What relationship will water volume have on blood pressure?

Changes in blood volume affect arterial pressure by changing cardiac output. An increase in blood volume increases central venous pressure. This increases right atrial pressure, right ventricular end-diastolic pressure and volume.

Blood is mostly made up of water. If you're dehydrated you will have a lower blood volume. A lower blood volume will decrease the amount of blood pressure. Just imagine filling a closed container with gas or liquid and you should be able to understand the relationship between volume and pressure.

Lightheadedness can be caused by low blood pressure because their is not enough blood getting to your brain. High blood pressure would give you a headache due to the pressure exerted on your brain.

Low urine output is due to your body's response to low levels of water and blood volume. The higher the blood and water volume, the more hormones that are released to signal your kidneys to get rid of water. And the opposite goes for low blood volume.

The reason your urine is dark could be caused by a lot of things, but in this case it could be caused by low amounts of water to dilute it.

Hope this helps you understand whats going on and how one thing can cause multiple things to happen in your body.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
