Each villus has its own blood supply to maximize absorption of nutrients from the small intestine. This allows for efficient exchange of substances between the villi and blood vessels, optimizing nutrient uptake from digested food. Having individual blood supplies also helps maintain a concentration gradient for effective absorption.
The medical term for tissues without their own blood supply is avascular tissue. These tissues rely on diffusion to obtain nutrients and oxygen from nearby blood vessels. Examples include cartilage and cornea.
Fraternal twins do not share the same placenta in the womb, so they do not share the same blood supply or amniotic sac. This means that they do not have the same germs. Each twin has their own unique immune system and biological makeup.
Pulmonary circulation = between the heart and the lungs Coronary circulation = the heart tissue's own blood supply Systematic circulation = between the heart and the rest of the body
In most cases, each household is connected to a public water supply system that serves multiple households. However, in some remote or rural areas, households may have their own private water supply from wells, boreholes, or rainwater harvesting systems.
Cartilage is avascular, meaning no blood supply. This is why cartilage is so long to heal and most often irreplaceable if damaged severely enough. The epidermis and subcutaneous connective tissues are vascular.
The epidermis.

The heart muscle that has its own supply of blood from vessels is called the myocardium. It receives its blood supply primarily through the coronary arteries, which branch off from the aorta. This blood supply is crucial for delivering oxygen and nutrients to the heart muscle, enabling it to function effectively.
the process through which the tumor supports its growth by creating its own blood supply is called angiogenesis

That has never come in to question as you cant "reserve" your own blood. Blood banks are open
No, but a good guess. They are called the coronaries.
Coronary arteries supply blood to the heart itself.
The subcutaneous layer.
The heart has its' own blood supply by way of the coronary system.
