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.

How does the body react to pathogens?
the body does not react well to bacteria. It can be harmful to your body and can start disease
What 5 ways do pathogens spread?
Diseases can be transmitted by touch such as via a handshake between an infected and uninfected person, blood and other bodily fluids in example an infected blood transfusion, sexually transmitted which can occur from oral vaginal or anal sex, aerosol also known as respiratory which can occur when one coughs or sneezes on another person or on an object that is then handled by the other person, and by consumption such as in third world countries when feces seeps into water sources and infects a population.
How do the immune and respiratory systems work together?
Every life form needs oxygen. First of all, The respiratory system is connected with the cardiovascular system where blood gets oxygenated. As well all know, the blood is composed of several cells such as the red blood cells, white blood cells, platelets. The white blood cells are responsible for immune responses in the body. Without oxygen, all three would not function well and would make the person very ill and prone to infection.

How old was Edward Jenner when he went to college?
What starts an immune response?
when ever germs or viruses invade the body a white bloodcell eats it and travels to a lymph node wich house white blood cells. then all the white blood cells kill all the germs. in other words. the immunes system is triggered the second a white blood cell sees a germ or virus.
Should you be concerned with 2.8 white blood count?
A white blood cell count of 2.8 means that it is too low which is an abnormal low. This might be caused by a number of things with the most common one being pharmaceutical drugs. You should seek medical attention immediately.
Why is the skin a good defense mechanism for the immune system?
It acts like a shield, so micro organisms aren't able to pass through unless there is damage to the skin. (e.g. A cut.)
What does the thymus secrete to stimulate T lymphocytes?
Im afraid that your question is quite unclear.
If you are refering to how the thymus turns pre-T Cells into Naieve T-cells, this is not a process mediated by a secretion. Its a process called positive and negative selection (or central tollerance) mediated by surface molecules called MHCs present on thymic cells and Dendritic Cells, which eliminates those cells that either do not react with these MHCs or react too strongly. I hope this answers your question.............
What virus attacks the nervous system?
Poliomyelitis can enter the central nervous system and destroy motor neurons that can cause paralysis and muscle weakness/atrophy. Spinal polio is the most common form. Poliomyelitis is caused by poliovirus and used to be a dreadful disease in the 20th century. Now with better vaccines, the number of polio incidents have gone down.
They can enter the body in various ways. Mouth, nose, skin, ear, eyes, etc. Any entry way for bacteria is an entry way for disease- causing agents. Hand contact with someone who has those agents can cause one to
Once contact occurs, disease-causing agents, such as viruses and bacteria, may enter a person through breaks in the skin, or they may be inhaled or swallowed. Others may enter the body through the moist linings of the eyes, ears, nose, mouth, or other body openings.

How do you pathogens enter in the body of a healthy person?
Mainly by eating a source of good and nutrient foods,water,a good lifestyle meaning go to a gym so fat or cholesterol does not build up
Absolutely any drug is psychologically addictive. There are reports of individuals becoming psychologically addicted to drugs that have no capacity for addiction otherwise. With regards to physical addiction, the number of drugs is too large to count. Researching individual drugs is a good idea to find out more. Diamorphine (heroin) and benzoylmethyl ecgonine (cocaine) are two well known examples of addictive illegal drugs.
How the body encounter a foreign body?
A response of the body to an invasion of foreign substances is inflammation. The immune system will also produce more white blood cells and send them to the site of the infection.
What does it mean to have antibodies in your blood?
The antibody to an infectious disease is the RNA strand formed by an individual to destroy the bacteria or virus.
Which type of leukocyte contains heparin and anticoagulant?
Basophil is the type of leukocyte that contains heparin and is an anticoagulant. The type of leukocytes that become macrophages in the tissues are monocytes.
The seven types of leukocytes are: neutrophils, eosinophils, basophils, monocytes, macrophages, dendritic cells, and lymphocytes. Neutrophils, basophils, esinophils, monocytes and lymphocytes are the five most commonly thought of.
Do lymphocytes have a membrane?
All cells have a membrane that distinguishes their internal contents from the surrounding fluid or tissue. Remember, smaller entities such as virus or prions are not cells, but rather just protein complexes.
What Are workers needed to wrap around harmful bacteria to produce anti-bodies to combat diseases?
white blood cells
A low number of monocytes in the blood (monocytopenia) can occur in response to the release of toxins into the blood by certain types of bacteria (endotoxemia), as well as in people receiving chemotherapy or corticosteroids.
