1. Compare the anatomy of a vein, artery, and capillary . Arteries transport blood away from the heart. Veins return blood to your heart. Capillaries are the smallest blood vessels, they connect arteries and veins. 2016 (p. 330). Fundamentals of Anatomy and Physiology .

"A cardiac cycle or complete heartbeat, there-fore, consists of the systole and diastole of both atria and the systole and diastole of both ventricles. The pressure developed in a heart chamber is related to the chambersize and the volume of blood it contains. " A myocardial infarct rapidly impairs cardiac contractile function and instigates maladaptive remodeling leading to heart failure 2016 (p. 331). Fundamentals of Anatomy and Physiology .

Blood typing is so important because if you would ever donate blood or need to receive blood it is a lot easier to know your blood type then not know. 2016 (p. ). Fundamentals of Anatomy and Physiology . Retrieved from https://platform.virdocs.com/r/s/0/doc/732417/sp/277750997/mi/806714537?cfi=%2F4%2F4 4. Explain the different types of arrhythmia and why arrhythmias are dangerous? The most dangerous arrhythmia is ventricular fibrillation, which is characterized by an uncontrolled, irregular heartbeat. Instead of a single erroneous beat from the ventricles, you could have several impulses that start at the same time from different locations, all telling the heart to beat. 2016 (p. ). Fundamentals of Anatomy and Physiology . Retrieved from https://platform.virdocs.com/r/s/0/doc/732417/sp/277750997/mi/806714537?cfi=%2F4%2F4 5. Describe why breathing in excessive carbon monoxide is toxic to our bodies. Carbon monoxide poisoning occurs when there is an accumulation of carbon monoxide in the blood. When there is an excess of carbon monoxide in the air, the body replaces the oxygen in red blood cells with carbon monoxide. This can result in severe tissue damage or even death. 2016 (p.355 ). Fundamentals of Anatomy and Physiology . Retrieved from https://platform.virdocs.com/r/s/0/doc/732417/sp/277750997/mi/806714537?cfi=%2F4%2F4 6. Explain why sedentary lifestyles put a person at risk for increased blood clotting. Your muscles will not contract if you sit for an extended period of time. When this happens,

blood clots can form and block your deep veins. Working a sedentary job that requires sitting for long periods of time is another risk factor for DVT formation. 2016 (p.371 ). Fundamentals of Anatomy and Physiology . Retrieved from https://platform.virdocs.com/r/s/0/doc/732417/sp/277750997/mi/806714537?cfi=%2F4%2F4
