Exam 15: Blood Flow and the Control of Blood Pressure

Three tissues-________,________,and ________-do NOT have traditional capillaries.Instead,they have modified vessels called ________ that are (wider/narrower)than a capillary.

________ refers to the mass movement of fluid between the blood and the interstitial fluid as the result of ________ or ________ pressure gradients.If the direction of bulk flow is into the capillary,the fluid movement is called ________.If the direction of flow is out of the capillary,the fluid movement is known as ________.

Describe what a nurse hears through the stethoscope while using a blood pressure cuff,and explain the significance of the sounds.

Fainting is also known as

The rapid pressure increase that occurs when the left ventricle pushes blood into the aorta can be felt as ________.

If a person has a blood pressure of 120/80,her mean arterial pressure would be

________ are also known as the pressure reservoir of the cardiovascular system.

The structures that regulate blood flow into single capillaries within a tissue are ________.

The continual movement of fluid through the interstitial space functions to

Smooth muscle is present in the walls of

A rupture of a blood vessel in the brain is called ________ and may cause the loss of neurological function commonly called ________.

The endothelium of the blood vessels and its adjacent connective tissue make up the ________,which is surrounded by layers of smooth muscle and connective tissue called ________.

When the baroreceptor reflex is triggered by a decline in blood pressure,

Arthur's peripheral resistance has increased by 10%.To prevent his mean arterial pressure from changing,what factor must change to compensate,and by how much?

Calculate the pulse pressure for each example listed. A.a person with a blood pressure of 120/80 mm Hg B.a person with a blood pressure of 130/95 mm Hg

Capillary exchange involving movement between the endothelial cells is called the ________ pathway.

One of the most common signs of polycystic kidney disease is hypertension in an otherwise seemingly healthy individual.Why would cysts on the kidney lead to higher blood pressure?

Capillaries lack smooth muscle and elastic or fibrous tissue reinforcement.Instead,their walls consist of ________,supported on a cellular matrix called ________.

The only blood vessels whose walls permit exchange between the blood and the surrounding interstitial fluids are the

During the fight-or-flight reaction,________ is released from the adrenal medulla and binds to ________ receptors,found on the vascular smooth muscle of heart,liver,and skeletal muscle arterioles and results in (increased/decreased)blood flow to these organs; the same hormone binds to ________ receptors on other tissues,causing (increased/decreased)blood flow to these organs.
