Study Notes
Anatomical Planes and Sections
- Frontal (coronal) section: separates the body into front and back portions
- Sagittal section: separates the body into right and left portions; midsagittal section creates equal right and left halves
- Transverse section: separates the body into upper and lower portions
- Cross-section: a plane perpendicular to the long axis of an organ; example: a cross-section of the small intestine is a circle with the cavity in the center
- Longitudinal section: a plane along the long axis of an organ
Circulatory System
- Function: transports oxygen and nutrients to tissues and removes waste products
- Heart: primary function is to pump blood through arteries, capillaries, and veins
Heart Structure
- Located in the thoracic cavity between the lungs (mediastinum)
- Base: uppermost, behind the sternum; great vessels enter or leave here
- Apex: tip of the heart, points downward, just above the diaphragm to the left of the midline
Pericardial Membranes
- Three layers: fibrous pericardium, serous pericardium, and epicardium
- Fibrous pericardium: outermost, loose-fitting sac of strong fibrous connective tissue
- Serous pericardium: folded membrane with parietal and visceral layers; contains serous fluid to prevent friction
- Epicardium (visceral pericardium): layer on the surface of the heart muscle
Chambers and Valves of the Heart
- Walls of the four chambers: made of cardiac muscle (myocardium)
- Lined with endocardium: simple squamous epithelium that also covers valves and continues into vessels as endothelium
- Endocardium: smooth surface prevents abnormal blood clotting
