During photosynthesis, carbon dioxide and oxygen are exchanged. The plant uses the carbon dioxide for the photosynthesis and expels oxygen.
1.For birds to be able to take flight or fly high enough and still obtain enough oxygen, the birds have air sacs. 2.(Air sacs are membranaceous receptacles which communicate with the cavities of the respiratory organs passages, and can through be filled with air.) I really hoped this helped, now remember the answer to the question is number 1. The definition of air sacs is number 2.
There are 5 parts involved in respiration:1. Pulmonary ventilation or breathing.2. External respiration where air flows into the lungs and gases exchange (O2 load/ CO2 unload) and air goes out.3. Transport of respiratory gases by way of blood transport from the lungs to body cells and back to lungs.4. Internal respiration is where exchange of gases occurs at the body capillaries (O2 unload/CO2 load).5. Cellular respiration which is the use of oxygen by cells to produce energy (production of CO2).
there are many gases polluting the Earth but the main 2 are oxygen and carbon dioxide.
Nitrogen (79%) and oxygen (20%).
There are not a lot of noble gases that are in the atmosphere. It is estimated that about 2 percent of the atmosphere contains them.
Air enters through the oropharynx or nasopharynx to the trachea to the bronchii to the alveoli of the lungs to the blood vessels of the pulmonary vein to the heart to the arteries to the capillaries to the veins to the heart to the pulmonary artery to the alveoli of the lungs to the bronchii through the trachea out of the naso or oropharynx and back into the atmosphere to the broadleaf plants to the atmosphere to the . . .
The air we breathe contains 78% Nitrogen and 20% Oxygen. The remainder is Helium and other gases
most of the air is made up of nitrogen and oxygen. But, 2% of the air is made up of other different kinds of gasses
78% nitrogen 20% oxygen and 2% other inert gases.
Apparently, there are two babies.
