Immune System

The main groups of pathogenic organisms causing disease in the UK include bacteria (e.g. Staphylococcus aureus), viruses (e.g. influenza virus), fungi (e.g. Candida species), and parasites (e.g. Giardia lamblia). These organisms can cause a range of illnesses from common infections to more serious diseases.

There are about a thousand times as many red blood cells as white cells.

Consider that the red blood cells (or erythrocytes) in a mm3 (or microliter) of blood number about five million in an average man (a few less in a woman). The white blood cells (or leukocytes) number only 5-6 thousand per mm3 so the ratio is about a thousand fold.

A true pathogen is a microorganism that can cause disease in healthy individuals with normal immune systems. Examples include certain types of bacteria, viruses, fungi, and parasites that are capable of causing illness without the need for any predisposing conditions.

Cystic Fibrosis is caused by a genetic mutation in the CFTR gene. This mutation leads to the production of thick, sticky mucus in the lungs and other organs. It is not caused by a specific pathogen, but individuals with Cystic Fibrosis are more susceptible to respiratory infections.

When you get a splinter or scratch, the immune system detects the injury and sends immune cells like neutrophils and macrophages to remove any debris or pathogens that may have entered. These cells also help to initiate the inflammatory response, which is important for healing and protecting the damaged tissue from infection.

Leukocytes, also known as white blood cells, are responsible for protecting the body against infections and foreign invaders. They play a crucial role in the immune system by identifying and destroying pathogens such as bacteria, viruses, and other harmful substances. Leukocytes are produced in the bone marrow and circulate throughout the body in the blood.

The classification of prokaryotic life is subject to a lot of change and in the past has been a very controversial subject.

For years the main kingdoms were considered to be Prokaryotes, Animals, Plants and Fungi but this has subsequently proven to be too broad.

The Prokaryotic kingdom was initially split into two new kingdoms:

Eubacteria
and
archaebacteria

Recent RNA studies of these kingdoms have revealed that this classification is too simplified too and that despite being single celled organisms with no true organelles the Eubacteria differ sufficiently within their own kingdom to be split into further kingdoms.

This means that they can be considered to be as different from one another as plants are from animals.

The Eubacteria classification is therefore one of a Superkingdom. The two kingdoms within it contain, for the sake of simplicity, the gram negative and gram positive bacteria (those who don't take up the gram stain and those who do).

The first of these are called protobacteria and contain E. Coli and other similar bacteria that are human pathogens. However other human pathogens such as Staphylococcus are in the gram positive kingdom.

Many scientists have been trying to discover if any archaebacteria can be human pathogens but at the time of writing we have been unable to find evidence of any.

The superkingdom that contains bacterial pathogens is therefore eubacteria and both kingdoms within it contain pathogens.

A leukocyte esterase is an enzyme found in the urine that indicates the presence of white blood cells, specifically leukocytes. It is often used as a marker for urinary tract infections. High levels of leukocyte esterase can suggest inflammation or infection in the urinary tract.

Lymphocytes can live for weeks to years, depending on the specific type. B cells can live for a few days to several weeks, while memory T cells can persist for a lifetime. Factors such as the type of lymphocyte, presence of infections, and overall health can influence their lifespan.

The Endocrine system is responsible for slower metabolic changes over seconds, minutes, hours, or even years. The Nervous system is responsible for analyzing sensory information and providing an immediate, short term metabolic change. The Exocrine system is responsible for outer layer adaptation. Such as a metabolic response of secretions like sweat, or milk produced from mammary glands.

I just thought to give a simple answer with my little knowledge of anatomy and physiology.Blood should have that much of warmth to keep all live parts in a constant manner. Like the water of this earth blood flows everywhere and should be so. Respiration is the result of breath not just air.The wave of breaths is the result of a big pressure burst occurred at birth.so all the systems there you see are the formations of energy variants of each level which contribute to each other to keep the energy transformation at a constant rate.

