Mealworms, like other animals, take in oxygen and release carbon dioxide during respiration.

During respiration, animals take oxygen from the air and release waste gas, carbon dioxide.

Oxygen is essential for respiration, a process that produces energy in living organisms, including mealworms

Carbon dioxide is a waste product released from animals during respiration as a result of converting energy from food.

Inhaled air has higher oxygen and lower carbon dioxide content compared to exhaled air.

When oxygen is consumed, the gas pressure in a contained space decreases.

Experimental process for comparing oxygen and carbon dioxide in inhaled and exhaled air.

Human beings, like mealworms, exchange gases (oxygen and carbon dioxide) with the outside air.

The time it takes for a candle flame to extinguish in a jar of inhaled air versus exhaled air. This shows the oxygen levels in different types of air.

Inhaled air has more oxygen than exhaled air.

Exhaled air has less oxygen than inhaled air.

Exhaled air contains more carbon dioxide than inhaled air.

A chemical that changes color in the presence of carbon dioxide.

A test to determine the carbon dioxide content of exhaled air using hydrogencarbonate indicator.

A test to determine the carbon dioxide content of inhaled air using hydrogencarbonate indicator.

Oxygen is essential for a substance to burn (combustion).

A chemical indicator used in experiments to detect the presence of water vapor. It turns from blue to pink when exposed to moisture.

Cobalt chloride paper that has not been exposed to moisture and remains blue in color.

Exhaling warm, moist air onto a mirror surface, causing condensation to form due to the presence of water vapor.

Using cobalt chloride paper to detect the amount of water vapor present on a mirror surface.

The change in color of cobalt chloride paper from blue to pink indicates the presence of water vapor.

Exhaled air contains more water vapor because our bodies produce water vapor as a byproduct of respiration.

The cobalt chloride paper turns pink because the exhaled air contains more water vapor than the air.

To ensure accurate results, the mirror should be clean to avoid contamination from previous experiments.

Approximately 8 million people die worldwide annually due to diseases caused by smoking.

Diseases affecting the lungs, including bronchitis and lung cancer, are often linked to smoking.

Smoking contributes to a significant number of deaths worldwide, mostly from smoking-related diseases.

Smoking increases the risk of developing respiratory diseases like bronchitis and lung cancer.

A serious disease affecting the lungs, often caused by smoking.

An inflammation of the airways in the lungs, often triggered by smoking.

Cancer affecting the mouth area, linked to smoking and other factors.

A serious medical condition affecting the brain, which can be linked to smoking.

Two smaller tubes that branch off from the trachea, carrying air into the lungs.

Tiny tubes that branch off from the bronchi, further dividing the airflow within the lungs.

Tiny, balloon-like structures at the ends of bronchioles in the lungs, where oxygen is exchanged with the blood.

Air flows from nostrils, through the nasal cavity, trachea, bronchi, bronchioles, and finally into the air sacs in the lungs.

Capillaries are tiny blood vessels surrounding air sacs, facilitating the exchange of oxygen and carbon dioxide between the air and blood.

Air sacs are the primary sites for gas exchange in the lungs, where oxygen passes into the bloodstream and carbon dioxide is released.

Bronchioles are small tubes that lead to air sacs. The air sacs cluster at the ends of the bronchioles, creating a large surface area for gas exchange.

The respiratory system is responsible for taking in oxygen, which is essential for energy production in the body, and releasing waste carbon dioxide.

The process where animals take in oxygen from the air and release carbon dioxide as a waste product.

When we breathe in, air travels through the nose, trachea, bronchi, and bronchioles to the alveoli in the lungs. When we breathe out, it travels in reverse.

In the lungs, oxygen from the inhaled air moves into the bloodstream, and carbon dioxide from the blood moves into the air to be exhaled.

Tiny air sacs called alveoli in the lungs are where the exchange of oxygen and carbon dioxide between the air and blood takes place.

A candle flame needs oxygen to burn. It will extinguish faster in a container of exhaled air because it has less oxygen.

Using hydrogencarbonate indicator, we can demonstrate the presence of more carbon dioxide in exhaled air compared to inhaled air.
