Document Summary
In center of chest but assymetrical: apex points down to left. The top of the heart is called the base: this is where all the vessels sit. Sits within the paricardium sac (anchored in place at base and to diaphram: the sac is filled with fluid which decreases friction from the heart rubbing against walls when its twists when it contracts. Contains high pressure blood (has to last for the whole circuit) therefore it has very thick walls. Gets blood from the left ventricle, sends it to the rest of the body. Brings blood to the lungs from the right side of the heart. Collects blood and brings it to right side of the heart. Superior collects blood from all working tissues above the diaphram. Inferior collects blood from all working tissues below the diaphram. Come from branches from the lobes of the lungs. Brings blood from lungs to the left side of the heart.
