A timeline of the teeth (Explained - No Audio)

By: HWC, Views: 5599

Although most babies don't appear to have any teeth when they are born, they are in fact already well developed out of sight beneath the gum. The first molars erupt at about 12-14 months. The canines follow at about 16-18 months . By 3 years old, the second molars have usually erupted, c...

Deglutition

By: HWC, Views: 6238

Swallowing occurs in three stages: • Voluntary stage in the mouth. • Involuntary pharyngeal stage. • Involuntary esophageal stage. • During the voluntary stage the tongue pushes the food bolus into the oropharynx. • During the involuntary pharyngeal stage the bolus is moved ...

Oxygen - hemoglobin dissociation curve & Hemoglobin's affinity with oxygen - acidity

By: HWC, Views: 7287

• The partial pressure of oxygen is a primary factor influencing the degree of saturation of hemoglobin. • The Po2 determines the number of oxygen molecules that can bind or dissociate from hemoglobin. • Blood in vessels coming from the lungs is very high in Po2 so saturation is high. ...

Bulk flow - factors that influence bulk flow

By: HWC, Views: 6316

• Bulk flow helps regulate the relative volumes of blood and interstitial fluid. • Flow from blood to interstitium is called filtration. • Flow from interstitium to blood is called reabsorption. • Four factors determine the net direction of capillary exchange. • These factors in...

Carbohydrate digestion - mouth and stomach & pancreas and small intestine

By: HWC, Views: 6409

• Digestion of complex carbohydrates (starches and glycogen) involves: • Amylases produced by the salivary glands and pancreas. • Brush-border enzymes in small intestine. • In the mouth, amylase from the parotid and submandibular salivary glands begins carbohydrate digestion. �...

Kinetic parameters & Kinetic experiment

By: HWC, Views: 6496

Kinetics is a measure of the speed or rate of a chemical reaction. A study of kinetics allows us to determine which variables to control (temperature, reactants, catalysts) and how to vary them in order to maximize the amount of products formed and minimize the time involved. Vmax = maximum ve...

Structures that affect circulation - heart and systolic/diastolic BP

By: HWC, Views: 6593

• Heart generates blood pressure. • Arterioles produce resistance thereby regulating blood flow to tissues. • Veins store blood; kidneys regulate blood volume; both affect venous return and cardiac output. ■ Contractions of the ventricles determine blood pressure, which drives th...

Stomach peristalsis & Enterogastric reflex

By: HWC, Views: 6067

• Food enters, distending the stomach. • Stretch receptors activate enteric reflexes that promote peristaltic movements. • These movements, called mixing waves, begin to mix the food with stomach secretions. • Mixing waves force the digesting food (chyme) toward and through the pylo...
