Q

Define orthostatic hypotension

Study These Flashcards
A

Low blood pressure that is the result of sudden body positional changes

24
Q

Name the associated anemias

Study These Flashcards
A
  • iron- microcytic
  • vit.b12- macrocytic
  • abn hemoglobin- sickle cell Ed
  • blood loos- hemorrhage
  • hemotoxins- hemolytic
  • bone marrow- aplastic
25
Low levels of circulating rbc’s does this constitute anemia yay or nay
Yay
26
Name an adaptation that allow capillaries to adjust BF
Precapillary | Sphincters
27
Which congenital disorder consists of 4 separate heart defects
Tetralogy of fallot
28
List congenital heart defect
- patent ductus arteriosus - coarctation of the aorta - tetralogy of fallot
29
Tunica media veins is thicker than that of arteries true or false
False
30
What does the Tuncia media contain
Smooth mm cells
31
Smooth mm cells describe the other 3 tunica
Tunica intima: endothelial layer only aka endothelialium Tunica adventitia: outer layer of CT & having its own blood supply vasocasorum
32
Name the stage of cardiac mm action potential that only occurs with these type of cells
Plateau
33
What ion is associated with plateau
Calcium
34
List physiological processes in which calcium is required
- blood clotting - neurotansmission - mm contraction - mineralization of bones
35
Define diastole & systole
Diastole: heart mm relaxed Systole: heart mm contracted
36
The heart is Sadi to be autorhythmic in that it can generate its own rhythm. This generation of rhythm is known as the intrinsic mechanism. Can the nervous system affect this rhythm (what branch and how)
Yes- autonomic NS can- extrinsic mechanism Parasymphatic- decrease HR & CO Sympathetic- increase HR & CO & contractility
37
What is the main fxn of valves in the cardiovascular system
Prevent back flow
38
Name the largest distributive/ conducting artery supplying the body
Aorta
39
``` Mix and match Leukocytes- erythrocytes Thrombocytopenia- epidermis Distribution- phagocytes 2nd line of defence- thrombocytes 1st line of defence- leukocytes ```
``` Leukocytes- leukocytes Thrombocytopenia- thrombocytes Distribution- erythrocytes 2nd lien of defence- phagocytes 1st line of defence- epidermis ```
40
``` Mix and match Vasodilation- av valves close Lub- deoxygenated blood from body to heart Vasoconstriction- oxygenated blood Venae cavae- SL valves close Dub- increase in BF Pulmonary veins- decrease in BF ```
``` Vasodilation- increase in BF Lub- av valves close Vasoconstriction- decrease in BF Venae cavae- deoxygenated blood from body to heart Dub- SL valves close Pulmonary veins- oxygenated blood ```
41
Define erythropoiesis
Creation of RBC’s from hemcytoblasts
42
Describe the pulmonary circulation
Pulmonary arteries/ trunk caries deoxygenated blood > lung capillaries for oxygenation/ gas exchange > pulmonary vein cries oxygenated blood back to the L atria
43
Compare and contrast hemophilia & anemia
Hemophilia: inadequate blood clotting proteins in blood Anemia: blood has unusually low oxygen carrying capacity often due to malformed hemoglobin or low levels of rbc’s- this is a symptom of homeostatic imbalance
44
``` Mix and match Tachycardia- difficulty breathing Bradycardia- blood clotting Dyspnea- slow heart rate Hemostasis- fast heart rate ```
Tachycardia- fast heart rate Bradycardia- slow heart rate Dyspnea- difficulty breathing Hemostasis- blood clotting
