1 DO marinate food in the refrigerator, rather than at room temperature. 2  DO marinate in re-sealable plastic bags, rather than in bowls or other containers. 3  They cut down on cleanup and allow you to evenly distribute the marinade. 4  But you can marinate in plastic, stainless steel or glass containers too.
Antidiuretic hormone is secreted from the posterior pituitary; it increases water permeability in the last segment of the distal tubule. Renin stimulates the renin-angiotensin-aldosterone system, which can increase systemic arterial pressure and change renal blood flow.
All of the glomeruli are located in the cortex. The initial segment of a renal tubule is called the proximal convoluted tubuleâ proximal because it is the first segment of renal tubule to receive the filtrate from the glomerulus, and convoluted because it is twisted (Figure 51.9c).All the proximal convoluted tubules are also located in the cortex.At a certain point, the renal tubule takes a dive directly down into the medulla. The portion of the tubule in the medulla is the loop of Henle.ll the proximal convoluted tubules are also located in the cortex.
