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.
A third part of the nephron is a collecting duct that drains urine from the tubule. Each tubule has three interconnected parts: the proximal convoluted tubule, the loop of Henle, and the distal convoluted tubule. The kidneys consist of an outer part (cortex) and an inner part (medulla). All glomeruli are located in the cortex, while tubules are located in both the cortex and the medulla. The urine drains from the collecting ducts of many thousands of nephrons into a cuplike structure (calix). Each kidney has several calices, all of which drain into a single central chamber (renal pelvis).
