What else can I help you with?
Which structure in the human body is similar in function to leaves?
the alveoli
Where are alveoli located in human body?
Alveoli are very tiny air sacs found in the lungs where CO2 and O2 are changed.
Which organ contains the most alveoli in the human body?
The lungs contain the most alveoli in the human body. Alveoli are tiny air sacs in the lungs where gas exchange occurs, allowing oxygen to enter the bloodstream and carbon dioxide to be removed. The large surface area of alveoli is essential for efficient gas exchange during respiration.
What do the alveoli in the body do?
alveoli take co2 from
What is the driving force behind gas exchange in the human body?
The driving force behind gas exchange in the human body is the concentration gradient of gases such as oxygen and carbon dioxide between the alveoli in the lungs and the blood in the pulmonary capillaries. Oxygen moves from the alveoli into the blood, while carbon dioxide moves from the blood into the alveoli, driven by differences in their partial pressures.
Which malfunction of the human body is characterized by an enlargement and degeneration of the alveoli resulting in the decrease lung capacity?
emphysema (C)
Which malfunction of the human body is characterized by an enlargement and degeneration of the alveoli resulting in a decreased lung capacity?
emphysema (C)
What is the path of an oxygen molecule when it enters the human body?
Nostrils-Pharynx-Trachea(Wind Pipe)-Bronchi-Bronchioles-Alveoli
Where in the human body is o2 and co2 exchanged?
Oxygen (O2) is exchanged for carbon dioxide (CO2) in the lungs. In the alveoli, tiny air sacs in the lungs, oxygen from the air is transferred into the bloodstream while carbon dioxide from the blood is released into the air to be exhaled.
How many alveoli are in a body?
3oo million alveoli
What happens at the very end of the bronchioles when the air reaches the alveoli?
it is tranfered through the alveoli to the red blood cells which Carrie it throughout the human body . when it gets back they remove the CO2 and send it back through the bronchials to be exhaled
How do human cells get rid of waste?
By the lungs and alveoli.
