macula for static equilibrium and cristae for dynamic equilibrium. All are found in the inner ear.
The Macula is the receptor for static equilibrium.

The M2 muscarinic acetylcholine receptor is the primary receptor found in effector organs of the parasympathetic system. Activation of this receptor leads to inhibition of adenylate cyclase and decreased intracellular levels of cyclic AMP, resulting in various physiological responses in target tissues.
The sensory receptor for static equilibrium is the vestibule located in the inner ear. The vestibule contains two structures called the utricle and saccule, which detect changes in head position and orientation to help maintain balance.

An organ that contains receptor cells is called a sensory organ. These organs perceive external stimuli such as light, sound, touch, taste, and smell and transmit this information to the brain for processing.
The lungs and the kidneys are two organs that respond to changes in blood buffer equilibrium. The lungs regulate carbon dioxide levels by adjusting breathing rate, while the kidneys control bicarbonate levels through filtration and reabsorption. Together, they help maintain the blood's pH balance.
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
