Stephen was involved in a major automobile accident which injured his pelvis and fractured the pubic symphysis. Which of the following structures do you think was most likely involved?
Urinary bladder
The glomerulus is a capillary network connected to the afferent and efferent arterioles
True
The filtration membrane is formed by the parietal layer of the bowman’s capsule, fused membranes, and capillary endothelium
False
The area between the renal pyramids is called
Renal columns
When the parasympathetic system acts it will cause
Contraction of the bladder muscle and relaxation of the involuntary sphincter
Urinary infection is more common in females because
There ureters are shorter
The perineal fat surrounding the kidneys is important because
It supports and protects the kidneys
Proximal convoluted tubules are
More numerous
Have larger cuboidal cells
Have smaller lumens
The parasympathetic nervous system will cause
Contraction of the bladder musculature
Which of the following is affected during micturition
Detrusor muscle
The role of the urinary bladder is to
Store and expel urine
The terminal portion of the urinary system is the
Urethra
The JG apparatus play a role in BP regulation
True
Macula densa cells are present in the ascending limb of Henle’s loop and distal convoluted loop
True
Renin is a hormone produced by the JG cells
True
A person suffering from nephrotic syndrome loses large quantities of albumin in the urine this will
Lower osmotic pressure of the blood
The action of ANP is antagonistic to
Aldosterone
Which of the following is reabsorbed actively at the PCT?
Glucose
Extracellular fluid compartment consists of
Plasma and interstitial fluid
Prolonged hyperventilation can cause respiratory alkalosis
True
Most reabsorption of substances from the glomerular filtrate occurs in the
Proximal convoluted tubules
An increase in the permeability of the collecting ducts to water is primarily due to
An increase in the production of ADH
Hypoproteinemia is a condition which has very low levels of plasma proteins . The will be characterized by
Tissue edema
An increase in sympathetic stimulation would tend to____ afferent arterioles thereby _____ the amount of fluid lost and therefore ____ blood pressure
Vasoconstrict , decrease , increase
Which of the below conditions would stimulate a response of decreased glomerular filtration
Low blood pressure
Which of the following substances enters the fluid in the nephron tubules by tubular secretion
Hydrogen ions
Which of the following is not reabsorbed by the proximal convoluted tubule
Creatine
Excretion of dilute urine requires
Impermeability of the distal and collecting tubule water
The kidneys are stimulated to produce rennin
By a decrease in blood pressure
The thirst center is located in the
Hypothalamus
Which of these is impermeable to water
Ascending loop of Henle
The movement of substances from the lumen of the kidney tubules to the blood is known as
Tubular reabsorption
Consider a situation where ketoacidosis occurs and blood ph drops dangerously low. Under this circumstance the nephron would be responded by increased
h+ secretion
The most abundant ion in intracellular fluid is Na
False
The liquid that collects in the cavity of the glomerular capsule can be best described as
Blood minus proteins and cells
A person has been sweating a great deal and has not ingested adequate quantities of water, to make up for the loss his body’s homeostatic mechanisms respond by secreting
Aldosterone and ADH
Peter has just had surgery and us on nasogastric suction. Someone does the suction a little too enthusiastically and removes to much HCL. What do you think will happen to PH?
It will rise
Macy was hemorrhaging and her blood pressure was falling . To maintain homeostasis the body will produce a number of hormones . Which of the following hormones would not be secreted at this time.
ANP
Tom is a tennis player who has been practicing for 3 hours
His tissues are metabolizing and therefore producing excessive C02. His respiratory rate goes up considerably. Why do you think this is happening.
To get rid of the excess H ions that are forming
