Yes.
Go with answer B. Lack of fluid in the body will cause dehydration.
The proportion of fluid in the body decreases with age due to factors such as decrease in muscle mass and increase in body fat. This results in a lower percentage of water in the body as we age. Older adults are more prone to dehydration due to these changes in body composition.
Yes, severe dehydration causes urine volume to decrease. Your body will conserve water to maintain homeostasis.
Mild dehydration is the loss of no more than 5% of the body's fluid
dehydration is the excessive loss of fluid in the body of an organism
Cardiac output typically decreases during dehydration. When fluid levels are low, there is less circulating blood volume, leading to a decrease in the amount of blood pumped out by the heart per minute. This reduction in cardiac output helps conserve remaining fluids in the body.
The major stimulus for the thirst mechanism is dehydration, which is when there is a decrease in fluid volume within the body. When the body detects dehydration, it signals the brain to activate the thirst mechanism, prompting the individual to drink fluids to restore proper hydration levels.
Dehydration is serious because the body is composed of mostly water. When you don't have enough, you can jeopardize how the body functions.
Dehydration leads to three main responses. First receptors in mouth detect dryness and stimulates thirst mechanism making you want to drink water. secondly, low blood volume causes decrease blood flow to kidneys resulting in dercrease glomerular filtration rate. this causes body to respond by decreasing quantity of water in urine (ADH) thirdly, you will have low blood pressure and this will be detected by baroreceptors and they will bring up the pressure by means of vasoconstriction.

Dehydration is a process that occurs in the body (and elswhwere). It is not a body system. There are nine (9) body systems, and to remember them remember the following: RED RUM CIN, as in: Respiratory, Endocrine, Digestive, Reproductive, Urinary, Musculoskeletal, Circulatory, Integumentary (skin), and Nervous.
Yes. Urine is intravascular fluid. That said the body can crenate cells to create intravascular fluid from intracellular fluid. This usually is short term but common in chronic dehydration. Elevated K+ in a malnourished person is hallmark of cellular dehydration.
