Question

Which statement about glomerular filtration is FALSE?

1) the glomeruli function has very efficient filters of blood
2) glomerular filtration is an "active" and very selective process in filtering most solutes
3) solutes and fluid are forced through a filtration membrane by hydrostatic pressure
4) glomerular filtration is a passive, non-selective process
5) is dependent on vasomotor activity, blood volume and arterial pressure

Answer 1

The false statement about glomerular filtration is that it is an "active" and very selective process; it is instead a passive, non-selective process driven by hydrostatic pressure.

Step-by-step explanation:

The statement about glomerular filtration that is FALSE is that glomerular filtration is an "active" process. In reality, glomerular filtration is a passive, non-selective process that relies on hydrostatic pressure to force solutes and fluid through a filtration membrane. This process occurs in the kidneys' glomeruli, where the blood pressure facilitates the movement of solutes except for larger molecules like proteins. The glomerular filtration rate (GFR) is dependent on various factors such as blood volume, arterial pressure, and vasomotor activity, making it a crucial indicator of kidney function.

Thus, the correct final answer is that statement 2) "glomerular filtration is an 'active' and very selective process in filtering most solutes" is the FALSE statement. Glomerular filtration is actually characterized by its non-selectivity and passive mechanism, and no energy is used during the filtration of blood into the glomerular capsule.
