supply paths

Question 1

whats the path of conduction cells in the heart

Answer 1

SA node, then to left atria via interatrial bundles—> internodal pathways —> AV bundle —> R&L bundle branches—> purkinjie fibres

Question 2

describe the supply path down to the legs

Answer 2

abdominal aorta–> R&L common iliac arteries—> internal and external iliac arteries, ext —–> femoral artery—->popliteal artery —-> 3 branches one is the posterior tibial artery —-> plantar arch

Question 3

where is the abdominal aorta found

Answer 3

below the heart in the abdominopelvic cavity

Question 4

describe path of the right common iliac artery

Answer 4

it goes across the pelvis, and branches into the external and internal iliac arteries

Question 5

what does the internal iliac artery supply

Answer 5

the pelvic bowl and the buttocks

Question 6

where does the external iliac artery go

Answer 6

it goes under the inguinal ligament and passes into the lower limb where it becomes the femoral artery.

Question 7

what is the span of the femoral artery

Answer 7

from groin to lower

Question 8

describe the venous drainage pathway

Answer 8

starts with the plantar venous arch vein, it then goes to the posterior tibial vein (deep), then to the popliteal vein (deep), then the femoral vein, the femoral vein goes to the external iliac veins, then the common ilac vein then to the inferior vena cava.

Question 9

arteries and veins run in pairs, so what is next to the posterior tibial artery

Answer 9

the posterior tibial vein

Question 10

why are some veins deep

Answer 10

as some veins run in conjunction with arteries. arteries are deep in the body, so some veins thus run deep

Question 11

whats the other drainage path from the plantar arch

Answer 11

the more superficial great saphenous vein

Question 12

where does the great saphenous vein run and then finish

Answer 12

ankle to groin close to the skin, in medial aspect of lower limb. it joins the femoral vein at the saphenofemoral junction.

Question 13

where does the great saphenous vein run and then finish

Answer 13

ankle to groin close to the skin, in medial aspect of lower limb. it joins the femoral vein at the saphenofemoral junction.

Question 13

why do all veins eventually go to deeper veins

Answer 13

even the more superficial veins go deep eventiually as they must run to the heart, which is deep.

Question 14

whats the drainage path for lymph vessels on right body above the belly button

Answer 14

right lymphatic duct then the right subclavian vien

Question 15

whats the drainage path for the left body plus right below the belly button for lymph vessels

Answer 15

cisterna chyli, then the left thoracic, left subclavian vein
