Answer 1

Red blood cell: The blood cell that carries oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cell its red color (and name).
The mature red blood cell (RBC) is a non-nucleated biconcave disk. Thanks to this unusual shape and its hemoglobin content, the RBC is superbly suited to the transport of oxygen.
A red blood cell is sometimes simply referred to as a red cell. It is also called an erythrocyte or, rarely today, a red blood corpuscle.

White blood cell: One of the cells the body makes to help fight infections. There are several types of white blood cells (leukocytes). The two most common types are the lymphocytes and neutrophils (also called polymorphonuclear leukocytes, PMNs, or "polys").

Lymphocytes are made in lymphoid tissue in the spleen, lymph nodes, and thymus gland. There are different kinds of lymphocytes. Lymphocytes identify foreign substances from germs (bacteria or viruses) in the body and produce antibodies and cells that specifically target them. It takes from several days to weeks for lymphocytes to recognize and attack a new foreign substance.

Neutrophils are also major players in the body's defense against bacterial infections. Neutrophils are made in the bone marrow and circulate in the bloodstream. Neutrophils move out of the blood vessels into the infected tissue to attack the bacteria. The pus in a boil (an abscess) is made up largely of neutrophils. Normally a serious bacterial infection causes the body to produce an increased number of neutrophils, resulting in a higher than normal white blood cell count (WBC). When the WBC is low, there may not be enough neutrophils to defend against bacterial infections.

The white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis.

A normal absolute neutrophil count (ANC) is in the range of 1,500 to 8,000 cells per microliter. If the ANC is below 500 for an extended period of time, the risk of serious bacterial infection may increase significantly. A low neutrophil count is called neutropenia.

Answer 2

Both red and white blood cells are equally important. Red blood cells carry oxygen. White blood cells fight foreign objects in the body.

Answer 3

Red blood cells, also known as erithrocytes, are cells in charge of oxygen and carbon dioxide transportation, carrying a binding protein called hemoglobyn in their cytoplasms.
White blood cells are a group also calles leucocytes, wich primary divide in polimorphonuclear(thier nucelus can bedivided in several lobules, 2,3,4 or 5, this group include neutrophils, basophilsand eosinophils) and monomorphonuclear( linphocytes and monocytes are included here).

Answer 4

Red blood cells carry iron which carry oxygen to the other cells.
White blood cells fight infections.

Answer 5

red blood cells are the normal haemoglobin containing, spindle shaped cells of the blood. because of the overwhelming presence of the red coloured pigment haemoglobin in them they appear red in colour and ultimately impart the same colour to blood. another feature is that they do not have a nucleus. whereas white blood cells are the cells of our immune system present in the blood. they do not have a specific colour to impart but they do have granules which when stained with a proper stain would impart colour to them. they have a definate nucleus. there are many subtypes of these types of cells explaining which are out of the scope of my reply.

Answer 6

Red blood cells (RBC) carry oxygen and they contain haemoglobin.

White blood cells (WBC) are immune cells that fight against infections in the host system.

Answer 7

Red blood cells (RBC) and white blood cells (WBC) are cellular components of blood. RBCs are responsible for the transport of oxygen to the different parts of the body , while WBCs are responsibe for immune responses.

Answer 8

White blood cells fight and keep germs out.
Red blood cells carry oxygen throughout your body

Answer 9

R. B.C ;THESE ARE CIRCULAR IN SHAPE AND CONTAIN A RED COLOURED PIGMENT CALLED HAEMOGLOBIN THEY CARRY O2 TO THE TISSUES AND BRING BACK CO2 FROM THE TISSUES.

Answer 10

Erythrocytes and leucocytes.
