	Longitudinal bundles of smooth muscle cells
	Longitudinal bundles of striated muscle fibers
	Spiral bundles of smooth muscle cells
	Spiral bundles of striated muscle fibers

2 What is main function of type II pneumocyte?

	It is a part of neuroendocrine system
	It is a site of diffusion of gases
	It produces a surfactant
	It produces a mucus

3 Which type of muscle tissue is made trachealis muscle?

	Myoepithelium
	Smooth muscle
	Striated muscle
	Mixture of smooth and striated muscle

4 Which type of glands sits in lamina propria mucosae of the trachea?

	Serous

	Stratified squamous keratinizing
	Simple squamous non-keratinizing
	Simple squamous keratinizing

8 Which muscle tissue is a material of the vocal muscle?

	Smooth muscle
	Striated muscle
	Smooth muscle in the caudal part, striated muscle in the cranial part
	Smooth muscle in the cranial part, striated muscle in the caudal part

9 Which of following statements about elastic fibers in lungs is the most accurate?

	There are elastic fibers in the lung, but in the wall of arteries only
	There is plenty of elastic fibers in the lungs
	There are some elastic fibers in the lung
	There are no elastic fibers in the lung

10 Which type of tissue formss an innter "skeleton" of the epiglottis?

	Fibrocartilage
	Elastic cartilage
	Hyaline cartilage
	Dense connective tissue

11 Which of following statements about arteries in the lung circulation is true?

	There is a low pressure in the pulmonary circulation, therefore arteries are thinwalled than arteries in the system circulation
	There is a low pressure in the pulmonary circulation, therefore arteries are thickwalled than arteries in the system circulation
	There is a high pressure in the pulmonary circulation, therefore arteries are thinwalled than arteries in the system circulation
	There is a high pressure in the pulmonary circulation, therefore arteries are thickwalled than arteries in the system circulation
