Heart and lungs 1
cardiovascular system and respiratory system
| Question | Answer |
|---|---|
| The Heart | located primarily under the sternum with 1/3 on the right and 2/3 on the right |
| Epicardium | visceral pericardium |
| Myocardium | contains thick bundles of cardiac muscle twisted into ringlike arrangements |
| Endocardium | thin sheet of endothelium that lines the heart chambers |
| Atria | receive blood |
| Ventricles | discharge blood |
| Atriventicular Valve (AV) | prevent back flow from the ventricle into the atrium during contraction |
| Semi lunar Valve | guard the exits into the large arteries from the ventricles and separate the ventricles from the arteries |
| Cardiac Output (CO) | amount of blood pumped out by each side of the heart in 1 minute |
| Heart Rate | number of beats that heart makes in 1 minute |
| Stroke Volume | the volume of blood pumped with each heart beat |
| Blood Pressure | the pressure he blood exerts against the inner walls of the blood vessels, this force is what keeps the blood flowing between heart beats |
| Pulmonary Respiration | air must move into and out of the lungs so that gases in the air sacs of the lungs are constantly refreshed. |
| External Respiration | gas exchange between the pulmonary blood and the alveoli must take place between the blood and the body exterior |
| Respiratory Gas Transport | O2 and CO2 must be transported to and from the lungs and tissue cells of the body via the blood stream, |
| Internal Respiration | gas exchange must be between the blood and tissue cells. gas exchanges are occurring between the blood and the cells inside the body. |
| Inspiration | diaphram and external intercostals contract increasing the size of the thoracic cavity. |
| Expiration | passive process as a result in a relaxation of the diaphram and intercostal muscles |
| Tidal Volume (TV) | normal breathing moves approx. 500 ml of air about a pint in and out of the lungs |
| Inspiratory Reserve Volume | Volume of room that a person can inhale with force, which is about 2000-3000 ml |
| Expiratory Reserve Volume | left over air after normal breathing this can be exhaled with force about 1200 ml |
| Residual Volume | even after a forced exhale there is some left over volume about 1200 ml |
| Vital Capacity | total amount of exchangeable air, usually 4800 ml |
| Total Lung Capacity | 6000 ml |
| Medulla | controls rhythm, typically between 12-15 RPM. also controls respiration |
| Pons | smooth out the basic rhythm of inspiration and expiration |
| Bronchitis | inflammation of the bronchi |
| Emphysema | destruction of alveolor walls causes hardening of lung tissue |
| Cystic Fibrosis | most common genetic disease causes oversecreation of a thick mucus that clogs respiratory passages and puts a high risk for infection |
| Blood Plasma | transfers CO2 back into the lungs |
| Pulmonary Artery | carries blood from heart to lungs |
| Parietal Pleura | outermost lining of the lungs |
| Visceral Pleura | innermost lining of the lungs |
| hemoglobin | carries O2 in the blood |
| Pulmonary Vein | carries blood from lungs to heart |
| Cardiac Cycle | one complete heart beat |
| Senatorial Node | Pacemaker of the heart |
| Chordea Tendinae | keeps the AV valve from collapsing |
| Brain Stem | portion of the brain that regulates breathing |
