L2: Circulatory System (HUMAN HISTOLOGY LEC)

Brings blood from the heart to the lungs and then back to the heart.

• Pulmonary circulation
• Systemic circulation
• Cardiovascular circulation
• Lymph vascular system

Brings blood from the heart to all the other tissues and organs of the body, and then back to the heart.

• Pulmonary circulation
• Systemic circulation
• Cardiovascular circulation
• Lymph vascular system

The four chambers of the heart consists of:

• 2 Inferior Vena Cava and 2 Superior Vena Cava
• 2 Coronary Vessels and 2 Pulmonary Arteries
• 2 Atrium and 2 Ventricles

The connective tissue that covers the heart.

• Endocardium
• Pericardium
• Myocardium
• Epicardium

The three great vessels are composed of the following, except:

• Inferior Vena Cava
• Superior Vena Cava
• Aorta
• Coronary Vessels

The two layers of the pericardium are:

• Fibrous pericardium and Serous pericardium
• Parietal pericardium and Visceral pericardium
• Pulmonary pericardium and Systemic pericardium
• Myocardium and Epicardium

Loose connective tissue covered by mesothelium

• Visceral pericardium
• Mesothelial pericardium
• Pericardial cavity
• Parietal pericardium

This is synonymous with epicardium

• Parietal pericardium
• Mesothelial pericardium
• Visceral pericardium
• Pericardial cavity

Reduces friction between the parietal and visceral pericardium during contraction.

• Pericardial fluid
• Serous fluid
• Fibrous pericardium
• Serous pericardium

These are modified cardiac muscle fibers; Non-contractile and pale staining.

• Gap junctions
• Desmosomes
• Purkinje fibers
• Fascia adherens
