Both urinary system and digestive system works to conserve water in the human body by way of shutting off the flushing of water when the body is being dehydrated and water is needed to remain in the body.
The body has receptors whereby the receptors estimates the amount of water in the cells and in blood. Receptors sends the information to the brain through the neurons.
All liquids are being absorbed and put in the bloodstream through the digestive system. It is through the bloodstream where water is being spread to all other body parts then cells absorbs it.
Electrolytes and water are reabsorbed and filtered when the blood which passes to the other parts of the body goes to the kidney.
If there is low circulation of liquids in the body, and the brain gets the signals it activates hormones which then influences both urinary system and digestive system.
Everything that we eat and drink contains some percentage of water. So, to start, you have to know that the human body has receptors which estimate if we have enough water in our blood and cells in general. From these receptors, the information travels through the neurons to the part of the brain that is responsible for activation of different responses.
The digestive system is important because in its lower parts, liquids are absorbed and inserted in the bloodstream. Then through the bloodstream, they travel to all parts of the body and are absorbed by cells as needed. When blood passes through the body, it gets to the kidneys where water and electrolytes are filtered, reabsorbed if needed and excreted through the urine.
Now, if the brain has a signal that the body has a lack of liquids, it activates hormones which influence the bloodstream in both the digestive and the urinary system. In this case, the digestive system will absorb more liquids from food because the hormones will make the blood vessels in the digestive area larger, and on the other hand, we will produce less urine because the kidneys will get an assignment from the brain to filter liquids, but to reabsorb them again as much as possible.
False. Evaporation is a physical change it is not a chemical change. It is a physical change because it is going from the liquid phase to the gas phase. It is not a chemical change because it is still made of two hydrogen atoms and an oxygen atom.
Activational effect is an impermanent hormonal effect that leads to a change in physiological activity or behavior in both humans and adult animals. For instance, when testosterone levels rise in male songbirds they become more aggressive and tend to engage in courtship behavior. Also, a pregnant woman may get more emotional than usual due to an extra level of progesterone and estrogen during pregnancy.
