white blood cells, and platelets are produced in the bone marrow. Additionally, during fetal development, blood cells are also made in the liver.

You are hit SON!!!!!!!! Answer: The human bloodcells are found only in the blood matrix plasma.There are three or more types of blood cells 1. red blood cells 2. white bood cells 3.lymphocyted(monocytes.basophiles etc)
there are 15 billion blood cells in your body
