Activation: (in biology) to turn on something like a gene or a chemical reaction.
asthma: A disease that affects the airways, the tubes through which animals breathe. Asthma blocks the airways through swelling, excessive mucus production, or narrowing of the tubes. As a result, the body expands to draw in air but loses the ability to exhale properly. The most common cause of asthma is allergies. Asthma is a chronic disease that is a leading cause of hospitalization and a major reason children miss school.

cell: (biology) The smallest structural and functional unit of an organism. Usually too small to be seen with the naked eye and composed of a watery fluid surrounded by a membrane or wall. Animals are composed of thousands to trillions of cells, depending on their size. Most organisms, such as yeasts, molds, bacteria, and some algae, are composed of only a single cell.
Chemicals: A substance formed by two or more atoms combining in a certain ratio and structure. For example, water is a chemical formed by two hydrogen atoms combining with one oxygen atom. Its chemical formula is H.2O. Chemical can also be used as an adjective to describe the properties of substances that result from various reactions between different compounds.
COVID-19SARS-CoV-2: The name given to the disease that caused a major global pandemic in 2020. It is caused by a novel coronavirus that first emerged in 2019 and is known as SARS-CoV-2. Symptoms include pneumonia, difficulty breathing, fatigue that limits the ability to walk more than a few steps, fever, headache, low blood oxygen levels, blood clots, and brain “fog.”
DiabetesThe disease is when the body produces too little of the hormone insulin (type 1 diabetes) or has too much insulin but ignores its presence (type 2 diabetes).
diet: (n.) The food and liquids that an animal ingests to provide the nutrients it needs to grow and stay healthy. This can also be a particular feeding plan. (v.) To adopt a particular feeding plan. People may adopt particular feeding plans for religious or ethical reasons, to deal with food allergies, or to control illnesses such as high blood pressure or diabetes. They may also adopt plans to lose weight, which can be unhealthy if not done under the guidance of a medical professional such as a doctor or registered dietitian.
Field: Field of study. Example: Her field of research is biology..
germ: Single-celled microorganisms such as bacteria, fungi, and virus particles. Some bacteria cause disease. Others promote the health of more complex organisms, such as birds and mammals. However, the health effects of most bacteria are still unknown.
Intestine: An informal term referring to the digestive tract, specifically the intestines.
hormone: (zoology and medicine) Chemicals made by glands and carried in the bloodstream to other parts of the body. Hormones control many important bodily activities, including growth. Hormones work by causing or controlling chemical reactions in the body. (botany) Chemicals that act as signaling compounds that tell plant cells when and how to grow or when to age and die.
Immune system: A collection of cells and their responses that help the body fight infections and deal with foreign substances that may cause allergies.
infection: (adjective) Infectious) A disease that spreads from one organism to another, usually caused by some kind of microorganism.
inflammation: (verb to inflame) The body's response to cell damage or obesity, often characterized by swelling, redness, heat, and pain. It is also the underlying cause of the onset or worsening of many diseases, especially heart disease and diabetes.
iron: A metallic element common in minerals in the Earth's crust and hot core. It is also found in space dust and many meteorites.
link: A connection between two people or things.
mechanism: The step or process by which something happens or “functions.” It might be the spring that makes something jump from one hole to another. It might be the contraction of the heart muscle that pumps blood throughout the body. It might be the friction that slows down a car as it coasts. To understand how something works, researchers often look for the mechanisms behind actions and reactions.
Mental Health: A term describing emotional, psychological and social well-being. It refers to how a person behaves with themselves and how they interact with others. It also includes how they make choices, handle stress and deal with fear and anxiety. Poor mental health can be caused by illness or reflect a short-term reaction to life's challenges. It can occur in people of all ages, from infants to the elderly.
Microorganisms: Short for microorganisms. Organisms that are too small to be seen with the naked eye, including many organisms such as bacteria, some fungi, and amoebas. Most are made up of a single cell.
Microbiome: A scientific term used to refer to all microorganisms (bacteria, viruses, fungi, etc.) that live permanently inside humans and other animals.
Microbiota: The microorganisms that live in a particular place or geological period. Scientists call the totality of microorganisms in humans and other animals the microbiome.
NutrientsThe vitamins, minerals, fats, carbohydrates, or proteins that plants, animals, and other living organisms need in food to survive.
nutrition: (adjective: nutritious) The healthy components (nutrients) of food, such as proteins, fats, vitamins, and minerals, that the body uses for growth and energy in its processes. Scientists who work in this field are known as nutritionists.
Red blood cells: Pigmented red by hemoglobin, these cells carry oxygen from the lungs to all the tissues of the body. Red blood cells are too small to be seen with the naked eye.
Social: (adjective) relating to a group of people. A term used to refer to animals (or people) that prefer to be in groups. (noun) A gathering of people, as in a club or other organization, for the purpose of enjoying each other's company.

Psychological stress can be positive or negative. (physics) Pressure or tension on a substance.
Symptoms: A physical or mental indicator commonly regarded as characteristic of illness. A single symptom, especially a common symptom such as fever or pain, may be a sign of many different kinds of injury or illness.
system: A network of parts working together to accomplish some function. For example, blood, blood vessels, and the heart are the main components of the human body's circulatory system. Similarly, trains, platforms, tracks, road signals, and overpasses are some of the potential components of a country's rail system. System can also apply to a process or idea that is part of some way or ordered series of steps to complete a task.
Type 2 diabetes: (See also diabetes) A ​​disease caused by the inability to effectively use insulin, the hormone that helps the body process and use sugar. If diabetes is not controlled, people face the risk of heart disease, coma, or death.
virus: A small infectious particle consisting of genetic material (RNA or DNA) surrounded by protein. A virus can only reproduce by injecting its genetic material into the cells of an organism. Scientists often refer to viruses as either living or dead, but in fact many scientists argue that there are no truly living viruses. Viruses do not eat like animals or make their own food like plants; they must hijack the cellular machinery of a living cell in order to survive.
vitaminAny of a group of chemicals that are essential for normal growth and nutrition and are required in small amounts from the diet because the body cannot produce them or cannot easily produce them in sufficient amounts to maintain health.
