Respiratory rate (multiple choice) Flashcards
(20 cards)
The consumption of oxygen and production of carbon dioxide by metabolism within the mitochondria is known as
External respiration
Internal respiration
Cell respiration
Gas transport
Cell respiration
The functional unit of the respiratory system is the
Alveolus
Capillary
Villus
Bronchiole
Alveolus
The oxygen concentration in atmospheric air is approximately
5%
20%
50%
80%
20%
The blood circulation to and from the lungs is known as the
Hepatic portal circulation
Coronary circulation
Systemic circulation
Pulmonary circulation
Pulmonary circulation
The substance secreted into the fluid lining the alveoli that prevents their collapse is known as
Cholesterol
CSF
Surfactant
Serous fluid
Surfactant
The proportion of a gas in a mixture of gases is known as the
Partial pressure
Proportional pressure
Relative pressure
Hydrostatic pressure
Partial pressure
The globular protein responsible for transport of oxygen in blood is known as
Haemacel
Haemoglobin
Albumin
Cyanocobalamine
Haemoglobin
The trachea has multiple horseshoe rings supporting the muscle tissue, they are made from
Fibrous connective tissue
Bone
Cartilage
Epithelium
Cartilage
The gas exchange process at the level of the capillary and the body tissues is called
External respiration
Internal respiration
Cell respiration
Gas transport
Internal respiration
The trachea is lined with
Epithelial Villi
Epithelial microvilli
Ciliated epithelium
Squamous epithelium
Ciliated epithelium
Among the tracheal lining cells are mucous producing cells called
Kupfer cells
Columnar cells
Bronchial cells
Goblet cells
Goblet cells
The pleural membrane closest to the lung tissue is called
Parietal membrane
Visceral membrane
Peri-pleural membrane
Intra-pleural membrane
Visceral membrane
The movement of air into the lungs occurs because
The lung capacity is increased by the diaphragm and intercostal muscles reducing pressure inside the lungs
The lung capacity is decreased by the diaphragm and intercostal muscles increases pressure inside the lungs
Contraction of the intercostal muscles pulls air into the lungs
The action of the diaphragm causes a rise in intrapleural pressure
The lung capacity is increased by the diaphragm and intercostal muscles reducing pressure inside the lungs
Air movement in ventilation is based on
Osmotic pressure
Hydrostatic pressure
Pressure gradients
Suction
Pressure gradients
The products of cell respiration
Oxygen and water
Carbon dioxide and water
Carbon dioxide and glucose
Carbon dioxide
Carbon dioxide and water
The nasal cavity contains narrow passageways lined with moist tissue to warm and humidify the incoming air. These passageways are called:
Nasal turbinates or conchae
Nasal foramina or canals
Nasal meatus
External naris
Nasal turbinates or conchae
The structure that protects the tracheal opening from food entrance is called the
vocal cords
false cords
thyroid cartilage
epiglottis
epiglottis
The widened section of the trachea that houses the opening is called the
pharynx
larynx
epiglottis
eustachian canal
larynx
The nostril is called the
nasal orifice
nasal meatus
external naris
rhinal meatus
external naris
The internal architecture of the nasal cavity is formed by which bone
The ethmoid bone
The sphenoid bone
The Mandible
The maxilla
The ethmoid bone
