The medulla is the inner region of the parenchyma of the kidney. The medulla consists of multiple pyramidal tissue masses, called renal pyramids.
The kidney's parenchyma's interior section is called the medulla.
The renal pyramids, which are triangle-shaped structures with a dense network of nephrons within them, are a collection of several pyramidal tissue masses that make up the medulla.
The Bowman's capsule, which is shaped like a cup and is located in the cortex of the kidney, is at one end of each nephron. The glomerulus, a group of capillaries that conducts blood from the renal arteries into the nephron where plasma is filtered via the capsule, is encircled by it.
The filtered fluid exits the capsule and travels via the collecting ducts and distal convoluted tubule before exiting the body through the ureter. It then travels down the proximal convoluted tubule to the loop of Henle. The complicated management of water and ion concentrations in the body is made possible by the numerous components of the nephrons, each of which is selectively permeable to distinct molecules.

Sugar and salt are examples of soluble substances. Substances that do not dissolve in water are called insoluble. Sand and flour are examples of insoluble substances.
Chalk is insoluble - it does not dissolve in water.
Answer:
One of the interesting aspects of organic chemistry is that it is three-dimensional. A molecule can have a shape in space that may contribute to its properties. Molecules can differ in the way the atoms are arranged - the same combination of atoms can be assembled in more than one way. These compounds are known as isomers. Isomers are molecules with the same molecular formulas, but different arrangements of atoms. There are several different types of isomers which will be described and a flowchart (see figure below) can help you determine which type of
