| Question | Answer |
|---|---|
| adequate breathing is characterized by? | Adequate respiratory rate and tidal volume |
| (Vt) is the amount of air the pt. breaths in and out with ____ regular breath | 1 |
| adults normal rate is | 8-24 per min. |
| elderly pt have ______ respiratory rates | higher |
| elderly normal rate is | 20-22 per min |
| children normal rate is | 15-30 per min |
| infants normal rate is | 25-50 per min |
| How do you characterize inadequate breathing? Give at least 6 examples | too slow, fast, irregular pattern, diminished or no sound, unequal chest expansion, pale, use of accessory muscles |
| How much of the hearts mass is located to the left of the mid-line of the body | 2/3rds |
| Double-walled sac that encloses the heart, gives support and prevents friction is called | pericardium |
| how many chambers does the heart have? | 4 |
| name the upper chambers in the heart | atria |
| what chamber receives blood from the veins? | atria |
| R-atrium receives oxygen_________ blood from the body | depleted |
| left atrium receives oxygen_______blood from the lungs | rich |
| lower chambers are called_______ | ventricles |
| what does the R- ventricle do? | pumps O2 depleted blood to the pulmonary arteries where it is then transferred to the lungs to be oxygenated |
| What does the L- ventricle do? | Pumps O2 rich blood to the aorta then to the body cells |
| name the valves of the heart | tricuspid valve pulmonary valve mirtal valve aka bicuspid valve aortic valve |
| what does the myocardium do | contracts and ejects blood from the heart |
| where does the electrical impulse in the heart originate from? | S.A node Sinoatrial |
| All arteries except _________ carry o2 rich blood | pulmonary arteries |
| The path of the electrical impulse begins at the ______ and travels to the _______ then to the____________ and ends at the _________. | SA---AV--bundle of his---purkinje fibers |
| The major artery in the heart is called what? | aorta |
| Vessels that supply the heart "itself" 1st is called what? | coronary arteries |
| located on each side of the neck and supply the brain and head with blood are called what? | carotid arteries |
| This is the major artery in the thigh and supplies the groin and leg.... | femoral arteries |
| this is a closed system, it contains the heart, blood vessels, and blood | circulatory system |
| Name some of the functions of the circulatory system | perfusion of cells removal of waste reservoir to house blood, buffering acid-base balance, delivers immune cells to fight infection promotes clotting |
| this valve sits at the base of aortic artery | aortic valve |
| this valve is between the L atrium and the L ventricle | Mitral valve or bicuspid valve |
| This valve is located in the R ventricle at the base of the pulmonary artery | pulmonary valve |
| this valve is between the R atrium and the R ventricle | tricuspid valve |
| _________ is the force extroverted by the blood on the interior walls of the arteries | blood pressure |
| _________ is the pressure against the walls of the arteries when the L ventricle contracts | systolic blood pressure |
| __________ is the pressure exerted against the walls of the arteries when the L ventricle is at rest. | diastolic blood pressure |
| _________ is force exerted on the on the inside of the vessel walls as a result of the b.p and volume | hydrostatic pressure |
| leaking fluid in to the tissue is called | edema |
| another word for SHOCK is | hypo-fusion |
| An inadequate elimination of carbon dioxide and other wastes that result from inadequate circulation of blood is called what? | hypo-fusion aka shock |
| What are the final bi products of glucose metabolism? | water and carbon dioxide |
| True or False: Aerobic metabolism means without oxygen | False: anaerobic means without oxygen. AN= without |
| Bi-products are blown off by the lungs in which metabolism? anaerobic or aerobic | aerobic |
