simple squamous epithelium lines the bronchioles
which region of the bronchial tree directly serves the bronchopulmonary segments?
tertiary (segmental) bronchi
what is the function of the nasal conchae?
they cause turbulent air flow within the nasal cavity
which of the following components of the larynx consists of a "shield" of hyaline cartilage containing the laryngeal prominence or Adam's apple?
thyroid cartilage
this type of epithelium lines the mucosa of the uterus, urinary bladder, and first part of the urethra?
transitional
in the lung, which of the following most accurately describes the diffusion barrier for gases across the wall of alveoli?
type I alveolar cells, capillary endothelial cells, and the fused basal laminae from both of these cell types
in the lung, the surface tension of the inner lining of alveoli is reduced by pulmonary surfactant produced by...
type II alveolar cells
in the juxtaglomerular complex, the macula densa is part of which structure?
efferent arterioles
the ___________ covers the opening to the larynx when we swallow food
epiglottis
sperm are moved into the epididymis from the testis by...
fluid produced by Sertoli cells and contractions of myoid cells
this layer of the uterus detaches and passes out of the vagina at the end of the menstrual cycle
functional layer of endometrium
which of the following best describes the path of filtered plasma as it passes through the uriniferous tubules?
glomerular capsule, proximal convoluted tubule, loop of Henle, distal convoluted tubule, collecting duct
the cells in the testes that produce testosterone are __________
Leydig cells
enzymes that are necessary for fertilization are located within the _________ of mature spermatozoa
acrosome

anterior renal fascia
the vocal ligaments (true vocal cords) attach between the thyroid cartilage and the __________ of the larynx
arytenoid cartilages
which of the following is NOT part of the filtration membrane in the kidney?
basement membranes of both type I alveolar and pulmonary capillaries ARE PART: intercellular clefts of glomerular capillaries, podocyte foot processes, juxtaglomerular (granular) cells, and fenestrae of glomerular capillaries
Supportive cartilage disappears from the bronchial tree at the level of the
bronchioles
what type of epithelium lines respiratory mucosa?
ciliated pseudostratified columnar epithelium
microscopically, distal convoluted tubules in the kidney can be distinguished from proximal convoluted tubules based on...
the distal convoluted tubules have a larger diameter lumen
in the ovary, a difference between a primary follicle and a primordial follicle is that...
the primordial follicle has only a single layer of flat, squamous follicular cells, whereas the primary follicle has a single layer of cuboidal follicle cells
in addition to granulosa cells, these cells contribute to the outermost layer of late secondary and mature follicles in the ovary
theca cells
