Auto regulation (intrinsic) is when a cell, organ, or organ system automatically adjusts itself in response to a change in the environment. Extrinsic regulation involves the nervous and/or endocrine system detecting a change and sending a signal or releasing a chemical to facilitate change in another organ system, organ, or cell.
Extrinsic
Those semiconductors in which some impurity atoms are embedded are known as extrinsic semiconductors.

at higher values of temperature the intrinsic carrier concentration become comparable to or greater than doping concentration in extrinsic semiconductors. thus majority and minority carrier concentration increases with increase in temperature and it behaves like intrinsic semiconductor.
Extrinsic regulation
The three primary mechanisms for controlling vessel radius are neural regulation (via sympathetic and parasympathetic nerves), local regulation (autoregulation in response to changes in local factors like oxygen levels), and hormonal regulation (via hormones like adrenaline and angiotensin II).

Autoregulation is a specific form of homeostasis used to describe the tendency of the body to keep blood flow constant when blood pressure varies.[1]. While most systems of the body show some degree of autoregulation, it is most clearly observed in the kidney, the heart, and the brain.[2] Perfusion of these organs (especially the latter two) is essential for life, and through autoregulation the body can divert blood (and thus, oxygen) where it is most needed. One key component of autoregulation is the absence of central control. The "auto" in autoregulation refers to the ability of the organ to maintain a stable flow without the involvement of the autonomic nervous system.
The extrinsic regulation of glomerular filtration rate (GFR) involves the autonomic nervous system and the renin-angiotensin-aldosterone system. The sympathetic nervous system can constrict renal blood vessels, reducing GFR, while the renin-angiotensin-aldosterone system can regulate blood pressure and volume, affecting GFR. These mechanisms help maintain a balance between filtration and reabsorption in the kidneys based on the body's needs.
No, the adjustment of blood flow to each tissue in proportion to its requirements at any point in time is termed tissue autoregulation. Autoregulation refers to the ability of an organ or tissue to regulate its own blood flow independent of systemic factors.
