Question

Identify, break down, and define 10 medical terms relating to the circulatory or respiratory systems.

Answer 1

NoseIt - is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration. It also houses the nosehairs, which catch airborne particles and prevent them from reaching the lungs. Within and behind the nose there is the olfactory mucosa and the sinuses.

turbinate(or nasal concha)- is a long, narrow and curled bone shelf (shaped like an elongated sea-shell) which protrudes into the breathing passage of the nose. The turbinates divide the nasal airway into three groove-like air passages -and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible surface of cilia and climate controlling tissue.

Sinus- A sinus is a sack or cavity in any organ or tissue, or an abnormal cavity or passage caused by the destruction of tissue.

Paranasal- Paranasal sinuses are air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face The paranasal sinuses are joined to the nasal cavity via small orifices called ostia.

Pharynx-The section of the alimentary canal that extends from the mouth and nasal cavities to the larynx, where it becomes continuous with the esophagus.

Larynx- Voice box

Epiglottis- The thin elastic cartilaginous structure located at the root of the tongue

Trachea-A thin-walled, cartilaginous tube descending from the larynx to the bronchi and carrying air to the lungs. Also called windpipe.

Bronchi-The two main brances of the trachea, leading directly to the lugns.
Bronchiole-The fine, thing-walled, tubular extensions of a bronchus.
