Examples of cavity in the following topics:

  • Classification and Identification of Helminths

    • The classification and identification of helminths are dependent on numerous factors including body shape, body cavity, body covering, digestive tubing, sex and type of attachment organs.
    • They lack a body cavity and have a tegument body covering.
    • They also lack a body cavity and have a tegument for body covering.
    • Nematodes are characterized by a cylindrical body shape and do indeed have a body cavity.

  • Tooth and Gum Infections

    • Dental caries, also known as tooth decay or cavity, is a bacterial infection that causes demineralization and destruction of the hard tissues (enamel, dentin, and cementum).
    • If demineralization exceeds saliva and other remineralization factors, such as from calcium and fluoridated toothpastes, these hard tissues progressively break down, producing dental caries (cavities, holes in the teeth).
    • The bacteria most responsible for dental cavities are the mutans streptococci, most prominently Streptococcus mutans and Streptococcus sobrinus, and lactobacilli.
    • The oral cavity of the newborn baby does not contain bacteria but rapidly becomes colonized with bacteria such as Streptococcus salivarius.
    • Spirochetes and fusi-form bacilli live as normal flora in the mouth, but the bacteria can cause infection and diseases to the oral cavity.

  • Bacteroides and Flavobacterium

    • The ability of the bacteroides to function in an anaerobic environment allow them to reside in the abdominal cavity in aerotolerant conditions.

  • Bacteroidetes and Chlorobi

    • The Porphyromonas class is characterized by their presence in the oral cavity of humans.

  • Biosynthesis of Tetrapyrroles

    • A porphyrin without a metal ion in its cavity is a free base.

  • Colonization and Growth

    • Entrance to the host generally occurs through the mucosa in orifices like the oral cavity, nose, eyes, genitalia, anus, or open wounds.

  • General Morphology

    • Helical - These viruses are composed of a single type of capsomer stacked around a central axis to form a helical structure, which may have a central cavity, or hollow tube.

  • Diphtheria

    • It is characterized by sore throat, low fever, and an adherent membrane (a pseudomembrane) on the tonsils, pharynx, and/or nasal cavity.

  • Bacterial Infections of the Heart

    • Bacteremia caused by dental procedures (in most cases due to streptococci viridans, which reside in oral cavity), such as a cleaning or extraction of a tooth and from procedures involving the gastrointestinal or urinary tract can cause bacterial endocarditis.

  • Hydatid Disease

    • Cysts are typically found in the liver and in the thorax or abdominal cavity.
