Lungs are a vital part of the respiratory system they inflate when you inhale oxygen and deflate when you exhale carbon-dioxide When you smoke it affects your lungs. The drugs infect it and turn your lungs black which makes it hard to do sports, jog pretty much do any hard physical labor
You can get lung cancer from smoking Stages of Lung Cancer Stage 0 Cancer that is found only in the layer of cells lining the air passages. Possible treatment: Not applicable
SStage I CCancer cells are limited to the lung. Tissue around the lung remains normal. Stage I is divided into IA and IB, depending on the tumor size or if a main bronchus is involved. Possible treatment: Surgery, radiation therapy, and/or chemotherapy. *
Stage II Cancer has spread to lymph nodes, chest wall, diaphragm, lining of the lungs, or the outer lining that surrounds the heart. Stage II is divided into IIA and IIB, depending on the tumor size or if a main bronchus is involved. Possible treatment: Surgery, radiation therapy, and/or chemotherapy
Stage III ** Cancer has spread to the lymph nodes in the area of the chest between the heart and lungs. Blood vessels in this area may also be affected. Cancer may also have spread to the lower neck. Stage III is frequently referred to as “locally advanced
Stage IIIA ** The cancer has spread to lymph nodes in the center of the chest, on the same side as where the cancer started. Possible treatment: Surgery, radiation therapy, and/or chemotherapy
Stage IIIB ** The cancer has spread to lymph nodes on the opposite side of the chest and cannot be removed with surgery. Possible treatment: Radiation therapy, combinations of chemotherapy, and/or targeted therapies
Stage IV ** Cancer has spread to the other lung or to other areas in the body and cannot be removed with surgery. Possible treatment: Radiation therapy, combinations of chemotherapy, and/or targeted therapies
The bronchi connects the lungs together The bronchi sends oxygen to the lungs so you can breath The bronchi is coated with mucus it has smaller tubes inside the bronchi Asthma swells up the bronchi
From the larynx, a tube called the trachea carries air to the lungs. *The trachea leads to two branches called bronchi that go into the lungs. *In the lungs the bronchi branch into smaller and smaller tubes called bronchioles. *Asthma is a disease in which these tubes may become swollen.*This keeps air from moving easily through the lungs.*The bronchioles end in clusters of tiny, thin-walled sacs in the lungs.*The air sacs are where oxygen enters the blood and carbon dioxide leaves the blood.
from the nose, air passes through the nasal cavities. the nasal cavities warm and moisten the air. then, the air moves to the back of the throat and into the larynx. the sound of your voice is the result of your breath making the vocal cords vibrate.
when muscles stretch the vocal cords tighter, your voice gets a higher pitch. the larynx contains the vocal cords, where the voice is produced.
All of your cells need oxygen. You have a respiratory system and a circulatory system that work together to get oxygen to your cells. Oxygen enters your body when you inhale. Your respiratory system gets the oxygen as far as the tiny air sacs inside your chest. The blood picks up the oxygen there and carries it to your heart, where it is pumped to all of your cells- all the way down to your toes! Two things happen at the same time in the air sacs. Oxygen leaves the lungs and enters the blood. Carbon dioxide moves the other way.
When you inhale, a dome shaped muscle called the diaphragm moves down, making more space in your chest for air. Your rib muscles may also pull your rib cage up and out, making still more space. As blood flows through the capillaries on air sacs, oxygen from the air enters into the blood Draw arrows on the red and blue blood vessels below to show the direction of blood flow.
