MicrobiotaMicrobiota are the range of microorganisms that may be commensal, mutualistic, or pathogenic found in and on all multicellular organisms, including plants. Microbiota include bacteria, archaea, protists, fungi, and viruses, and have been found to be crucial for immunologic, hormonal, and metabolic homeostasis of their host. The term microbiome describes either the collective genomes of the microbes that reside in an ecological niche or else the microbes themselves.
Ocular surface microbiomeThe ocular surface microbiome or ocular microbiome refers to the microbiota, including bacteria and fungi, that live on the eye, mainly the conjunctiva and cornea. Flora found on the eyelid and eyelashes are considered to be part of the skin microbiome, although some bacteria are shared across regions.
Human skinThe human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermaltissue guarding muscles, bones, ligaments and internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear hairless. There are two general types of skin: hairy and glabrous skin (hairless).

LungPrimary organ of the respiratory systemThe lungs are the primary organs of the respiratory system in many animals, including humans. In mammals and most other tetrapods, two lungs are located near the backbone on either side of the heart. Their function in the respiratory system is to extract oxygen from the atmosphere and transfer it into the bloodstream, and to release carbon dioxide from the bloodstream into the atmosphere, in a process of gas exchange.
UterusThe uterus (from Latin uterus, pl.: uteri or uteruses) or womb () is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment. (The term uterus is also applied to analogous structures in some non-mammalian animals.)
SalivaSaliva (commonly referred to as spit, drool or slobber) is an extracellular fluid produced and secreted by salivary glands in the mouth. In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lingual lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Ovarian follicleAn ovarian follicle is the reproductive unit in the ovary. The first follicles to form are the primordial follicles consisting of a primary oocyte surrounded by a layer of pre-granulosa cells known as follicular cells. The follicular cells are somatic cells that interact with and support the oocyte during its development involving much cross-talk. Part of this support is the release of fluid to the enclosed oocyte.
Mammary glandA mammary gland is an exocrine gland that produces milk in mammals, including humans. Mammals get their name from the Latin word mamma, "breast". The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the of other animals (for example, dogs, cats, rabbits and pigs) to feed young offspring.Oral mucosaThe oral mucosa is the mucous membrane lining the inside of the mouth. It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. The oral cavity has sometimes been described as a mirror that reflects the health of the individual.
Gastrointestinal tractThe gastrointestinal tract (also called the GI tract, digestive tract, gut and the alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus. The tract is one of the largest of the body's systems. The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.
SemenSemen, also known as seminal fluid, is a bodily fluid that contains spermatozoa from the male gonads of animals. In humans and placental mammals, seminal fluid is ejaculated through the penis via the urethra.
