Chapter 15, Problem 1AWK
Summary Introduction
To review:
The workload on the kidneys after a person consumes a salty snack and a beverage.
Introduction:
The excess amount of salt and water are readily excreted through the kidneys. Unlike normal conditions with a normal salt and water intake, here the kidneys have to work harder to get rid of the extra ions. This is essential for the maintenance of the ionic balance in the blood, which in turn, maintains homeostasis.

Students have asked these similar questions
Someone has the following data of kidneys:
Filtrate= 180 L/day
Water=75% reabsorbed
Urine =4 L/day
NA+ =99.5% reabsorbed
Urea=44% reabsorbed
Glucose =60% reabsorbed
The perone is____________
. diabetic
.hypoglycemic
.psychotic
. ketonemic
On a particularly busy day, a student taking Anatomy and Physiology does not have anything to drink from 9:30 am until 6:30 pm. Osmoreceptors in the brain detect the decreased level of water in the blood. These receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone (ADH). This hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. This retention of water has the additional effect of decreasing urinary output. As the fluid levels in the blood stabilize, the release of ADH ends.1. Whatisthevariablemonitoredbythisloop?2.

Kidneys serve two critical roles in vertebrates; #1 they
balance the concentration of salt to water inside the body and
# 2 they remove waste from the blood while saving sugar and
protein.
