First aid is care given to someone before a paramedic arrives so for example.. If you and your friend are out on the trails on atvs and your friend wrecks his/her dirt bike and you are miles from the nearest help what would you do? without first aid your friend could die he/ she has a large deep gash in their thigh. It is bleeding bad and applying pressure isn't helping stop it. You remember something from first aid class that may help but your friend could lose their leg and is very scared. so you would try to calm him/her down reassure them and,then you apply a tourniquet to stop the bleeding. now you take your friend to the nearest help. You just saved your friends life but, if you didn't know first aid he/she could've died by the time a paramedic made it to where you were. That is why is important to know. that is what we were taught in my class it worked we all passed and knew how to apply first aid. hope this helped. :)
The outermost layer of bone is called connective tissue
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.
Acquired traits include things such as calluses on fingers, larger muscle size from exercise or from avoiding predators.
