Oxygen is predominantly transported in the blood in dissolved form

The diaphragm is the primary muscle involved in exhalation

Total lung capacity is the amount of air expelled during maximal exhalation

Intrapleural pressure is always lower than atmospheric pressure during normal breathing

The main function of bronchioles is gas exchange

Total lung capacity is the maximum amount of air that can be exhaled after maximal inhalation

Surfactant is produced by epithelial cells in large airways

The Bohr effect describes increased oxygen release from hemoglobin when pH decreases

There are 4 binding sites for oxygen molecules in a hemoglobin

During inhalation, chest expand because of air moving into lungs

Bronchoconstriction can lead to shortness of breath in asthma patients

Inspiration is always an active process requiring energy

Inspiratory reserve volume is the amount of air that can be inhaled after a normal breath

Air movement in the lungs occurs due to pressure differences

The primary function of the respiratory system is to process aerobic metabolism

The respiratory process involves repeated inhalation and exhalation

Hemoglobin cannot bind to carbon dioxide

The right lung has two lobes

Alveoli are lined with thick connective tissue to support their structure

Baroreceptors in the lungs control the breathing rate

Gas exchange occurs via the process of simple diffusion

Respiratory rate can be increased without changes in carbondioxide levels in the blood

Factors affecting ventilation include lung elasticity and airway resistance

Lung tissue has a rich blood supply to facilitate gas exchange

Inefficient ventilation does not affect carbondioxide levels in the blood

Oxygen diffuses more easily than carbon dioxide

Increased temperature can decrease hemoglobin's affinity for oxygen

Increased pH can decrease hemoglobin's affinity for oxygen

Increased carbondioxide in blood can decrease hemoglobin's affinity for oxygen

Increased 2,3 BPG in blood can decrease hemoglobin's affinity for oxygen

Intercostal muscles aid in breathing by altering thoracic volume

Alveolar pressure increases during exhalation

Intrapleural pressure increases at the beginning of exhalation

Pulmonary ventilation occurs automatically without nervous system influence

Gas diffusion is affected by concentration gradients

The use of snorkel tube can help decrease airway resistance

Breathing patterns are not influenced by emotions

Hyperventilation can lead to respiratory alkalosis

Alveoli have thin walls to facilitate efficient gas exchange

Lung tissue does not require a blood supply for normal function

Pulmonary arteries carry oxygen-rich blood

Gas diffusion occurs from areas of high concentration to low concentration

Pulmonary ventilation is unaffected by airway resistance

Elevated PO2 in the blood can stimulate the respiratory center in the brain

Elevated PCO2 in the blood can stimulate the respiratory center in the brain

Deep breathing involves only the diaphragm without other muscles

Dissolved gases in blood plasma do not play a role in gas exchange

All oxygen inhaled is used in cellular respiration processes

Pulmonary edema decreases gas exchange due to increase diffusion distance
