Cardiac physiology
Filtration occurs here
What is Glomerulus
duodenum, jejunum, ileum
What is contracting
What kind of nephrons make up the majority of our nephrons
What is cortical nephrons
How does sympathetic and parasympathetic innervation affect the heart?
What is Sympathetic increases HR, parasympathetic decreases HR
What the proximal tubule is mostly responsible for
Reabsorption of filtered water
The enzyme in the saliva that breaks down carbohydrates
What is salivary amylase
The substance that type 2 alveoli cells secrete to reduce surface tension with the lungs
What is surfactant
The three main deteminants of resistance in a vessel
What is blood viscosity, vessel length, vessel radius
The terms for when the heart is relaxing and contracting
What is systole and diastole
The two main types of nephrons
What is cortical and juxtamedullary nephrons
Sympathetic- reduces peristalsis and stimulates contraction of the sphincters
Parsympathetic- Stimulates many of the digestive organs
What happens to the pressure of the lungs during inspiration and expiration
inhalation: increasees lung volume, decreases pressure
exhalation: decreases lung volume, increases pressure
What antigens and antibodies type AB blood would have
Both A and B antigens, No antibodies
How do we get from arteries to veins? Include where the capillaries are in this flow. Where is pressure highest and lowest?
Pressure is higher in arteries, lower in veins
What the collecting duct specifically does
What is reabsorbs H2o and concentrates urine
The process of a one way moving tract through the digestive system
What is peristalsis
Type 1 alveolar cells are responsible for this
What is gas exchange
The specialized cells that you would find in the SA or AV node
Autorhythmic cells
Describe the electrical conduction pathway through the heart
What is SA node- AV node- bundle of His- L and R bundle branches- perkinjie fibers
The formula for determining the urinary excretion of a substance
What is amount filtered- amount reabsorbed + amount secreted = amount of solute excreted
Secretions of the following: Mucus, Pariteal cells, cheif cells, ECL cells, G cells, D cells
Goblet cells, HCL acid, pepsinogen, histamine/seratonin, gastrin, somatostatin
The change in lung volume per change in transpulmonary pressure
What is compliance
Describe boyles law
Pressure of a gas is inversely proportional to volume
