Question

Homeostasis depends on the activity of body systems to adjust a variable. Because our bodies work so well to maintain variables at set point, we often do not even notice the systems they use to do it. But in someone who is ill, these systems may not be able to maintain homeostasis; you need to be aware of this to head off possible problems. Which of the following are body systems that can directly impact fluid balance?

.

a)throat muscle

b)urinary system

c)respiratory system

d)muscles

e)hearing

f)sweat glands

g)reproductive system

Answer 1

Answer: Urinary system and sweat glands

Step-by-step explanation:

Homeostasis is simply the maintenance of a stable internal environment. Therefore, to ensure fluid-balance:

I) the urinary system does the following:

- selective reabsorbtion of nutrients such as glucose, amino acids, sodium, calcium from the urine to electrolyte balance

- excretion of concentrated urine during high temperature to prevent dehydration, while large volume of dilute urine during low temperatures (cold weather) to prevent excess body fluid

II) the sweat glands does the following:

- excretion of heated water from body cells through sweat pores in the skin to aid cooling of body organs.

- dilation of blood vessels (vasodilation) to allow sweat production; constriction of blood vessels (vasoconstriction) during cold to allow water retention in the body.

Answer 2

Answer: body systems that can directly impact fluid balance includes:

b)urinary system

c)respiratory system

f)sweat glands.

The correct option is B, C and F.

Step-by-step explanation:

Homeostasis is the mechanism by which the body maintains a steady ( constant) internal physical and chemical conditions. The following variables needs to be kept in equilibrium for optimal functioning of the body system. They includes: the body temperature, fluid balance, blood sugar levels. These variables are in turn controlled by one or more regulatory systems which includes;

- urinary system:when blood volume gets too low or blood electrolytes get too concentrated, the kidneys can retain water thereby decreasing urine output. When blood volume or pressure is too high, the kidneys can excrete more water thereby increasing urine output.

- sweat glands: this regulates both fluid and temperature.

I hope this helps. Thanks
