Metabolic wastes are substances that are left over from metabolic processes. These substances cannot by used by the organism.
true
false
All of the metabolic wastes are excreted as water soluble solutes by the kidneys.
true
false
Carbon dioxide is considered metabolic waste and is excreted though the lungs.
true
false
Nitrogenous wastes are produced from the breakdown of nitrogen-containing compounds like amino acids and nucleotides.
true

In humans, the main nitrogenous waste produced is ____.

State 3 stages of urine formation?
(a)
_____________ is the first step of urine formation; water and certain dissolved substances are filtered out of capillaries into a glomerular capsule.
Tubular Reabsorption
Tubular Secretion
Glomerular Filtration
_____________ is the second step of urine formation; substances move from the tubular fluid back into the blood.
Tubular Reabsorption
Tubular Secretion
Glomerular Filtration
_____________ is the third step of urine formation; substances move from the blood into the fluid of the renal tubule
Tubular Reabsorption
Tubular Secretion
Glomerular Filtration
What is the name of the process within the kidney where high pressure forces fluids (water) and dissolved substances (salt, urea, nutrients) through the walls of the capillaries of the glomerulus into the Bowman’s capsule.
Secretion
Reabsorption
Excretion
Filtration
What is the name of the process where water, salts and nutrients move by diffusion or active transport from the Loop of Henle into the surrounding capillaries.
Secretion
Reabsorption
Filtration
Excretion
Name the process in the kidney where excess ions and chemicals (e.g drugs) are secreted from surrounding capillaries into the tubule.
Secretion
Reabsorption
Filtration
Excretion
The plasma that is filtered by all of the glomeruli in both kidneys as a function of time is called the glomerular filtration rate.
true
false
The ___________mechanism is how arteries and arterioles react to an increase or decrease of blood pressure to keep the blood flow within the blood vessel constant.
myogenic
tubuloglomerular feedback
____________is an adaptive mechanism that links the rate of glomerular filtration to the concentration of salt in the tubule fluid at the macula densa. A high [NaCl] and reabsorption rate at this site causes contraction of the afferent arteriole and a reduction in GFR.
myogenic mechanism
tubuloglomerular feedback
The __________ is responsible for contraction of the urinary bladder during micturition.
trigone
detrusor muscle
micturition muscle
internal urinary sphincter
Why is the external urinary sphincter under conscious control?
It is made of adventitia.
It is made of skeletal muscle.
It is made of smooth muscle.
It is part of the detrusor muscle.
Voluntary micturition
is a reflex action.
is common in infants.
involves higher brain centers.
involves control of the internal sphincter.
The urge to urinate results from the ____________.
micturition reflex
unmicturition reflex
voluntary urinary mechanism
involuntary urinary mechanism

Distal convoluted tubule
The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and its main function is to regulate blood pressure and the filtration rate of the glomerulus.
