Basic structure of a cell: -

The cell is a basic microscopic unit of our body. Visible only by a microscope, various parts of the cell can be seen and analyzed. A cell consists of basic elements like nucleus, cytoplasm, cytoplasmic inclusions and these elements are covered by a cell membrane. The nucleus contains a DNA that controls all the cell functions and allows it to respond to the environment. The cytoplasm that surrounds the nucleus contains small structures that make proteins, structures that supply the cell's energy, molecules that transport energy, chemical messengers, and many other functional elements, as well as storehouses of enzymes and other substances. The cell membrane controls the flow of substances in and out of the cell. It also contains the molecules called antigens that are specific to the cell and the person.

In human vertebrates, the RBC is with out a nucleus. It is only present in certain species of camel. Thus the replication of the RBC is not possible due to lack of nucleus. The nucleated Red Blood Cell contains Basilophilic stippling in its center. This is the indication for the toxic injury of the bone marrow. This may also be due to megloblastic anemia. These appear in irregular shapes and are similar to 'helmet cells'. This is peculiar for disseminated intravascular coagulopathy (DIC). The peripheral blood shows presence of large bluish Reticulocytes. If the smaller red blood cells lack central pallor spherocytes then the patient is suffering with autoimmune hemolytic anemia. Generally the count of these reticulocytes is reduced to twenty percent. The individual gains a certain amount of an indirect hyperbilirubinemia. The peripheral blood appears like tear drop cells, this may lead to myrofibrosis. This RBC center may become home to Howell-Jolly bodies that are the nuclear chromatin remnants. These may also occur in infants due to smoking habits of the pregnant mothers

White Blood Cells (WBCs) are extremely crucial in the human body. They play a fundamental role in the normal well being of the human body. It is necessary to have a specific WBC count for an individual to remain healthy. However, a minor change in the WBC count can have disastrous effects, the most prominent effect being that of cancer.

Cancer Due to WBCs

The human body is a complex structure made up of several major and minor components. Apart from the major organs like the heart, the brain, the kidneys and several others, even the minute cells, arteries and veins play a significant role in the smooth functioning of the body. Cells especially perform a fundamental role in maintaining the health of the individual. An imbalance in the cells can cause major health disorders.

Effects of Low White Blood Cell Count

The stem cells have the totipotent tendency. Thus they define the properties of meristematic tissue. The umbilical cord blood is human blood from the placenta and umbilical cord that is rich in haemopoeitic stem cells. The umbilical cord is the narrow tube line structure that connects the developing baby or the fetus to the placenta. This is rightly called the baby's lifeline. The versatility and the availability of the umbilical cord cells make them the potent resource for the transplant therapies. The cord blood stem cell is more proliferating and higher chances of compatibility than the bone marrow transplants.

White blood cell is one of the components of blood or plasma. Blood is a circulating tissue. It is responsible in carrying nutrients and other vital elements to the different body tissues. Along with white blood cells, red blood cells and platelets compose blood. However, White blood cells are bigger than red blood cells and are normally fewer in number.

White blood cells

White blood cell (WBCs) is one of the components of blood or plasma. These cells are also known as leukocytes. The white blood cells are produced in the bone marrow of large bones. Generally, each drop of blood contains approximately 7000 to 25000 white blood cells.

Types of white blood cells

White blood cells are mainly of five types; neutrophils (40% – 75%), eosinophils (5%), basophils (0.5%), lymphocytes (20% – 50%) and monocytes (1% – 5%). Out of these, netrophils, eosinophils and basophils are granulocytes. Where as, lymphocytes and monocytes are agranulocytes. Granulocytes are those WBCs which have granules in their matrix and which get stained. On the other hand, agranulocytes are those which do not have granules in their matrix and which do not get stained.

Red blood cells are the most common blood cells present in the human body. They perform the function of delivering oxygen from the lungs to the different body tissues and vice-versa. Most of the vertebrae contain red blood cells. Red blood cells or RBCs are also known as erythrocytes.

Composition of RBCs

The WBC's as they are commonly known are also called as Leukocytes or white cells or white corpuscle. Essential for the proper functioning of the immune system, they are found in the blood stream of our body. Some white blood cells act as scavengers by engulfing foreign particles and destroying them. Others produce antibodies or destroy dead cells. Normally produced in the bone marrow, these cells are also known as the antibodies.

Count of WBC's

Blood is a circulating tissue composed of fluid plasma and cells. It carries nourishment and oxygen to the various tissues and takes away carbon dioxide and wastes. Whole blood is a mixture of blood cells and plasma. The blood cells include erythrocytes (red blood cells), leucocytes (white blood cells) and platelets (thrombocytes).
There are various diseases infecting the blood cells. Blood cell cancer is one of the most dangerous of the kind. Diseases of the blood affect the way he body makes blood and provides immunity from other diseases.

Blood Cell Cancer

The major forms of blood cancer are Lymphoma, Leukemia and Multiple Myeloma.

