This is another term for cellular metabolism.
This is described as the delivery of oxygen, glucose, and other substances to the cells and the elimination of waste products from the cells.
What is perfusion?
This is a mechanical process that relies on changes in pressure inside the thorax to move air in and out of the lungs.
What is ventilation?
This is defined as amount of blood ejected by the left ventricle in one minute.
What is cardiac output?
This is the resistance that is offered to blood flow through a vesesel.
What is systemic vascular resistance?
This is the breakdown of molecules such as glucose through a series of reactions that produce energy within the cells in the presence of oxygen.
What is aerobic metabolism?
This is the percentage of oxygen in ambient air.
What is 21%?
This is a measure of the ability of the chest wall and lungs to stretch, distend, and expand.
What is compliance?
The heart has this property, meaning it can generate its own impulse.
What is automaticity?
This is the term used for an increase in vessel diameter.
What is vasodilation?
This is an ion that is found mostly outside of a cell.
What is sodium?
This is an airway that is open and not obstructed by blood, secretions, vomitus, swollen tissues, bone, teeth, or any other substance.
What is a patent airway?
This is the amount of air moved in and out of the lungs in one minute.
What is minute volume?
This is defined as the volume of blood that is ejected by the left ventricle with each contraction.
What is stroke volume?
This type of stimulation causes vasoconstriction.
What is sympathetic stimulation?
This refers to the breakdown of molecules in the cells without the presence of oxygen.
What is anaerobic metabolism?
This is a flap of tissue that covers the opening of the larynx during swallowing.
What is the epiglottis?
This is an area in the respiratory tract where no gas exchange occurs.
What is dead air space?
This is the resistance in the aorta that must be overcome by contraction of the left ventricle to eject blood.
What is afterload?
This is the difference between the systolic and diastolic blood pressure readings.
What is the pulse pressure?
The process of glucose crossing a cell membrane and being broken down into pyruvic acid molecules is called this.
What is glycolysis?
A condition in which airflow is reduced by an infection that causes inflammation of the mucous lining of the bronchi.
What is bronchitis?
Specialized receptors that monitor the pH, carbon dioxide, and oxygen levels in arterial blood.
What are chemoreceptors?
What law of the heart states that the stretch of the muscle fiber at the end of diastole determines the force available to eject blood from the ventricle.
What is the Frank-Starling law of the heart?
An increase in blood pressure causes greater stretch in the walls of the arteries which stimulates these receptors.
What are baroreceptors?
