External nares ( Nostrils) are the openings formed by the external nose that open into the nasal cavity.
Humans have the capacity to change their ways, often driven by necessity, innovation, or social pressures. Historical trends show that significant challenges, such as climate change or public health crises, can motivate shifts in behavior and values. However, the extent and speed of change can vary widely among individuals and cultures. Ultimately, whether humans will change depends on a combination of awareness, willingness, and external factors.

Internal systems of the human body refer to structures and processes that occur within the body, such as the circulatory, respiratory, and digestive systems, which work to maintain homeostasis and support life. External systems, on the other hand, involve interactions between the body and the outside environment, including the integumentary system (skin, hair, nails) and sensory organs that help in perceiving external stimuli. While internal systems focus on internal functions crucial for survival, external systems facilitate interaction and protection from the environment. Together, they ensure the overall health and functionality of the organism.
Latent functions are unintended, while manifest functions are intended.
Both the internal as the external anal sphincter.
nares are nostrils. the maxillary bones form the lateral margins of external nares/nostrils
The paired nares are another term for the nasal openings on a pig. These nares take in air to the sinuses.
External Nares
external nares
Air moves in and out of the external nares, also known as the nostrils. During inhalation, air enters the respiratory system through the external nares, where it is filtered, humidified, and warmed before reaching the lungs. During exhalation, air exits the respiratory system through the same external nares.
External nares are openings in the nostrils that allow air to enter the respiratory system during breathing. They also help filter and humidify the air before it reaches the lungs. Additionally, external nares play a role in the olfaction process by allowing smell molecules to enter the nasal cavity for detection.

The nostrils or nasal openings, -- the anterior nares being the external or proper nostrils, and the posterior nares, the openings of the nasal cavities into the mouth or pharynx.
external nares
Nares are the external openings of the nose (human, animal, or reptile). These are also known as nostrils or the nasal passages.
For the most part, frogs breathe air through the mouth, and utilize internal nares when doing so outside of the water. In the water, they can put just enough of the external nares above water, but this is more important to get rid of carbon dioxide, as frogs can diffuse oxygen from the water through their skin.
