Genitourinary System Flashcards
Which of the following is the correct order of structures that transport urine from the collecting ducts to the urethra?
Collecting ducts, Minor calyces, Major calyces, Renal pelvis, Ureter, Urinary bladder, Urethra.
The basic function of the renal system includes filtration, secretion, reabsorption, and excretion. Which of the following substances is secreted by the nephrons and can be found in the filtrate that is eventually excreted?
Creatinine.
Certain food sources provide more urea than others. Which of the following foods would provide the most urea that would have to be filtered out of the blood via the kidneys?
Proteins, such as meats and eggs.
The renin-angiotensin-aldosterone system (RAAS) is essential in regulating blood pressure. Which of the following hormones involved in RAAS is produced by the kidney?
Renin.
Which of the following is a substance that the kidneys remove from the blood during filtration?
Salts.
Where are the glomeruli and Bowman’s capsules found?
Renal cortex.
________ is not normally found in urine, and its presence may indicate a problem with the kidneys.
Albumin.
Which of the following is true of the vasculature of kidneys?
Blood vessels enter and exit the kidney at the same point as the renal pelvis becomes the ureter, which is the renal hilum.
One of the primary functions of the kidney is to filter blood in order to remove substances that have no useful function in the body. Which of the following is the correct path of blood from the abdominal aorta to the inferior vena cava (IVC)?
abdominal aorta – renal arteries – segmental arteries – interlobar arteries – arcuate arteries – interlobular arteries – afferent arteries – glomerulus – efferent arteries – peritubular capillaries – interlobular veins – arcuate veins – interlobar veins – renal veins – inferior vena cava.
What is the upper expanded region of the ureter called?
Renal pelvis.
_______ is the site of blood filtration in the human body.
The kidney.
Which of the following secretes the antidiuretic hormone?
Pituitary gland.
In the presence of antidiuretic hormone (ADH), or vasopressin, water is mostly reabsorbed in the ___________ of the nephron.
Proximal convoluted tubule.
The functional unit of the kidney is the nephron. A nephron is made up of renal tubules and renal corpuscles, both of which perform different functions. Which of the following parts of the nephron is not correctly paired with its function?
Collecting Ducts – Secretion of water.
Which of the following components of renin-angiotensin-aldosterone system (RAAS) is not correctly paired with its function?
Aldosterone – sodium and water reabsorption.
