Cardio-Physio-Microcirculation & Lymphatics

Question 1

What type of blood vessels are generally are found in clusters?

Answer 1

Capillairies in capillary beds

Question 2

Blood flow to tissue through capillary bed is known as?

Answer 2

tissue perfusion

Question 3

The primary role of the is to return excess interstitial fluid to the cardiovascular system after filtration through lymph nodes.

Answer 3

lymphatic system

Question 4

What are the main areas of drainage for the lymphatic system?

Answer 4

Areas of drainage served by the thoracic duct and the right lymphatic duct

Question 5

What is the role of the lymphatic system in the immune system?

Answer 5

serving in the maturation and circulation of immune cells and filtration of lymph.

Question 6

Lymphatic organs are involved in what 3 main type of duties?

Answer 6

development, storage, and function of immune cells (primarily lymphocytes) produced in the bone marrow

Question 7

Flow of blood that takes place within body’s capillary beds is collectively called?

Answer 7

microcirculation

Question 8

Flow of blood that takes place within body’s capillary beds is collectively called microcirculation; involves two types of vessels:

Answer 8

1. True capillaries: where materials are exchanged
2. central vessels (slightly large capillaries also called preferential or thoroughfare channels).

Question 9

What forms interweaving networks with multiple anastomoses; fed by proximal end of central vessel, which is formed by either small terminal arteriole or metarteriole?

Answer 9

True capillaries

Question 10

Each capillary-metarteriole junction contains; controls amount of blood flowing into capillaries

Answer 10

precapillary sphincter

Question 11

In the capillaries (called preferential or thoroughfare channels) the blood flow is continuous, and in the capillaries (called the true capillaries) blood flow is intermittent.

Answer 11

large; small

Question 12

At rest, what percent of body’s capillary beds are fully open?

Answer 12

25%

Question 13

walls consists only of endothelium rolled into tube and small amount of basal lamina secreted by endothelial cells.

Answer 13

Capillary

Question 14

What are cells found around some capillaries; have contractile filaments and appear to control blood flow through capillary?

Answer 14

pericytes

Question 15

Walls of most capillaries consist of 1–3 cells joined by tight junctions; curl around capillary’s entire circumference.

Answer 15

endothelial
