How do you release carbon dioxide from your body?
The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out. When you breathe in, the diaphragm moves downward toward the abdomen, and the rib muscles pull the ribs upward and outward.
What does the blood pick up from the digestive system?
Digestive system. As food is digested, blood flows through the intestinal capillaries and picks up nutrients, such as glucose (sugar), vitamins, and minerals. These nutrients are delivered to the body tissues by the blood. Kidneys and urinary system.
Where does blood pick up oxygen?
Red blood cells pick up oxygen in the lungs. Blood travels away from the heart and lungs through the arteries (ar-tuh-reez). Red blood cells drop off oxygen to the cells through tiny tubes called capillaries (cap-ill-air-ies). Blood then returns to the heart through the veins (vayns) and the cycle begins again.
Where do the red blood cells pick up oxygen and drop off carbon dioxide?
IN THE LUNGS, THE RED BLOOD CELLS IN BLOOD DROP OFF CARBON DIOXIDE TO THE AIR IN THE ALVEOLI (BY A PROCESS CALLED DIFFUSION) AND PICK UP OXYGEN FROM THE AIR IN THE ALVEOLI. IN THE CAPILLARIES, THE RED BLOOD CELLS DROP OFF OXYGEN TO THE BODY’S CELLS AND PICK UP CARBON DIOXIDE FROM THE CELLS.
