The Importance of Oxygen in Animals
The question is...
WHY DO ALL LIVING THINGS NEED OXYGEN? The answer is... All living things need oxygen because we use it to make energy. We get this energy through a process called cellular respiration. Cellular respiration is the process in which chemical energy stored in glucose is used to make ATP. This occurs in the mitochondria. ATP consists of three phosphate groups bonded together that is high in potential energy. Therefore, when one of the group breaks off from the chain, energy is released, and the two remaining phosphate groups becomes ADP. The energy produced from this separation is used to carry on essential living processes, such as digestion. Therefore, without oxygen, cellular respiration would not be able to occur, leading to a lack of energy and death. |
The question is...
HOW DO WE GET OXYGEN AND RELEASE CARBON DIOXIDE? The answer is... When we breathe in, the alveoli (tiny air sacs in our lungs) have more oxygen than the blood vessels/capillaries. Diffusion occurs, the oxygen going through the thin membrane and into the blood vessel. The oxygenated blood is pumped to the heart. The heart distributes the blood to the tissues that need it. Because of the burning of fuel that has oxygen, carbon dioxide (waste) is formed and is brought back to the lungs. The air in the alveoli have hardly any carbon dioxide, therefore, the carbon dioxide is diffused into the alveoli and into the air. |
The question is...
What are the parts of the human respiratory system?
The answer is...
Lungs- Oxygen is taken in and carbon dioxide is taken out
Trachea- Filters the air we breath
Bronchi- Two air tubes that carry air into the lungs
Bronchioles- Smaller airways that carry air into the lungs
Alveoli- Oxygen diffuses into blood
Diaphragm- Allows air in and forces air out
Nasal Cavity- Filters air
Larynx- Controls air flow

Gas Exchange in Jellyfishes
The question is...
HOW DO JELLYFISHES GET OXYGEN AND RELEASE CARBON DIOXIDE? The answer is... Unlike humans and other animals, jellyfishes do not have an actual respiratory structure. Instead, jellyfishes get oxygen and release carbon dioxide through a process called diffusion. Diffusion is the process in which there is movement from high concentration to low concentration. The diffusion in jellyfish occurs between the jellyfishes' cells and the surrounding water. Oxygen from the surrounding water is diffused in, while carbon dioxide from the jellyfish is diffused out.
