Overview on the blood
Blood: is a fluid that consists of red blood cells, white blood cells, plasma and platelets, the body of the person 8% of the blood, the blood from the tissues major functions of paramount importance in the human body.
What is the function of blood?
Blood carries the following to the body tissues:
The immune cells (cells that fight infection).
Blood moves the following away from body tissues
What are the components of blood?
The components of human blood are:
Plasma: the liquid component of the blood in which red blood cells and white blood cells are present.
Red blood cells: the function of these cells carry oxygen from the lungs to the rest of the body get rid of carbon dioxide.
White blood cells: these cells help fight inflammation and help the immune process.
Types of white blood cells include
Basal cells (Basophils).
Platelets (clots). These help in blood clotting and stop the bleeding.
Where are blood cells made?
Blood cells are made in the bone marrow. Bone marrow: is the spongy material that is found in the middle of the bone and that makes all kinds of blood cells.
There are other organs and systems in the body that help regulate blood cells. Lymph nodes, spleen and liver help regulate the production and destruction of cells. The production and development of new cells in the bone marrow is a process called blood cell production.
Blood cells formed in the bone marrow begin as stem cells. Stem cell: is the first phase of all blood cells. As the stem cell matures, several characteristic cells develop. These include cells (red blood cells, white blood cells, platelets). Also called immature blood cells (blasts). Some bangs remain in the marrow until ripe. Other (immature) cells move to other parts of the body to develop into mature blood cells.
What are the functions of blood cells?
The main function of red blood cells, transport oxygen from the lungs to body tissues and carbon dioxide as waste, away from the tissues back to the lungs. Hemoglobin (Hgb) is a protein important in red blood cells which transports oxygen from the lungs to all parts of the body.
The main task of white blood cells is to combat infection. There are several types of white blood cells and each has its own role in fighting bacterial and viral infections, fungal and parasites. The most important white blood cell types to help protect the body from infection and foreign cells include:
Basal cells (Basophils)
Platelets (clots). These help with blood clotting
What is complete blood cell count (CBC)?
Red blood cell count is a measure of the size, number and maturity of different blood cells in a blood sample. You can use CBC to find problems in the production or destruction of blood cells. Differences in the normal number, size, or maturity of blood cells can be used to mean an infection or a pathological process.
Scan uses the CBC to help diagnose anemia and blood disorders other cancer and certain blood, to monitor blood loss and infection, or to monitor response to cancer treatment, such as chemotherapy and radiation.
Often with an infection, you will raise the number of white blood cells. Many forms of cancer can also affect blood cell production. For example, an increase in immature white blood cells in CBC can be associated with leukemia. Blood diseases, such as anemia and sickle cell disease, will cause hemoglobin to drop abnormally.
White blood cells
Blood:a fluid found in the body consists of red blood cells, white blood cells and platelets and plasma.
White blood cells account for only about 1% of the blood, but their effect is significant. These cells protect against foreign bodies. Rob white blood cells to help destroy harmful substances and prevent disease.
White blood cells are made in the bone marrow. They are stored in the blood and lymph tissues. Since the age of white blood cells varies from one to three days, the bone marrow always makes them.
White blood cells consist of:
Monocytes : no longer lifespan than many white blood cells and help to break down bacteria.
Lymphocytes: consist of antibodies to fight bacteria, viruses and other potentially harmful microorganisms.
Neutrophils: kill and digest bacteria and fungi. It is the most white blood cell type and the first line of defense when infection occurs.
Basophils are cells that secrete chemicals such as histamine, a sign of allergic disease, which help control the body's immune response.
Eosinophils : attack and kill parasites and cancer cells, and in allergic responses.
Problems affecting white blood cells:
The number of white blood cells can be low for several reasons. Low white blood cells include when something destroys these cells more quickly than the body's ability to regenerate them. Or when it stops bone marrow from producing enough white blood cells to maintain health. When the number of white blood cells is low, just be the person at great risk for any disease or infection.
Can Technician Laboratory blood test to see if the number of white blood cells is normal or not. If the number of cells is too low or too high, you may have the disorder in white blood cells.
Diseases and conditions that affect white blood cell levels
Weak immune system: weak immune system often due to diseases such as HIV (AIDS) or due to cancer treatment. If cancer treatments such as chemotherapy or radiation therapy can destroy the white blood cells and the person becomes at risk of injury.
Infection: white blood cell count higher than normal, usually means that you have some kind of infection. Multiply white blood cells destroy bacteria or virus.
Myelodysplastic syndrome: this condition causes abnormal production of blood cells. This includes the white blood cells in the bone marrow.
Leukemia: cancers including leukemia and lymphomas can cause uncontrolled growth of an abnormal type of blood cell in the bone marrow. This leads to a significant increase in the risk of infection or severe bleeding.
Spinal cord proliferation defect: this defect refers to various conditions that lead to over-production of immature blood cells. This imbalance can leads to an unhealthy balance of all types of blood cells in the bone marrow and too much or too little white blood cells in the blood.
Medications: some medications can raise or lower the number of white blood cells in the body.
Cases like severe physical stress caused by injury or emotional stress can lead to high levels of white blood cells. So inflammation, Labor, the end of pregnancy, or even intense exercise can occur.
What are red blood cells?
Red blood cells transport oxygen throughout the body, red blood cells are round-shaped cells. The lab technician can also confirm the size, shape and health of red blood cells using a blood test (CBC).
The function of red blood cells
Hemoglobin: is a protein found inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from the body, transporting it to the lungs so you can exhale and get rid of it.
Red blood cells are made in the bone marrow. The life cycle of red blood cells is usually approximately 120 days, then the cells die.
Nutrition and red blood cells
Iron-rich foods help keep red blood cells healthy. Vitamins are also needed to build healthy red blood cells. These include B-2, B-12 and B-3 vitamins found in foods such as eggs, whole grains and bananas. Folic acid B-3 also helps build red blood cells. It is found in fortified cereals, dried beans, lentils, orange juice and green leafy vegetables.
