List 4 functions of Angiotensin 11.
|
1. Stimulates aldosterone causing Na+ retention and K+ loss.
2. Stimulates secretion of ADH 3. Stimulates thirst 4. Stimulates cardiac output. |
|
|
The effect of angiotensin 11 on blood pressure is 4-8X greater than that produced by norepinephrine. TRUE/FALSE
|
TRUE.
|
|
|
ANP(right atrium) and BNP(ventricular muscle) peptide hormones reduce blood volumes and pressure by increasing Na+ ion excretion. TRUE/FALSE
|
TRUE. Their actual locations of action are within the hypothalamus and brain stem.
|
|
|
How is cardiac output related to cardiac reserve regarding a highly trained athlete?
|
The person with a larger stroke volume has a slower heart rate. An athlete at rest can maintain normal blood flow to peripheral tissues at a herat rate as low as 32bpm(increase as much as 50% higher than non-athletes).
|
|
|
What is coronary blood flow at rest?
|
It is app. 250ml/min. When the workload increases, local factors such as reduced O2 levels and lactic acid production dilate the coronary vessels and increase blood flow.
|
|
|
If the blood pressure in pulmonary capillaries rise above 25mm/Hg, fluid enters the alveoli, causing pulmonary edema. TRUE/FALSE
|
TRUE.
|
|
|
List 4 arteries that comprise the cerebral arterial circle?
|
1. anterior communicating
2. Ant. cerebral 3. Posterior communicating 4. Posterior cerebral. |
|
|
What is the most common site of a cerebral stroke?
|
Middle cerebral artery
|
|
|
List three arteries that branch off of the Celiac trunk.
|
1. left gastric
2. splenic 3. common hepatic |
|
|
What is the Azygos vein?
|
It is a major tributary of the superior vena cava. It ascends from the lumbar region to enter the thoracic cavity through the diaphram. on the left side, the azygos receives blood from the smaller hemiazygos vein which drains into the brachiocephalic vein through the highest intercostal vein.
|
|
|
List 5 congenital cardiovascular problems.
|
1. Patent ductos arteriosus/Patent foramen ovale.
2. Ventricular septal defect 3. Tetralogy of Fallot 4. Transposition of great vessels 5. Atrioventricular septal defect |
|
|
What are the 4 irregularities of Tetralogy of Fallot?
|
1. Pulmonary stenosis
2. PDA 3. Enlarged right ventricle 4. Ventricular septal defect. |
