Useful Medicinal Compounds Derived from Animals

The immune system is made up of trillions of specialised cells (white blood cells) that detect and destroy pathogens or their toxins. Some white blood cells, which are

It has targeted cells that work to kill and defend any pathogen or impurity that enters one’s body. In the case of cancers, a person’s cells grow abnormally forming a tumor. Unlike normal cells, cancer cells lose the ability to undergo apoptosis, cell death. Thus, one’s body harvests a tumor that most likely has a chance to spread and become deadly. Luckily, the biotech industry concocted innovative research that called for a new method of cancer treatment. Immunotherapy is designed to program one’s immune system to destroy and fight off the cancer. Originally, it has been mainly used for allergies. Dosages of medication or vaccinations are given to a patient to ensure that the immune system will not overreact to certain types of foreign substances. The therapy requires a drug that delivers an anticancer immune cell, specifically designed to attach on to the specific antigen that the tumor contains. According to scientist, immunotherapy gives patients “long term protection with reduced side effects against the cancer” (McGinley). The purpose of this treatment is to strengthen the immune system and specifically targets cancerous cells. Due to scientific research and the use of biotechnological methods, immunotherapy is able to prevent the threat of killing cells necessary to one’s body. Providing patients with a treatment that does not take a toll on their bodies, nor threaten to kill healthy cells is one relief the person

Human beings are born with immunity as well as they acquire it from the environment they grow in. Human innate immunity is assigned the task to hinder the harmful substances from entering the body. These immunity barriers develop a defense line. The innate immunity includes cough, tear enzymes, mucus, skin and the stomach acid. Hence, the role of innate immune system is to stop harmful materials from entering our body. In case the innate immunity is insufficient to fight, there is acquired immunity that fights harmful substances by getting exposed to various antigens. The acquired immunity is developed against specific antigen. Its role is to fight

In the biology Immunology field, immunity is defined as the balanced state of a living organism for instance, the human body having sufficient biological defenses to combat infection, illness, or other unwanted biological incursion, while having acceptable tolerance to avoid contamination and allergies (Sompayrac, 2012, p.5). The immune system is a group of cells, nerves, and molecules that defend the body from many pathogenic microorganisms and contaminants in the environment.

Humans such as us alike cannot live in a world without a highly effective defense system that helps us to resist against infections and toxins caused by microorganisms. The immune system is a complex network of consorting cells, tissues and organs that defend the body from pathogens and other harmful substances. This essential complex consists of two subsections : the innate immune system and the adaptive immune system.

The immune system is consisted of cells and tissues throughout the whole body. They work together to defend your body from any types of invasion and infections. Problems with the immune system can cause the immune system to mistaken the healthy body cells as invaders and will repeatedly attack the cells; this is known as an autoimmune disease. An example of this disease is the Hashimoto’s thyroiditis, where the immune systems mistakenly recognizes the thyroid cells as invaders and attack the thyroid.

The Immune system is the bodies defense mechanism. Through immune responses, the immune system attacks organisms and substances that can cause diseases. The immune system is made up of cells, tissues, and organs. The most important cell is the white blood cell. The white blood cells are the cells that seek and destroy disease causing bacteria.

5.1 Antigens provide the body with immunity. The immune system then creates its own way of defending the body against unknown antigens. This kind of defense is known as the immune response and mostly based from the production of specific protein molecules which are named antibodies, which eliminate unknown substances. The immune response which is more effective are created by responding to an organism which is alive. Once the antigen has been put into the body it will provide the body with immunity for a long time if not forever. (The Immunisation Advisory Centre [TIAC], 2016, para. 5)

Immunotherapy means using the immune system as a way to help fight cancer. The American Cancer Society defines immunotherapy as "based on the body 's natural defense system, which protects us against a variety of diseases. . . . [and] also works to aid our recovery from many illnesses." Immunotherapy has been shown to make other forms of treatment more effective and

In 2014 767,622 animals were used for medical research. Without these animals to test on we would have had to test on other human beings. Who would you rather test on, a rat, or a loved one? Medical animal testing is needed to keep moving forward in the medical fields and to keep our society strong.

The immune system, which is made up of special cells, proteins, tissues, and organs, defends people against germs and microorganisms every day. In most cases, the immune system does a great job of keeping people healthy and preventing infections. But sometimes problems with the immune system can lead

There is only one particular antibody to kill pathogen causing the sickness or infection. Similar to how we have learned in science class, that each enzyme can only digest one type of substrate. For instance, lactase can only digests lactose because each substrate requires a specific active site. There is no specific antibody to fight cancer, since the body does not recognize cancer as an invader or a foreign substance, as the body does for other pathogens, since the cancer cells are just mutations of healthy cells already in our immune system.

The genetic variation within a number of many individuals causes natural selection to occur. With this natural selection we are susceptible to the chance of risk that can ultimately cause our immune systems to alter antagonist genes, a structure that changes the way our body normally operates. This variation as individuals evolve over time changes the way our immune system reacts and defends against diseases (Genetic Control of Immune Response and Susceptibility to Infectious Diseases, 2013).

The immune system consists of a defense system that guards the body against invasion from infections and other diseases. Normally, a healthy person's immune system has the capability to differentiate between its own cells and cells that represent threats to the health of the body. (Craft and Kanter, 2002). Autoimmune disease refers to a broad range of over 80 acute, long-lasting diseases that affect nearly every organ in the body. (Wrong Diagnosis.com, 2000).

When the pathogen replicates different components of immune system evolves to protect against various types of pathogens. However infection of an organism does not necessarily shows diseases, disease are only present when the bolus of infection, in terms of when immunity is comprised. All components of
