Arteries may be regarded as fibre-reinforced materials, with the stiffer collagen fibres present in the arterial wall
bearing most of the load during pressurisation.
A recent study published in Thrombosis and Haemostasis found that supplementation with vitamin K2 in the form of MK-7 (menaquinone-7) can help reduce the risk of age-related arterial wall
stiffness in middle-aged women.
From uniaxial tests of arterial wall
, we can see that arterial wall
has the phenomenon of non-linear stress strain relation and having higher extensibility in the low stress and progressively lower with increasing stretch, which is well known also in the framework of rubber-like materials .
According to the wall strain-stiffening phenomenon, high stress sites correspond to stiffer sites in the arterial wall
Laughter reduces arterial wall
stiffness, which researchers suggest may relieve tension.
Coronary artery dissection results from separation of the layers of the arterial wall
creating a false lumen between the intima and media or media and adventitia.
Arteries Insulin can narrow the arteries by stimulating the growth of muscle fibres in the arterial wall
Sildenafil, most commonly known as Viagra, is also used to treat pulmonary arterial hypertension by relaxing the arterial wall
, meaning the workload of the right ventricle is reduced.
Topics include transport/reaction processes in biology and medicine, microvascular heat transfer, animal surrogate systems, arterial wall
mass transport, transport phenomena and the microenvironment, and transport and drug delivery through the blood-brain barrier and cerebrospinal fluid.
Previous studies have shown an association between environmental tobacco smoke (ETS) exposure in adults and cardiovascular disease (CVD) and an increase of the thickening of the arterial wall
and lipid alterations associated with atherosclerosis.
Therefore, while normal cholesterol levels in the arterial wall
are critical for ethanol-induced cerebral vasoconstriction, arterial wall
cholesterol enrichment does not drastically modify ethanol-induced vasoconstriction.
The third and outermost portion of the arterial wall
is called the adventitia.
