What forces help propel urine from the renal pelvis to the urinary bladder? The chief propelling force for the passage of urine from the kidney to the bladder is produced by
peristaltic (wavelike) movements in the ureter muscles
.
How forceful urination is accomplished?
Forceful urination is accomplished by
contraction of abdominal muscles
.
What is forceful urination?
Urinary urgency occurs when the pressure in the bladder builds suddenly, and it becomes difficult to hold in the urine
. This pressure causes a strong and immediate need to urinate. Urinary urgency can occur regardless of whether the bladder is full. It can also make a person want to urinate more frequently than usual.
What muscle controls urine flow?
The
pelvic floor muscle
[also known as the pubococcygeus (pu-bo-kak-sij-e- us) or PC muscle] supports your bladder and rectum and helps control your urine flow.
Which factor is most important in pushing urine from ureter towards the bladder?
Peristaltic contraction
of muscular layer of ureters push urine from kidneys to the urinary bladder but hydrostatic pressure and gravity also plays an imp role.
Over time, your bladder fills up and expands like a balloon, putting tension on the bladder muscles. At a certain point,
the body senses that it is reaching a limit
, which triggers the urge to urinate. But how your body senses a full bladder isn’t known.
So, the correct answer is ‘
Collecting duct –>Ureter –>Bladder –>Urethra
‘.
The detrusor muscle, also detrusor urinae muscle, muscularis propria of the urinary bladder and (less precise) muscularis propria, is smooth muscle found in the wall of the bladder. The detrusor muscle
remains relaxed to allow the bladder to store urine, and contracts during urination to release urine
.
The detrusor muscle (or detrusor urinae muscle)is
the smooth muscle component of the urinary bladder and facilitates contraction of the bladder wall during micturition
.
In men, the need to push urine may be a sign of
bladder outlet obstruction
, which is commonly due to BPH. “This benign condition causes swelling in the prostate and problems starting the urine stream—or a weak flow,” says Dr.
When you finally put the heavy object down, you feel a release in your arms as the muscles relax. Theoretically, these women who are delaying urine are simply
contracting a muscle for a long enough period of time to set off nerves when the muscle is finally released
.
As the urine is collected in the renal pelvis, the pelvic pressure increases and initiates a peristaltic contraction that is propagated along the ureter to the bladder. The peristaltic wave can
move urine against an obstacle, with a pressure of up to 50–100 mm Hg
.
The smooth muscle layer
produces peristaltic waves originating from the renal pelvis and forcing urine along the ureter into the urinary bladder
.
The main force that causes filtration in a nephron is…
glomerular hydrostatic pressure
.
The area at the center of the kidney. Urine collects here and is funneled into the ureter, the tube that connects the kidney to
the bladder
.
The collecting duct system is under the control of antidiuretic hormone (ADH). When ADH is present,
the collecting duct becomes permeable to water
. The high osmotic pressure in the medulla (generated by the counter-current multiplier system/loop of Henle) then draws out water from the renal tubule, back to vasa recta.
So, the correct answer is ‘
Collecting duct –>Ureter –>Bladder –>Urethra
‘.
Glomerular filtration, tubular reabsorption, and tubular secretion are the three primary steps in which kidneys filter blood and maintain proper electrolyte balance.
Glomerular filtration
removes solutes from the blood; it is the first step of urine formation.
