| | | | | | | | | | |
would reveal elevated numbers of - CORRECT ANSWER✔✔-Eosinophils
| | | | | | | |
and basophils
|

|
2. ADP
|
3. Thromboxane A2
| |

| | | |
Place the following in order of the propagation of a cardiac action
| | | | | | | | | | | |
potential:
1. Purkinje fibers
| |
2. SA node
| |
3. Right and left bundle branches
| | | | |
4. AV bundle
| |
, 5. AV node - CORRECT ANSWER✔✔-2, 5, 4, 3, 1
| | | | | | | | |
How does one describe the relaxation period of the cardiac cycle? -
| | | | | | | | | | | |
CORRECT ANSWER✔✔-It is a time that becomes shorter as the heart
| | | | | | | | | | |
rate increases.
|
How is net filtration pressure (NFP) calculated? - CORRECT ANSWER✔✔-
| | | | | | | | |
(BHP + IFOP) - (BCOP +IFHP) = NFP
| | | | | | |
Why is less pressure needed to move blood through the pulmonary
| | | | | | | | | | |
circulation than through the systemic circulation? - CORRECT
| | | | | | | |
ANSWER✔✔-Pulmonary arteries have large diameters; pulmonary | | | | | |
arteries have thinner walls and less elastic tissue than systemic arteries;
| | | | | | | | | | |
pulmonary arteries offer less resistance to blood flow than systemic
| | | | | | | | | |
arteries.
Which of the following is not true?
| | | | | |
1. Systemic blood pressure is generated by contraction of the atria.
| | | | | | | | | |
2. A systolic pressure of 110 mmHg in a resting young adult is probably
| | | | | | | | | | | | | |
normal.
3. The pulse pressure is the difference between the systolic and diastolic
| | | | | | | | | | |
pressures.
|
4. The highest blood pressure values are observed in the aorta.
| | | | | | | | | |
