The main force that promotes filtration in a nephron is:

glomerular hydrostatic pressure (GHP).

The glomerular filtration rate is defined as:

the amount of filtrate formed by both kidneys in one minute

What effect does high blood pressure have on the glomerular filtration rate (GFR) in the absence of regulatory mechanisms?

GFR will increase.

What will NOT stimulate the renin-angiotensin-aldosterone system (RAAS)?

an increase in systemic blood pressure

It involves carrier-mediated transport.

Most nutrients, such as glucose, are reabsorbed in the __________.

proximal tubule

Promotes vasoconstriction of efferent arterioles and systemic blood vessels

angiotensin-II (A-II)
