Study Notes
Cardiovascular System
- The Superior Vena Cava receives deoxygenated blood from the upper body and delivers it to the right atrium.
Venous System
- The left Brachiocephalic vein is formed by the left subclavian vein and left internal jugular vein, but not the left external jugular vein or left pulmonary vein.
Respiratory Muscles
- Subcostal muscles are accessory respiratory muscles that function to depress the ribs during forced expiration.
Heart Structure
- The aorta originates from the left ventricle.
- The pulmonary trunk originates from the right ventricle.
- The pulmonary veins enter the pericardium to drain into the left atrium.
