What else can I help you with?
What moves oxygen into cells throughout the body?
blood
What happens to the oxygen level in blood as it moves through the lungs?
As blood moves through the lungs, oxygen is exchanged for carbon dioxide. Oxygen diffuses from the air in the lungs into the blood, increasing the oxygen level in the blood. Conversely, carbon dioxide diffuses from the blood into the air in the lungs, decreasing the carbon dioxide level in the blood.
Describe what happens in the alveoli sacs?
When we inhale in and out oxygen moves from the alveoli to blood carbon dioxide moves from blood to alveoli.
What is the correct order of the following - 'a' oxygen rich blood arrives at capillaries - 'b' oxygen enters body cells - 'c' heart pumps oxygen rich blood - 'd' oxygen moves through capillary walls?
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
What happens adter old blood moves into the heart?
Oxygen.
What happens to the oxygen levels in the blood as it moves through the lungs?
the oxygen releases carbon dioxide
Why oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
What the blood have when it moves to the lungs?
The questions leads towards which physiological important gases the blood contains.When the blood moves TO the lungs it has both CO2 (carbondioxide) and O2 (oxygen). However the level of oxygen is lower, and the level of CO2 is higher than with blood coming from the lungs.
What moves into the capillaries into the alveoli?
probably oxygen
Do veins collect plasma?
No they do not. "Veins" are in fact, the blood vessel that moves blood to the heart so that it can get moved to the lungs in order to gain oxygen. "Arteries" are the blood vessel that moves blood away from the heart so that way the various body parts can gain that oxygen to do there thing.
The gas that goes into the blood stream through the blood is?
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
Why is it necessary for the heart to beat faster when doing physical activity?
The body requires more oxygen during physical activity. Blood carries oxygen to the muscles and organs. The heart moves the blood. So the heart beats faster to move the oxygen-carrying blood to the muscles.
