strangulated hernia
Strangulated
When a portion of the intestine becomes constricted inside a hernia, it can lead to a condition known as strangulation. This occurs when the blood supply to that part of the intestine is cut off, which can result in tissue death (necrosis) if not addressed promptly. Strangulated hernias are considered a surgical emergency, as they can lead to severe complications like infection, sepsis, and perforation of the intestine. Immediate medical intervention is necessary to restore blood flow and remove any necrotic tissue.
If you cut off circulation you are cutting off the blood supply which will cut off all oxygen as well and the limb will start to die.
I'm not certain but I believe that when you cut of the blood supply to a body part, the blood no longer gets pumped in and out of the area. The colour of blood without oxygen is purple. I believe that they turn purple because the blood supply has been cut and what blood is there has had all its oxygen absorbed. Due to the colour, it probably shows up through the skin easier.
These cells no longer can get nutrients and are cut off from a blood supply.
I assume you are talking about its nails. Well, nothing really, but next time, look for the blood supply and only cut it close, then the blood supply (the quick) will recede, allowing you to cut more. Sort of like people nails.
The uterus is a muscle. During menses it contracts to expel menstrual blood. This is a mild from of the contraction it does to push out a baby. The contraction can press against a blood vessel and cut off the blood supply. This pinching off of the blood supply causes the cramping.
The liver and kidneys are examples of organs that have dual blood supply. They receive blood from both the hepatic portal system and the hepatic artery (liver) and from the renal artery and renal vein (kidneys). This dual blood supply is important for their functions in filtering and processing blood.
if the blood supply is severely reduced or cut off what occurs
If it's to tight then you will cut off the blood flow to that limb. If the blood supply is cut off for long enough then you will most likely end up loosing that limb. The doctors will not be able to save it.
When the blood supply to a herniated structure is cut off, it can lead to ischemia (lack of oxygen), tissue damage, and possibly necrosis (cell death). This situation can cause severe pain and worsen the herniation symptoms. It is considered a medical emergency and requires immediate attention.
If blood supply to an organ is cut off, it can lead to tissue damage and cell death due to lack of oxygen and nutrients. This condition is known as ischemia. If left untreated, it can result in serious consequences such as organ failure or tissue necrosis. Treatment usually involves restoring blood flow to the affected organ as quickly as possible.
