Körperöffnungen

Körperöffnungen are anatomical features on the external surface of an organism that lead to internal cavities or passages. In humans and many other animals, these openings serve various biological functions. The most commonly recognized body openings include the mouth, nostrils, and anus. The mouth is crucial for ingestion of food and water, as well as vocalization. The nostrils facilitate respiration and olfaction. The anus is the terminal opening of the digestive tract, through which waste material is expelled.

Other significant body openings include the external auditory canals, which are part of the auditory system and lead to the eardrum. The female reproductive tract has the vaginal opening, and the male reproductive tract has the urethral opening, which also serves for urination. In some species, specialized openings exist for other purposes, such as glands or sensory organs. The integrity and proper functioning of these openings are vital for health and survival, as they are potential entry points for pathogens and can be affected by various physiological processes and medical conditions.
