b. from the heart to the fingers of the r. hand
c. from the heart to the liver
d. from the heart to the spleen
e. from the heart to the pelvis
f. from the heart to the large intestine
g. from the heart to the feet
ii. trace the path of blood from the specified location to the heart, naming every vessel that is traversed
a. right calf to the heart
b. left kidney to the heart
c. left ovary to the heart
d. small intestine to the heart
e. spleen to the heart
f. left forearm to the heart
iii. trace the path of blood from location a to location b
a. left side of brain to the right thigh
b. right side of the neck to the right armpit
c. left foot to the right foot
d. right finger to the left kidney

Explanation:

For part I, blood leaves the heart via the aorta which branches into arteries that supply blood to different regions. For example, for the left hand, it goes through the aortic arch, left subclavian artery, etc. For part II, de - oxygenated blood returns to the heart through veins such as the vena cava. For part III, the blood must travel through the systemic and pulmonary circuits as needed to get from one location to another, passing through major arteries, veins, and the heart itself.

Answer:

I.
a. Aorta → Aortic arch → Left subclavian artery → Left axillary artery → Left brachial artery → Left radial and ulnar arteries → Digital arteries
b. Aorta → Aortic arch → Right subclavian artery → Right axillary artery → Right brachial artery → Right radial and ulnar arteries → Digital arteries
c. Aorta → Celiac artery → Hepatic artery
d. Aorta → Celiac artery → Splenic artery
e. Aorta → Common iliac artery → Internal iliac artery
f. Aorta → Superior mesenteric artery
g. Aorta → Common iliac artery → External iliac artery → Femoral artery → Popliteal artery → Anterior and posterior tibial arteries

II.
a. Small saphenous vein or great saphenous vein → Popliteal vein → Femoral vein → External iliac vein → Common iliac vein → Inferior vena cava
b. Renal vein → Inferior vena cava
c. Ovarian vein → Inferior vena cava
d. Superior mesenteric vein → Hepatic portal vein → Hepatic veins → Inferior vena cava
e. Splenic vein → Hepatic portal vein → Hepatic veins → Inferior vena cava
f. Basilic vein or cephalic vein → Axillary vein → Subclavian vein → Brachio - cephalic vein → Superior vena cava

III.
a. Internal carotid artery or vertebral artery (left side of brain) → Heart (through systemic circulation) → Aorta → Common iliac artery → External iliac artery → Femoral artery (right thigh)
b. Carotid artery (right side of neck) → Heart (through systemic circulation) → Aorta → Axillary artery (right armpit)
c. Great saphenous vein or small saphenous vein (left foot) → Heart (through systemic circulation) → Aorta → Common iliac artery → External iliac artery → Femoral artery → Popliteal artery → Anterior and posterior tibial arteries (right foot)
d. Digital veins (right finger) → Radial and ulnar veins → Brachial vein → Axillary vein → Subclavian vein → Brachio - cephalic vein → Superior vena cava → Heart → Aorta → Renal artery (left kidney)
