BV + Respiratory
Blood Vessels Exam 2
| Question | Answer |
|---|---|
| Tunica Intima | Vascular endothelium Want it to stay smooth and slick |
| Atherosclerosis | heart |
| Arteriosclerosis | body |
| Tuinca Media | Smooth muscle Thicker in arteries |
| Why do we take BP in arteries | they're more pressurized |
| Tunica Externa | Made of collagen |
| Top number in BP | systolic pressure (120) |
| Bottom number | diastolic pressure (80) |
| Baroreceptor | sense pressure changes in the environment |
| Kidneys affect on BP | When you urinate you’re decreasing BP and blood volume |
| Renin | Converts angiotensinogen to angiotensin 1 |
| ACE | converts angiotensin 1 to angiotensin 2 |
| Atrial Natriuretic Peptide | Causes you to lose sodium Decrease blood pressure |
| Blood hydrostatic pressure | Push it out on the arterial end of the capillaries to bring fluid into our tissues |
| Blood osmotic pressure | Albumin causes this to take place venous end pulls fluid in |
| 3 Unpaired Cartilages: | Thyroid Cartilage Cricoid Cartilage Epiglottis |
| 3 Paired Cartilages: | Cuneiform Cartilage Cornicuate Cartilage Arteynoid Cartilage |
| External Respiration | O2 goes from Alveoli → Blood Capillaries CO2 goes from Blood Capillaries → Alveoli |
| Haldane Effect | in lungs, oxygen kicks off CO2 |
| Surfactent | Prevents alveoli from collapsing |
| Internal Respiration | O2 Blood capillaries → tissues CO2 Tissues → Blood capillaries |
| Bohr’s | in tissues CO2 kicks oxygen off of hemoglobin |
| Air is ___% Oxygen and ___% Nitrogen | 20%, 80% |
| Boyle law | when volume goes up pressure goes down (inverse relationship) |
| PN tells diaphragm to go down when you breath in | Increase in volume, decrease in pressure |
| PN tells diaphragm to go up when breath out | Decrease in volume, increase in pressure |
| CO2 mostly transported through: | 70% Bicarbonate (buffer) 20% on hemoglobin The rest is in plasma |
| Tidal Volume | air moved into and out of the lungs with each breath |
| inspiratory reserve volume | air that can be inspired forcibly beyond tidal volume |
| expiratory reserve volulme | air that can be forcibly expired beyond tidal volume |
| residiual volume | air that always remains in the lungs |
| Vital capaity: | TV + IRV + ERV |
| Total Lung Capacity | All TV + IRV + ERV + RV |
| Vaso___________ increases BP | Vasoconstriction |
| Vaso____________ decreases BP | Vasodilation |
