Vagina01:26

Vagina

36.7K
The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.0K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

9.9K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Bacterial Phylum Verrucomicrobiota01:26

Bacterial Phylum Verrucomicrobiota

595
The phylum Verrucomicrobiota comprises at least four characterized orders, with most species classified within the order Verrucomicrobiotales. Members of this phylum are either aerobic or facultatively aerobic, with the ability to ferment sugars. A notable exception is the genus Methylacidiphilum, which consists of aerobic methanotrophs. Additionally, some Verrucomicrobiota establish symbiotic relationships with protists. These bacteria are widely distributed across various environments,...

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

1.7K
The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

External Female Genitals01:15

External Female Genitals

36.8K
The vulva encompasses the external structures of the female reproductive system. At the forefront is the monpubis, a cushion of fatty tissue atop the pubic bone. Once puberty sets in, this area typically grows hair. Extending from just behind the mons pubis are the labia majora (labia = 'lips'; majora = 'larger'), which are larger skin fs olds coated with hair. Nestled within are the labia minora (labia = 'lips'; minora = 'smaller'), which are thinner, more...
