Does the body adjust its pH by glomerular filtration?
No. The body adjusts its pH through tubular secretion (of H+ ions).
Increased secretion of aldosterone would result in a .... blood ph....?
decrease
What are the two ways in which the kidneys help to maintain homeostasis in the body?
it remove urine and send it to the bladder the kidney is a reabsorbing organ
Explain the mechanism of tubular secretion explain 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
How do the kidneys help to prevent blood pH from rising?
If blood pH is too low (ph < 7.35 ) = acidosis If blood pH is too high (pH > 7.45) = alkalosis In alkalosis: at the intercalated cells of the collecting duct the following occurs: secretion of Hco3- (via Hco3- / cl- antiporters) into the glomerular filtrate, which ultimately forms the urine. Rebsorption of Hydrogen ions (via ATPase dependant proton pumps)
Is tubular secretion effective in controlling blood pH?
True!

No. The body adjusts its pH through tubular secretion (of H+ ions).
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.

decrease
The kidneys help to regulate the PH of body fluids by controlling the?
The kidneys control pH by secreting or reabsorbing H+ ions.
Select the correct statement about the regulation of gastric secretion?
ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.

What might add to or remove from the blood to control its pH?
buffers
When blood pH begins to rise the respiratory control centers in the brain are?
depressed
What happens in there is less secretion of insulin?
High blood sugar (glucose) levels in the blood are the number one reaction to a decrease in insulin secretion.However, lack of insulin secretion over time can also contribute to an individual obtaining Diabetes.Therecan also be spillage of keytones into the urine (which disrupts pH levels in the blood) from lack of insulin. These keytones can contribute to ketoacidosis which can cause coma or even death.Excessive urination and thirst are also effects of lack of insulin secretion due to the raise of blood sugar.
