What is the difference between the hilum and root of the lung?
The hilum of the lung is the area where blood vessels, nerves, and bronchi enter and exit the lung. The root of the lung refers to all the structures that connect the lung to the heart and other parts of the body. In summary, the hilum is a specific part of the lung, while the root encompasses all the structures that support and connect the lung.
Which type of transport is responsible for oxygen entering into the blood?
the answer to apex is passive.
How many layers of cells does oxygen diffuse through before it reaches a red blood cell?
Oxygen diffuses through two layers of cells: the alveolar epithelial cells lining the lung air sacs and the capillary endothelial cells before it reaches a red blood cell in the pulmonary capillaries.
What is the difference between the root and hilum of the lung?
The root of the lung is where blood vessels, nerves, and bronchi enter and exit the lung, while the hilum is the depression on the lung's surface where these structures are located.
What is the relationship between the root of the lung and the hilum?
The root of the lung is connected to the hilum, which is a region where blood vessels, nerves, and bronchi enter and exit the lung. The root of the lung serves as a pathway for these structures to enter and leave the lung.
What gases are exchanged in the repitory ystem?
Oxygen diffuses from the alveoli of the lungs into the blood. Carbon dioxide diffuses from the blood into the alveoli of the lung where is will be exhaled.
What is taken from blood when it is pumped to the lung?
When blood is pumped to the lung, carbon dioxide diffuses from the blood into the alveolus. The pumonary artery carries the blood from the heart to the lungs.
What does oxygen diffuse into?
Oxygen diffuses from any place there is a lot of it to any place where there is less. In the body, it diffuses from the air in the alveoli of the lungs, through the lung and capillary walls and into the blood, where it is taken up by the haemoglobin of the red blood cells. When the bood reaches the body tissues it diffuses out of the blood and into the cells.
Oxygenation of fetal blood occurs in the?
Oxygenation of fetal blood occurs in the placenta, where the mother's bloodstream and the fetus's bloodstream come into close proximity but do not mix. Oxygen from the mother's blood diffuses into the fetal blood, while carbon dioxide diffuses from the fetal blood into the mother's blood for elimination.
How does oxygen gets from the air to your blood?
Oxygen is inhaled through the lungs where it diffuses across the lung membrane into tiny blood vessels called capillaries. From there, oxygen binds to hemoglobin in red blood cells and is transported throughout the body to be used by cells for energy production.
The diffusion of oxygen and carbon dioxide into and out of the blood occurs in the?
If I'm not wrong, the O2 is carried from your lungs by red blood cells, then is passed to the muscles which need it through the walls of the blood vessels, while they take CO2 from the muscles to bring it back to the lungs to expel. So... it occurs through the bloodstream and the walls of the blood vessels (capillary vessels etc.)
From the right side of the heart blood goes to this?
The blood that leaves the right side of the heart is passed into the pulmonary arteries. This blood is oxygenated in the lungs and passes through the pulmonary veins into the left side of the heart.
Where carbon dioxide comes from?
it comes from carbon oxidizing through fire. It also comes from a lot of other places. Carbon dioxide is a waste product of cellular respiration. It diffuses into the blood from the cells and travels to the lung where it is exhaled into the air.
What is the difference between the hilum and root of the lung?

In summary, the hilum is a specific part of the lung, while the root encompasses all the structures that support and connect the lung.
What does perfusion of the lung involve?
absorpition of oxygen from the blood into the lung
What body system obtains oxygen for the bloodstream?
The respiratory system is responsible for obtaining oxygen from the air and delivering it to the bloodstream. This process occurs in the lungs, where oxygen is inhaled and then diffuses into the blood vessels surrounding the air sacs called alveoli.
What blood travels from the lung to the heart?
red blood
