So, I know you get a portion of your daily water intake from food, but how does your body decide how to seperate it out? What part of the digestive process does this occur in?
In: Biology
A majority of the absorption of nutrients and water from our food happens in the small intestine, with a last-minute check happening in the large intestine. Whatever our body doesn’t absorb from the intestines keeps moving along and exits the body as feces. The vitamins, nutrients and water absorbed through the intestines are moved to the bloodstream.
As your blood circulates your body it moves along essential life ingredients to our cells, but it also collects all the waste our cells produce as a byproduct. In order to stay healthy our blood is sent through a filtration device called our kidneys. All of the blood in our body eventually gets to our kidneys for a good clean. Kidneys clean blood like we’re cleaning the fridge. They take everything out then put back what you need. This happens in what is called a nephron. The nephron is able to control how much liquid is in your blood (and therefore control your blood pressure) by monitoring sodium (salt) content in the body. If you’re high in sodium your kidneys will keep more water. Everything your body didn’t need to put back in the fridge (waste products and excess water) then travels along a series of tubes through your kidneys, into your bladder and then leaves the body as urine.
