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.

Answer:
The correct answer is - 38.15 gm of NaCl.
Explanation:
Write the balanced equation for this reaction of sodium (Na) and chlorine (Cl₂) to produce sodium chloride (NaCl):
2Na + Cl₂ —> 2NaCl
the mass of Na and the mass of NaCl :
Molar mass of Na = 23 g/mol
In the balanced equation = 2 × 23 = 46 g
Molar mass of NaCl = 23 + 35.5
= 58.5 g/mol
similarly in balanced equation = 2 × 58.5 = 117 g
From the balanced equation above,
46 g of Na reacted to produce 117 g of NaCl.
By converting it to 15 grams of Na.
Therefore,15 g of Na will react to produce = (15 × 117)/46 = 38.15 g of NaCl.
Thus, 38.15 g of Na
Answer:
The difference in air density between the land and sea cause y the sun's heating.
Explanation:
The sea breeze circulation is composed of two opposing flows; one at the surface (called the sea breeze) and one aloft (which is a return flow)
It’s not different bc we still live in it and it’s still a servicing thing
