Lab 4: Blood Vessel Anatomy & Histology

Question 1

What happens to the mean arterial pressure after exercise?

Answer 1

It increases, seen by a significant (>5%) positive percent change increase.

Question 2

What are the arteries of the superior regions of the body and what do they supply with blood?

Answer 2

Pulmonary trunk (lungs) & R/L pulmonary a. (lungs)
Ascending aorta (body), arch of the aorta (body), intercostal arteries (thoracic region), descending thoracic aorta (inferior region of body: thoracic, abdominal, pelvic, legs), brachiocephalic a (R arm & head) –> R common carotid a. (head), R subclavian a. (R arm), L common carotid a. (L head), L subclavian a. (L arm), L/R axillary artery (L/R arm), L/R brachial artery (L/R arm)

Question 3

What are the arteries of the inferior regions of the body and what do they supply with blood?

Answer 3

Abdominal aorta (abdominal, pelvic, legs), celiac trunk (stomach, liver, spleen), gastric a (stomach), hepatic a (liver), splenic a (spleen). superior mesenteric a. (superior intestine- mesenteric tissue), R/L renal a. (kidneys), R/L gonadal (testicular/ovarian) a. (gonads (testes/ovaries). inferior mesenteric a. (inferior intestine) R/L common iliac a. (Pelvic & legs), R internal iliac a. (pelvic), R. external iliac a. (leg), R. femoral a. (leg) [same for L side]

Question 4

What are the veins of the superior regions of the body and what do they drain of blood?

Answer 4

R/L pulmonary v. (lungs), superior vena cava (head, arms), R/L brachiocephalic v. (head, arms) –> R/L internal jugular v. (head), R/L external jugular v. (head), R/L subclavian v. (arm), L axillary v (arm), R/L brachial c. (arm), R/L Median cubital vein (arm), azygous vein (thoracic cavity to S.V.C),

Question 5

What are the veins of the inferior regions of the body and what do they drain of blood?

Answer 5

Inferior vena cava (drain inferior body), R/L renal vein (kidneys), hepatic portal (capillary-capillary, from stomach, intestine, & liver to IVC), R/L gonadal (testicular/ovarian) v. (gonads/testes/ovaries), L/R common iliac vein (pelvic, leg) , L/R internal iliac v (pelvic), L/R external iliac vein (leg), L/R femoral v (leg)
