📖 Comprehensive Study Notes Summary
### Mammalian Circulatory System
#### The Double Circulation
1. **Pulmonary Circulation**: Deoxygenated blood pumped from Right Ventricle -> Pulmonary Artery -> Lungs (oxygenated) -> Pulmonary Veins -> Left Atrium.
2. **Systemic Circulation**: Oxygenated blood from Left Ventricle -> Aorta -> Body tissues -> Vena Cava -> Right Atrium.
#### Blood Groups (ABO System)
- **Group A**: A antigen on RBCs, anti-B antibody in plasma.
- **Group B**: B antigen on RBCs, anti-A antibody in plasma.
- **Group AB**: Both A and B antigens, no antibodies (Universal Recipient).
- **Group O**: No antigens, both anti-A and anti-B antibodies (Universal Donor).