What are red blood cells?

Red blood cells are those which carry oxygen from the lungs to the rest of the body. They also carry carbon dioxide back to the lungs. So it can be exhaled. If the RBC count is low the body may not be getting the oxygen it needs. If the count is too high, there is a risk that the red blood cells will clump together and block tiny blood vessels. The body contains more of red blood cells than any other type of cell and each red blood cell has a life span of about 4 months. Each day, the body produces new red blood cells to replace those that die or are lost from the body.

Red Blood Cells are actually the life-carriers in the human body. They carry oxygen to various parts of the body. They contain the vital hemoglobin, which is so much important for the body to remain healthy. Thus, the role of RBCs is beyond priceless. However, RBCs have a particular life-span. After their stipulated life-span ends, they are replaced by new blood cells.

Life Facts

Blood is a circulating fluid. Blood cell is any type of blood found in the blood or plasma. In mammals blood also known as plasma is made up of three types of blood cells. Namely, the red blood cells, the white blood cells and platelets. The main function of blood is to supply nutrients and other elements to the different body tissues.

Red blood cells

White Blood Cells are a significant component of the human body. Without these cells functioning properly, the human body cannot remain fit and healthy. An imbalance in the count of these cells leads to a huge body disturbance and great disorders. A low or a high white blood cell count can result in tremendous grave health problems. Especially, a high white blood cell count can result in life-threatening consequences.

Effects of High WBC Count

Blood is the life-giving fluid, transporting oxygen and nutrients to the body tissues. It is a connective tissue, proteinaceous in nature. Blood consists of various components including fluid plasma and blood cells. The blood cells comprise the erythrocytes (red blood cells), leucocytes (white blood cells) and platelets (thrombocytes). Diseases of the blood can affect one or all of the blood cells. Other kinds of blood diseases affect proteins and chemicals in the plasma that are responsible for clotting.

Diseases Of The Red Blood Cells

There could be innumerable reasons for this problem. The WBCs present under the normal forms is up to 5WBC/HPF.The majority of WBCs are neutrophills. Eighty five percent of all the Urinary Tract infection is caused By E.coli, ten percent is due to Kleibsella, Prosteus and five percent is around Staph aureus, fungus, TB, Chlymadia etc. The WBC is unattained sediments in the urine. These are round with a granular matrix and measure about 1.5 to 2.0 times that of a RBC. The higher number of WBCs is called Pyuria, This indicates the presence of an inflammatory process in the urinogenital tract in the body. The diagnosis is done by specific gravity, pH, protein, glucose, ketones, blood, leucocytes esterase, bilirubin and urobilinogen. For girls 10WBC/cu mm is considered to be abnormal and indicative of pyuria or acute form of Glomerulonephritis.

The WBC's as they are commonly known are also called as Leukocytes or white cells or white corpuscles. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes. They are a group of several cell types that occur in the bloodstream and are essential for a proper functioning of the immune system. Some white blood cells act as scavengers by engulfing foreign particles and destroying them. Others produce antibodies or destroy dead cells. They are normally produced in a bone marrow.

Types of White Blood Cells

There are many types of WBC's. The basic types are as follows….

It would be an understatement to say that blood cells are extremely crucial in the human body. Blood cells are blood carriers in the human body. In the human body, blood flows through arteries and veins. This system provides blood to the entire body. These arteries and veins carry blood different types of blood cells.

Types of Blood Cells

There are basically three types of blood cells in the human body. They are namely, Red Blood Cells (RBCs), White Blood Cells (WBCs) and Platelets. Most of these cells are produced in the bone marrow in the human body. Especially, the bone marrow in vertebrae, ribs, skull, sternum and pelvis produce the majority amount of blood cells. These cells pass through plasma in all the parts of the body.

The standard human peripheral blood mononuclear cell isolation media like that of lymphoprep or Nycoprep 1.077 are less effective for the isolation of these cells from the blood of certain experimental animals. The density of the Peripheral blood mononuclear cell from mice, rats and rabbits is actually slightly higher than that from humans. Some commercial media simply address this problem by having an equally raised density. This simple solution however fails to address the instantaneous problem that the density of the polymorphonuclear leukocytes is the same. Thus although recoveries of Peripheral blood mononuclear cells are satisfactory, contamination from PMNs can be important. The basic aim or the background of the study is to investigate the role of peripheral blood mononuclear cells in embryo invasion at the implantation site and to estimate the effect on PBMC function of human chorionic gonadotrophin that is secreted from the human embryo.

Red Blood Cells are the most common type of blood cells. Also known as the RBC's or enthrocytes principal means of delivering oxygen from the lungs to body tissues in a human body. A single drop blood contains millions of red blood cells which are constantly traveling through your body delivering oxygen and removing wastes. The absence of the red blood cells in our body would mean that you are virtually non-existent as you would surely die of suffocation.
