describe how these parts work together in an organism
Organ systems are the level of organization made up of organs working together to perform a function. Examples are the digestive and reproductive systems.
Immunity is a function rather than a set of anatomical organs that we find in other systems.
Cardiovascular and neurological
similar tissues working together to preform a function An organ is an aggregate/collection of tissues that are adapted to perform a specific function (sometimes more than one) vital to sustaining life. In humans, organs are grouped together to form organ systems. Examples of organs are the heart, lungs, liver, kidneys. Examples of organ systems are the circulatory system (heart, blood vessels) and respiratory system (lungs, bronchioles, trachea)
Our immune systems are designed to keep track of the various infections that can be caused by pathogens once they encounter them. This helps to increase our immunity as this information helps the bodies immune system to fortify itself against further attacks by the same pathogen. If immunity is increased by means other than acquiring the disease, then it is known as passive immunity. e.g. Vaccination( in this weak pathogens are injected in the body and this helps the body's immune system to remember and then identify it to fortify the body for any future attacks by that pathogen)

Tonsils are the immune systems first-line of defense against inhaled pathogens. They produce T-cells, a type of white blood cell that aids in immunity. The spleen helps with immunity by purifying the blood and helps the immune system recognize and attack foreign antibodies.
oh ok
Because our bodies have evolved to defend ourselves from these pathogens. We have an "immune system".
Diffusion take place in these systems.
Vaccines help the immunity systems to stay strong from particular diseases. In the immunity system carries microorganism that recognize the agents as foreign, destroy it and remembers it.
There are several good examples of incontrovertible systems. A good examples of incontrovertible systems should be camera systems, or recorded systems.
The aliens in War of the Worlds are ultimately killed by Earth's bacteria and viruses, to which they have no immunity. Their biological systems cannot withstand these pathogens, leading to their downfall.
Charolais have the same immunity to diseases as many other beef cattle have. It all depends on what their immune systems are exposed to and what they are not.

Tonsils are part of the lymphatic system. They are located in the back of the throat. They function to guard against inhaled and ingested pathogens. They have deep pits that catch bacteria and food debris. This is then circulated by the circulatory system and eaten by macrophages. (very big cells) People often have them removed because they become infected and cause problems.
