The Immune and Endocrine Systems
What do they do?
The Endocrine and Immune systems are 2 completely separate and different body systems. The immune system is the body system in charge of fighting substances and bacteria that invade the body and cause disease. Organs,tissues,and cells work together to protect the body.It keeps our body stable and allows us to get better after being attacked by an illness. The Endocrine System is the body system that creates and is in charge of the hormones, sexual reproduction, and reproductive parts, such as gametes. The repopulation of the human species depends on this system. the glands in this body system regulate growth and metabolism, as wells as hormones.
Words to be familiar with
- Pathogen- a virus or microorganism that can cause a disease to the host
- Active Immunity- resistance in of its own antibodies in response to an antigen
- Passive Immunity- short term resistance resulting from the introduction of antibodies from another organism
- Antigen- substance that causes an immune response
- Antibody- blood protein made in response to an antigen
Why antibiotics are effective against bacteria but not against viruses
Antibiotics do not work on viruses because viruses are not living, while bacteria is. A virus can be a piece of DNA or RNA and is injected into living cells. These cells reproduce with the virus as the DNA or RNA, spreading the growth of the virus. Antibiotics work by disrupting the structure, metabolism, and replication of a "living microorganism"/bacteria which is considered living. With the lack of a metabolism, viruses cannot be destroyed with antibiotics.
Disorder and HIV/ AIDs ,treating,statistics)
There can still be illnesses and disorders the immune system can't fight off, too. A very common disorder that can be a reaction to various thins are allergies. Allergies are responses to substances, foods, or medicines. Since the immune system fights against germs, your body is just sensitive to those certain substances. Some symptoms include sweating, itching rash, and swelling. They can be treated by avoiding contact or medicine, depending on the substance. Affecting for than 50 million people in the united states, allergies can be very common. Another disorder that an happen in the immune system is a virus called HIV, which can lead to a condition called AIDS. HIV infects humans and the immune system, not allowing the body to function properly. AIDS is a condition that appears when HIV has excessively damaged the immune system. Some of the symptoms of both include vomiting, infections, and pain. While there is no cure or way to completely fight off HIV, nevertheless AIDS, it can be controlled with a restricted life and medication. Both HIV and AIDS are found in about 30-40 million people around the world.
homeostasis and explain its role in the endocrine system.
Homeostasis is the ability for your body to remain stable. When your body is introduced to a virus, rise in body temperature,or anything that changes stability, homeostasis allows your body to return back to its original stable form. In the endocrine system, homeostasis is very important because this body system is in charge of regulating. Homeostasis allows the system to regulate the metabolism, glucose levels, hormones,etc. We would never be able to maintain a stable hormonal stage or regular glucose level if your ate skittles. Homeostasis is the main contributor to this system and allows it to regulate everything back to normal.
Negative feedback mechanism
Negative Feedback Mechanism is a type of feedback, comparing to positive feedback. It is when the body realizes it is not stable and does everything possible to fight against the resistance and return to a normal stage. In contrast to positive feedback, the body does not keep going with the change, it fights against it and tries to go away from it by doing the opposite. for example, when your running or doing any type of exercising, your body temperature rises. Because of negative feedback, the body beings to sweat to cool down the body. The body temperature then cools down and drops.
Type I Diabetes and Type II Diabetes
Diabetes is the result of too much glucose in the blood/body. This is a cause of irregular insulin production,the body does not respond to insulin correctly, or both. Patients with diabetes have symptoms including frequent urination, hunger and thirst. Found in 382 million people around the world, This disorder can be classified into 2 types: Type 1 and Type 2. Type 1 Diabetes is when the body makes no insulin and require patients o take insulin injections for the rest of their life, have regular blood tests, and follow a special diet. Type 2 Diabetes is when the body does not make enough insulin or the cells do not react to it. Patients must live a healthy life and take medication.
