Inhalation/Inspiration
they enter the lungs in order to obtain oxygen and get rid of carbon dioxide. this process occurs in the alveolus of the lungs by diffusion.
It's called drowning.
It's called the "bronchial tree".
They are called alveoli
Pulmonary oedema
Passages through which air enters the lungs is called the bronchi which branch off of the trachea.
oxigen is the gas that enters the blood through the lungs
oxigen is the gas that enters the blood through the lungs
Oxygen enters via the lungs.
Homework question? Well, I am sure you know we breath in oxygen and it enters the blood in the lungs. That oxygen is used in your cells to turn food into energy in a process called cellular respiration. When this process uses oxygen we call it aerobic respiration (meaning "with air") The part of the process that uses the oxygen is the Kreb's cycle. The process produces a waste gas that is eliminated in the lungs at the same time the oxygen enters. What you need to ask yourself is...what is the opposite of oxygen? A hint, plants do it the other way around, they breathe in ______ and the waste they produce is oxygen. Hope this helps! D
We breath because the oxygen/CO2 levels in our lungs are less than that of our surroundings. When you breathe in, your lungs expand and allow more oxygen to flow in. When you exhale, the CO2 levels in your lungs is greater than the your surroundings, so the CO2 leaves and the process repeats itself. This is called negative pressure breathing.
