Blood

Red blood cells (RBCs) do not release chemicals that directly form fibrin. Instead, fibrin formation is primarily part of the coagulation cascade, which involves platelets and various clotting factors. When a blood vessel is injured, platelets aggregate at the site and release substances that activate these clotting factors, ultimately leading to the conversion of fibrinogen to fibrin, which helps form a stable blood clot. While RBCs are involved in the overall process of hemostasis, they do not participate in the chemical reactions that create fibrin.

This from: Center for Eosinophilic Disorder at Cincinnati's Children's Hospital @ http://www.cincinnatichildrens.org/svc/alpha/e/eosinophilic/about/conditions.htm There are many disorders where the eosinophils have been found elevated either in the blood or in different tissues. The experts in the Cincinnati Center for Eosinophilic Disorder at Cincinnati Children's Hospital Medical Center provide a list of general categories of diseases with some examples included. Allergic Disorders: Allergic disorders are classically characterized by presence of eosinophils. Allergic rhinoconjunctivitis (hay fever) has increased levels of eosinophils in the nasal mucosa. Asthma, after an exacerbation, shows increased eosinophils in the lung. Drug Reactions: Any drug/medicine can precipitate a reaction. Some of these reactions are allergic in nature and eosinophils might be elevated in blood or in tissues where the drug is concentrated. Infectious Diseases: Parasitic infections (Helminthiasis-worms), fungal infections and some other types of infections are associated with increased eosinophils. Blood Disorders: A few examples of hematologic disorders with increased esoinophils include the hypereosinophilic syndrome, leukemias, lymphomas, tumors, mastocytosis and atheroembolic disease. Immunologic Disorders and Reactions: Hyper-IgE syndrome, Ommen's syndrome, thymomas, transplant rejections are only a few types of conditions with increased eosinophils. Endocrine Disorders: Hypoadrenalism has been associated with blood eosinophilia. • • • • • • • • • Specific Organ Involvement: Below are certain conditions organized by the organs/tissues that are affected where eosinophils have been found to be increased or pathologically present. Skin and subcutaneous disorders Atopic dermatitis (eczema), bullous pemphigoid, pemphigus vulgaris, dermatitis herpetiformis, drug-induced lesions, urticaria, eosinophilic panniculitis, angioedema with eosinophilia, Kimura's disease, Shulman's syndrome, Well's syndrome, eosinophilic ulcer of the oral mucosa, eosinophilic pustular folliculitis and recurrent cutaneous necrotizing eosinophilic vaculitis. Pulmonary conditions Drug/Toxin-induced eosinophilic lung disease, Loeffler's syndrome, allergic bronchopulmonary aspergillosis, eosinophilic pneumonia, Churg-Strauss syndrome, eosinophilic granuloma, pleural eosinophilia. Gastrointestinal diseases Gastroesophageal reflux, parasitic infections, fungal infections, Helicobacter pylori infections, inflammatory bowel disease (ulcerative colitis and Crohn's disease), food allergic disorders, protein-induced enteropathy and protein-induced enterocolitis, allergic colitis, celiac disease, primary eosinophilic esophagitis, gastroenteritis and colitis. Rare tumors (leiomyomatosis), connective tissue disorders and vasculitic disorders. Neurologic disorders Organizing chronic subdural hematoma membranes, central nervous system infections, ventriculoperitoneal shunts, drug-induced adverse reactions. Rheumatologic illnesses Eosinophilic synovitis, eosinophilia-myalgia syndrome, vaculitic disorders such as the Churg-Strauss Syndrome. Cardiac conditions Heart damage has been reported secondary to systemic disorders such as the hypereosinophilic syndrome or the Churg-Strauss syndrome. Certain congenital heart conditions (septal defects, aortic stenosis) are associated with blood esoinophilia. Renal diseases Eosinophiluria (eosinophils in the urine) associated with infections or interstitial nephritis and eosinophilic cystitis.

Blood supplies oxygen and nutrients to all parts of the body.

they have no regular shape.

they have a nucleus.

Blood pressure measures the pressure (force per area) on the arterial walls during the contraction and relaxation of the heart.

Systolic blood pressure, the top reading of the reading, measures the pressure on the arterial walls while the heart undergoes systole. Systole refers to the heart contracting. The diastolic blood pressure - bottom reading - gives us the pressure on the arterial walls during diastole. Diastole is the opposite of systole - the heart relaxes and fills with blood for the next contraction.

Yes. The normal range or reference interval for Neutrophils is between 40 - 74. My lab results read me at 76 as well; this indicates your body fighting some form of bacterial infection.

The main purpose of blood going dry is to heal wounds by reacting with the oxygen in the air.

Diffusion

Venous blood flow is easiest to control. Arterial blood flow is hardest to control because it is under pressure from the heart.

Iron plays a critical role in the formation of hemoglobin.

yes, they get it back by pumping blood to the 4 parts of your heart. when you inhale, it makes rich blood when you exhale it takes out poor blood which turns into carbon dioxide.

well blood consist of mostly water and water is made up of H2O, which means 2 hydrogens and one oxygen atom. Which this means it size is 3 atoms. Now if you take a look at all the other stuff in blood you can see that it is far more bigger than that. So if the blood is filterd small enoth that nothing but water can get past but yet big anoth that a object the size of 3 atoms can go past then thewater will be separated from the blood living the rest of the blood. So when water turns to blood all it means is that the water is seperateing from blood so they blood in fact has not turnent in to water but insted the water has been filterd out the blood

That's your dermis. It's between the epidermis and the hypodermis (the fat).

You probably have a deviated spetum bleed often caused my using massive amounts of Cocaine.

Whoever wrote the above answer obviously isn't a doctor because I have never used Cocaine a day in my life and I sneezed a small amount of blood this morning.

Sometimes an infection can cause such a high white cell count. In that case the count comes after properly treating the infection. If it persists other investigations may be required to find out the cause.

platelet distribution width (PDW)an indication of variation in platelet size which can be a sign of active platelet release.

Acute leukemias develop and progress rapidly, while chronic leukemias develop slowly and have a better prognosis. If someone was diagnoed with leukemia, the blood smear and other tests can indicate if this patient have chronic or acute leukemia.
