Simple cuboidal epithelium
Stratified squamous epithelium
Pseudostratified ciliated columnar epithelium
Transitional epithelium
Where are the olfactory chemoreceptors responsible for the sense of smell located?
Respiratory epithelium
Olfactory epithelium
Alveolar epithelium
Tracheal mucosa
In which species is the trachealis muscle found externally instead of internally?
Horse
Pig
Ruminants
Carnivores
What is the primary function of Type II pneumocytes in the alveoli?
Gas exchange
Producing mucus
Producing surfactant to reduce surface tension
Transporting oxygen into the bloodstream
Which characteristic of the tongue allows it to have a high level of mobility?
The presence of papillae
Its orientation within the oral cavity
The arrangement of muscle fibers in multiple directions
Its rich vascularization
What is the composition of the middle portion of the esophagus?
Only skeletal muscle fibers
Only smooth muscle fibers
A combination of skeletal and smooth muscle fibers
A mix of cardiac and smooth muscle fibers
Which part of the small intestine contains prominent Peyer’s patches?
Duodenum
Jejunum
Ileum
Cecum
What structures make up the portal triad in the liver?
Hepatic artery, central vein, bile duct
Portal vein, hepatic artery, bile duct
Sinusoids, hepatocytes, bile canaliculi
Hepatic artery, sinusoids, portal vein
Which of the following best defines the hepatic acinus?
The basic structural unit of the liver based on a vascular perspective
A hexagonal structure centered around the central vein
A unit primarily responsible for bile production
A structure that forms the bile ductules
In conditions of hypoxia or nutritional deficiency, which zone of the hepatic acinus is most susceptible to damage?
Zone 1
Zone 2
Zone 3
Zone 4
What is the primary function of the pancreatic acini in the parenchyma of the pancreas?
Secreting insulin and glucagon
Producing digestive enzymes (serous secretion)
Storing bile for digestion
Filtering blood before entering circulation
Why is the respiratory epithelium classified as pseudostratified?
It consists of multiple layers of cells.
All cells touch the basement membrane, but not all reach the surface.
It has alternating layers of squamous and columnar cells
It is made up of simple columnar epithelium with a stratified arrangement.
What is the functional significance of the trachealis muscle in the trachea?
It prevents airway collapse during inhalation.
It contracts to regulate the diameter of the airway.
It produces mucus to trap pathogens.
It connects the trachea to surrounding structures.
Why does the presence of surfactant in the alveoli prevent lung collapse?
It increases mucus production to keep alveoli open.
It strengthens the alveolar walls against pressure changes
It reduces surface tension, preventing alveolar collapse during exhalation.
It increases oxygen diffusion efficiency.
