Diuretics help people to eliminate excess fluid and increase urine output. Medications such as furosemide (brand name Lasix) or hydrochlorothiazide are commonly used examples.
The tissues get oxygen from oxygenated blood supply for energy production.
reduced osmotic return of fluid and thus accumulation of fluid in the tissues resulting in edema
Meristem cells are responsible for the production of tissues and organs. They have a lifelong ability to do so.
The answer is quite simple. To have a high rate of respiration requires a high blood flow to distribute the oxygen to the tissues. Increasing heart rate is one means of increasing the blood flow to the tissues. The other means in increasing the amount of blood that is from the left ventricle with each contraction.