Yes, white blood cells produce antibodies in response to foreign substances like viruses or bacteria. These antibodies can recognize and neutralize specific pathogens, helping the immune system become immune to certain diseases by identifying and attacking them upon future exposure.

A form of acquired immunity resulting from antibodies that are transmitted naturally through the placenta to a fetus or through the colostrum to an infant or artificially by injection of antiserum for treatment or prophylaxis. Passive immunity is not permanent and does not last as long as active immunity.

M protein is a surface protein on Streptococcus pyogenes that can prevent phagocytes from recognizing and engulfing the bacteria. This evasion tactic allows the bacteria to evade the host immune response and persist in the body.

An unexpected antibody in human blood means that a person does not have the antigen required to make a certain antibody because it is foreign to them. Unexpected antibodies are usually alloantibodies.

The muscular sac that grinds and churns food into liquid chime is called the gizzard. This organ is extremely important during digestion.

B cell 'education' is another way for describing the selection of the best B cells to deal with pathogens.

Both the host body and pathogens have molecular markers of identity. Pathogens display antigens that are classed as 'non-self' and cells of the body/self display major histone compatibility (MHC) molecules.

Deciding the difference between these two 'identity advertising' molecules is difficult. This is because there is no absolute difference between them; often their molecular structures are similar.

As such B cells must learn the correct threshold activation for an immune response.

Should the B cell over react to self/ MHC complexes then we have a case of autoimmunity. If the B cell over reacts to foreign bodies we have allergy.

How then do they become educated?

Dendritic cells intake extracellular antigens (foreign body molecular markers) and display them on their cell surface to advertise to the adaptive immune cells - specifically: T cells.

This activates the production of antigen-specific T cells which in turn activates the development of complimentary antigen-specific B cells.

Through this manner T cells and B cells are educated about which foreign bodies they should react to.

To prevent T and B cell over reaction to the self, the Thymus (located in between the lungs) destroys T cells that bind with host MHC complexes and lead to autoimmunity. This prevents these T cells from remaining in the body, stimulating complementary autoimmune B cells that could harm the body from the inside.

Disorders demonstrating the importance of education are numerous. Severe Combined Immuno Deficiency Syndrome describes a congenital disorder (one that originates in the germline) that results in the compromised development of the thymus. This means a lack of T cells develop and so the adaptive immune system is compromised. HIV targets helper T cells with CD4+ receptors that are involved in the proliferation of B cells needed for immune response.

Hope this helps

Micro Means extremely small, we can only see micro-organisms in a microscope, Every Living creature has micro organisms on and in there body! even humans possess micro-organisms, such as bacteria, fungi and a virus, we all have these.

The reproductive system of a monkey is similar to that of other mammals. It includes organs such as the testes in males and the ovaries in females, as well as structures like the penis and vagina. Monkeys reproduce sexually through mating, leading to the fertilization of eggs by sperm.

Activated Tc cells can differentiate into both cytotoxic T-lymphocytes, which directly kill infected or cancerous cells, and memory T cells, which are long-lived and provide a rapid response upon re-exposure to the same pathogen. This differentiation allows the immune system to mount a faster and more efficient response upon encountering the same threat in the future.

Distilled water is typically free of microorganisms, including bacteria, due to the purification process of distillation, which involves boiling water and collecting the steam. However, contaminants can potentially enter distilled water through improper storage or handling post-distillation.

Probiotics probably wouldn't cause vomiting since they are beneficial bacterial flora that inhabit the healthy gut. These normal flora help a variety of functions in the body and there is even research that they may help in preventing some types of cancer.

So, I doubt the probiotics caused your vomiting. If it happens again with the same one, I would definitely not use that brand probiotic again. However, you need to be careful when buying a probiotic. I would recommend one Made in America. The best one I've seen in doing some research on the web is called Fundamental Probiotic.

Q: Do cells function similarly in all living organism?

A: Yes, all cells function in all living organism by the smallest functional and structural unit in all living organisms; usually consists of a nucleus, cytoplasm, and a membrane.
