Received 2 liters of normal saline does hematocrit increase?

Biology

The saline distributes rapidly (within about 15 minutes) from the intravascular to the interstitial compartment. And there, it is stuck.

The cells have active pumps and the membrane is impermeable to sodium; similarly, chloride is trapped.
Because normal saline is isoosmotic with the extracellular fluid, water does not have any osmotic pressure to shift between compartments, and it distributes itself according to the proportional distribution of sodium (i.e. about 25% of it stays intravascular and 75% enters the interstitial fluid).

(This may not be entirely accurate. Because the osmolality of the extracellular fluid increases, some water undegoes a shift into the extracellular compartment. The new equilibrium point is 290.2 mOsm/L. To achieve this, a whole 25ml of water has to move up into the extracellular compartment. So, the intravascular volume increases not by 250ml, but by... 256ml. What a big difference that makes. In order to remain detached from pedantic hair-splitting, I have opted to omit this from all the further calculations.)

Plasma osmolality doesn't change much, because it has received a load of essentially isoosmolar fluid.
<span>You will notice that the osmolality of the compartments increases by 0.2 mmol/L from your maths; but the osmoreceptors dont care.</span>

15,000 years ago, when humans were foragers and hunters, what characterized daily life? What were humans eating, and where and h
lisabon 2012 [21]

1. 15,000 years ago the humans were still hunter-gatherers. Their daily lives were largely based around one thing, finding enough food to survive through  the next few days. This means that they had to constantly be on the move, be it for hunting animals, or for finding rich places with eatable plants. There was lot of walking, running, and scouting involved every day. It was a lifestyle of ''living through the day''.

2. During this period of time, the diet of the humans was consisted of animals they hunted, fish, and plants. There were differences from region to region though, so the people that lived along the coastline based their diet on marine animals, the ones that were living in colder regions were eating mostly meat, while the ones living in forested areas or grasslands had combination of plants and meat. The lifestyle in general was moving from place to place, be it on a daily basis, weakly, or seasonally, depending on the conditions. Some of these people were making small shelters, some of which were retractable and they were moving them with them, while others were using caves.

3. There are many difference between the forager peoples and the agriculturalists. The foragers were nomads, thus they were moving very often from one place to another, while the agriculturalists were having a settled lifestyle. The nomads very often had bad injuries which were often fatal, usually because of hunting, while the agriculturalists had much better health because they had much safer lifestyle. The foragers were not able to produce their own food, but instead they were relying on mother nature, while the agriculturalists were producing their own food and had the food problem solved.

C) Natural selection

When something happens in nature and something changes all of a sudden, the animals tend to adapt to what gives them more chances of survival.  As a result, a large amount of the population would attempt to adapt in a way that helps them survive.
