Exam 14: Fluid and Acidbase Balance

The barrier between the ECF and the ICF is the ____________________.

A person with diarrhoea loses excessive salt and water from the body. This loss results in Na⁺ depletion, dehydration, a decreased extracellular fluid volume, a reduction in plasma volume, and a decreased systemic arterial blood pressure.The following refer to the events that occur to compensate for this fluid loss. Match the effects, labelled a. through c., with the factors listed. (Options may be used more than once or not at all.) -urinary volume

Which of these actions would be triggered by a drop in arterial blood pressure

Match the imbalances, labelled a. through d., with the descriptions. (Options may be used more than once or not at all.) -Water enters the cells by osmosis.

The force responsible for movement of H₂O a.between the ECF and the ICF is ____________________.

Which of these statements does NOT describe a chemical buffer system

The second line of defence will be the respiratory mechanism of pH control.Which statement describes the respiratory response in this situation

The total load of ____________________ determines the total amount of water that will be retained in the ECF by osmosis.

Which of the following is NOT a source of water input

A person with diarrhoea loses excessive salt and water from the body. This loss results in Na⁺ depletion, dehydration, a decreased extracellular fluid volume, a reduction in plasma volume, and a decreased systemic arterial blood pressure.The following refer to the events that occur to compensate for this fluid loss. Match the effects, labelled a. through c., with the factors listed. (Options may be used more than once or not at all.) -vasopressin secretion

The kidneys are the first line of defence against changes in acid-base balance because they are the most powerful mechanism for maintaining pH.

Bicarbonate ions can combine with free H⁺, removing a source of acidity and opposing acidosis.

Acidosis leads to ____________________ secretion of H⁺ in the urine.

Which of these statements does NOT apply to an individual who is overhydrated

The blood plasma and ____________________ make up the ECF.

HCl is an example of an acid.

A(n) ____________________ is a substance that can combine with a free H⁺, thus removing it from solution.

Which of these statements does NOT refer to extracellular fluid

The pH of venous blood is usually about ____________________.

A pH of less than 6.8 or greater than 8.0 is not compatible with life.
