Blood – Physical Characteristics

A

• Sticky, opaque fluid with a metallic taste
• Color varies from scarlet to dark red.
• Blood is denser than water and about five times
more viscous, largely because of the formed
elements.

A

Dorsalis pedis

166
Q

Three major types of veins

A

Venules
Small and medium veins
Large veins

167
Q

similar to a structure of capillaries but slightly larger in diameter.

A

Venules

168
Q

It is composed of endothelium resting
on a delicate connective tissue layer.

A

Venules

169
Q

the only present tunic resting on a delivate layer of dense connective tissue

A

Tunica intima

170
Q

all the tunics are evident.

A

Small and medium veins

171
Q

contains circular smooth muscle.

A

Tunica media

172
Q

determines the capability of the vein to
distend.

A

Tunica adventitia

173
Q

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.

A

Large veins

174
Q

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

A

Superior vena cava

Inferior vena cava

175
Q

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

A

Superior vena cava

176
Q

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

A

Inferior vena cava

177
Q

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

A

External jugular

178
Q

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

A

Internal jugular

179
Q

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

A

Brachial

180
Q

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

A

Cephalic

181
Q

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.

A

Basilic

182
Q

The vein wherein brachial, cephalic and basilic
veins empty.

A

Axillary

183
Q

connect cephalic to basilic vein

A

Median cubital

184
Q

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

A

Brachiocephalic

185
Q

the posterior intercostal veins and drain into the
azygos vein.

A

Azygos

186
Q

Carry blood from the kidneys

A

Renal

187
Q

Carry blood from the Adrenal Glands

A

Suprarenal

188
Q

Carry blood from the testes (Male)
and ovaries (Female)

A

• Testicular
• Ovarian

189
Q

Carry blood from the back and abdominal wall

A

Lumbar

190
Q

Drains the entire small intestine, part of the large
intestine and stomach

A

Superior mesentric

191
Q

Drains the distal portions of the large intestine and
rectum and joins the splenic vein just before that
vessel unites with the superior mesenteric vein to
form the hepatic portal vein

A

Inferior mesentric

urinary bladder, rectum, uterus, and vagina. These
veins unite with the external iliac veins to form the
common iliac veins which empty into the inferior
