Chapter: 02. The Human Body

⁠

Question 1

⁠

Which sense organ is the child primarily using in this picture?

What is the main function of this sense organ?

Name two other sense organs and describe one function for each.

The child is primarily using their nose in this picture to smell the rose.

The main function of the nose is to detect and perceive different smells from our surroundings.

Two other sense organs are eyes (which help us to see and observe the world around us) and ears (which help us to hear sounds).

Question 2

⁠

Identify the four internal organs that are clearly visible in this diagram.

Which of the shown organs is responsible for pumping blood throughout the body?

Which of these organs helps us to think and process information?

The four internal organs visible in the diagram are the brain, heart, lungs, and stomach.

The heart is the organ shown that is responsible for pumping blood throughout the body.

The brain is the organ that helps us to think and process information, and it also controls various bodily functions.

Question 3

⁠

What physiological process is being illustrated in this two-panel diagram?

Describe what happens to the diaphragm during the ‘Inhalation’ phase.

What is the main gas that enters our body during inhalation, and what gas is primarily released during exhalation?

This two-panel diagram illustrates the breathing process, specifically showing the mechanics of inhalation and exhalation.

During the ‘Inhalation’ phase, the diaphragm contracts and moves downwards, which increases the space within the chest cavity, allowing air to rush into the lungs.

The main gas that enters our body during inhalation is oxygen, and the gas primarily released during exhalation is carbon dioxide.

Question 4

⁠

Based on the image, identify three distinct human activities or sources that contribute to air pollution.

How might living in an environment like the one depicted in the picture affect people’s health?

Besides the visible effects, what broader impact can some types of air pollution have on the Earth’s atmosphere?

Three distinct human activities or sources contributing to air pollution shown in the image are smoke from factory chimneys, exhaust fumes from cars, and smoke from burning garbage.

Living in such a polluted environment could severely affect people’s health by causing breathing difficulties, triggering asthmatic attacks, and increasing the risk of serious illnesses like lung cancer, as well as various respiratory and heart diseases.

Besides the visible effects, some types of air pollution can have a broader impact by damaging the ozone layer present in the atmosphere, which is crucial for protecting life on Earth from harmful solar radiation.
