Radial Artery
The radial artery
The lateral side of the hand receives blood supply from the radial artery.
Blood vessel radius has a larger effect on the body because changes in radius significantly impact blood flow resistance, which affects blood pressure regulation and delivery of oxygen and nutrients to tissues. Vessel length, on the other hand, has a smaller direct effect on blood flow resistance and overall cardiovascular function.
The radial pulse is checked for vital signs.
the brachial vein receives blood for the ulnar and radial veins.
If you increase the radius of a blood vessel, the flow rate of blood through that vessel will increase significantly. This is due to the principles of fluid dynamics, specifically Poiseuille's law, which states that flow rate is proportional to the fourth power of the radius. As the radius increases, resistance to flow decreases, allowing more blood to flow through the vessel with less pressure required. Consequently, a larger radius enhances overall blood circulation in the body.
The radial artery is located on the thumb side of the forearm. It is a major blood vessel that supplies the forearm and hand with oxygenated blood.
carotid arteries
Subclavian artey becomes axillary artery. Axillary artery becomes brachial artery. Brachial artery divides into radial and ulnar branches. You palpate radial artery at distal end of radius bone. So you feel a pulse betwwen radius and your fingers. So it is better felt than ulnar artery.
Radius. Length only changes with weight loss, gain or while one is growing. (from infancy to adult)
To provide the heart with a blood supply.
The relationship between blood flow through a vessel and the radius of the vessel can be expressed as BF=1/pi r4 (where pi is equal to 3.14.....). So a change in the radius of a vessel has a large effect on the blood flow through the vessel.
