BLOOD VESSEL | VEINS

Question 1

Three major types of veins:

Answer 1

Venules, small and medium veins, large veins

Question 2

similar to a structure of capillaries but slightly larger in diameter. It is composed of endothelium resting on a delicate connective tissue layer. Tunica intima is the only present tunic.

Answer 2

Venules

Question 3

all the tunics are evident. The tunica media contains circular smooth muscle. The tunica adventitia determines the capability of the vein to distend.

Answer 3

Small and medium veins

Question 4

similar to a structure of capillaries but slightly larger in diameter. It is composed of endothelium resting on a delicate connective tissue layer. Tunica intima is the only present tunic.

Answer 4

Venules

Question 5

all the tunics are evident too. It has a pre-dominant tunica adventitia and its tunica media is thin but has the capability to regulate vessel diameter because venous pressure is low.

Answer 5

Large veins

Question 6

The two major large veins that returns blood to the heart from the regions of the body are the

Answer 6

superior vena cava and inferior vena cava.

Question 7

returns blood from the head, neck, thorax, and upper limbs to the right atrium of the heart.

Answer 7

Superior vena cava

Question 8

returns blood from the abdomen, pelvis, and lower limbs to the the right atrium of the heart.

Answer 8

Inferior vena cava

Question 9

Carry blood from the posterior Head and neck. Empties into the subclavian vein

Answer 9

External jugular

Question 10

Carry blood from the brain and Anterior Head, Face and Neck. They join the subclavian veins on each side of the body to form the brachiocephalic veins

Answer 10

Internal jugular

Question 11

Carry blood from deep structures of the upper limbs. The brachial veins empty into the axillary vein.

Answer 11

Brachial

Question 12

Carry blood from the distal forearm and bend around the radius as it travel superiorly and then continue up the lateral superficial aspect of the arm to the shoulder to join the axillary vein

Answer 12

Cephalic

Question 13

Carry blood from the distal forearm and extend along the posteromedial aspect of the forearm, crosse the elbow, and then join the brachial vein in the axilla, forming the axillary vein.

Answer 13

Basilic

Question 14

The vein wherein brachial, cephalic and basilic veins empty.

Answer 14

Axillary

Question 15

connect cephalic to basilic vein

Answer 15

Median cubital

Question 16

Carry blood from the anterior thoracic wall from the anterior intercostal veins and drain into brachiocephalic veins

Answer 16

Brachiocephalic

Question 17

Carries blood from the posterior thoracic wall from the posterior intercostal veins and drain into the azygos vein.

Answer 17

Azygos
