Document Summary
Top killer and reason for hospitalizaion in the u. s. and the developed world. Atherosclerosis - blockage of blood vessels: can lead to heart atacks, stroke, etc, hardening of the arteries, buildup of cholesterol plaque. Heart failure: reduced ability of heart to pump blood (oxygen, etc. ) Inadequate blood low (oxygen, etc. ) to part of the brain. Inadequate blood low (oxygen, etc. ) to part of the heart. Not blood (blood circulates in blood vessels of the cardiovascular system) Lymph: forms from luid between cells (intersiial luid, travels in vessels from issue to the cardiovascular system, helps protect against infecions (wbcs in lymph nodes that the lymph lows through) Inhalaion is acive (muscle contract) major respiratory muscles (diaphragm and rib muscles) contract. Lung volumes and venilaion: exchange of air within the lungs, only part of air within the lungs is exchanges with each breath. Air within alveoli in the lungs has less o2 and more co2 than air in the atmosphere.
