Respiratory System Addie kamis e block life Science march 28

Vocal Chords- They protect the airway from choking on foreign bodies in the throat. They also regulate the flow of air into our lungs and help with production of sounds used for speech.

Trachea- The trachea filters air in detail and is also known as the windpipe.

Lungs- This is the main organ of the respiratory system, it is where oxygen is taken to and carbon dioxide is moved out of.

Diaphragm- It is the primary muscle used in the process of respiration, or inhalation.

Larynx- The larynx allows air to be directed into organs for gas exchange. It is also known as the organ that is responsible for producing vocal sounds, therefore it is also reffered to as the voice box.

Respiratory Disesase: Lung Cancer

Lung cancer is a respiratory disease that is often associated with smoking, but the disease can affect non-smokers as well, although not smoking iS The most effectIve way to prevent this diSease. It kills about 16,000 to 24,000 Americans each year making it the most deadly type of cancer. Like all cancers, it is caused by the uncontrolled growth of abnormal cells. Treatments vary but may include surgery, chemotherapy, radiation therapy, targeted drug therapy, and immunotherapy. This image Is of a Smokers lungs vs a non smoKers Lungs.

Function of the Respiratory System

The respiratory system has five main functions.


2. External respiration exchanges gases between the lungs and the bloodstream ( oxygen is exchanged for carbon dioxide waste)

3. Internal respiration exchanges gases beween the bloodstream and body tissues (bloodstream delivers oxygen to cells and removes waste carbon dioxide)

4. Air vibrating the vocal chords (creating sound)

5. olfaction (smelling things)

The picture shows the main organs that fulfill these processes.

How the Respiratory System Works With Other Body Systems

The circulatory system and respiratory system need each other in order to thrive. The circulatory system pumps blood throughout the body, and the respiratory system performs the gas exchange that keeps the blood fresh. The heart is connected to the lungs via the pulmonary arteries and veins.

Breathing Process

When you breathe in (inhale), your diaphragm contracts and moves downward. This opens up a greater space in your chest cavity, into which your lungs expand. The intercostal muscles , which lay inbetween your ribs, also help to Make the chest cavity bigger. They Tighetn to pull your rib cage upward and outward when you inhale as seen in the diAgram.

Fun Facts

1. The right lung is slightly larger than the left as shown in the pIcture.

2. The surface area of the lungs is roughly Half of the size Of a tennis court.

3. Elephants have a unique respiratory system, because they are the only animals that contain a thin sheet of tissue called the pleura that wraps around the lungs and lines the chest cavity.

4. Pulmonary circulation, the process by which blood travels from the heart to the lungs and then back to the heart, was first described in the 13th century.

5. One of the main reasons why people can't seem to get "comfortable" in a sleeping position at night is because there is not enough equal air flow balanced between both nostrils.
