Document Summary
Interaction: how systems interact and work together: sum of the whole is greater than the sum of its parts. What structure, what it is, how it works. How the different things work together to form a whole and work together. Circulatory system: made up of the heart, blood vessels and blood. Transport: nutrients, gasses, metabolic wastes, and hormones. Protection: clotting, immune system (connected to the circulatory system): against infection/disease. Cardiovascular system: made of the heart, arteries, veins and capillaries. Two separate divisions of the cardiovascular system: pulmonary & systemic circuits. Pulmonary circuit: right side of the heart. Systemic circuit: left side of the heart. Outer, tough, fibrous layer of connective tissue. Inner thin smooth moist serous membrane layer. Serous membrane in parietal layers inside of the body cavities (inside e. g. , thoracic cavity): membrane produces a lubricating fluid: pericardial cavity. Filled with pericardial fluid: visceral pericardium (or epicardium of heart wall) Inner, thin, smooth, moist serous membrane layer.
