oxygen, carbon, hydrogen, nitrogen, phosphorous, and calcium.
Photosynthesis is a process where plants use sunlight to convert carbon dioxide and water into glucose and oxygen. Respiration is the process where organisms break down glucose to release energy, using oxygen and producing carbon dioxide and water as byproducts. Essentially, photosynthesis produces glucose and oxygen, while respiration consumes glucose and oxygen to release energy.
Gaseous exchange takes place in the alveoli (in the lungs) -Carbon dioxide is a waste product of aerobic respiration, therefore it is transported via the heart to the lungs to be breathed out in exhalation becasue it isn't needed. Hope this helps
oxygen
When people are running they expending energy. More energy is needed to be made from stored energy. The way for this to happen is hydrogen and oxygen atoms to connect and form water. More oxygen needs to be produced for this process to happen that is why heavy breathing occurs.
its denser than oxygen and our bodys werent ment to use it
The circulatory system and respiratory system work together to provide the body's cells with oxygen and to carry away the carbon dioxide that cells generate as respiratory waste. The respiratory system gets air into lungs and in the small air sacs were oxygen is transported into the blood, and the circulatory system carries the oxygen in the red blood cells and delivers it to cells in need of oxygen. The oxygen is stored in the hemoglobin in the blood, and the blood is pumped around the bodily organs by the heart, releasing oxygen at the organs.
Capillaries
oxygen and nutrients
without nitrogen our bodys would over oxygenate (get to much oxygen). nitrogen is important for plants, after all they breath in nitrogen and breath out oxygen.
Deoxygenated blood, also referred to as oxygen-poor blood or venous blood. This blood is returning to the heart after delivering oxygen to the body's cells.
