between heart and lungs
pulmonary arteries-pumps blood to lungs
pulmonary veins-pumps blood to body |
|
|
Term
|
Definition
between heart and tissues
heart pumps blood via aorta
heart recieves blood via superior and inferior vena cavae |

Term
|
Definition
lub-closing of aortic valve (systole)
dub-closing of semilunar valve (diastole) |
|
|
Term
|
Definition
| caused by calcifying of mitral valve and impairs flow between right atrium and ventricle, may result in pulmonary hypertension |
|
|
Term
|
Definition
| when valves do not close properly can be caused by damaged papillary muscles |
|
|
Term
|
Definition
| caused by holes in interventricular or interarterial septum...blood crosses sides |
|
|
Term
|
Definition
systole-contraction of heart muscles
diastole-relaxation of heart muscles |
|
|
Term
| cardiac muscles are interconnected... |

|
|
Term
| epinephrine and norepinephrin role in heart |
|
Definition
| produces more cAMP, which keeps NA+ channels open, which speeds up heart rate |

Definition
have 3 tunics
1. tunica intima
2. media
3. externa |
|
|
Term
|
Definition
| Tunica Intima- composed of simple squamous endothelium on basement membrane with connective tissue |
|
|
Term
|
Definition
| Middle layer, composed of smooth muscle tissue |
|
|
Term
|
Definition
| outer layer composed of connective tissue |
|
|
Term
|
Definition
| single layer simple squamous epithelium, where gases and nutrients exchanged between tissues, blood flow regulated by vasoconstriction, and vasodilation |
|
|
Term
|
Definition
1. continuous capillaries- found in muscle add to blood brain barrier
2. fenestrated capillaries-have pores in vessel walls, found in kidneys, endocrine system, intestines
3. discontinuous-have gaps between cells, found in bone marrow,spleen, liver, allow for passage of proteins |
|
|
Term
|
Definition
| Plaques intrude on the lumen and reduce blood flow |
|
|
Term
|
Definition
characterized by inadequate oxygen due to reduced blood flow
- atherosclerosis is most common cause |
