6 Anatomy of the circulatory system

Question 1

Anterior

Answer 1

Ventral/front

Question 2

Posterior

Answer 2

Dorsal/back

Question 3

Superior

Answer 3

Towards the sky

Question 4

Inferior

Answer 4

Towards the ground

Question 5

Medial

Answer 5

Closer to the midline

Question 6

Lateral

Answer 6

Further from the core (the thumb is lateral to the pinky)

Question 7

Distal

Answer 7

Further from the core vertically (head is distal to the neck)

Question 8

Proximal

Answer 8

The shoulder is proximal to the elbow (closer to the core vertically)

Question 9

What does the Circ System transport

Answer 9

O2
waste
WBC's 
Hormones 
Nutrients

Question 10

Name the different circ systems:

Answer 10

Blood:

• cardiac
• pulmonary
• systemic

Specialised

• portal
• foetal

Lymph

Question 11

Which blood Circ Systems are high pressure?

Answer 11

systemic and cardiac

Question 12

Cephalic

Answer 12

Head

Question 13

Popliteal fossa

Answer 13

Knee pit

Question 14

Axillary fossa

Answer 14

elbow pit

Question 15

Name 7 pulses:

Answer 15

• brachial
• radial
• carotid
• popliteal
• posterior tibial
• dorsal pedilis
• femeral

Question 16

Which blood circ systems are low pressure?

Answer 16

pulmonary

Question 17

What is portal circulation?

Answer 17

Artery –> capillary bed –> portal vessel –> capillary bed –> vein

Question 18

Name the portal circulatons

Answer 18

• hypothalamus –> pituitary (takes hormones) -hypophyseal

- hepatic

Question 19

Talk me through the hepatic portal vein thingy

Answer 19

-spleen, LI, SI, stomach and pancreas all drain into the hepatic portal vein taking the nutrient rich blood to the liver

Question 20

Foetal circulation:

Answer 20

GI, lungs and liver aren’t fully developed so they are bypassed

Question 21

Lymphatic circulation consists of

Answer 21

• a network of lymph vessels
• lymph
• lymph nodes (filter blood and detect infection)
• lymph tissues and organs

Question 22

Features of lymph capillaries:

Answer 22

• more leaky than regular ones so can take up plasma proteins
• dead ended
• adjacent to capillary beds

Question 23

What are the functions of the lymph system?

Answer 23

• play a role in immune response

- drainage of extra interstitial fluid left behind at capillary beds (15%)

Question 24

What would we get without the lymph system?

Answer 24

oedema

Question 25

once the ISF enters the lypmh vapillary:

Answer 25

It is called lymph

• travels through afferent vessels to nodes to efferent vessels to lymph trunks –> right lymphatic duct
• –>thoracic

Question 26

Where does the right lymphatic duct drain to

Answer 26

Right side of:
head
neck
thorax and upper limb (arm)

Drains to right subclavian vein

Question 27

where does the thoracic duct drain to ?

Answer 27

-everything else

drains to left subclavian vein
