The walls of vessels have rather significant morphological differences in the structure of the middle layer. What is the reason for the appearance of specific features of the structure of this layer in different vessels? Hemodynamic conditions O Inductive influence of vegetative ganglion neurons. Influence of organs of the endocrine system. O High levels of catecholamines in the blood. O Regulated by the central nervous system.

How would this affect BP? Is this an example of hypertension or hypotension? Part 2: The circulatory system has 5 functions. · Highlight the statements below that are only functions of the circulatory system. It carries cells that help to fight diseases. It gives structure and support to the body. It carries waste products to the urinary system. It carries carbon dioxide from cells to the lungs. It maintains body posture. It carries nutrients from the digestive system to other cells. It carries oxygen from the lungs to other cells. · The list gives some structures in the blood and circulatory system.

Why do interstitial fluids build up in the capillary beds of tissues? O the venous capillaries absorb more fluids than can be delivered by arterial capillaries O more fluid is usually released by arterial capillaries than is absorbed by venous capillaries O interstitial spaces lack dissolved proteins or other types of dissolved electrolytes O tissue cells within the capillary beds tend to expel fluids into nearby open spaces Next
Nifedipine is an antihypertension medication that is also used to reduce the workload on the heart. The study below compares the effects of two different types of capsules used to administer the drug to patients (GITSred line, and Cotracten Xblue line). Each graph shows changes with time following initial administra- tion of the capsules. Figure A compares the levels of nifedipine in the blood with each capsule type. The ability of the different cap- sules to reduce workload on the heart by altering blood pressure or heart rate is shown in Figures B and C, respectively. Are elevated plasma levels of nifedipine(above 10 ng/mL) required for the drug to perform its actions? Source: M. J. Brown and C. B. Toal. 2008.

As blood goes from the left ventricle through the arteries and veins of the human body, both its speed and pressure change. The arteries and arterioles can either constrict, reducing the area, or dilate, increasing the area, in response to certain conditions. Both of these changes can affect blood flow and blood pressure. An artery can also develop a permanent narrow area (stenosis) or a permanent wide area (aneurysm). Both of these changes can have significant health consequences. Suppose that in response to some stimulus a small blood vessel narrows to 90% of its original diameter. If there is no change in the pressure across the vessel, what is the ratio of the new volume flow rate to the original flow rate?A. 0.66 B. 0.73 C. 0.81 D. 0.90

You’re flowing around the circulatory system and you come across several nice but directionallychallenged travelers that have lost their way. They know where they are and where they need to go, butthey don’t know how to get there. Give basic directions using major vessels (arterial or venous) to get themwhere they need to go.a. Fred Blood Cell needs to get from the left thigh to the right atrium.b. Harry the Hormone wants to visit his buddies in the anterior pituitary, but he doesn’t knowhow to get there from the aorta.c. Eric the Erythrocyte needs to get from the left ventricle to the left deltoid.d. Betty White Blood Cell is in the right lung but has a hot date with a pathogen in the rightforearm.
