Cardiac myocytes are also known as…

Dark lines parallel to and hold cardiac cells tightly together
Heart lies in which body cavity
Mediastinum
Heart is surrounded by the?
Pericardium
Pericardium is broken up into 2 layers…the first being an outer layer called the?
Fibrous paracardium
Pericardium is broken up into 2 layers…the second being an inner layer called the?
Serous paracardium
The serous pericardium is broken up into its own two layers, the outer layer being the?
Parietal pericardium
The serous pericardium is broken up into its own two layers the inner layer being?
Visceral pericardium, aka “epicardium”
Pericardial cavity
Is a space between the visceral and parietal pericardium which contains serious fluid. The serous fluid helps the heart beat without friction
The heart is made of 3 layers the outermost being?
Epicardium: made of epithelial and loose connective tissue
The heart is made of 3 layers the middle layer being?
Myocardium: the muscle of the heart itself. Is made up of cardiac muscle and fibrous skeleton
The heart is made of 3 layers the innermost being?
Endocardium: made up of endothelium
The heart has 4 chambers used to help recieve and oxygenate blood the first being the?
Right atrium:
- located right superior
- recieves deoxygenated blood
- recieves blood from superior and inferior vena cava, and coronary sinus which all together are known as the systemic circuit
The heart has 4 chambers used to help recieve and oxygenate blood the second being the?
Right ventricle:
- inferior right chamber
- blood travels from the pulmonary trunk, to the left and right pulmony arteries which then delivers blood to the lungs. Collectively this is known as the pulmonary circuit
