Chapter 16 Altered Perfusion Flashcards
What is perfusion
the process of forcing blood or other fluid to flow through a vessel to provide oxygen & other nutrients.
What is, the ability to breathe in & transport oxygen across the capillaries for effective distribution of oxygen to the tissues, called?
Adequate ventilation & diffusion
required for the uptake of oxygen from inspired air
Intact pulmonary circulation
optimal, surface tension, alveoli is lowest, lungs easily inflated
Ventilation
optimal, blood pressure, lower lobes, max blood flow
Perfusion
circulation through lungs,transfer oxygen from atmosphere into body
Pulmonary Circulation
circulation, blood flow to heart, pumps oxygenated blood to body
Cardiac Circulation
circulation, oxygen and nutrients to other body tissues
Systemic Circulation
what transports oxygenated and nutrient-rich blood to tissues?
Arteries
Ventilation —- perfusion is ________ dependent.
gravity
outer covering of heart, regulate BP & HR, 1st line of defense against infection and inflammation
Pericardium
provide cushion, lubricates, minimize friction as heart beats.
Pericardial Fluid
thick muscular layer of heart, left ventricle thicker due to working harder, undergoes hypertrophy if workload increases
Myocardium
inner lining of heart, continuous layer of endothelium, joins arteries & veins to heart, forms closes circulatory system
Endocardium
refers to 1 contraction and 1 relaxation phase
Cardiac Cycle
