Hypertensive kidney disease this situation, the kidney supplied blood by the narrowed renal artery suffers from inadequate blood flow, which in turn causes the size of the kidneys to decrease. Other consequences include arterial stiffening, which involves a gradual breakdown of elastic fibers and intima (the innermost layer of a blood vessel) thickening. An alternative mechanism of hypertensive nephropathy is prolonged glomerular hypertension and hence glomerular hyperfiltration. These can occur simultaneously but not necessarily. The idea is that hypertension results in sclerosis of the glomeruli which ultimately means reduced kidney function. As a compensatory mechanism, the unaffected nephrons (specifically, the preglomerular arterioles) vasodilate
Lateral thoracic artery it supplies an external mammary branch which turns round the free edge of the Pectoralis major and supplies the breasts. Lateral thoracic artery In human anatomy, the lateral thoracic artery (or external mammary artery) is a blood vessel that supplies oxygenated blood to the lateral structures of the thorax and breast. It originates from the axillary artery and follows the lower border of the Pectoralis minor muscle to the side of the chest, supplies the Serratus anterior muscle and the Pectoralis major muscle, and sends branches across the axilla to the axillary lymph nodes and Subscapularis muscle. It anastomoses with
