Critical thinking questions: 1. Although not pictured in the model above, the first thing that happens when a blood vessel is torn is vasospasm, in which the walls of the blood vessel contract. As a group, come up with an explanation for this phenomenon.…
3. How is blood type determined? What happens if someone is given the wrong type of blood in a blood transfusion?…
Haemostasis is the body’s way of stopping injured blood vessels from bleeding. Haemostasis includes clotting of blood. When blood clotting is poor even a slight injury to a blood vessel may lead to severe blood loss. Haemostasis involves three major procedures…
These cytokines cause inflammation because they cause vasodilatation which makes blood rush to the injured site.…

Protection: Circulates antibodies and defensive cells to combat infection and disease, also produces clots to prevent excessive loss of blood.…
White blood cells help to defend against pathogens by: 1. Engulfing it; 2. Producing Anti-Bodies; 3. Producing Anti-Toxins…

Overlapping heparin or enoxaparin therapy is especially important in patients who have a much more risk factor to thrombotic events such as patient with protein C or S deficiency and also patient who metabolizes Coumadin more rapidly than the average person. (Heit et. al. 2011)…

The four main components of blood are Red blood cells, White blood cells, Platelet and Plasma. The red blood cells contain hemoglobin, a protein that binds oxygen. Red blood cells transport oxygen to, and remove carbon dioxide from, body tissues. The white blood cells fight infection. One type of infection-fighting white blood cells fight disease by producing antibodies and thus destroying foreign materia. The platelets help the blood to clot, if you get a wound for example.…
Hemophilia is the most common inherited coagulation disorder. Although hemophilia is commonly inherited, it can also occur due to a spontaneous mutation. Hemophilia A is an X-linked, recessive disorder caused by a deficiency of Factor VIII. Hemophilia can be severe, moderate, or mild. Individuals diagnosed with severe hemophilia A are typically diagnosed early in life, prior to age two. This is diagnosed particularly following episodes of bleeding from mouth injuries and bumps on the head. Spontaneous bleeding may occur as well as prolonged bleeding from injuries. Roughly five episodes of spontaneous or prolonged bleeding can occur each month. In cases of moderate hemophilia A, individuals have delayed clotting after minor injuries,…
Inflammation is a protective response by the body towards cell injury, irritation, infection and can accumulate fluids with the following signs and symptoms: redness, warmth, swelling and pain. Inflammation is therefore the body’s way of attempting to remove the primary cause of inflammation and any damage that may have occurred as a result (healing and repair) (Drake et al., 2007). Today numerous drugs are used to treat conditions of inflammation such as narcotics (opioids), and non narcotics (salicylates), however these drugs accumulate side effects. That is why drugs from natural sources are referred to be a better inflammatory agent considering the presence of low toxicity and its therapeutic value. Natural drugs are considered as a big…
