What else can I help you with?
Why do our lungs have a huge amount of capillaries?
It is because your body requires a lot of surface area for diffusion of gasses into the blood.
What is the substance that the capillaries absorb from the lungs?
The capillaries absorb oxygen at the lungs. This occurs near the alveoli.
O2 enters the capillaries and ----- from the capillaries passes in to the lungs?
Carbon dioxide is produced as a waste product of respiration, and is taken in the bloodstream to the capillaries outside the lungs, where the CO2 diffuses into the alveoli of the lungs.
Oxygen diffuses into the capillaries of the lungs because there is a?
greater concentration of oxygen in the air sacs of the lungs than in the capillaries.
How are the lungs and the capillaries connected?
The lungs contain air sacs called alveoli which are surrounded by blood capillaries to allow gaseous exchange.
Capillaries are to body tissues as are to lungs?
oxygen
Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
What process is used to move oxygen into the capillaries of the lungs?
The process used to move oxygen into the capillaries of the lungs is called diffusion. Oxygen in the alveoli of the lungs moves across the thin walls of the alveoli and the capillaries by diffusion, from an area of high concentration to an area of low concentration, facilitated by the pressure difference between the alveoli and the blood in the capillaries.
How does marijuana get inside you?
It enters through the capillaries of the lungs.
What passes from the capillaries into the lungs?
Carbon dioxide is exhaled
What sort of blood vessels are surrounding the air sacs in your lungs?
Capillaries are the blood vessels that surround the alveoli, or air sacs, in your lungs. These capillaries are the site of gas exchange.
The transport of oxygen by hemoglobin occurs in the?
capillaries between the cells in the lungs or the capillaries between the cells in the body
