The overall goal of the RAA (renin-angiotensin-aldosterone) system is to increase or decrease blood pressure?

increase

100

How does the RAA system and angiotensin II influence GFR?

decreases GFR by vasoconstriction of the afferent arteriole: this conserves fluid which helps increase blood volume and blood pressure

100

Tubular secretion is movement from the _________ into the __________.

blood

tubules (filtrate/urine)

100

Which forces oppose filtration at the glomerulus?

bowman's capsule hydrostatic pressure

blood colloid osmotic pressure

200

Which type of nephron is the most common type?

cortical

200

The ______________ release renin in response to low blood pressure and are a part of the ____________.

granular cells

juxtaglomerular apparatus

200

Type of diabetes that involves hyperglycemia and glycosuria.

Diabetes mellitus

200

Connects the kidneys to the bladder.

ureters

300

Where does unregulated reabsorption occur?

the proximal convolute tubule

300

Tubular reabsorption is movement from the ________ into the ___________.

Tubules (filtrate)

blood

This is something we want to keep, so it is moved from the tubules back into the blood stream

300

In order for something to become part of the urine it must be _________ or __________ but not _____________.

filtered

secreted

reabsorbed

300
What are the functional units of the kindey?

nephrons

400
How does ANP (atrial natriuretic peptide) influence Na+ reabsorption?
it decreases reabsorption of Na+ at the distal convoluted tubule and collecting duct by removing Na+ channels and pumps
400

______________ is the maximum concentration of a substance in the blood before tubular maximum is exceeded and it appears in the urine.

renal threshold

400

Type of nephron that has a longer loop of henle and forms the vertical osmotic gradient.

juxtamedullary nephron

400

Tubular components of a nephron carry _________.

filtrate (urine)

500

What is the main force driving glomerular filtration rate?

capillary hydrostatic pressure

500

If blood volume is low, _____________ would cause more water to be reabsorbed by insertion of ________________ at the DCT and collecting duct.

more ADH release

aquaporins

500

The filtrate is initially collected by ____________ and then flows into the ______________.

Bowman's capsule

proximal convoluted tubule

500

Regulated reabsorption involves ___________ and typically occurs at the _______________.

hormones

DCT and collecting duct
