Nephron
kidney
Aldosterone acts on the distal convoluted tubule and collecting duct in the kidney to increase sodium reabsorption and potassium secretion.
The regulation of pH of the filtrate is what occurs in the proximal tubule. The regulation occurs by exchanging hydrogen ions for bicarbonate ions. The proximal tubule is part of the duct system of the kidney.
The tube after the Bowman's capsule in the kidney is the proximal convoluted tubule (PCT). This tubule is responsible for reabsorbing water, electrolytes, and nutrients from the filtrate back into the bloodstream.
Nephron is the basic structural and functional unit of the kidney. https://en.wikipedia.org/wiki/Nephron It is composed of a renal corpuscle and a renal tubule. The renal corpuscle consists of a glomerulus and the Bowman's capsule. It is the nephron's initial filtering component. The components of the renal tubule are the proximal convoluted tubule, loop of Henle and the distal convoluted tubule.
This is in the kidney and it mainly controls how much or little water is kept in the body
Nephron
Each one consists of a renal corpuscle and a renal tubule which carry out the functions of the nephron. The renal tubule consists of the convoluted tubule and the loop of Heinle http://coe.fgcu.edu/Faculty/GreeneP/kidney/nephron.html.
The distal tubule
Proximal convoluted tubule
The renal medulla contains collecting ducts.
Mitochondria are abundant in kidney tubule cells due to their high energy demands for active transport and metabolic processes involved in regulating fluid and electrolyte balance. Mitochondria generate ATP through aerobic respiration to fuel these energy-demanding cellular functions in kidney tubule cells.
