what happens if too much water is reabsorbed into the blood from the material in the large intestine and the problems this can cause.​

Answers

Answer:

More ADH will be released, which results in water being reabsorbed and small volume of concentrated urine will be produced. If a person has consumed a large volume of water and has not lost much water by sweating, then too much water might be detected in the blood plasma by the hypothalamus.

Explanation:

If too much water is reabsorbed into the blood from the material in the large intestine, it can lead to dehydration.


What is dehydration?

The large intestine is responsible for absorbing water and electrolytes from the indigestible material that remains after digestion in the small intestine. Under normal circumstances, the amount of water that is reabsorbed is carefully regulated to ensure that the body stays hydrated and that the consistency of the stool is appropriate.

However, if too much water is reabsorbed, it can lead to dehydration, which can cause a variety of symptoms and problems. These may include:

Dry mouth and thirstDark yellow urineDry skinHeadachesFatigueConstipationDizziness or lightheadednessIncreased heart rate

Dehydration can be caused by a variety of factors, including not drinking enough fluids, sweating excessively, or having diarrhea. It is important to drink enough fluids and replace lost electrolytes to prevent dehydration. In severe cases, dehydration may require medical treatment.

Explanation:

I picked habitat planner and land planner to do because I am an artist and a designer and I know how to put things together properly and for people to be like "Wow this is a beautiful piece right here" I would make it beautiful for the person's eyes when doing this you need to think about how a person might look at it I would want them to gasp and stare astonished and amazing and I could do that I've been practicing design for awhile now so If I were to pick these two things it is what I would do and also I really like nature and designing things with nature that others haven't thought about because it shows my creativity and ability to look beyond the point of just seeing.

If I could choose any career in ecology, I would pursue a career as a habitat planner.

This profession would allow me to contribute to the conservation and restoration of natural habitats, ensuring the well-being of various species and ecosystems. As a habitat planner, I would have the opportunity to assess existing habitats, develop conservation strategies, and collaborate with stakeholders to implement effective management plans.

I am passionate about the preservation of biodiversity and creating sustainable environments, and this career would allow me to make a tangible impact on the natural world.
