HEART Flashcards
the heart, blood vessels and blood together,
CARDIOVASCULAR SYSTEM
a muscular organ that is essential for life because it pumps blood through body.
HEART
Where is the heart located?
thoracic cavity between the two pleural cavities that surrounds the lungs.
The heart is surrounded by it’s own cavity, the?
pericardial cavity
The right side of the heart pumps blood to the lungs and back to the left side of the heart through vessels.
pulmonary circulation
The left side of the heart pumps blood to all other tissues of the body and back to the right side of the heart through vessels.
Systemic circulation-
blunt, rounded point of the heart.
Apex
larger, flat part at the opposite end of the heart.
Base
heart, trachea, esophagus and associated structures form a midline.
Mediastinum
emergency procedure that maintains blood flow in the body if a person’s heart stops.
Cardiopulmonary resuscitation (CPR)
surrounds the heart and anchors it within the mediastinum.
Pericardium (pericardial sac)
2 LAYERS OF THE PERICADIUM
Fibrous and Serous pericardium
outer layer of the pericardium.
Composed of tough, fibrous connective tissue.
Fibrous pericardium
inner layer; Consists of flat epithelial cells with a thin layer of connective tissue.
Serous pericardium
2 parts of the serous pericardium
parietal and visceral pericardium
lines the fibrous pericardium.
Parietal pericardium
covers the heart surface.
Visceral pericardium (epicardium)
located between the visceral and parietal pericardia, filled with pericardial fluid.
Pericardial Cavity
- produced by serous pericardium.
- Helps reduce friction as the heart moves within the pericardium.
Pericardial fluid
An inflammation of the serious pericardium.
Pericarditis
a potentially fatal condition in which fluid or blood accumulates in the pericardial cavity and compresses the heart from the outside.
Cardia tamponade
Functions as reservoirs. Where blood returning from veins collects before it enters the ventricles
Right and Left ATRIA
Receives blood from the superior vena cava, inferior vena cava and coronary sinus.
Right Atrium
drain blood from the most of the body,
Superior and Inferior Vena Cava
