The oxygen molecule will enter the capillary. It will get attached to haemoglobin molecule of the red blood cell. The blood (and the red blood cell) will be carried to left atrium via the pulmonary vein. From there the blood will go to to left ventricle. From there it will be carried to ascending aorta, arch of aorta and descending aorta. Then it will go to abdominal aorta. Then it will go to common iliac artery. Then it will go to common iliac artery. Then it will go to external iliac artery. Then it will go to femoral artery. Then it will go to posterior tibial artery. Then from the proximal end of the capillary there, it will enter the interstitial compartment. From there it will go to the muscle cell.
A group of muscle cells grouped together is called a muscle fiber. Muscle fibers come together to form muscle tissues, which in turn form muscles.
The nose serves as the primary entrance for air into the respiratory system. It warms, filters, and humidifies air as it passes through to the lungs. Additionally, the nose contains specialized cells that detect smells and help with the sense of taste.
Moisture in your nose helps to humidify and filter the air you breathe, making it easier for your lungs to extract oxygen and stay healthy. It also plays a role in protecting the delicate tissues inside your nose from irritation and dryness.
Respiration typically begins in the nose or mouth, where air is inhaled and then travels down the respiratory tract to the lungs. In the lungs, oxygen is taken up by red blood cells and carbon dioxide is released for exhalation.
The nose is part of the respiratory system, responsible for breathing oxygen into the body. It also plays a role in the immune system by filtering out foreign particles and germs to prevent them from entering the body.
It allows oxygen to travel to your lungs from your mouth and nose when you inhale. When you exhale, it pushes carbon dioxide out through your mouth and nose. It's basically your windpipe.
Nose>>>pharynx>>>larynx >>>trachea >>>bronchus >>>bronchiole >>>alveolus
A molecule of oxygen enters the body through the nose or mouth, travels down the trachea, passes through the bronchi and bronchioles, and finally reaches the alveoli in the lungs where oxygen diffuses into the bloodstream through the thin walls of the alveoli.
It (oxygen) enters the lungs, is absorbed by the alveoli in the walls of the lungs, transferred in red blood cells to the heart, where it is pumped into the aorta, then to the arteries and veins and then the capilaries that feed the hair follicles which reside above the temporalis muscle.
An oxygen mask is a device that is worn over the nose and mouth to supply oxygen from a storage tank or oxygen concentrator to a person who is having difficulty breathing or who needs additional oxygen to maintain normal oxygen levels in their blood. It is commonly used in medical settings, such as hospitals or during air travel.
Your lungs circulate oxygen every time you inhale and exhale. They travel through your body when you inhale to the lungs and the lungs store the oxygen, and as you exhale, carbon dioxide from the air is released.
The mouth or nose inhales oxygen. Then the oxygen goes into the lungs.
They all enter the lung ... but the only one that quickly enters the blood is oxygen. Because oxygen is the one gas that has a higher partial pressure in "lung air" than its partial pressure in the "lung blood". Note that the blood's CO2 pressure is higher than the air in the lungs, so CO2 comes out of the blood into the lung's air.
Oxygen itself will not cause sores in your nose. If you are receiving the oxygen via nasal prongs or some sort of pipe that enters the nose, the pipe or prongs can cause irritation of the skin, resulting in sores.
The respiratory tract begins with the mouth or the nose, and then the pharynx, larynx, trachea, bronchus, bronchioles, and then the oxygen exchange occurs in the alveoli.
The air enters through the mouth or the nose and is pulled down through the windpipe into the lungs. From the lungs, the oxygen molecules are dissolved in the alveoli and enter the red blood cells in the capillaries of the lung. From the capillaries, they travel to the heart and push oxygen through the body.
When we inhale through the nose, we breathe in oxygen and some carbon dioxide. When we exhale, there is more carbon dioxide than oxygen. This is because the oxygen is absorbed and converted by the lungs into carbon dioxide.
