Transportation of vital nutrients, such as oxygen, to the cells and removal and transport of cellular wastes, such as carbon dioxide.What organs make up the cardiovascular system? Heart and the Blood VesselsDiscuss how the parasympathetic and the sympathetic nervous systems influence the heart? Sympathetic Nervous System increases heart rate during fight or flight responses or from stress. The parasympathetic nervous system decrease heart rate back to its normal beat.
HEART ANATOMY: 1. Located in the __Bony Thorax___, 2/3 of it is on the left side of midline, 1/3 is on the right. 2. Size and shape is similar to a __Human Fist__ 3. Weighs approx. 11 oz. and pumps __Blood___ 4. Where is the heart located? Medial to the lungs and anterior to the spine inside of the bony thorax.5. What are the three main layers of the heart? Describe them.Epicardium – also called the visceral pericardium, outermost layer of the heartMyocardium – cardiac muscle layer of the heart, thickest layerEndocaridum – innermost layer of endothelium4 CHAMBERS: Right Atrium - receiving chamber (from _Vena Cavae, both superior and inferior_) Left Atrium - receiving chamber (from __left and right pulmonary veins__) Right Ventricle - discharging chamber (to _pulmonary trunk and pulmonary arteries__) Left Ventricle - discharging chamber (to __aorta_) _Septum_ = the wall between chambers _Myocardium_ = walls of twisted and whorled cardiac muscle, the layer that actually contracts_Endocardium__ = smooth lining of heart chambers (inflammation of this is called endocarditis) _Pericardium_ = covering sac containing lubricating fluid 2 layers of Heart’s Protective covering: 1. _Visceral__ pericardium = inner layer (also called epicardium) 2. _Parietal__ pericardium = outer layer HEART VALVES: 1. ____Tricuspid____ Valve = between right atrium and ventricle 2. ____
