Respiratory System
Thoracic and Abdominal Cavity
What does the diaphragm separate?
Blood coming from the cells release CO2; Blood going to cells receives O2
What takes place through the tissues of the alveoli?
Emphysema/Chronic Bronchitis
a condition resulted by the breakdown of the alveoli or cigarette smoking
Diaphragm
a sheet of muscle which the lungs depends on for us to breathe; stretches across the inside of the body below the lungs
Surfactant
a substance that lines and keeps the alveoli open and prevents them from collapsing
bronchiole
a very tiny tube that dead ends in an alveolus within the lungs
Epiglottis
an elastic cartilage located at the root of the tongue that folds over the windpipe to prevent food from entering during swallowing
Asthma attack
caused when breathing unfiltered air through the mouth
C(H2O) + O2 => CO2 + H2O + energy for living
chemical formula for cellular respiration
Larynx (voice box)
contains the vocal cords; Adam's apple
Respiratory System
designed to reject solid and liquid material
Respiration
involves the exchange of two gases between your body and the enviroment
Internal or Cellular Respiration
is the actual use of oxygen by the cells of the body and the release of carbon dioxide in exchange
External Respiration
is the mechanical exhaling and inhaling that is needed to get the oxygen from the air and into the lungs
cilia
short filaments which wave in a coordinated fashion to move mucus
Bronchial tube
smaller branches of the bronchi within the lungs
Antigen
substance that stimulates the production of an antibody
Gas exchange
takes place by diffusion through the walls of the alveoli
Pharynx (throat)
the back part of the mouth and nasal cavity; where air passes through
Abdominal cavity
the cavity that lies between the thorax and the pelvis
Bronchi
the two tubes into which the trachea divide to go into each lung
Alveoli (Alveolus: singular)
tiny sacs within the lungs which increase the surface available for gas exchange; makes up most of the lung tissue
Inhalation and Exhalation
two steps in the process of breathing
Alveoli
where air entering from the lungs is terminated
Mucus
where inhaled debris sticks to before entering the lower reaches of the lungs; produced by glands at the airways of the lungs
Nose
where the air entering the lungs are filtered
