Explain the process of preventing blood loss.  The blood leak to the other tissue or is lost from the body when a blood vessel is damaged. The body can produce another blood when the body resists a small amount of blood loss. It can lead to death if a large amount of blood loss. But these can be preventing or minimized when blood loss and damaged the blood vessels. The vascular spasm, platelet plug formation, and blood clotting or coagulation. This process is called hemostasis. And platelets are the key players for this. The vascular spasm is happening when a vessel is ruptured. This involves the contraction of the vascular smooth muscle proximal to the injury site. The thromboxane A2 a regulatory substance is produced by platelets that promote vasoconstriction. This contraction restricts the supply of blood to the injured site, thereby limiting the loss of blood. Platelets generate a platelet plug that forms nearly immediately after the damages of the blood vessels. When the platelets have been trapped, it releases ADP and thromboxane a2. Then, when platelets accumulate, they eventually produce chemicals through their granules to the plasma that further leads to hemostasis. Adenosine diphosphate (ADP), serotonin, and prostaglandins and phospholipids are the substance that released by the platelets. This can help to prevent blood loss from the injury site. When severely blood vessels lose blood coagulation or blood clotting can happen. The fibrinogen is turned to fibrin, which generates a chain that holds more platelets and erythrocytes, releasing clots. This includes the formation of prothrombin's that arises in two ways the extrinsic and intrinsic pathways. An extrinsic is typically caused by trauma and the intrinsic pathway starts in the bloodstream and is caused by internal disruption to the wall of the vessel. Explain the pathophysiology of anemia (in general).  When the levels of hemoglobin are low it refers to condition of anemia. But these depending on the type of anemia affecting to person. This can be also caused by the reduction of hemoglobin. Hemoglobin is responsible for providing oxygen to the muscles, this condition will make you feel exhausted and sluggish. Blood loss, decreased development of red blood cells, and increased destruction of red blood cells are some of the causes of this condition. You may not feel or experience anemia if it is mild. Fatigue or tiredness, weakness, pale appearance to the skin, dizziness, rapid heartbeat known as tachycardia, shortness of breath, and jaundice are the symptoms of anemia that a person feels if it worsens. This condition is easy to diagnose by a complete blood count (CBC) test. Also, it is treatable depending on the types of anemia by taking supplements like iron or vitamin B12, blood transfusions, and many more.
