Respiratory Physiology and Acid-Base Balance Quiz

The movement of a substance from a region of higher concentration to a region of lower concentration.

The process of gas exchange in the lungs, where oxygen moves from the alveoli into the blood and carbon dioxide moves from the blood into the alveoli.

Cells in the lungs responsible for producing surfactant, a substance that helps keep the alveoli open.

A substance that reduces surface tension in the alveoli, preventing them from collapsing.

The tiny air sacs in the lungs where gas exchange occurs.

An increase in breathing rate to expel more carbon dioxide from the body, thereby reducing acidity in the blood.

A state where the blood becomes excessively acidic due to an imbalance in hydrogen ions (H+).

A compound produced in the body as a byproduct of metabolism, which can contribute to blood acidity.

A chemical species that determines the acidity or alkalinity of a solution.

The body's natural response to acidosis, aimed at restoring balance by removing excess carbon dioxide through increased breathing.

A state where the body's response to a substance is overwhelming, and it can lead to serious complications or even death.

Increased intracranial pressure, or ICP, is a condition where there is too much pressure inside the skull.

The kidneys are organs that filter waste from the blood and produce urine.

Feeling the chest and spaces between the ribs for tenderness, unevenness, bulging, and inward pulling.

The spaces between the ribs.

The body's response to an acidic state, aiming to neutralize the excess acid.

A lower-than-normal PaCO3 level, indicating a more alkaline condition.

A measure of acidity or alkalinity in the blood, where 30 is considered basic.

The process of breathing out excess carbon dioxide, contributing to lowering the acidity of the blood.

The body's internal balance, specifically the pH balance of the blood.

The process of identifying whether an acid-base imbalance is caused by problems with the respiratory system or metabolism.

Evaluating the pH value of blood to determine if the imbalance is respiratory or metabolic.

A state where the blood becomes too alkaline (pH higher than 7.45).

A system that maintains the body's pH balance by regulating the removal of CO2 and hydrogen ions (H+).

A substance that helps regulate the pH of the blood by neutralizing excess acid.

The process of maintaining a stable pH in the blood.

The body's ability to adjust to a change in pH by using mechanisms like breathing, kidney function, and buffering systems.

The state when the body is not actively trying to restore normal pH levels, indicating a possible underlying problem.
