Exam 3. Respiration, Digestion, and Metabolism
Which of the lungs is larger and why?
The right lung is larger because of the cardiac notch located on the left lung
Name the 3 Lobes of the right lung
Superior, Middle, Inferior
Name the 2 Lobes of the Left Lung
Visceral Pleura is located where on the lung?
it is attached to the lung as the lining
What happens to the diameter of the tubing from outside of lungs to inner lungs?
Decreases in diameter
Name the 3 Functions of the Respiratory System
-gas exchange -vocalize -pH Balance
3 Conchae of the Nasal Cavity
-superior, middle, inferior
secrete mucus in the nasal cavity and trap particles
Name the paranasal sinuses
-frontal Function to lighten skull, humidify and warm the air we
Millions in lungs, site of gas exchange-- air sacs covered with capillaries
Are bronchioles skeletal or smooth muscle
Smooth muscle - involuntary
After splitting off from the trachea name the pathway into lungs:
Trachea is made up of what type of tissue:
Pseedostratified ciliated columnar epithelium
3 Regions of the Pharynx (Throat):
C-shaped cartilage of larynx & trachea
reduces surface tension like thin film of oil, doesn't allow alveoli to stick together.
Measuring of Lung Capacity/Volumes
Maximum Amt. of Air a person can forcefully exhale after a max inhalation
The amount you inhale/exhale during normal quiet breathing:
Bacterial disease spread thru air, forms crust over alveoli:
What Controls Respiration?
ANS, Limbic System
What effects respiration?
pH, partial pressure of Co2 in blood, partial pressure of O2 in blood
Normal Blood pH:
covers thoracic wall where ribs are
is located right on the lungs
Fluid located between visceral and parietal pleura:
Extension of pleura onto the diaphragm
Major breathing muscle controlled by the phrenic nerve
Disease of lungs where surface are decreases due to low numbers of alveoli, meaning decreased O2 entering the blood:
not enough oxygen in the tissues
