1. renal physiology is a very: imperative component to our body maintaining
homeostasis
2. renal physiology plays a major role in: blood composition and blood pressure
3. renal physiology also plays a major role in: excreting metabolic waste products
that we no longer need (toxins, ions, as well as water)
4. so one fun fact about the kidneys is that it actually receives: 20% of our cardiac
output from the heart
5. The kidneys receiving 20% of our cardiac output from the heart is actually: a really
imperative characteristic because that's our second largest cardiac output that's
received by any one organ
6. The first largest organ that receives a majority of the cardiac output is actually:
the liver
7. The urinary system is composed of: five different components
8. The five main components of a urinary system are: the kidneys (right and left), two
ureters (right and left), one urinary bladder, and one urethra
9. We have a right and left: kidney
10.as seen in image on notes, the right kidney is located: just inferiorly com- pared
to the left kidney
11.Why is the right kidney located just inferiorly to the left kidney?: This occurs
because just below the diaphragm, we have the liver on the right side of the body
and that's what will press the right kidney to be slightly inferiorly or be located
slightly inferior compared to the left kidney
12.We also have right and left: ureters
13.we only have one: urinary bladder
14.and one: urethra
, Renal Physiology PCB Lab
15.As said once before, the urinary system is constantly working to: maintain the
purity and health of the body's fluids by removing any unwanted substances while
trying to recycle others
16.Our body's always going to be trying to: recycle proteins, nucleic acids, things
that are needed inside of the body to be reused
17.Our body's always going to be trying to recycle things that are needed inside of
the body to be reused, and it is going to do so through: a certain process
mechanism
18.The kidneys contribute to homeostasis by: helping to regulate plasma com-
position and it's through the elimination of metabolic waste products.
19.**We have three main metabolic waste products which are: ** (important to KNOW
and TAKE NOTE of): Nitrogenous compounds
20.What are the three main metabolic waste products?: urea, uric acid, and
creatinine
, Renal Physiology PCB Lab
21.The first main metabolic waste product is known as: urea
22.Urea is formed by: the breakdown of amino acids
23.So our body is going to be trying to recycle proteins and through the
breakdown of these proteins: it will form urea
24.Urea is a: nitrogenous compound
25.Our second major metabolic waste product is known as: uric acid
26.Uric acid is formed by: the byproduct of breakdown of nucleic acids
27.So when nucleic acids are going though a turnover,: it will form uric acid
28.Uric acid is a: nitrogenous compound
29.Our last metabolic waste product that we should know is: creatinine
30.Creatinine is formed from: the breakdown of a molecule known as creatine
phosphate
31.creatine phosphate is: a molecule that's found in the muscle tissues that helps
aid in the storage of ATP or the storage of energy.
32.So when creatine phosphate is broken down: it will form the metabolic waste
product of creatinine
33.Creatinine is a: nitrogenous compound
34.The kidneys also deal a lot with: excreting of toxins, excess ions like sodium
and potassium, and even the actual reabsorption of calcium as well as water
35.So the kidneys play a major role in: providing homeostasis to our blood
composition
36.Where are the kidneys located?: They are located in what's knowns as the
retroperitoneal space
37.The retroperitoneal space is: a space that's found just behind the peritoneum of
the abdominal cavity, where the kidneys are located.
, Renal Physiology PCB Lab
38.And the right and left kidney will be located: on the upper abdominal quad- rants
of the retroperitoneal space.
39.As we go through this lecture, we'll hit: every base point on the type of
regulation and what the kidneys function to do.
40.On right hand side in notes, you can see that: our right kidney is located
slightly lower compared to the left kidney
41.Once against, our right kidney is located slightly lower compared to the left kidney
is due to: the presence of the liver on the right side of the body
42.And our right kidney is typically located: between L1 and L3
43.whereas the left kidney is located: more superiority, at T12 through about L3 as
well
44.so we have many functions of the kidney, including:: -Regulation of the
volume, composition, and pH of the body fluids
-Regulation of acid-base homeostasis via the production of ammonia
