BLOOD TRACING PROBLEMS
BIO 205 BASIC HUMAN ANATOMY
In the following pathways, be able to list in order all arteries, veins, capillaries, valves and heart chambers through which blood flows. There may be more than one correct pathway. Just choose one.
To solve these problems, you must know blood flow through the heart and blood vessels listed in your lab manual. You must also study text diagrams and lecture notes for blood flow through the liver, myocardium, and fetal circulation.
NOTE: Start and end in capillaries. (Why?) The pattern in the answers will be the following: capillaries - veins - heart - arteries - capillaries.
Trace a drop of oxygen-containing blood from the lungs to the brain
Trace a drop of blood from a lung to the right side of the face
Trace a drop of blood from deep leg muscles to the lungs
Trace the blood pathway for waste-containing blood from the forearm to the kidney
Trace adrenalin from the adrenal gland to the myocardium
Trace the pathway for nutrient-laden blood from the small intestine to the diaphragm
Trace blood from the myocardium back to the myocardium
Trace food from the placenta to the fetal spleen
Trace waste from the fetal brain to the placenta
