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

Urinary system and sweat glands

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.

the answer is trees if i'm not mistaken

d. groundwater flows through the subsoil and deposits minerals.
