Osmoregulation: Salt and Electrolytes Excretion

Question 1

the process of
maintaining salt and
water balance across membranes
within the body.

Answer 1

Osmoregulation

Question 2

is based largely on controlled
movement of solutes between internal fluids and
the external environment

Answer 2

Osmoregulation

Question 3

expend energy to control water uptake and loss in a hyperosmotic or hypoosmotic
environment

Answer 3

Osmoregulators

Question 4

maintains the proper balance of electrolytes in the human body, despite
external factors such as temperature, diet, and
weather conditions.

Answer 4

Osmoregulation

Question 5

internal osmolarity nears that of the external environment

Answer 5

Osmoconformer

Question 6

Maintains internal osmolarity within an narrow range
regardless of the external environment.

Answer 6

Osmoregulators

Question 7

Types of Regulation of Blood
Plasma 3 or the OOI

Answer 7

Osmotic regulation
Osmotic conformer
Ionic regulation

Question 8

Types of Osmotic regulation and Conformity 3 or the IVV

Answer 8

Ionic conformity
Volume regulation
Volume conformity

Question 9

maintains
a constant or nearly constant osmotic pressure
in the blood plasma

Answer 9

Osmotic regulation

Question 10

the blood osmotic
pressure always equals the osmotic pressure of
the environmental water

Answer 10

Osmotic conformer

Question 11

maintains of a constant or
nearly constant concentration of an inorganic ion
in the blood plasma.

Answer 11

Ionic regulation

Question 12

allows the concentration of
the ion in its blood plasma to match the concentration in its external environment.

Answer 12

Ionic conformity

Question 13

is the regulation of the total
amount of water in a body fluid

Answer 13

Volume regulation

Question 14

refers to completely
passive changes

Answer 14

Volume conformity

Question 15

animals that can only tolerate a narrow range of salt Concentrations

Answer 15

Stenohaline

Question 16

animals that can tolerate widely variant osmolarities

Answer 16

Euryhaline

Question 17

Animals that excrete nitrogenous wastes
as BLANK need lots of water

Answer 17

Ammonia

Question 18

The liver of mammals and most adult amphibians converts ammonia to less
toxic

Answer 18

Urea

Question 19

is largely insoluble in water
and can be secreted as a paste with little water loss

Answer 19

Uric Acid
