| Term | Definition |
|---|---|
| lymphatic vessels | fight infections and pick up debris |
| lymph nodes | where virus/ bacteria is broken down |
| pulmonary circulation | blood moves from right side of heart to lungs |
| systemic circulation | blood moves from left side of heart to body |
| apex | tip of heart where blood vessels meet |
| Ateries | carry oxygenated blood, nutrients, and hormones |
| veins | carry deoxygenated blood, and waste to heart |
| capillaries | smallest blood vessels. connect arteries to veins. where gas exchange happens |
| septum | separates right of heart from left of heart |
| left of heart | has oxygenated blood |
| right of heart | has deoxygenated blood |
| atriums | have less muscle mass. smaller than ventricles |
| ventricles | more muscle mass than atriums |
| one way valves | separate atriums from ventricles |
| tricuspid valve | valve on right of heart |
| mitral valve | valve on left of heart |
| cholesterol | can form plaque that might block arteries and kill the tissue |
| venacava | largest vein in body. before right atrium |
| right atrium | after venacava, before tricuspid valve |
| tricuspid valve | after right atrium, before right ventricle |
| right ventricle | after tricuspid valve, before pulmonary artery |
| pulmonary artery | after right ventricle, before lung |
| lung | after pulmonary artery, before alveoli |
| alveoli | look like grapes. gas exchange. oxygenate blood. after lung, before pulmonary vein |
| pulmonary vein | only vein that carries oxygenated blood. after alveoli, before left atrium |
| left atrium | after pulmonary vein, before mitral valve |
| mitral valve | after left atrium, before left ventricle |
| left ventricle | largest chamber in the heart. after mitral valve, before aorta |
| aorta | largest vessel. after left ventricle, before arteries |
| arteries | after aorta, before arterioles |
| arterioles | after arteries, before capilaries |
| capillaries | gas exchange. deoxygenates blood. after arterioles, before venules |
| venules | smallest veins. after capillaries, before veins |
| veins | after venules, before going back to venacava |
| lymphatic vessels | fight infections and pick up debris |
| lymph nodes | where virus/ bacteria is broken down |
| pilminary circulation | blood moves from right side of heart to lungs |
| systemic circulation | blood moves from left side of heart to body |
| apex | tip of heart where blood vessels meet |
| Ateries | carry oxygenated blood, nutrients, and hormones |
| veins | carry deoxygenated blood, and waste to heart |
| capillaries | smallest blood vessels. connect arteries to veins. where gas exchange happens |
| septum | separates right of heart from left of heart |
| left of heart | left of heart |
| right of heart | has deoxygenated blood |
