    The circulatory system is composed of vessels that take blood from the heart, thin-walled capillaries where exchange occurs, and vessels that return blood to the heart. Blood is pumped by the heart simultaneously into two ways the pulmonary and systemic circuits. The pulmonary system takes blood through the lungs where gas exchange occurs and the systemic system transports blood to all parts of the body where exchange with tissue fluid takes place. In practical terms, we can think of the systemic circuit as a means to conduct blood to and away from the capillaries, because only here does exchange with tissue fluid take place. Nutrient molecules leave the capillaries to be taken up by the cells, and waste molecules given off by the cells are received by the capillaries to be transported away. Capillaries abound in all parts of the body, and no cell is more than a few micrometers from a capillary. Blood is composed of two parts: formed elements and plasma. All of the formed elements contribute to homeostasis, as outlined in table 1. Oxygen is utilized during cellular respiration, a process that…

    The heart is a complex organ that we need in order to pump blood to our body. The cardiac cycle and blood pressure (BP) are two things that greatly affect how our body can function. Both are a part of the circulatory system. There are many diseases that can affect the cardiac cycle and the BP. These diseases can affect our circulatory system, lungs, and our heart’s ability to function properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The…

    The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

    The cardiovascular, lymphatic, and circulatory system and effects of massage Megan Bernard Carrington College As the respiratory, lymphatic, and circulatory systems have been explored through the years, we have learned of the importance of their functions in the body. In more recent years there have been studies to try and understand the effects that massage may have on these different systems and the known pathologies that plague them. We will be looking at some of these studies…
