Air moves into the lungs when pressure inside the lungs is ___A___ than the
atmospheric, and air moves out of the lungs when pressure inside the lungs in
___B___ than atmospheric
A - less
B - greater
T/F : Fetal hemoglobin isoform has lower affinity compared to the adult
hemoglobin.
False
T/F : Pleural fluid adhesive force prevents alveoli the lungs to collapse and allows
fetal lung maturity
True
T/F : Among the fluid entering in the digestive system only 2 L derived from daily
consumption
True
T/F : Pancreas, liver, and gallbladder are accessory glandular organ that help with
the digestion process
True
T/F : The medulla oblongata in the brainstem, is responsible for the ventilation
,False
T/F : The pressure gradient is a bulk of air flow between lungs and atmosphere
True
T/F : Peyer's patches of the gut-associated lymphoid tissues (GALT) are in the
muscularis layer of the GI tract wall
False
T/F : Renal portal system allows filtration of the fluid out of the blood into the
lumen of the nephron at the glomerular capillaries then reabsorption of fluids
back from the tubules lumen back in the blood at the peritubular capillaries
True
What contraction is responsible for forward movement
Peristaltic contraction
What contraction is responsible for mixing
Segmental contraction
What are the four functions of the respiratory system
1. Exchange of gases between the atmosphere and the blood
2. Homeostatic regulation of body pH -> CO2
3. Protection from inhaled pathogens and irritating substances
4. Vocalization -> air moving via the vocal cords creates vibrations
Four stages of external respiration
1. The exchange of air between the atmosphere and the lungs
2. The exchange of O2 and CO2 between the lungs and the blood
, 3. The transport of O2 and CO2 by the blood
4. The exchange of gases between blood and the cells
Which lung has 3 lobes
Right Lung
Why does the left lung only have 2 lobes?
The left lung is a little smaller than the right lung because it has to make space for the
heart (the cardiac notch) in the left side of the throacic cavity
What is included in the upper respiratory system?
Pharynx, vocal cords, esophagus, nasal cavity, tongue, and larynx
What is included in the lower respiratory system?
Trachea, right lung, right bronchus, diaphragm, left lung, left bronchus
What are the three lobes of the right lung
superior, middle, inferior
What are the two lobes of the left lung
superior and inferior
Fluid buildup between tissues that line the lungs and the heart
Pleural Effusion
What membrane is around the lungs
Pleural membrane
What cavity surrounds the heart
pericardial cavity
What creates the force to move air during breathing
muscles of the thorax, neck, and abdomen
