The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.
What is septum primum and septum secundum?
- The septum primum, which divides the right from the left, is a structure inside the primitive atrium.
- In the direction of the endocardial cushions, this septum descends.
- The foramen primum, a hole in this septum, keeps the blood flowing through the heart.
- The foramen secundum develops as the foramen primum shrinks in size.
What is the purpose of septum secundum?
- A muscular flap called the septum secundum plays a significant role in heart growth.
- It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum.
- It is crucial for the foramen ovale to close after birth.

At 16 weeks' gestation, the fundus is midway between the symphysis pubis and
umbilicus. At 36 weeks' gestation, the fundus can be palpated just below the
ensiform cartilage.
