acts as a lubricant that allows organs to expand & contract without fiction

-Serous and Fibrous Pericardium

Perfectly

What are the two layers of the Serous Pericardium?

-Parietal and Visceral Pericardium

What is Pericardial Effusion?

the buildup of extra fluid in the space around the heart, allowing it to contract and pump

What are the three layers of the Heart?

-Epicardium
-Myocardium
-Endocardium

What are the four heart chambers?

-Right ventricle and atrium -Left ventricle and atrium

Where is the base of the heart?

-The top

Where is the apex of the heart?

- the bottom

Where is the coronary grove of the heart, & what does it seperate?

- crown of heart -atrium and ventricle

What are the two interventricular groove types?

-Subsinousal IV -Paraconal IV

What is the anatomy of the heart?

- 2 ventricles - 2 atriums - 2 auricles

What is the function of the internal structure of the heart?

-to maintain the structure of the organ, & ensure blood flow in one direction

What is Chordae Tendineae?

- heart strings -attach to the valves in the heart to cardiac wall and prevent them from inverting

What are the inflow valves?

- Right atrium and ventricle -Left atrium and ventricle

What are the outflow valves?

- Aortic and Pulmonary valves

What do Arteries do?

-carry blood away from the heart

What do Veins do?

- carry blood to the heart

What is the first step of Blood Flow?

- blood flows from the vena cava to the Right atrium

What is the second step of Blood Flow?

- then through the Right AV valve to the Right ventricle , which transfer through the lungs

What is the third step of Blood Flow?

-through the pulmonary valve to the pulmonary artery

What is the fourth step of Blood Flow?

- Once the lungs amply oxygenate the blood, the blood goes through the pulmonary veins to the left atrium

What is the fifth step of Blood Flow?

-through left atrioventricular valve and into left ventricle

What is the sixth step of Blood Flow?

-After the oxygenated blood passes through the aortic valve, the heart sends it through the aorta to the rest of the body -ascending, aortic arch, descending

What is the six steps in Fetal Blood Flow #1?

-Oxygenated maternal blood enter fetus through umbilical vein -Passes through liver -Enters caudal vena cava -Right atrium -Foramen ovale; opening between right and Left atria -Left Atrium

What is the 11 steps in Fetal Blood Flow #2?

-Oxygenated maternal blood enter fetus through umbilical vein -Passes through liver -Enters caudal vena cava -Right atrium -Right AV Valve -Right Ventricle -Pulmonic Valve -Pulmonary Artery -Ductus Arteriosus -Aorta -Body

What is the Heart sound Lub S1?

-Simultaneous closure of the tricuspid and mitral valves

What is Heart sound Dup S2?

-Simultaneous closure of the Aortic and Pulmonic Valves

What is thick walled and deals with the pulse?

-Arteries

What is thin walled and more superficial?

-Veins

What are the three Heart Vessels?

-Vena Cava -Aorta -Pulmonary Trunk

What are the parts of the Vena Cava?

-cranial(superior) -caudal(inferior)

What are the parts of the Aorta?

-ascending -aortic arch -descending

What are the parts of the Pulmonary Trunk?

-pulmonary vein (oxygenated) - pulmonary artery

What does the Brachiocephalic trunk include?

- blood to the head and right arm (right subclavian)

What is the Left Subclavian?

- left thoracic limb
