The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe)
conducts inhaled air into
the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
How are the structure and function of the lungs to support the respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work
together to move oxygen throughout the body
and clean out waste gases like carbon dioxide.
How does the structure of the alveoli relate to their function in the lungs?
Explanation: The alveoli are clusters of small sacs at the end of the bronchiole tubes. These sacs fill with air with each inhalation. … Both the alveoli and the capillary walls are one cell thick and
allows for the diffusion of Oxygen O2 and Carbon Dioxide CO2 between the lung tissue and the blood
.
How does the structure of the respiratory system help it function?
The respiratory system is the network of organs and tissues that
help you breathe
. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
What structures in the lungs have a characteristic shape important to their function?
Alveoli
are lined by a fluid called surfactant. This fluid maintains the shape of the air sac
What is the main function of alveoli?
The alveoli are where the lungs and
the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out
. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
Where does gas exchange occur in the lungs?
ALVEOLI
are the very small air sacs where the exchange of oxygen and carbon dioxide takes place. CAPILLARIES are blood vessels in the walls of the alveoli.
What is the structure of the lungs?
The lungs are a
pair of spongy, air-filled organs
located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
What are the 10 parts of the respiratory system?
- Nose.
- Mouth.
- Throat (pharynx)
- Voice box (larynx)
- Windpipe (trachea)
- Large airways (bronchi)
- Small airways (bronchioles)
- Lungs.
What is the main function of lungs?
The respiratory system's main job is
to move fresh air into your body while removing waste gases
.
What are the 2 main functions of the lungs?
What do the lungs do? The lungs' main function is
to help oxygen from the air we breathe enter the red cells in the blood
. Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of CO
2
gas when we breathe out.
What will reduce gas exchange in the lungs?
The lungs normally have a very large surface area for gas exchange due to the alveoli.
Diseases such as emphysema
lead to the destruction of the alveolar architecture, leading to the formation of large air-filled spaces known as bullae. This reduces the surface area available and slows the rate of gas exchange.
What are the features of alveoli?
- they give the lungs a really big surface area.
- they have moist, thin walls (just one cell thick)
- they have a lot of tiny blood vessels called capillaries.
What is another name for alveoli?
A pulmonary alveolus (plural: alveoli, from Latin alveolus, “little cavity”) also known as
an air sac or air space
is one of millions of hollow cup-shaped cavities in the lungs where oxygen is exchanged for carbon dioxide.
How many alveoli are there?
At the end of each bronchiole is a special area that leads into clumps of teeny tiny air sacs called alveoli (say: al-VEE-oh-lie). There are
about 600 million alveoli
in your lungs and if you stretched them out, they would cover an entire tennis court.
