Step 1: Understanding the function of bile.
Bile is a digestive fluid that helps in the emulsification of fats — i.e., breaking down large fat globules into smaller ones, making them easier to digest by enzymes like lipase.
Step 2: Site of synthesis.
Bile is synthesized (produced) by specialized liver cells called hepatocytes. These cells continuously secrete bile, which then passes through small bile ducts in the liver.
Step 3: Storage and secretion.
After being produced in the liver, bile is stored and concentrated in the gall bladder. During digestion, especially after eating fatty food, it is released into the small intestine (duodenum) through the bile duct.
Step 4: Function summary.
Bile contains bile salts, pigments (bilirubin, biliverdin), and cholesterol. It does not contain any digestive enzyme but helps in fat digestion and absorption by emulsifying fats.

Find the unknown frequency if 24 is the median of the following frequency distribution:
\[\begin{array}{|c|c|c|c|c|c|} \hline \text{Class-interval} & 0-10 & 10-20 & 20-30 & 30-40 & 40-50 \\ \hline \text{Frequency} & 5 & 25 & 25 & \text{$p$} & 7 \\ \hline \end{array}\]
Two concentric circles are of radii $8\ \text{cm}$ and $5\ \text{cm}$. Find the length of the chord of the larger circle which touches (is tangent to) the smaller circle.
