Episode notes
Cardiovascular System Overview
- The cardiovascular system pumps and transports blood containing oxygen, nutrients, hormones, and waste products.
- Blood moves one-way through heart chambers and vessels to efficiently supply tissues and remove waste.
Heart Anatomy and Location
- The heart is located in the chest, behind the sternum, between the lungs in the mediastinum.
- Its apex points towards the left hip, beating about 100,000 times a day nonstop.
Heart Chambers and Blood Flow
- Blood enters the right atrium deoxygenated, moves through valves to right ventricle, then lungs via pulmonary artery for oxygenation.
- Oxygenated blood returns via pulmonary veins to left atrium, then left ventricle, and pumped out the aorta to the body.
