The body loses water in a variety of ways. Put the water output mechanisms in order from greatest contribution to fluid loss (1)
kirza4 [7]

The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces

<h3>What are the ways in which body loses water ?</h3>

Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.

The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.

Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.

When acetylcholine binds to receptors at the motor end plate, the end plate membrane becames:__________a. repolarized. b. more p
sladkih [1.3K]

Answer:

d. more permeable to sodium ions.

Explanation:

The binding of Acetylcholine  with the receptors at  motor end plate facilitate   membrane permeability to sodium ions therefore  opening of voltage gated channels for sodium ions.

Sodium ions diffused into the synapse of post synaptic neuron at the neuromuscular junction.

If  the  stimulus is up to threshold levels; more chemical(neurotransmitter) gated sodium channels opens, and sodium ions move into the  synapse to depolarize the membrane with  reversal of charges to generate action potential.

The continuous  binding of Acetycholine , leads to permanent opening of sodium ions,and over excitation from depolarization.  Acetycholinesterase enzymes breakdown Acetycholine to choline  and Acetyl Co -A. These are recycle back to Acetycholiine
