Name the process by which molecules move from the proximal convoluted tubule into the blood?
Tubular reabsorption
Is the net direction of tubular secretion into or out of the blood?
into
Is tubular secretion effective in controlling blood pH?
True!
The process that transports substances out of the tubular fluid and back into the blood of the peritubular capillary is known as?
Tubular secretion
Excess hydrogen ions are removed from the blood by tubular secretion?
True
What is Active transport of substances from the blood into the nephron called?
Tubular secretion
The active transport of penicillin from the blood into the nephron is an example of the process of?
tubular secretion
Where is the primary site at which tubular secretion occur?
Tubular secretion is a part of urine formation occurring within the nephrons of the kidneys. After glomerular filtration, in which fluids from the blood pass into the glomerular capsule of the renal tubule, the filtrate is subject to tubular reabsorption and tubular secretion within the convoluted tubules and collecting ducts of the nephrons.
The process by which the renal tubule actively moves substances from the blood into the nephron to be excreted?
Tubular secretion
Explain the mechanism of tubular secretion and its importance in the urine formation process?
"Tubular secretion is the reverse process of tubular reabsorption. Substances such as hydrogen and potassium ions and creatinine move either from the blood of the peritubular capillaries through the tubular cells or from the tubular cells into the filtrate to be disposed of in the urine. This process is important for the disposal of substances not ready in the filtrate and as a device for controlling blood pH" Page 615 in Human Anatomy & Physiology Laboratory Manual
What are the three steps of urine formation and in what part of the nephron does each occur?
Urine formation and the adjustment of blood composition involve three major processes: glomerular filtration by the glomeruli, and tubular reabsorption and tubular secretion in the renal tubules. In addition, the collecting ducts work in concert with the nephrons to concentrate or dilute the urine..Functions of the nephrons include filtration, tubular reabsorption, and tubular secretion. Via these functional processes, the kidneys regulate the volume, composition, and pH of the blood, and eliminate nitrogenous metabolic wastes.
Define tubular secretion?
