BIO 208: A&P - CARLA 14
| Question | Answer |
|---|---|
| During increased exercise venous return | increases |
| Blood osmotic pressure is most affected by changes in the | concentration of plasma proteins |
| Elderly individuals usually have what kind of arteries | stiff and inelastic |
| Edema would be likely to form when blood osmotic pressure at the capillary | decreases |
| The vessels that permit exchange of materials between the cells and the blood are termed | capillaries |
| Blood pressure is highest in which of the following structures? | artery |
| Which of the following is greater the normal blood volume of the arterial system or the venous system? | venous |
| Which of the following would have the greater effect on peripheral resistance? | decreasing the diameter by ½ |
| What will result in decreased blood flow to a tissue? | decreased vessel diameter |
| Blood flow through a capillary is regulated by the | precapillary sphincter |
| Baroreceptors that function in the regulation of blood pressure are located in | the carotid sinus |
| The only blood vessels whose walls permit exchange between the blood and the surrounding interstitial fluids are the | capillaries |
| The muscular layer of blood vessels is the | tunica media |
| The blood vessels that play the most important role in the regulation of blood flow and blood pressure are the | arteries |
| Compared to arteries, veins | have thinner walls |
| Is blood flow faster along the walls of a blood vessel or in the center of a large vessel? | Center |
