Which tissue layer has Areolar connective tissue with many blood and lymph vessels and submucosal neuron plexus
Mucosa
Submucosa
Muscularis
Serosa
What is the function of the intrinsic muscle?
•hold tongue in position, and move tongue to maneuver food and for swallowing
•anchors inferiorly and limits movement posteriorly
alter shape and size of tongue for speech and swallowing
projections of lamina propria covered with epithelium, contain taste buds and receptors for touch, and increase friction
True or False
Chemical digestion involves Mechanical digestion and mixes food with saliva. Shapes into soft, flexible bolus for swallowing
True
False
How does food move from the mouth to stomach?
Voluntary stage
Pharyngeal stage
Esophageal stage
All of the above
What 2 sphincters can be found in the stomach?
Lower esophageal
pyloric
Rug
I want 10 points
Yes
No
Which filtration membrane 1.make up deepest layer of filtration barrier. Fenestrations – large pores between endothelial cells; make them “leaky” and still prevent large substances like blood cells, platelets, and large proteins from exiting capillary blood flow
Fenestrated glomerular capillary endothelial cells
Basal lamina
Visceral layer
Select all that apply
What are the 2 forces that generate filtration pressures that drive fluid movement in typical capillary bed
Glomerular hydrostatic pressure (G H P)
Hydrostatic pressure
net filtration pressure (N F P)
Colloid osmotic pressure (C O P)
What does Angiotensin-II promote
Vasoconstriction of efferent arterioles and systemic blood vessels
Reabsorption of sodium ions, chloride ions and water from proximal tubule
Aldosterone release, further promoting sodium and water reabsorption
Increased thirst
All of the above
(true or false)
Atrial natriuretic peptide (A N P) hormone released by heart cells in atria in response to increasing fluid volume; lowers blood volume and blood pressure to reduce workload of heart
True
False
____________ - substances must pass from filtrate in lumen (inside) of tubule across or between tubule cells, into interstitial fluid, and finally across or between endothelial cells of peritubular capillaries to reenter blood
Paracellular
Transcellular
Tubular Reabsorption
tubular secretion
___________ - – transport sodium ions from filtrate into tubule cell with other substances like glucose
Carrier protein
Na Symporter
Na/H anitporter
(true or False)
Aquaporins are water channels in both apical and basolateral cell membranes; greatly increase reabsorption of water
True
False
True or False
Cells of distal tubule lack microvilli therefore do not require microvilli to perform function of reabsorbing remaining water and solutes
True
False
Which hormone does the following:
•Stimulates urinary excretion of sodium ions (natriuresis)
•Inhibits release of both aldosterone and A D H
•Causes fewer sodium ions (and also less water) to be reabsorbed; results in more water and sodium excretion
ADH
ANP
Aldosterone
I want a free point
.
Yes
True or false
Darker urine is more concentrated; has more water
True
False
What is the Trigone?
deepest layer; mucous membrane composed of transitional epithelium; capable of expanding and contracting
most superficial layer; made of fibrous connective tissue that supports ureter
triangular region on bladder floor; openings of two ureters are at each posterior corner
innermost layer; made of transitional epithelium and underlying basement membrane; protects bladder from urine
I want a free point
