state 2 major sstructural differences between the R.B.C and the W.B.C?

Answer 1

Very Easy...
1: RBC:no nucleas WBC:nucleas
2: RBC:no mitochondia WBC:mitochondria

RBCs rely on glucose only for glycolsis, not Kreb cycle happens. Haemglobin is present in place on a nucleas

Answer 2

The major difference between the RBC's and the WBC's is that the Nucleus is absent in the RBC. Another structural difference is that RBC have capacity to bind up with oxygen while WBC play a effective role in immunization.

Answer 3

Erythrocytes (Red Blood Corpuscles).
In humans there are about 5 million erythrocytes per cubic millimetre of blood. Erythrocytes are small, round, bi-concave discs which float in the blood plasma. They are actually yellowish in colour but when present in large numbers they are red. Each adult red blood cell represents a cell without a nucleus, which is surrounded by a thin, elastic membrane. They are soft, flexible and elastic and therefore move easily through the narrow blood capillaries. Approximately 90% of the content of each erythrocyte is haemoglobin which supplies the characteristic colour of the red corpuscles. Red blood cells are formed in the red marrow of long and flat bones, especially in the spongy regions in the heads of the long bones. The life span of an erythrocyte is approximately 4 months.

Functions
The erythrocytes transport oxygen in the blood from the lungs to all the cells and tissues of the body.
Red blood corpuscles also assist with the transport of carbon (IV) oxide from the tissues to the lungs.
They play an important role in regulating the acid-base balance of the blood, thus preventing large changes in pH.
Erythrocytes also assist when a blood clot is formed.


Leucocytes (White Blood Cells).
Leucocytes are far less numerous than red blood corpuscles. Leucocytes are larger than red blood corpuscles and have a definite nucleus. They are irregular in shape, slightly translucent and nearly colourless.They are able to change their shape because of the fact that they move by means of pseudopodia (false feet). Many are phagocytic, i.e. they are able to engulf micro-organisms and foreign intruders into their cytoplasm by flowing around them. There are five types of leucocytes which can be divided into two groups, namely granular white blood cells where the cytoplasm is granular, and non-granular white cells where the cytoplasm does not contain granules. The two principal types of white blood cells are neutrophils and lymphocytes. Neutrophils are the most abundant and are produced in the red bone marrow. Their nuclei are divided to form 3 to 5 lobes, connected by thin threads of nuclear material. They all have conspicuous granules in their cytoplasm. Eosinophils and basophils also have granules in their cytoplasm and irregular-shaped nuclei. Lymphocytes are produced in the spleen, tonsils and lymph nodes and are the smallest of the white blood cells. There are no granules in the cytoplasm but a large spherical nucleus is present.

Functions
Neutrophils are active in phagocytosis and defend us against harmful viruses, bacteria and other foreign intruders.
Neutrophils also play a role in the healing of wounds and repairing worn out and damaged tissues.
Neutrophils prevent infections from spreading to other tissues of the body.
Lymphocytes are involved in the synthesis and distribution of antibodies in the blood. The B-cells are responsible for humoral or antibody immunity. The T-cells are responsible for cellular immunity.

Answer 4

Red blood cells are sort of round like Cheerios and full of hemoglobin and white blood cells are shaped wobbly like Casper the ghost and there are half a dozen types of these. They perform no role in Geology that I know.
