Summary Introduction
Introduction:
Blood is the body fluid that contains blood cells suspended in blood plasma. It transports nutrients, gases, and salts within the body. It also maintains body homeostasis with the external environment. Types of blood cells are erythrocytes, leukocytes, and blood platelets.

- Select the incorrect statement about hemostasis: O A. In the process of coagulation, the intrinsic and extrinsic pathways lead to the activation of plasmin, which serves to activate fibrinogen, producing fibrin fibrils. O B. In platelet plug formation, platelets begin sticking to the collagen exposed when the vessel wall was damaged. The platelets forming the plug attract more platelets to the area in a positive feedback loop. OC. Coagulation is the process of platelet plug stabilization through the formation of fibrin fibrils. O D. Vascular spasm is the initial phase of hemostasis It begins when a blood vessel is severed, resulting in a reflexive narrowing of the vessel through smooth muscle contraction.arrow_forwardWhich of the following statements about erythropoietin is true?a.

- Hemostasis is a quick and localized sequence (cascade) of events that helps to prevent a hemorrhage from occurring when a blood vessel is damaged. Hemostasis involves – amongst other things – the formation of a platelet plug. Describe the three steps involved in the formation of a platelet plug. What complication may arise if a platelet plug (thrombus) were to detach and travel through the circulatory system? How does Aspirin help prevent a thrombus from occurring?arrow_forwardThe term "hematopoiesis" refers to: Select one: a. the mechanisms that prevent blood loss O b. the process of blood cell formation O c. the rupture of red blood cells O d. a disease in which there is insufficient blood cell productionarrow_forward
