- What distinguishes angina from a heart attack? Select an answer from the options below Angina is caused by disrupted blood flow to the heart and lungs, whereas a heart attack is caused by a blockage in the heart muscle. Angina is caused by the death of the heart muscle, whereas a heart attack is caused by a disruption to the blood flow into the heart and lungs. Angina is chest pain due to an insufficient blood supply, whereas a heart attack is the death of the heart muscle tissue. A heart attack is the pain caused by the blood supply being briefly interrupted, whereas angina is caused by a longer disruption in blood flow.Hemostasis is a quick and localized sequence (cascade) of events that helps to prevent a hemorrhage from occurring when a blood vessel is damaged.

How does Aspirin help prevent a thrombus from occurring?Use the word bank below to complete the list of structures an erythrocyte would encounter as it returns from the hand, travels through the pulmonary circulation, and returns to the systemic circulation. right atrium left atrium right ventricle left ventricle superior vena cava pulmonary trunk pulmonary vein inferior vena cava aorta mitral valve pulmonary valve tricuspid valve aortic valve RBC approaches the heart through the following vessel: First chamber it enters: right atrium First valve it passes through: tricuspid valve Second chamber it enters: right ventricle Second valve it passes through: pulmonary valve Vessel it leaves heart through: Left and right pulmonary arteries **lungs" Vessels it returns to the heart through: pulmonary vein 3rd chamber it enters: left ventricle Next valve it passes through: aortic valve 4th chamber it enters: left atrium Last valve it passes through: mitral valve Vessel it leaves heart through: Systemic circulation

- Use the word bank below to complete the following statements: Tissue capillary higher lower oxygen carbon dioxide waste nutrients On the arteriole side of a capillary bed, the capillary hydrostatic pressure is than the blood colloidal osmotic pressure. This causes a net movement of liquid into the This liquid contains a lot of gas and which move down a concentration gradient towards local cells that are continually consuming those resources. On the venule side of the capillary bed, the capillary hydrostatic pressure is than the blood colloidal osmotic pressure, resulting in a net movement of liquid into the . After passing over local tissues, the composition of the liquid has changed, and now contains a lot of gas and Only (write a number and a % sign) of fluid returns to the circulatory system. The remaining portion of fluid is collected by the lymphatic system.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.Which of the following sequences shows the correct pathway of blood from body to lungs?
