Main differences in o positive,and o negative?
The positive or negative in the blood types refer to the Rh factor, which is an antigen. Antigens trigger immune responses. Being positive or negative for the Rh factor will impact who you can receive a blood donation from, and who you can donate blood to.
Why there is no reaction against Rh factor on first transfusion?
There is no reaction against the Rh factor during the first blood transfusion because the recipient's immune system has not yet been sensitized to the Rh antigens. When Rh-positive blood is transfused into an Rh-negative individual for the first time, their body does not have pre-existing antibodies against the Rh factor, allowing the transfusion to occur without an immediate immune response. However, if an Rh-negative person is exposed to Rh-positive blood again, their immune system may recognize the Rh antigens and mount a reaction.
Does o- blood effect pregnancies?
Each person's blood is one of four major types: A, B, AB, or O. Blood types are determined by the types of antigens on the blood cells. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. The Rh factor is a type of protein on the surface of red blood cells. Most people who have the Rh factor are Rh-positive. Those who do not have the Rh factor are Rh-negative
How does cannabis get to the brain?
cannabis flows through the blood stream in to your brain and makes your nervous sysytem faster
Where is the Immune system in your body?
The immune system is all over. White blood cells are part of it and are in your blood.
What is the blood cell protein that elicits an immune reaction?
The protein that elicits an immune reaction in blood cells is called an antigen. Antigens are typically foreign substances that trigger an immune response when they are detected by the immune system.
Can Rh negative patient receive Rh negative blood?
No. Blood type is determined by a couple of things. The first are the antigens present on the red blood cells. This is where you get A, B, and AB blood types. If you lack either A or B antigens, you have an O blood type. The +/- refers only to the Rhesus factor D, or RhD. It does not refer to other rhesus factors that are not considered in blood type. With this factor, you either have it on your blood cells (+) or you do not (-). It is impossible to have a positive blood type and not have rhesus factor D because that would be a complete contradiction to the naming system.
In the human immune system the main function of what organ is filtering blood?
in the human immune system the main function of the is filtering blood
What blood cells are part of the immune system?
White blood cells are part of the immune system's defense. White blood cells flock to irritations and infections to heal or eliminate them.
What characteristics does a normal immune complex test have?
Normally, immune complexes are not detected in the blood.
What are the principle cells of the immune system and what is their role in the immune response?
The principle cells of your immune system are lymphocytes, or white blood cells. The immune system, however, is highly complex, and it is difficult to single out one type of cell for importance. All of the components have to work together in harmony for optimized function.An immune response is generated when you are exposed to a foreign pathogen. Examples of this would be a virus, bacteria, parasite, or fungus. Your immune system's job is to recognize the invader and destroy it. In this case, the lymphocytes, or white blood cells, engulf the pathogen and eat it up, keeping it from multiplying and making you sick.You want as many of these white blood cells as you can get when you are fighting off an infection. The rate limiting factor in the production of lymphocytes and the strength of your immune system is a protein called glutathione.
Does Rh contain the rhesus protein?
Yes, Rh refers to the Rhesus factor, which is a protein found on the surface of red blood cells. Individuals who have this protein are classified as Rh-positive, while those who do not are Rh-negative. The presence or absence of the Rh factor is important in blood transfusions and pregnancy, as it can lead to immune reactions if mismatched.
