If you held your breath, the concentration of oxygen in your lungs would decrease. The concentration of carbon dioxide would increase in your lungs.
Oxygen moves from high concentration in the lungs to low concentration in the blood for delivery to tissues, while carbon dioxide moves from high concentration in the tissues to low concentration in the lungs for removal from the body.
Red blood cells transport oxygen from the lungs to tissues through the protein hemoglobin, which binds to oxygen in the lungs and releases it in tissues. This process is facilitated by the high concentration of oxygen in the lungs and lower concentration in tissues, creating a gradient for oxygen to be transported. The shape and characteristics of hemoglobin allow for efficient binding and release of oxygen as needed by the body.
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.
The pulmonary vein carries blood with the highest oxygen concentration, as it transports oxygen-rich blood from the lungs to the heart. This freshly oxygenated blood is then pumped out to the rest of the body by the heart.
Oxygen diffuses rapidly into the blood due to the concentration gradient between the alveoli in the lungs and the blood in the capillaries surrounding them. The alveoli have a high concentration of oxygen, while the blood has a lower concentration, which drives the diffusion of oxygen across the thin walls of the alveoli and capillaries. Additionally, the large surface area and short diffusion distance in the lungs help facilitate the rapid diffusion of oxygen into the blood.
DECREASE :O
When you inhale, you breath in oxygen and your lungs get bigger.
If you hold your breath, the concentration of oxygen in your lungs will decrease as your body uses up the available oxygen. At the same time, the concentration of carbon dioxide will increase as it accumulates from your body's metabolic processes. This imbalance triggers the urge to breathe and is essential for maintaining proper gas exchange in the body.
Well, first you lungs breath in and breath out air. (Inhale is to breath in Oxygen)(Exhale is to breath out carbon dioxide or wastes) Your lungs have aveioli. These are inside of the lungs. They help collect nutrients from your food. Then all the wastes are exhaled from the lungs. But, where does this all start out from? When you breath in. And out. It happens in a matter of seconds. Your body works so well. Just think about it. Your body can move that fast. Everytime you breath in and breath out. Well, the air or oxygen moves to the lungs, then aveioli collects the nutrients, this is then moved into your blood. Fascinating, huh? Your blood then uses that nutrients to help the rest of your body!
You breath.
with lungs you breath air and with gills you breath in water
All of the air in the lungs gets exchanged with oxygen upon each breath. We exhale carbon dioxide and inhale oxygen.
Lungs are organs of purifying oxygen in the body, they breath in i.e. inspiration, the fresh air carrying oxygen, and breath out i.e expiration the CO2
lungs they do have lungs they come up to breath
the oxygen in your blood comes from the air you breath in . It goes in through your mouth into the lungs and the oxygen gets taken out from the lungs into the cappilaries.
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
