Ch 2 - Excercise Physiology Flashcards
Atria
Receiving chamber
Ventricle
Pumping chamber
Arteries
These vessels bring oxygenated blood away from the heart and to the rest of the body
Veins
These vessels bring deoxygenated blood to the heart to be pumped to the lungs to get oxygen
Capillaries
Location of nutrient, gas and waste exchange
Residual Volume (RV)
The volume of air still remaining in the lungs after the most forcible expiration possible and amounting usually to 60-100 cubic inches
Pulmonary Ventilation
A measure of the rate of ventilation, referring to the total exchange of air between the lungs and the ambient air
Total Lung Capacity (TLC)
The amount of gas contained in the lung at the end of a maximal inhalation
Inspiratory Reserve Volume (IRV)
The maximal amount of additional air that can be drawn into the lungs by determined effort after normal inspiration
Tidal Volume (TV)
The lung volume representing the normal volume of air displaced between normal inspiration and expiration when extra effort is not applied
Expiratory Reserve Volume (ERV)
The additional amount of air that can be expelled from the lungs by determined effort after normal expiration
Nose
An area which admits and expels air for respiration in conjunction with the mouth
Bronchi
This is a passage or airway in the respiratory tract that conducts air into the lungs
Lungs
This is the essential respiration organ in many air-breathing animals
Alveoli
This is an anatomical structure that has the form of a hollow cavity. It is found in the lungs, at the terminal end of bronchioles. Here is the sites of gas exchange with blood and oxygen.
Bronchioles
In the lungs, there are a left and right branch is the bronchi. Following that is this structure, which divide further into smaller and smaller terminals.
Trachea
Also called windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in all air-breathing animals with lungs
Mouth
This is the opening through which many animals take in food and issue vocal sounds
Pharynx
The function of this structure is to filter, warm, and moisten air and conduct it into the lungs. It makes up the part of the throat situated immediately posterior to the mouth and superior to the oesophagus and larynx.
Larynx
This is commonly called the voice box, and is an organ in the neck of amphibians, reptiles and mammals involved in breathing, sound production and protecting the trachea against food aspiration
Heart
Center of the whole cardiovascular system muscular organ
Name the four chambers of the heart
Right atrium, right ventricle, left atrium, and left ventricle
Name of the four valves in the heart
Bicuspid, tricuspid, aortic and pulmonary valve
Name of the four major blood vessels
Vena cava, pulmonary vein, aorta, and pulmonary artery
