In cognitive therapy, clients learn to: 1  Distinguish between thoughts and feelings. 2  Become aware of the ways in which thoughts can influence feelings in ways that sometimes are not helpful. 3  Learn about thoughts that seem to occur automatically, without even realizing how they may affect emotions.
The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle.he essential components of the human cardiovascular system are the heart, blood and blood vessels. It includes the pulmonary circulation, a loop through the lungs where blood is oxygenated; and the systemic circulation, a loop through the rest of the body to provide oxygenated blood.
The heart pumps oxygenated blood around the body by the arteries which then enter tissues through tiny capillaries. Once the oxygen has diffused across into the cells, carbon dioxide then bonds to the red blood cells instead. Now the blood has very little oxygen and lots of carbon dioxide. It is transported back to the heart by veins (of which the biggest is the vena cava) to be pumped up to the lungs. This is where it gets a bit strange. Previously, any vessel carrying oxygenated blood was an artery whilst any vessel carrying deoxygenated blood was a vein. With the lungs, it is reversed.
