Summary of Human Body: Respiratory System

Tujuan

1. Identify the key organs of the respiratory system and their respective roles.

2. Comprehend the basic functioning of the human respiratory system.

3. Link knowledge of the respiratory system to potential career opportunities in fields like healthcare and biotechnology.

Kontekstualisasi

The human respiratory system is vital for our survival, facilitating the gas exchange that helps us inhale oxygen and expel carbon dioxide. If this system doesn't work effectively, our cells can't perform their essential functions. From the quiet breath we take in our sleep to the fast panting after a good run, the respiratory system tirelessly works to keep our bodies in balance. For instance, healthcare professionals rely on their understanding of the respiratory system to treat conditions such as asthma and pneumonia. Additionally, biomedical engineers create technologies like artificial ventilators to aid patients struggling with breathing issues.

Untuk Diingat!

Nose

The nose serves as the primary entry point for air into the respiratory system. It warms, moistens, and filters the air we breathe in, removing dust and germs. The nose also houses the receptor cells responsible for our sense of smell.

• Warms inhaled air to prevent thermal shock to the lungs.

• Moistens the air to safeguard respiratory tissues.

• Filters out particles and microorganisms to fend off infections.

• Contains olfactory cells that detect various smells.

Trachea

The trachea is a tube connecting the larynx to the bronchi. It features rings of cartilage that keep it open for airflow. The trachea also has cilia and mucus that help capture and remove any foreign particles.

• Connects the larynx to the bronchi, facilitating airflow.

• The cartilage rings keep the trachea open.

• Cilia and mucus work to eliminate foreign particles and germs.

• Key for protecting the lower respiratory system.

Lungs

The lungs are the main organs involved in the respiratory process, where gas exchange happens. They are divided into lobes and contain millions of tiny air sacs called alveoli, where oxygen is absorbed from the air and carbon dioxide is released from the blood.

• The primary site for gas exchange between air and blood.

• Divided into lobes for effective organization and functioning.

• Composed of millions of alveoli, increasing the surface area for gas exchange.

• Critical for oxygenating the body and removing carbon dioxide.

Aplikasi Praktis

• Healthcare providers use their knowledge of the respiratory system to diagnose and treat issues like asthma and pneumonia.

• Biomedical engineers create devices such as artificial ventilators to support patients with respiratory issues.

• Physiotherapists apply respiratory rehabilitation techniques to enhance lung function and improve quality of life for patients with chronic respiratory problems.

DIY Lung Challenge

Create a working model of a lung using simple household materials to showcase how respiration works.

Instruksi

• Gather the necessary materials: a plastic bottle, two balloons, a straw, tape, and scissors.

• Cut the bottom off the plastic bottle.

• Fit one balloon over the mouth of the bottle and secure it with tape.

• Insert the straw into the bottle, through the mouth and balloon.

• Seal the opening around the straw with tape.

• Place the second balloon in the opening of the cut bottle and secure it with tape.

• Pulling and pushing the balloon at the bottom of the bottle simulates inhalation and exhalation.

• Explain what happens to the inner balloon (lung) when the outer balloon (diaphragm) is pulled or pushed.
