1 Transitions can be at the end of the first paragraph, at the beginning of the second paragraph, or in both places.  Transitions within paragraphs: As with transitions between sections and paragraphs, transitions within paragraphs act as cues by helping readers to anticipate what is coming before they read it.
There are two parts of a kidney nephron: the renal corpuscle, and the renal tubule. (1) Renal Corpuscle. The renal corpuscle is the part of the kidney nephron in which blood plasma is filtered.2) Renal Tubule. The renal tubule is the part of the kidney nephron into which the glomerular filtrate passes after it has reached the Bowman's capsule. The first part of the renal tubule is called the proximal convoluted tubule (PCT) , which is shown on the right-hand side of the diagram above.
1. A nephron consists of a renal corpuscle where fluid is filtered, and a renal tubule into which the filtered fluid passes (Figure 26.5). a. Nephrons perform three basic functions: glomerular filtration, tubular reabsorption, and tubular secretion.
