It is composed of a renal corpuscle and a renal tubule. The English version serves two purposes: as a learning aid for international students and to encourage Germanspeaking -. Relationships among the vascular beds • Flow is constant in each segment, so velocity and area are inversely related • Pressure loss occurs mainly at the small arterioles, the resistance vessels. renal hemodynamics (28). Increased arteriole pressure stretches the blood vessels, which causes reflex contraction of the smooth muscle in the blood vessel walls and increased resistance to blood flow - stretch activated Ca+2 channels allow more Ca+2 into cell and increases tension in smooth muscle (increased resistance) - increased resistance balances increased pressure. There are two broad classifications of hypertension and these are essential and secondary. Snell "for their discoveries concerning genetically determined structures on the cell surface that regulate immunological reactions". When food is taken, it is broken down into smaller components.
