The major route of intake of water is by ingestion of fluids and food. Food contains water, and additional water is produced during oxidation of carbohydrates. The major routes of water loss are urine, feces, sweat and insensible water loss by
evaporation from the respiratory tract and diffusion through the skin
[1].
What system is responsible for the most common route of water loss from the body quizlet?
acid-base balance. What system is responsible for the most common route of water loss from the body?
sensible water loss
.
What is the major source of water loss from the body?
The main sources of water losses from the body are
urine and sweat
, but water is also lost through stools and insensibly through skin and breathing.
In which fluid compartment is the largest percentage of the body’s water located?
Most of the water in the body is
intracellular fluid
. The second largest volume is the interstitial fluid, which surrounds cells that are not blood cells.
What is the primary regulator of water loss?
What is the primary regulator of water loss? The primary regulator of water loss is
the control of urine production
.
What is the greatest regulator of water intake?
| Question Answer | What is the greatest regulator of water intake? A)renal function B)gastrointestinal system C)adequate diet D)hypothalamus d) Thirst is the greatest regulator of water intake and is controlled in all animals by neurological centers in the hypothalamus and limbic system. |

What are examples of insensible water loss?
[1] The majority of fluid loss occurs in urine, stool, and sweat but is not limited to those avenues. Insensible fluid loss is the amount of body fluid lost daily that is not easily measured, from the respiratory system, skin, and
water in the excreted stool
.
How much urine is lost through obligatory water loss each day?
Mechanisms to control intake also operate but are less elaborate. 1. Obligatory water loss – even under ideal conditions the body will lose
about 700 mL per day
through the lungs and skin. An additional 500 mL per day is lost as urine in order to rid the body of waste products.
What leads to respiratory acidosis?
Causes of respiratory acidosis include:
Diseases of the airways
, such as asthma and COPD. Diseases of the lung tissue, such as pulmonary fibrosis, which causes scarring and thickening of the lungs. Diseases that can affect the chest, such as scoliosis.
What is the driving force for water intake?
What is the driving force for water intake?
Thirst
.
Where is most water found in the body?
Up to 60% of the human adult body is water. According to H.H. Mitchell, Journal of Biological Chemistry 158,
the brain and heart
are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Which tissues is the least hydrated?
Adipose tissue
is the least hydrated body tissue.
What are the 3 major body fluid compartments?
There are three major fluid compartments;
intravascular, interstitial, and intracellular
. Fluid movement from the intravascular to interstitial and intracellular compartments occurs in the capillaries.
Does water Follow sodium?
Remember that
water always follows sodium
, and you’ll understand why your skin is dry and your urine scant and concentrated when you are dehydrated and conserving sodium. To be sure its supply of salt and water is just right, the body has developed an elaborate series of controls.
Which hormone regulates water level in the human body?
Antidiuretic hormone (ADH)
is a hormone that helps your kidneys manage the amount of water in your body. The ADH test measures how much ADH is in your blood. This test is often combined with other tests to find out what is causing too much or too little of this hormone to be present in the blood.
How is fluid balance maintained in the body?
The kidneys
help maintain electrolyte concentrations by filtering electrolytes and water from blood, returning some to the blood, and excreting any excess into the urine. Thus, the kidneys help maintain a balance between daily consumption and excretion of electrolytes and water.
