The two factors that are regulated to maintain fluid balance in the body is ECF volume and salt balance.
ECF volume is the Extracellular fluid volume. Maintaining the ECF volume is essential to prevent any damage to the body. In severe cases of disbalanced ECF volume, it can also lead to circulatory shock.
Salt balance is essential to be maintained in the body for the proper functioning of all the system of the body. Excess of salts like sodium can cause dehydration. Sodium is the most critical element in the body and its levels should be strictly maintained. Even low salt conditions can lead to fatigue, nausea, weakness, confusion, etc.

4. both stems contain a single-layered epidermis.
<span>1.so first. Amine-derived hormones are derivatives of the amino acids tyrosine and tryptophan. Examples are catecholamines and thyroxine.
2. second. Peptide hormones consist of chains of amino acids. Examples of small peptide hormones are TRH and vasopressin. Peptides composed of scores or hundreds of amino acids are referred to as proteins. Examples of protein hormones include insulin and growth hormone.
3. third. Steroid hormones are derived from cholesterol. The adrenal cortex and the gonads are primary sources. Examples of steroid hormones are testosterone and cortisol. Sterol hormones such as calcitriol are a homologous system.
4. and fourth Lipid and phospholipid hormones are derived from lipids such as linoleic acid and phospholipids such as arachidonic acid. The main class is the eicosanoids, which includes the widely-studied prostaglandins.</span>
