The respiratory system includes the trachea, bronchi, bronchioles, lungs, and diaphragm. These structures work together to transport air and allow oxygen and carbon dioxide exchange during breathing.
The structure of alveoli shows microscopic air sacs located at the ends of bronchioles. These small lung structures are responsible for oxygen and carbon dioxide exchange during respiration.
The anatomy of the bronchioleis characterized by the absence of hyaline cartilageand walls surrounded by smooth muscle, allowing regulation of airflow toward the alveoliduring breathing.
The anatomy of the bronchi and bronchiolesshows how bronchicontain hyaline cartilagethat keeps airways open, while bronchiolesregulate airflow toward the pulmonary alveoli.
The anatomy of the lungs and bronchishows how air travels through the trachea, bronchi, and bronchioles, and alveoli, allowing oxygen and carbon dioxide exchange during breathing.
The biological process of hematosisoccurs in the pulmonary alveoli, where oxygenfrom inhaled air moves into the capillariesand binds to red blood cells, while carbon dioxide is removed.
Bronchial asthma. It represents the inflammation and narrowing
of the bronchi with mucus accumulation, causing difficulty
respiratory, wheezing, and cough, characteristic of a disease
chronic condition that affects airflow.
The bronchial branchshows how the tracheadivides into the main bronchi, which branch into secondary bronchi and bronchioles, guiding air to the alveoli for gas exchange.
The bronchial tree and lungsform a network of airways where the tracheadivides into the main bronchi, secondary bronchi, and bronchioles, guiding air to the alveoli for gas exchange.
Bronchiolesare the smallest airways in the lungs. They carry air from the bronchi to the alveoli, where oxygen and carbon dioxide exchangeoccurs during breathing.
Cardiac blood circulation describes how blood flows from
the heart to the lungs and back to the body. This process
delivers oxygen and nutrients to tissues while supporting
normal cellular function.
Cardiac layers include the pericardium, myocardium,
and endocardium. These structures protect the heart,
generate contractions, and line the heart chambers to
support efficient blood circulation.
