Immune System

Opossums are actually immune to the venom of many pit vipers including rattlesnakes, copperheads and cottonmouths. The reason for this immunity is due to ntihemorrhagic and antineurotoxic antibodies in their blood. Hope this answers your question :)

The first and second lines of defense are both components of innate immunity, that is defenses that are present at birth. The job of the first line of defense is to keep microbes out of the body. They include the skin, mucous membranes and their secretions and the normal flora. The second line of defense is activated once the microbe gets into the body. The second line of defense includes white blood cells (which "eat" invading microbes), inflammation (which is used to isolate the microbes and facilitate tissue repair), fever (which inhibits replication of microbes and enhances WBC performance), and antimicrobial substances.

A blood test is used to find out what components are in your blood and in what proportions. When they separate the solids they look at the red blood cell, white blood cell, and platelets. The monocytes are a common type of white blood cell, or leukocyte.

There must be hundreds of "rare kidney disorders" and data on them will be (well) rare to say the least!

Hypoplastic kidneys are small kidneys that contain a reduced number of normally developed filtering elements. The link gives more info. I'm sure there are treatment options.

no.. it does not... antibody works on specific immune response only...

Allergies

it specifically recognise the antigenic determinants called epitopes and the similar sequence of that particular epitope will be produced by the antibody at is variable region(specifically hypervariable region) whch make an antibody to get more affinity over that particular antigen..almost antibodies are available for almost all the antigens in our body(memory cells)and they starts increasing in numbr once an antigen enters our body

Advantage is that it gives a specific response. In a secondary exposure it responds so quickly you may not even feel sick. It is able to retain a long term memory against that specific pathogen as well.

Disadvantage is that primary exposure it takes 1-2 weeks to start producing a response against a foreign pathogen. Also it is possible for your adaptive immunity to attack self cells, also called autoimmunity.

These are called lymph nodes. Some people call them lymph glands but that is an incorrect term. They are a part of the lymphatic system, a component of the body's immune system. Swollen lymph nodes may signal an infection.

Immunity means the ability to resist. For example:to resist diseases Our body consists of immune system where the necessary cells some chemical substances consstantly offer resistance. Organs such as Thymus, spleen, lymphnodes, lymph vessels, bone morrow etc; Cells such as wbc, t-cells, b-cells, plasma cells, natural killer cells etc their chemical substances contribute to immunity and are parts and parcel of immune system. For better understanding please refer Dr. Janis Kuby's Text book "IMMUNOLOGY"

Antigens are substances that provoke an immune response (they're the ultimate target for the immune system). Antibodies are simply proteins that are secreted as a result of the antigen provoked immune response. In short, antigens cause the disease and antibodies cure it.

Once the vaginal blood comes in contact with the air, it is not uncomman for the blood to turn black. It is a process knowen as oxidation. ANSWER I have no idea about why it is black but when blood comes in contact with oxygen it becomes brighter red

In a sense, you are both kind of right. In red blood, iron is highly oxygenated. It is in its Iron(III) oxidation state, which is red. When Iron is reduced (oxygen taken away), it becomes Iron(II), which is black. This is usually due to breakdown of red blood cells. In this case, the blood within the uterus (womb) has been sitting there for a few hours before being expelled, and has broken down, causing the RBC iron to be reduced. This may be due to uterine contractions not being strong enough, or temporary blockage of the cervix.

Microglia function as phagocytes.

Those could be signs of pregnancy. If you haven't missed your period late, don't get too worked up about it. Wait until a few days after you miss your period and take a pregnancy test. Blood tests from a doctor are the most reliable.

These symptoms could also be caused by the influenza viruses.

a woman definitely does not want to assume she may be pregnant based on these symptoms alone. The chances of having the flu are probably higher than the chances of being pregnant. Frequent urination and diarrhea are also symptoms my mother suffered when she had fibroid tumers (?) in her uterus.

Most pathogens are mesophilic because they thrive inside of the human body. Mesophilic pathogens grow at an optimum temperature of 35-37 degrees Celsius, which is the normal human body temperature.

Iron.

Very carefully.

No, the first line of the immune system is the intact skin, mucous membranes and their secretions, normal microbiota all are physical barriers.

Basophils are circulating white blood cells that release histamine, but mast cells also do so.

yes. they contain antibodies which are vital in washing away germs and other pathogens and they stop microbes from infecting the cornea and other parts of the eye. they also wash away potentially infected foreign bodies from inside your eye.

The mother will be given Rhogam injection within 72 hours to prevent formation of antibodies to protect the 2nd baby that he will be conceiving.
