In human anatomy, it is the heart that pumps the blood so that it is distributed to throughout the body to provide oxygen and nutrients to the other organs. Hence, it passes different conduits. The largest conduits are the arteries which carries blood away from the heart. Pulmonary arteries, in particular, direct the blood from the heart's right ventricle towards the lungs. The smaller diameter conduits are the veins. Generally, the veins carry deoxygenated or used blood and bring it back to the heart. Exceptions to this is the pulmonary vein and umbilical vein. Finally, the capillaries are very small blood vessels that transport blood between the arteries and the veins.
From the choices, the false statement is letter B. Although this could be true for the pulmonary and umbilical vein, the majority of the veins still transport the blood back to the heart.
According to a 2018 article written by Dr. Mark Stibich, suicide is the 2nd cause accounting for 18% of deaths among people age 15-24.
According to the CDC's 2007 statistics, homicide was the 2nd leading aide of death among people age 15-24.
According to the National Institute of Mental Health 2017 statistics, suicide was the second leading cause of death among individuals between the ages of 15 and 34.
According to the Population Reference Bureau (June 2016), suicides becsme the second cause of death among teenagers in the United States, surpassing homicide deaths.
I would say suicide is the answer, but it will depend on what year's statistics your class reference material is using.
Hope this helps! :)
