Oxygen from the air is diffused into the bloodstream in the lungs through tiny air sacs called alveoli, where it binds to hemoglobin in red blood cells. This process is facilitated by the high surface area of the alveoli and the thin walls that allow for rapid gas exchange. Additionally, the respiratory system has a rich network of capillaries surrounding the alveoli to quickly transport oxygen to the rest of the body.
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.
express.howstuffworks.com/web-quest- ... The blood carries the much-needed oxygen to the muscles. While this is going ... It's also removing fluid from your body, so it's very important to replace those lost fluids.
When you bleed, your blood appears dark because it lacks oxygen. Oxygen-rich blood is bright red, but when it comes into contact with air and loses its oxygen, it turns dark red.
They all enter the lung ... but the only one that quickly enters the blood is oxygen. Because oxygen is the one gas that has a higher partial pressure in "lung air" than its partial pressure in the "lung blood". Note that the blood's CO2 pressure is higher than the air in the lungs, so CO2 comes out of the blood into the lung's air.
If the jar holding the oxygen breaks, the oxygen will escape into the surrounding environment. Oxygen is a gas, so it will disperse quickly and mix with the air around it.
because your blood carries oxygen to you muscles. without much oxygen blood won't be able to take lots to your muscles, and with little oxygen your muscles won't work as well and therefore you won't run as quickly :)
To be "oxgenated" means the blood holds oxygen, so "oxygenated blood" carries O2 laden blood.
To supply blood with oxygen so the blood can deliver the oxygen throughout the body.
because when you exercise your muscles require more oxygen so your heart will beat faster to get the oxygen to the mucsles. since your blood goes through the lungs and your heart is beating faster you must breathe faster to get a sufficient amount of oxygen.
Because you need to do so to survive. Without blood circulating through the lungs, it would not be able to distribute oxygen to areas like muscle groups or the brain, and the body would quickly die.
Every part of the human body needs oxygen, but the heart and the brain are the most critical body parts that will die soonest if they are deprived of oxygen. The brain dies in just 3 minutes without oxygen. Oxygen is carried by the blood, so if there is not enough blood, there will not be enough oxygen.
All the cells require oxygen, and so the way of them getting it is via the blood.
So the blood can pick up oxygen and release carbon dioxide.
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.
Well, the lungs are where the oxygen is added to the blood. So, the short answer is 'no.' There may be some oxygen left, but the blood would probably be a deep blueish color. When the oxygen is added the blood turns red.
the Red Blood cells so they can carry oxygen.
it contains oxygen so you can breathe and it contains blood cells
