Study Notes
Pericardial Space
- Located between two layers
- Contains small amounts of clear fluid
Epicardial Fat
- Follows the coronary grooves
Myocardium
- Muscle of the heart
- Similar to skeletal muscle
- Thin layer lining the internal surface of the heart
- Contains Purkinje fibers
Fetal Circulation
- Venous-arterial shunts present
- Foramen ovale: between left and right atria
- Ductus arteriosus: between pulmonary artery and aorta
Vascular System
- Arteries
- Veins
- Lymphatics
Sclerosis
- Hardening of the arterial wall
- Loss of elasticity
- Reduced vascular lumen
Atherosclerosis
- Deposition of cholesterol in the arterial walls
Arteriosclerosis
- Deposition of minerals in the arterial wall
Arteriolosclerosis
- Hypertrophy of the smooth muscle of the arteriole
- Occurs in cases of hypertension
Aneurysms
- Local weakening and dilation of blood vessels wall
Varicose Veins
- Veins become dilated and twisted
Vasculitis
- Inflammation of blood vessels
- Arteritis: inflammation of arteries
- Phlebitis: inflammation of veins
