Urinary elimination

kidneys and the ureters
what is apart of the lower urinary tract?
urinary bladder, urethra, and pelvic floor
the primary regulator of fluid and electrolytes and acid base balance
the kidney
the urine is formed here. the blood is filtered and the waste is then removed.
nephron
tiny capillaries that are surrounded by bowman’s capsule that make up a nephron. This is the exact location of where the blood is filters.
Glomerlus
Most _____ occurs in the glomerulus. Blood pressure forces water, salt, glucose, amino acids, and urea into Bowman’s capsule. Proteins and blood cells are too large to cross the membrane. The remain in the blood. The fluid that enters the renal tubules is called the ____.
filtration ; filtrate
As the filtrate flows through the renal tubule, most of the water and nutrients are _______ into the blood. The concentrated fluid that remains is called urine.
Reabsorption
water and electrolytes are mainly absorbed here
The proximal convoluted tubule
glucose is mainly absorbed here
The loop of henle
Tubular secretion takes place here, and where additional sodium and water will be reabsorbed back into the blood depending on two hormones. ADH and aldosterone.
Distal convoluted tubule
When fluid intake is low or there is an increase in the amount of solute in the blood the pituitary gland releases _____.
ADH
involuntary urination in children beyond the age of when voluntary control of the bladder is acquired.
Enuresis
when the bladder is over extended to empty the bladder completely

Medical/pathological condition/surgical
what has the ability to inhibit the release of ADH

List the factors affecting urinary elimination
developmental, physcho-social-cultural, medical/pathological/surgical, diagnostic procedures, nutrition and hydration, activity and position, muscle tone, medications, neuromuscular disease
sudden strong desire to void
urgency

frequency
