The answer varies on how specific one wishes to go. Most generally, there exist 3 large groups of cells in the blood: erythrocytes, leukocytes, and thrombocytes.
Erythrocytes are simply red blood cells that are responsible for oxygen carrying.
Thrombocytes, better known as platelets, are small fragments of a huge myeloid derived cell known as a megakaryocyte. These are responsible for clotting.
Leukocytes break down into two major categories: Granulocytes (so named as they contain staining granules in microscopy) and agranulocytes (cells that don't have these)
Granulocytes then break into three cell types: Neutrophils (phatocytose bacteria/fungi), eosinophils (attack parasites), and basophils (involved in inflammation (allergenic/non-allergenic)).
Agranulocytes break down into three major categories: monocytes (macrophages), lymphocytes, and dendritic cells.
Monocytes are a class of phagocytic cell. They are however most famous for being the ancestors of the macrophage, the most famous phagocytic cell in the innate immune response.
Dendritic cells are phagocytic cells and are the most famous antigen presenting cell (APC). However, it is to be noted that only immature dendritic cells are found in blood; active ones only exist in tissue.
Lymphocytes are subdivided into B-cell (humoral immune response by antibody release) and T-cells (cell-mediated response), which themselves break down into helper T-cells (B-cell activation) and cytotoxic T cells (apoptosis of abnormal cells). All of these can be further subdivded into active and memory versions.
So "number of different cellular elements in blood" is a vague question at best, as there are too many methods of classification and differentiation to result in an appropriate answer.
An average human has approximately 5l (5000mm3) of blood.
Red Blood Cells (Erythrocytes) are found at an average concentration of about 5 million per mm3, so there will be approximately 25,000,000,000 (25 billion) in your blood.
White Blood Cells (leukocytes) are found at an average concentration of about 6000 per mm3, so there will be approximately 30,000,000 (30 million) in your blood.
Therefore, your blood contains approximately 25,030,000,000 cells.
Platelets are not real cells, but for the sake of argument, let's include them.
Platelets are found at an average concentration of about 250,000 per mm3, so there will be approximately 1,250,000,000 (1.25 billion) in your blood stream.
If you define platelets as cells, then there are about 26,250,030,000 (just over 26 billion) cells in your blood stream.
Human blood contains more than four thousand components. The most important being red blood cells, white blood cells, plasma and platelets. It are these four major components that deliver oxygen, fight infection, ensure blood clots and keeps the blood thickness at a proper level.
what are three cellular elements found in whole blood
Yes. The body has many types of cells. Here's some examples: Red Blood Cells White Blood Cells Plasma Cells
White blood cells have. But erithrocytes lack many
Phagocytic white blood cells contain a large number of lysosomes. These organelles contain enzymes that break down waste and cellular debris - which is why phagocytes (which engulf and digest things) contain many lysosomes.
Any cells can be used as you will find DNA in almost all of them (a few exceptions are red blood cells, platelets, etc.) but even where one specific cell in a tissue has no DNA many adjacent cells in the sample will have DNA.
The human sperm cell has 23 chromosomes. White blood cells have 46 chromosomes. Mature red blood cells to not contain a nucleus, and therefore has no chromosomes. Platelets are cell fragments and also do not contain nuclei.
Yes. The body has many types of cells. Here's some examples: Red Blood Cells White Blood Cells Plasma Cells
No , there are many types of blood cells .
White blood cells have. But erithrocytes lack many
there are many types of cells like the listed:dauter cells,blood cells,and many more.
There are many types of classifications, but the answer to your question is probably eukaryotes and prokaryotes. (However, it could be diploid and haploid or even just red blood cells and white blood cells).
There are two types of bone marrow: red marrow(consisting mainly of hematopoietic) tissue and yellow marrow (consisting mainly of fat cells).Red Blood Cels, platelets, and most white blood cells arise in red marrow. Both types of bone marrow contain numerous blood vessels and capillaries.
All living organisms are made of cells, or the littlist units of life. There are many different types of cells. (red blood cells, white blood cells)

There are many types of cells. Blood cells, for example, transport your blood (oxygen and other things as well) through your body, so you stay alive.
no. plants have specialization. they contain many different types of cells, including parenchyma, epidermis, pericycle, collenchyma, schlerenchyma, vascular: xylem-tracheids/vessels, phloem-sieve/companion cells, and many types of meristematic cells.
Phagocytic white blood cells contain a large number of lysosomes. These organelles contain enzymes that break down waste and cellular debris - which is why phagocytes (which engulf and digest things) contain many lysosomes.
Red blood cells and many white blood cells are made in bone marrow. (Some types of White blood cells are made in the spleen, live and lymph glands.)
