The only respiratory organ visible from the outside that receives air from the outside environment
Nose
Long flexible "air" tube reinforced by rings of cartilage
Trachea
What muscle contracts to expand the lungs for inhalation?
Diaphragm
What is another name for breathing?
Pulmonary Ventilation
The smallest branches of the respiratory tree
Bronchioles
The section of the pharynx located behind the oral cavity
Oropharynx
This lung has three lobes and rests on the liver
Right lung
Normal quiet breathing
Tidal volume
Oxygen is transported throughout the body via this protein
Hemoglobin
Vibrate with expelled air to create sound
Vocal cords
Covers the larynx and routes food to the esophagus
Epiglottis
Site of gas exchange in the lungs
Alveoli
This is mostly a passive process in which the diaphragm is relaxing
Gas exchange between the pulmonary blood (capillaries) and the alveoli
External Respiration
The trachea is lined with _______ _________ that helps to move foreign particles away from the lungs
Ciliated Mucosa
Contains olfactory receptors in the upper surface
Nasal Cavity
The thin double-layered serous membrane filled with pleural fluid that covers the lungs
Pulmonary Pleura
The amount of air an individual can inhale deeply and then exhale fully
Vital Capacity
Carbon dioxide is converted into bicarbonate ion and travels through the body in the
Plasma
The amount of air that can be forcefully exhaled beyond tidal volume expiration
Expiratory reserve volume
Largest hyaline cartilage of the larnyx that protrudes as the Adam's apple
Gas passes through the respiratory membrane through this process
Simple diffusion
Increased rate of respiration is controlled by ____________ in response to ______________.
Medulla oblongata
Increased CO2 Levels
The four events of respiration in order
1. Pulmonary ventilation
2. External respiration
3. Respiratory gas transport
4. Internal respiration
Chemoreceptors in these two structures detect lowered levels of oxygen in the blood
Carotid arteries
Aorta
