Yes, blood is a special connective tissue consisting of fluid matrix,plasma,and formed elements.
The red and white blood cells along with platelets are collectively called formed elements.
As blood not only consist of blood cells but also other factors, we can't conclude that blood and blood cells are same.
A cell is the basic structural and functional unit of living organisms that can perform various biological functions. Corpuscle is a more general term used to refer to any small cell or particle, often used in the context of blood cells like red blood cells or white blood cells.
lymph caries digested and absorbed fat from intestine and drains excess fluid from extra cellular space back into blood. Lymph is basically blood plasma without the blood cells, the fluid that is forced out of capillaries to clean and nourish cells. The part of it that does not return to the blood vessels is picked up by lymph vessels and eventually returned to the blood.
in any given mm3 of blood, what is the approximate ratio of the number of red blood cells (erythrocytes) to white blood cells (leukocytes)
If human red blood cells are placed in a Ringer solution, which is an isotonic solution, they will maintain their normal shape and structure. The osmotic balance between the solution and the cells will prevent any swelling or shrinking of the red blood cells.
There is as much DNA in white blood cells as any other cell. There is none in red blood cells.
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.
No, there is no difference in appearance between DNA from different cells. DNA is a molecule that has a uniform structure regardless of the cell type it is found in. The only differences in DNA between cells come from variations in the sequence of nucleotides that make up the DNA.
In 1cm3 of blood, there are 5,000,000,000 red blood cells and 8,000,000 white blood cells. Meaning a ratio of 5000 to 8.
Only in the tiny blood vessels that feed the cells in those tissues.
Within humans, red blood cells and blood platelets do not have nuclei.
Alkalized cells use the alkali metal groups of the periodic table or the rare alkaline earth elements. Galvanized cells use any and all metals.
There are about a thousand times as many red blood cells as white cells. Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.
