Definition
CO2 levels rise in body, the need to exhaled is cued Increased levels of CO2 in the body cause the brain to send a signal to the breathing muscles: the diaphragm & the inter stale. Movement of these muscles expands the chest & creates negative pressure causing the lungs to expand & air to enter thru airway. |
|

Term
|
Definition
Tiny capillaries where gas exchange occurs. Capillaries release CO2 (cellular waste) into alveoli & blood cells absorb O2 which turns them bright red arterial blood. Increase level of CO2 in alveolar sacs signals the body to exhale. |

Term
|
Definition
Active breathing, diaphragm contracts by flattening out & pulling down the abdomen; the intercostals muscles contract & open up the rib cage or thoracic cavity. Increased volume inside the vacuum of thoracic cavity, creates neg pressure, lungs expand, & fill a vacuum, air flows into the lungs thru airways |
|

Allergic reaction or reaction to stress that causes the smooth muscle of bronchioles to contract; referred as bronchi spasm. Constricts the airway & may even completely block them. Production of excessive mucous can also block the airway further. The resulting symptoms can include coughing, wheezing, hypoxia & increased respiration respiration rate. Patient is likely be using accessory muscles to try to catch their breath, but are actually trying to expel trapped air. Asthma can be treated w brochodilater inhaler, since in an allergic reaction, epinephrine in inhaled form may be administered by med practitioners. |

Heart, arterial system & the venous system Heart acts as pump that pushes blood to the lungs & then out thru the arteries, to arterioles & then capillaries where oxygenated blood is picked up by the cells. Arteries r under pressure & have smooth muscle in their lining to help move blood along the capillaries. Capillaries r midpoint between the arteries & veins at both the lungs & cellular level. Their twin walls allow for gas exchange, & the delivery of nutrients & the removal of waste products. Veins: venous system low pressure, thin walls, w/out musculature.Venous system consists of veins, venues, & capillaries. Capillaries deliver deoxygenated blood to venues where it is moved along to the veins, carries blood bk towards the heart for re-oxygenation & removal of CO2. |

2 aground, 2 ventricles. Atria receive blood, ventricles send blood.right atrium receives deoxygenated blood fr the Vena Cava, which is the final vein of the circulatory system. Blood moves thru the tricuspid atrioventricular valve into the right ventricle. Right ventricle pumps blood into the lungs the the pulmonic valve via pulmonary artery. Oxygenated blood returns to hrt thru left atrium, flows down thru the mitral valve to the left ventricle & is pumped out thru the aorta thru to thebrest of the body via arteries. |

Conduction system of the heart |
|
Definition
Small % of cardiac muscle cells are auto rhythmic in that they contract continually, setting the beat for the rest of the heart muscle. SA node produces electrical charge at top of rt atrium, produced by their contraction then moves to the Atrioventricular (AV) node, which lies on the wall between the rt atrium & rt ventricle. Signal produced in AV node is sent down the atrioventricular bundle, aka bundle of his, which lies between 2 branches are purkinje fibers, wh initiate the contraction of the ventricles fr the bottom up. The result is recognizable double beat of the heart w the contraction of the atria staggered slightly, but perfectly fr that of the ventricles. |

Blood supply to heart muscle is blocked. Usually occurs @ left ventricle & results in damage to cardiac muscle.left ventricle pumps blood to rest of body, & receives oxygenated blood from the lungs via the right atrium. When it's musculature isn't working, blood pools in the left ventricle-called congestive hrt failure (CHF) & result in death. Symptoms:SOB, increased hrt rate, chest noises will be heard as blood & fluid accumulate in lungs. |

AMI -acute myocardial infarction |
|
Definition
Result of hrt muscle not receiving blood due to a blockage of coronary arteries. As soon as blood supply to the hrt muscle or myocardial tissue stops, the tissue begins to die & this impairs the gets ability to pump blood. Symptoms of hrt attack: tightening sensation or pain w/in the chest which can radiate out to the left arm, neck, & jaw. Patient can feel faint, nauseous & or short of breath. Pale, & damp skin, pulse rapids, slow or irregular, there will be a change in BP. |
|

Term
|
Definition
Consequence of hrt attack, shock is physiological state of a body w/out enough blood supply. Tissue damage caused by initial hrt attack is spread due to the inefficiency of the muscle near the damaged area. The results similar to CHF as the hrt is unable to distribute the blood it receives, which builds up & backs up into the lungs. |

Definition
Chest pain that results in partial blockage of coronary arteries leads to poor blood supply to heart muscle. Reduced blood supply depletes oxygen available to the muscle cells ( hypoxia) & makes it hard for them to contract. Cramp in heart muscle, commonly occurs during times of physical stress when the heart is working hard & needs more oxygen. Heart attack is complete blockage. Angina pain can be alleviated w nitro. |
