Tubular reabsorption occurs along the renal tubules of the kidneys, explains Dr. Perry Carter of Midlands Technical College. A renal tubule consists of a proximal convoluted tubule, the loop of Henle and distal convoluted tubule. Filtrate from the renal corpuscle drains into the proximal convoluted tubule, where reabsorption immediately begins.Know More
The different segments of the renal tubule have varying reabsorption capabilities, explains Dr. Carter.
The proximal convoluted tubule is the most active section for reabsorption, returning glucose, amino acids, vitamins, water, urea and various electrolytes back to the bloodstream. The descending portion of the loop of Henle continues water reabsorption, while the ascending portion continues electrolyte reabsorption.
The distal convoluted tubule is active in reabsorbing sodium, chlorine and calcium ions. The passing filtrate empties from the renal tubules into the collecting ducts, where additional electrolytes, water and urea are also reabsorbed.Learn more about Human Anatomy
The two phases of digestion are mechanical digestion and chemical digestion, according to Midlands Technical College. Both phases occur in the mouth, stomach and small intestine, but chemical digestion also occurs in the large intestine.Full Answer >
The reabsorption of glucose occurs in the kidneys. Plasma and non-cell parts of the blood enter tubes in the kidneys called nephrons, where waste is filtered out and necessary components, such as glucose, are reabsorbed into the bloodstream.Full Answer >
Obligatory reabsorption of water occurs in the kidneys. The reabsorption of water is a part of the process that the kidneys perform of filtering and returning to the bloodstream about 200 quarts of fluid within a 24-hour period, states the National Kidney Foundation.Full Answer >
As part of the immune system, a primary function of lymphocytes is to respond immediately to the presence of foreign matter, viral attacks and invading pathogens. Lymphocytes, which are a type of white blood cell, are found in the blood and certain lymphoid organs.Full Answer >
