Vestibular Fold
39
controlled by the tension of the vocal folds
Pitch
40
Lower sounds are produced by
decreased muscular tension
41
What organ prevents the food from going to the trachea and diverts the food to go to the esophagus?
Epiglottis
42
Badingbadingbading
- asli
43
tubular passageway for air that is about 12 cm (5 in.) long and 2.5 cm (1 in.) in diameter. It is located anterior to the esophagus
Trachea or Windpipe
44
divides into a right main (primary) bronchus, which goes to the right lung, and a left main (primary) bronchus, which goes to the left lung.
Trachea
45
What muscles are found in the trachea
Smooth muscle
46
What is the type of respiratory epithelium found in the linings of the trachea as well as other respiratory tract, which allows filtering and humidification of incoming air?
pseudostratified ciliated columnar epithelium.
47
the trachea divides into a right main (primary) bronchus, which goes into the right lung, and a left main (primary) bronchus, which goes into the left lung
Main Bronchi
48
the main bronchi divide to form smaller bronchi
Lobar (secondary) Bronchi
49
The lobar bronchi continue to branch, forming still smaller bronchi, called
Segmental Bronchi
50
Branch into even smaller tubes called terminal bronchioles. Because all of the airways resemble an upside-down tree with many branches, their arrangement is known as the bronchial tree.
Bronchioles
51
paired organs in the thoracic cavity enclosed by the pleural membrane.
Lungs
52
The parietal pleura is the?
The outer layer
53
The visceral pleura is the
The inner layer
54
the pleural cavity, which contains a small amount of lubricating fluid secreted by the?
membrane
55
reduces friction between the membranes, allowing them to slide easily over one another during breathing?
Pleural Fluid
56
Pleural fluid also causes the two membranes to adhere to one another just as a film of water causes two glass microscope slides to stick together, a phenomenon called?
Surface tension
57
How many lobes and fissures are there in the right lung
3 lobes and 2 Fissures
58
How many lobes and fissures are there in the left lung

70
which are combinations of different lung volumes
Lung capacities
71
The record is called a_______. Inhalation is recorded as an upward deflection, and exhalation is recorded as a downward deflection
Spirogram
72
Air is a mixture of what gases
nitrogen, oxygen, water vapor, carbon dioxide, and others
73
The pressure of a specific gas in a mixture is called
Partial pressure
74
in ________________ O2 and CO2 move from areas of higher partial pressure to areas of lower partial pressure.
external and internal respiration
75
(pulmonary gas exchange) is the exchange of gases between alveolar air and pulmonary blood capillaries.
External Respiration
76
is the diffusion of O2 from air in the alveoli of the lungs to blood in pulmonary capillaries and the diffusion of CO2 in the opposite direction.
External Respiration
77
in the lungs converts deoxygenated blood (depleted of some O2) coming from the right side of the heart into oxygenated blood (saturated with O2) that returns to the left side of the heart
External Respiration
78
(systemic gas exchange) is the exchange of gases between systemic tissue capillaries and systemic tissue cells.
Internal Respiration
79
The exchange of O2 and CO2 between systemic capillaries and tissue cells
Internal Respiration
80
Function of blood in respiration
transport gases
81
About what percent of blood O2 is bound to hemoglobin in red blood cells?
98.5% DO YOU BELIEVE IT? OMG ITS ALOT jk sleep well
82
Carbon dioxide is transported in three ways:
1. 7 percent is dissolved in plasma 2. 23 percent combines with the globin of hemoglobin 3. 70 percent is converted to bicarbonate ions (HCO3 – )
83
made up of two collections of neurons called the dorsal respiratory group (DRG), formerly called the inspiratory area, and the ventral respiratory group (VRG), formerly called the expiratory area.
Medullary Respiratory Center
84
The inspiratory area sets the basic rhythm of respiration.
Pontine respiratory group (in pons)
85
two division of The respiratory center:
1. Medullary Respiratory Center 2. Pontine Respiratory Group
86
it may be modified by several factors: cortical influences; chemoreceptors; limbic system stimulation; proprioceptor stimulation; temperature; pain; irritation of airways; the inflation reflex (stretch receptors).
Respiration
