The blood vessels

Question 1

What are the major types of blood vessels

Answer 1

Arteries, arterioles, capillaries, venules, veins

Question 2

What the difference in the blood vessels structure

Answer 2

Basic structure has three layer: tunica interna (the innermost layer, adjacent to the lumen)
Tunica Media: Middle layer, smooth muscle and elastic fibres,
Tunica Externa: outmost layer, adjacent to surrounding tissue.

Question 3

Define Angiogenesis

Answer 3

is the developments of new blood vessels

Question 4

Define arterioles

Question 5

Define anastomosis

Answer 5

is the union of the branches of two or more arteries supplying the same region of the body
Provide an alternate route for blood flow

Question 6

Define necrosis

Answer 6

the death of most or all of the cells in an organ or tissue die to disease, injury, or failure of the blood supply

Question 7

Define transcytosis

Answer 7

the exchange between plasma and interstitial fluid

Question 8

Describe why valves are important in circulation

Answer 8

Ensure one way flow in veins

Question 9

What are Arteries and arterioles?

Answer 9

THEY CARRY BLOOD AWAY FROM THE HEART & TISSUE
Arteries walls are elastic, allowing them to absorb pressure created by ventricles of the heart
Smooth therefore regulate diameter

Question 10

Where does exchange take place?

Answer 10

In the capillaries. They are so thin that they permit exchange of nutrients and wastes between blood and tissue cells

Question 11

What are veins and Venules?

Answer 11

VEINS CARRY BLOOD TOWARD THE HEART
Venules -
small vessels that are formed by the union of several capillaries
Thin exchange epithelium
Drain blood from capillaries into veins

Veins-
Thin walls of vascular smooth muscle
More numerous then arteries
Lie closer to body surface
Less elastic tissue and less smooth muscle than arteries
