Type 1.
Definition
The cells that are thin and provide a surface for diffusion of gasses are
Term
Type 2.
Definition
Cells that secrete surfactant
Term
Surfactants
Definition
phospholipids secreted by cells in the lungs that reduces water surface tension, thus conferring lung compliance (stretch)
Term
Diaphragm & Intercostals
Definition
Two muscle systems that drive ventilation
Term
4
Definition
How many oxygen (O2) does hemoglobin bind
Term
Hemoglobin
Definition

Protein composed of 4 polypeptide chains each with an iron and has the capacity to bind O2

 

Term
Chemoreceptors
Definition
Cells sensitive to chemical in the body
Term
Apnea
Definition
Refers to cessation of ventilation
Term
Brachycardia
Definition
Will occur when we place our face in water
Term
Nephron
Definition
This is the functional unit of the kidney
Term
Filtration, Secretion, and Reabsorption
Definition
The major functional units of the Nephron
Term
Atriopeptin
Definition
Peptide hormone that is released from the atria and promotes sodium and water excretion
Term
Antidiuretic Hormone (Vasopressin)
Definition
Peptide hormone released from the posterior pituitary that causes the conservation of water
Term
Angiotensinogen
Definition
Prohormone released by the liver, that is initially acted on by rennin then converting enzyme to form its strongly hypertensive form
Term
Aldosterone
Definition
Steroid hormone released by the adrenal cortex that conserves sodium and promotes the excretion of potassium
Term
pepsin
Definition
name the enzyme of the stomach
Term
amylase
Definition
The name of the enzyme that digested starch
Term
Lipase
Definition
general name for the enzyme that digested the oil
Term
Cardiovascular center of the Medulla
Definition
Name the integration center of the hemorrhagic neural reflex arc.
Term
End Diastolic Ventricular Pressure
Definition
Venous return is increased, stroke volume is increased, what variable of stroke volume was increased
Term
Inspiratory movement, Blood Volume, Skeletal muscle pump(contraction), and Venous sympathetic nerves
Definition
4 factors that will influence venous return
Term
Lymph system
Definition
Responsible for fluid return that was not absorbed
Term
Percapillary Sphincter
Definition
The smooth muscle that regulates blood flow through the capillary
Term
MAP (Mean Aeterial Pressure)
Definition
Cadiac output * Total Peripheral Resistance
Term
Angiotensin(1, 2)
Definition
peptide hormone that regulates sodium and water balance
Term
Baroreceptors
Definition
Sensory cells (neurons) tha are senitive to blood pressure and the rate of blood pressure change
Term
Lung Compliance
Definition
The ability of the lung to stretch
Term
Inspiration
Definition
Bulk flow of air into the lungs
Term
Expiration
Definition
Bulk flow of air out of the lungs
Term
Histamine, Parasympathetic, Decrease CO2, and Some Prostaglandins
Definition
Control of Airway resistance-Constriction
Term
Epinephrine, Sympathetic, Increase CO2, and other Prostaglandins
Definition
Control of airway resistance-dilation
Term
Cooperative Binding of Hemoglobin
Definition
Refers to the sequential addition of oxygen and that the more O2 the more likely O2 will bind
Term
As an Ion (HCO3-), Complexed to Hemoglobin, Dissolved in Plasma
Definition
3 ways for the movement of CO2
Term
Peripheral Chemoreceptors
Definition
Not in the Brain
Term
Central Chemoreceptors
Definition
Within the Brain
Term
Nephron
Definition
Basic Functional Unit of the Renal System
Term
Antidiuretic Hormone, Angiotensin II, Aldosterone, and ANF (Atrial Nutriuretic Factor)- Atriopeptin II
Definition
4 hormones involved in the Renal System
Term
Atria-Heart Stretch
Definition
Results in a release of ANF from vesicles in the heart. Increases water and sodium loss
Term
Erythropoietin
Definition
Red Blood Cell Formation
Term
Digestion
Definition
Process of breaking down large particles and large molecular weight substances into smaller molecules
Term
Secretion
Definition
Process by which molecules are released by cells in response to a specific stimulus, with a specific function
Term
Absorption
Definition
Movement of materials acorss a layer of epithelial cells from a body compartment to the blood
Term
Feces
Definition
Net result of difestion, secretion, and lack of absorption (includes bacteria)
Term
Cephalic Phase
Definition
Acts by way of the Vagus nerves or gastrin, results in INCREASED HCl production
Term
Gastric Phase
Definition
Acts by way of neural reflexes gastrin results in INCREASED HCl production
Term
Intestinal Phase
Definition
Acts by way of neural reflexes secretion, decreased gastrin. Results in decreased HCl production
Term
Emulsification
Definition
Breakdown of large fat globules into smaller fat globules, with the addition of bile salts in the small intestine
Term
Lipase, Emulsification, and Mechanical agitation
Definition
3 ways digestion is accomplished
