68WM6 Ph.1 Mod 4

68WM6 Ph.1 Mod 4 Terms. Acid/Base, Respiratory and Digestive System.

QuestionAnswer
Alveolus Microscopic air sac within the lung, where gas exchange takes place.
Apnea Cessation of breathing after expiration.
Bronchial Tree The bronchi and their branches that carry air from the trachea to the alveoli of the lungs.
Bronchus A primary branch of the trachea that leads to the lung.
Bronchioles A small branch of a bronchus within the lung.
Cellular Respiration The utilization of O2 by the cells to produce energy (ATP), CO2 and H20.
Cricoid Cartilage Ring-shaped mass of cartilage at the base of the larynx.
Dyspnea Difficult or labored breathing.
Eupnea Normal (Quiet) breathing.
External Respiration Exchange of gases between alveoli and blood.
Hyperventilation Prolonged rapid and deep breathing.
Hypoxemia Deficiency of O2 in arterial blood.
Hypoxia Deficiency of O2 reaching the tissues and cells. Two types: Ischemic and Anemic
Anemic Hypoxia Deficiency of O2 caused by diminished RBCs and Hemoglobin
Ischemic Hypoxia Deficiency of O2 caused by diminished blood flow.
Internal Respiration Exchange of gases between the blood and tissues/body cells.
Pulmonary Ventilation Process of mechanically moving air into and out of the lungs.
Respiration The entire process of exchanging gases between the atmosphere and body cells.
Respiratory Cycle One inspiration followed by one expiration.
Surface Tension The force that adheres moist membranes due to the attraction of water molecules.
Tachypnea Increased breathing(frequency) but not necessarily an increase in tidal volume.
Upper Respiratory Tract Includes the nose, nasal cavity, paranasal sinuses and pharynx.
Lower Respiratory Tact Includes the larynx, trachea, bronchial tree and lungs.
Assimilation The utilization of nutrients by living tissue.
Absorption The movement of nutrients into the circulatory system.
Bolus A mass of food and saliva that is ready to be swallowed.
Chyme A semi-fluid mixture of food and gastric juice.
Digestion The mechanical and chemical breakdown of foods and the absorption of the resulting nutrients by cells.
Defecation The elimination of indigestible substances from the colon.
Ingestion The taking in of food into the mouth.
Mechanical Digestion The process of breaking food down into smaller pieces without altering the chemical composition.
Chemical Digestion The process of breaking down food into simpler chemicals.
Alimentary Canal Muscular tube that passes through the body's ventral canal. (Mouth to Anus)
Metabolic Alkalosis Blood pH 7.45+ followed by an Increase in HCO3- and/or Increase in PaCO3
Metabolic Acidosis Blood ph 7.35- followed by a Decrease in HCO3- and/or Decrease in PaCO3
Respiratory Alkalosis Blood pH 7.45+ followed by a Decrease in PaCO3 and/or Decrease in HCO3-
Respiratory Acidosis Blood pH 7.35- followed by an Increase in PaCO3 and/or Increase in HCO3-
Anchar Cells Cells that produce the pancreatic juice.
3 Salivary Glands Parotid, Submandibular and Sublingual.
3 Divisions of the Small Intestine Duodenum, Jejunum and the Illeum.
The shortest and most fixed portion of the small intestine. Duodenum

The remainder of the free, mobile portion of the small intestine. Ileum
Vital Capacity The maximum amount of air a person can exhale after taking the deepest breath possible. (4600mL)
Inspiratory Capacity The maximum volume of air a person can inhale following a resting expiration. (3500mL)
Tidal Volume The volume of air that is inspired or expired during a normal respiratory cycle. (500mL)
Inspiratory Reserve Volume Constitutes the maximum air that can be inspired beyond normal tidal inspiration during forced inspiration. (3000mL)
Expiratory Reserve Volume Constitutes the maximum amount of air that can be expired beyond normal tidal expiration during forced expiration. (1100mL)
Residual Volume Constitues the amount of air that remains in the lungs after maximum forced expiration. (1200mL)
Functional Residual Capacity The volume of air that remains in the lungs following a resting expiration. (2300mL)
Acid A solution that has a pH balance less than 7.0
Normal blood pH range. 7.35 to 7.45
Base A solution that has a pH balance greater than 7.0. A.K.A. Alkali
List of Electrolytes Sodium (Na+), Potassium (K+), Calcium (Ca2+), Magnesium (Mg2+), Chloride (Cl-), Phosphate (PO4^3-) and Bicarbonate (HCO3-)
