Learning Objectives 1. Describe the components of blood and how they contribute to the 3 functions of circulating blood. 5. Describe how the lymphatic system works in conjunction with the circulatory system.
S1: Apply scientific reasoning to biological problems.
S3: Interpret and draw conclusions from scientific data.
I. Hematopoiesis 1. (1pt) Blood cells have a limited lifespan and therefore hematopoiesis is a continually ongoing process. True or False? (Bold one)
2. (1pt) After a standard blood donation of about 500mL, hemoglobin concentration and with it the availability of oxygen in the blood drops by about 7%. It takes about 14 days until blood levels and oxygen availability are back to normal again. Use terms from the Word Bank below to fill in the blanks in the paragraph below to explain what happens during this time. Reference: https://pubmed.ncbi.nlm.nih.gov/27807869/
When blood oxygen availability drops, the _________ generates a hormone called ____________, which
stimulates ___________ cells to produce erythrocytes (red blood cells) in the ___________. Word Bank
: Not all terms will be used, and no term will be used more than once. B
Diaphysis
Erythropoietin
Growth hormone
Heart
Kidney
Liver
Antidiuretic hormone
Pluripotent stem
Spleen

T
3. (2 pts) Taking erythropoietin as a drug is banned in many sports. Why is it banned and why is it harmful to supplement your body’s natural supply with additional erythropoietin? Where can an athlete train to get a similar effect as taking erythropoietin? Answer in 2-5 sentences.

PROBLEM 2: Abdominal aorta aneurysm repair can involve the deployment of an endovascular
stent grafts as depicted in the adjacent figure. The graft is a bifurcating fabric tube supported by
a metal mesh that is designed to help prevent the aneurysm from rupturing. It is held in place by
hooks that penetrate into the surrounding tissue. The inlet diameter of the graft is 2 cm and the
outlet diameters are each 1.7 cm. The inlet blood pressure is 95 mm Hg and the inlet flow rate
of blood is 70 mL/sec. The outlet blood pressure is 90 mm Hg and the outlet flow rate of blood is
equal for both iliac arteries. If each branch of the stent makes an angle of 45 degrees with the
vertical, calculate the vertical force that the hooks exert on the tissue to remain in place. Neglect
the effects of gravity and friction between the graft and the surrounding tissue. Assume that the
flow is steady (i.e., ignore pulsing) and that the velocity profile at the inlets and outlets is uniform
across the area.…
