$\bf\pink{perfusion :}$

Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue,[1] usually referring to the delivery of blood to a capillary bed in tissue. Perfusion is measured as the rate at which blood is delivered to tissue,[2] or volume of blood per unit time (blood flow) per unit tissue mass. The SI unit is m3/(s·kg)[citation needed], although for human organs perfusion is typically reported in ml/min/g.

✦ discovery :

In 1920, August Krogh was awarded the Nobel Prize in Physiology or Medicine for his discovering the mechanism of regulation of capillaries in skeletal muscle.[6][7] Krogh was the first to describe the adaptation of blood perfusion in muscle and other organs according to demands through the opening and closing of arterioles and capillaries.[

✦ measurements:

In equations, the symbol Q is sometimes used to represent perfusion when referring to cardiac output. However, this terminology can be a source of confusion since both cardiac output and the symbol Q refer to flow (volume per unit time, for example, L/min), whereas perfusion is measured as flow per unit tissue mass

Answer 2

$\large\rm\red \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: Perfusion$

Perfusion can be defined as the process in which blood is forced to flow through a network of microscopic vessels within biologic tissue, allowing exchange of oxygen and other molecules across semipermeable microvascular walls.
