Respiratory Anatomy
Transports air to and from the lungs.
What is the Trachea?
Active process in which the intercostal (rib) muscles and the diaphragm contract, expanding the size of the chest cavity and causing air to flow into the lungs.
What is inhalation?
Receives unoxygenated blood from the body also, receives oxygenated blood returning from the lungs.
What is the Atria?
Blood vessels that supply the muscle of the heart (myocardium)
What are the Coronary Arties?
The smallest kind of artery?
What are the arteriole?
Site of gas exchange between air and blood.
What are the lungs?
A passive process in which the intercostal (rib) muscles and the diaphram relax, causing the chest cavity to decrease in size and air to flow out of the lungs.
What is exhiliation?
Sends oxygen-poor blood to the lungs; sends oxygenated-rich blood to the body.
What is the Ventricle?
Largest artery in the body; transports blood from the L Ventricle begin systems circulation.
What is the Aorta?
Thin-walled, microscopic blood vessels where the oxygen/carbon dioxide and nutrient/waste exchange with the body's cells take place.
What are the capillaries?
Air passageways inside the lungs.
What are the Bronchial tubes?
The process of moving gases (oxygen and Carbon dioxide) between inhaled air and the pulmonary circulation of blood.
What is ventilation?
Receives unoxygenated blood returning from the body.
What is the R Atria?
Vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs.
What is the Pulmonary Artery?
The smallest kind of vein.
What is the venule?
Microscopic sacs of the lungs where gas exchange with the bloodstream takes place.
What are the alveoli?
The process of moving oxygen and carbon dioxide between circulating blood and the cells.
What is respiration?
Sends oxygen-poor blood to the lungs
What is the R Ventricle.
Large neck arteries, one on each side of the neck, that carry blood from the heart to the head.
What are the Carotid Arteries?
Any blood vessel returning blood to the heart.
What is a vein?
Structure that divides the chest cavity from the abdominal cavity.
What is the diaphragm?
The system that helps manage the pH of the body to maintain it at a normal level.
What is the buffer system?
Sends oxygen-rich blood to the body.
What is the L Ventricle?
The major artery supplying the leg.
What are the Femoral Arteries?
Vessel that carries oxygenated blood from the lungs to the left atrium of the heart.
What is the Pulmonary vein?
