the basilar artery which is formed by the union of vertebral and subclavian arteries

Question 17

what is the external jugular vein?

Answer 17

the external jugular vein contains the blood that drains from the face and the scalp. it then empties to the subclavian vein

diaphragm

Question 22

what veins supply the thorax?

Answer 22

the right and left brachiocephalic veins which join at the superior vena cava which returns the blood to he right side of the heart.

the 3 anterior branches supply them

Question 24

what supplies the foregut?

Answer 24

Answer 28

the lumbar artery supplys the blood to the body wall

Question 29

what does the abdominal aorta bifurcate to?

Answer 29

it bifurcates into the common iliac artery. the external iliac supplies lower limb and the internal iliac supplies the pelvic organs.

Question 30

what veins are found in the abdomen?

Answer 30

the external and internal iliac vein from the lower limb and pelvis join to make the common iliac vein. The right and left common iliac veins join and join the inferior vena cava.

Question 31

what other veins connect to the inferior vena cava?

Answer 31

suprarenal vein
renal veins
right gonadal vein
lumbar veins

Question 32

where does the left gonadal empty?

Answer 32

it empties straight into the left renal vein

Question 33

what is the hepatic portal system?

Answer 33

its where nutrient rich/ oxygen poor blood is drained from the gut into the livers capillaries.

Question 34

what veins are involved in the hepatic portal system?

Answer 34

the inferior mesenteric vein drains into the splenic vein that joins with the superior mesenteric vein, which then drains into the hepatic vein then into the vein then into the hepatic veins and finally into the inferior vena cava

Question 35

what are the arteries in the lower limb?

Answer 35

it starts with a branch of the common ilia the external lliac artery then it becomes the femoral artery it branches into profunda femoris artery which is a deep vein that supplies the posterior structure. then becomes the popliteal artery behind the knee joint

Question 36

what arteries supply the lower part of the lower leg?

Answer 36

the popliteal artery splits into the anterior tibial artery which goes into the dorsalis pedis. and the posterior tibial artery which becomes medial and lateral planta artery.
