Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

Virus is a bloodborne infection in which the virus damages or kills the cells of the immune system?
Human immunodeficiency virus (HIV)
Why does type ab blood clump with anti-a and anti-b sera?
because ab red blood cells have both A and B sugars which bind to those sera. The anti a and anti b act as connectors between red blood cells, thus forming clumps.
What are pathogen micro organisms?
Pathogens are disease-causing micro-organisms, such as viruses and bacteria
What is the cause of increased segmenters?
Usually it's eating too many citrus fruits like oranges, clementines, manderins that tend to result in increased segmenters. If untreated, the skin can start to peel.
How does strptococcus pneumoniae avoid be killed by phagocytes?
explain how each of the following avoids being killed by phogocytes, S.pneumoniane, M.Tuberuclosis, S. dysenterae, S, pyogenes
Does a lymphocyte have a nucleus?
Yes, lymphocytes do have a nucleus. They need this nucleus because it will contain DNA necessary for protein synthesis and replication. Erythrocytes, RBC, on the other hand DO NOT have a nucleus and organelles because they do not need proteins and they do not replicate (undergo meiosis or mitosis), they are simply created from pluripotent stem cells in the bone marrow.
What is a system that fights disease and controls the immune response?
It is called the Immune System.
A bit of extra info: The Immune System is the cause of allergies. It goes too far when trying to protect the body from something.
ENDOCRINE SYSTEM
What can be the reason for Low neutrophil high lymphocyte and normal wbc?
Low Neutrophils High Lymphocytes
Low neutrophils and high lymphocytes are generally present in viral infection. The increased level of lymphocytes helps the body to fight the infection.
The following are the conditions for high lymphocytes:
Tuberculosis.
Acute leukemia. See also Symptoms of Acute myeloid leukemia
Mononucleosis
Ulcerative colitis.
Whooping cough.
Low neutrophil and high lymphocytes count is also seen in some kind of leukemia, but more commonly seen in virus disease and typhoid patients.
What is the difference between a pathogen and a contagion?
A pathogen causes a disease while a contagion spreads a disease by direct or indirect contact.
Which is least likely to be affected by a virus?
The least likely way to get affected is not using the internet, flash disks - disabling removable devices...however we both know this is not possible..
So you need to have an always updated antivirus. Implement proactive actions like scanning any removable devices before you open it....
Does aspirin depress the immune response?
yes..because it surely makes the nerves innactive a bit resultining in long term immune effect
There are not any websites where the answers to the incredible journey worksheets are provided. There are study guides available, just not any answers to the worksheet itself.
Nails and hairs do not have a network of blood vessels. They are mere accumulation of a protein called keratin. These proteins are neither associated with the circulatory system nor with the nervous system. Hence, we neither feel pain nor does it bleed when our nails and hair are cut.
What is the difference between agglutination and precipitation?
Agglutination involves the clumping together of insoluble molecules. So you easily this happening with the naked eye. Precipitation involves the aggregation of soluble molecules.
Who are what produces the antibody?
Antigens are responsible for producing antibodies.
An antigen (from antibody generator) originally defined as any molecule that binds specifically to an antibody, the term now also refers to any molecule or molecular fragment that can be bound by a major histocompatibility complex (MHC) and presented to a T-cell receptor. Self" antigens are usually tolerated by the immune system; whereas "Non-self" antigens are identified as intruders and attacked by the immune system. Autoimmune disorders arise from the immune system reacting to its own antigens.
RNA polymerase is an enzyme that makes a RNA copy from an RNA template.
supressor t cells
How many new cells are made from the one cell from meiosis in a human?
Two cells are made from one cell in meiosis. They both contain half the normal number of chromosomes (the haploid number.)
