Ureters contain sphincters at the entrance to the bladder to prevent the back-flow of urine.
The ureter is innervated by parasympathetic nerve endings only.
The epithelium is stratified squamous like the skin, which allows a great deal of stretch.
The ureters are capable of peristalsis like that of the gastrointestinal tract.
Cotransport with sodium ions.
Reticular connective tissue.
Dense irregular connective tissue.
Loose connective tissue.
Dense regular connective tissue.
It stabilizes the position of the kidneys by holding them in their normal position.
It ensures adequate energy for the adrenal glands to operate efficiently.
It is necessary as a barrier between the adrenal glands and kidneys.
It produces vitamin D.
Surfactant helps increase alveolar surface tension.
A decrease in compliance causes an increase in ventilation.
As alveolar surface tension increases, additional muscle action will be required.
A lung that is less elastic will require less muscle action to perform adequate ventilation.
The pharyngeal-esophageal phase, an involuntary process.
Deglutition which is the elimination of undigested materials.
The gastric phase, activated by distension of the stomach receptors.
The buccal phase, an involuntary phase controlled by swallowing centers in the medulla and pons.
Formation of malic acid from fumaric acid.
Stretch receptors in the alveoli.
Voluntary cortical control.
Composition of alveolar gas.
A fenestrated capillary.
An efferent arteriole.
A vasa recta.
Respiratory exchanges are made through the ductus arterious.
Respiratory exchanges are not necessary.
Since the lungs develop later in gestation, fetuses do not need a mechanism for respiratory exchange.
Respiratory exchanges are made through the placenta.
The buccal glands.
The parotid glands.
The thyroid gland.
The loop of Henle.
The basement membrane of the capillaries.
In the glandular tissue that lines the organ lumen.
In the pons and medulla.
Only in the esophagus because this is the only part of the tract that needs to change to accommodate food passage.
In the walls of the tract organ.
Mucous neck cells
Loss of oxygen in tissues.
Increase of carbon dioxide.
When the specific gravity of urine rises above 1.10.
When the peritubular capillaries are dilated.
By a decrease in the blood pressure
When the pH of the urine decreases.
A decrease in the concentration of the blood plasma.
An increase in the production of aldosterone.
A decrease in the production of ADH.
An increase in the production of ADH.
A cricoid cartilage also called the Adam's apple.
The thyroid cartilage.
An upper pair of avascular mucosal folds called true vocal folds.
Lateral cartilage ridges called false vocal folds.
