Science 1.2 Flashcards
System that consists of passages that filter incoming air and transport it into the body, lungs, and to many microscopic air sacs where gasses are exchanged
Respiratory system
The entire process of exchanging gasses between the atmosphere of the body cells
Respiration
Microscopic air sac in a lung ; small cavity
Alveolus
Primary branch of the trachea; windpipe
Bronchus
Ridge of cartilage between the right and left bronchi
Carina
Flap-like structure that partially covers the opening into the larynx during swallowing
Epiglottis
Pigment in red blood cells
Hemoglobin
Nerve associated with the cervical plexuses that stimulates the muscle fibers of the diaphragm to contract
Phrenic nerve
Organs of the respiratory system
Nose
Nasal cavity
Sinuses
Parts of the respiratory system (20)
Frontal sinus Nasal cavity Hard palate & soft palate Nostril Oral cavity Larynx Bronchus Right and left lung Uvula Tongue Hyoid bone Trachea Nasal conchae Sphenoidal sinus Pharyngeal tonsil Nasopharynx Opening of auditory tube Epiglottis Esophagus
The main passage ways directly attached to the lungs
Bronchi
Small passages in the lungs connected to bronchi and alveoli
Bronchioles
The passage of fluid to an organ or a tissue
Perfusion
A membrane around the lungs and inside the chest cavity
Pleura
A fluid decreased by alveoli and found in the lungs to prevent the lungs from collapsing due to surface tension
Surfactant
