Border guards are the element of a security force include the mission of protecting against internal and external threats.
Host defenses that protect against infection include natural barriers. Such barriers are skin, or mucous as an example.
it is niether because an external is a conflict with others and an internal is a conflict with yourself.
Immune oil can help boost your body's defenses against illness and infection by containing essential oils that have antimicrobial properties. These oils can help strengthen the immune system and fight off harmful pathogens, potentially reducing the risk of getting sick.
Skin, mucous membranes, sloughing of dead skin, tears, sweat, normal microbial flora of skin.
An internal skeleton provides flexible support for movement and growth, allows for larger body sizes, and protects internal organs. In contrast, an external skeleton provides better protection against predation and dehydration and can serve as a barrier against pathogens.
I would say to cause pain and be about sure to cause to be dead.(No defenses against infection, as skin does, among some stuff.)
some female dogs that are not spayed may develop Pyometra which is an infection of the uterus. There is 'internal' Pyometra and 'external' Pyometra. With external, the dog will have a smelly discharge (typically after they have been in season). With internal there won't be any discharge and is therefore harder to detect. The condition is very serious and you are racing against time to save the life of your dog. Treatment requires removal of the uterus.
The politic of today Romania (internal and external) is very bad and against the Romanian people.
All living things have defenses, yes.
Yes, T-cells are considered internal defenses as they are a crucial component of the adaptive immune system. They originate from bone marrow and mature in the thymus, where they develop the ability to recognize and respond to specific pathogens. T-cells play a vital role in identifying and eliminating infected or cancerous cells, thus contributing to the body's internal defense mechanisms against diseases.
Physical defenses are considered the body's first line of defense against disease because they provide immediate protection against pathogens. These barriers, such as the skin, mucous membranes, and cilia, prevent the entry of harmful microorganisms into the body. They act as a physical shield, blocking pathogens and reducing the likelihood of infection. Additionally, these defenses are always present and ready to respond, making them crucial for maintaining overall health.
