Explanation

In humans and higher animals, the exchange of gases (oxygen and carbon dioxide) is carried out by the respiratory processes, which include:

• Breathing (inhalation and exhalation)
• Transport of gases through the blood
• Exchange of gases in the lungs (oxygen in, carbon dioxide out)

Explanation

Respiration involves two main processes:

1. Mechanical Process (Ventilation):

• Breathing in (inhalation)
• Breathing out (exhalation)
• Movement of air in and out of the lungs

2. Biochemical Process (Respiratory Exchange):

• Exchange of oxygen and carbon dioxide between the lungs and blood
• Transport of oxygen and carbon dioxide through the bloodstream
• Cellular respiration (cellular metabolism)

Explanation

• The lungs are the organs responsible for exchanging oxygen and carbon dioxide through the process of respiration.
• They consist of air-carrying tubes (bronchi and bronchioles) and tiny sacs (alveoli) where gas exchange occurs.

Explanation

• The ozone layer is a layer of gas in the stratosphere that contains a high concentration of ozone (O3).
• It absorbs most of the sun's ultraviolet (UV) radiation, protecting the Earth from harmful UV rays.

Explanation

We can measure our blood pressure on our own using a digital blood pressure monitor for automated readings or an instrument called a sphygmomanometer for manual readings.

A sphygmomanometer also known as a blood pressure monitor, is a device used to measure blood pressure.

Explanation

Hydrochloric acid (HCl) reacts with Sodium hydroxide (NaOH) to form Sodium chloride (NaCl) and Water (H₂O) — a typical acid-base neutralization reaction.

The balanced equation is:

NaOH + HCl → NaCl + H₂O
