5. ___________ _________ ________ are the body’s defense system, they all fight infection from bacteria and viruses. 6. When granulocytes find the invader germ they quickly move in for the kill, first attacking the invader and then

eating ______________ them (phagocytosis). platelets 7. ________________ are small pieces of cell material or cytoplasm whose job it is to plug holes in the vessel walls. Animation: How Red Blood Cells Carry Oxygen and Carbon Dioxide

nucleus 1. Erythrocytes lack most of the typical cell structures, they have no _________________, and almost no regenerate organelles This means they cannot __________________, __________________. cannot synthesize new proteins and cannot use the ___________________ oxygen __________________, they are carrying. bioncave 2. Erythrocytes are shaped almost like a donut, with _____________________ surfaces. four polypeptide (protein) chains, each of which is bound to a red pigment 3. Hemoglobin is composed of _________ heme Heme binds ________________ oxygen iron molecule called __________. to a ferrous __________ in its center. Thus, a four molecules of oxygen. molecule of hemoglobin can bind up to _________ reversable 4. Formation of the hemoglobin-oxygen complex, known as oxyhemoglobin is ___________________, depending on oxygen partial pressure. 5. While hemoglobin is responsible for transport of most of the oxygen, it only carries a small portion of

carbon dioxide _____________ ______________. bicarbonate 6. The majority of carbon dioxide is transported in the blood in the form of ______________________ ions. Animation: Video 9 White Blood Cells Types and Functions

Animation: Platelet activation and Factors for Clot Formation 1. In the first step (after vascular spasm) towards clot formation _________________ are recruited to the site of vessel platelets

collages injury by now exposed molecules of the vessel wall such as __________________ and von Willebrand factor. activation 2. The resulting change of shape of the platelet from its resting state into the dendritic form indicates _____________. adenosine 3. The activated platelets in turn release prothrombotic molecules such as ______________ ______________(ADP). aggregation By binding to its receptors ADP induces ________________________. thromboxe 4. _______________________ is another important mediator of platelet activation and aggregation under its influence the platelets cross link with each other.

coagulation cascade and thus the formation 5. The clot grows rapidly, the activated platelets also trigger the __________________ of thrombin. Thrombin in turn stimulates platelet activation even further a continuous (positive) feedback loop.

fibrin 6. Additionally, thrombin induces the formation of ______________ for the mesh stabilizing the clot....
