Answer:

If red blood cells are placed in a hypertonic solution, they will shrink because the water moves out of the cell through osmosis. When red blood cells are places in hypotonic solution they swell and rupture because the water moved in the cell through osmosis.

Explanation:

If red blood cells are placed in 1400mOsm of NaCl, the cell volume will be lost because the wayer in the cell moves out due to higher concentration of salt outside, they will shrink.

Similarly if the red blood cells are places in urea and NaCl the cell will again shrink.

raketka [301]

The statement would that the nurse would utilize is that it allows the patient to breathe on his own while he can receive a preset number of breaths from the ventilator.

He/she can breathe as much or as little as he wants beyond what the ventilator will breathe for him.

SIMV stands for synchronized intermittent mandatory ventilation.

can say a more of control form of ventilation.

With the help of SIMV, we set the rate, set either volume or pressure, and add in pressure support.

The role of SIMV is that it provides additional inspiratory pressure which doesn't let the patient work hard and also enable better oxygenation and a speedy recovery.

using SIMV is not a piece of cake, this can be a challenge to understand, as it is usually a combination of control, assisted and spontaneous breaths and to check it requires skills.

What is the mechanism by which the kidney forms a dilute urine? What is the mechanism by which the kidney forms a concentrated u
Whitepunk [10]

Answer:

The mechanism of by which kidney forms dilute or concentrated urine is based on the amount of ADH( Antidiuretic hormone) present in the blood. Collecting duct have receptors for the binding of ADH hormone.

Formation of concentrated Urine:                                                        

When the ADH hormone binds to the receptors present on the cells of collecting duct it open the water channels present on it. Once the water channel is opened the duct becomes permeable to water and reabsorption of water takes place in the body making urine concentrated.

Formation of diluted urine:                                                                    

When ADH is not secreted in the blood, the collecting duct remains impermeable to water molecules which results in production of diluted urine. This happens when blood contains sufficient water.
