Drag each label to the appropriate position to indicate which step of hemostasis it describes.

Coagulation -Also known as clotting -Includes intrinsic and extrinsic mechanisms -Includes a vast enzymatic cascade of proteins produced by the liver Platelet Plug Formation -Involves the production of protacyclin -Involves endothelial collagen exposure Vascular Spasm -The first stage in homeostasis

Put the pattern of circulation into the correct order, beginning with the pulmonary circulation.

Correct: 1 Blood leaves the right side of the heart. Correct: 3 Blood enters the pulmonary veins. Correct: 4 Blood enters the left side of the heart. Correct: 5 Blood enters the systemic arteries. Correct: 6 Blood delivers oxygen to the tissues, and then enters systemic veins. Correct: 2 Blood enters the pulmonary arteries and travels to the lungs.

Put the life cycle of an erythrocyte in order, beginning with their formation in red bone marrow.

Correct: 1 Erythrocytes form in red bone marrow. Correct: 4 Hemoglobin is converted to biliverdin. Correct: 3 Erythrocytes are phagocytized in the liver and spleen. Correct: 2 Erythrocytes circulate for 120 days in the bloodstream.

Match the plasma protein with its description.

Correct: 2 Albumin Correct: 1 Globulins Correct: 3 Fibrinogen Correct: 4 Regulatory proteins
