precautionsfor studying external and internal features of kidney
Answers
Kidneys have a very distinct shape and color. They are bean-shaped and dark-red in color. In fact, they look very similar to red kidney beans.
One side bulges outward (convex) and the other side is indented (concave).
The indented or concave section is known as the hilum. This is where the renal artery, the renal vein and the ureter enter/ exit the kidney.
Each Kidney is enclosed in a semi-transparent membrane called the renal capsule. It is the container or sac in which the other components of the internal anatomy of the kidneys are stored.
The renal capsule is not only a storage container for internal components of the kidneys but it also protects against infections and trauma.
Internal Kidney:-
If a human kidney, is sliced vertically (from top to bottom), the intricate structure of the internal anatomy is revealed. These internal components are responsible for performing the many essential functions of the kidney.
Some of these components can be seen with the naked eye and are known as the gross anatomy. Others are very tiny and can only be observed with a microscope. These are referred to as the microscopic anatomy.
The internal structure of the kidney is divided into two main areas... a light outer area called the renal cortex, and a darker inner area called the renal medulla. Within the medulla there are eight (8) or more cone-shaped sections known as renal pyramids. The renal papilla is located at the smaller end of the cone-shaped renal pyramids. The areas between the pyramids are called renal columns.
Each renal papilla is attached to a cup, or a small tube, called the minor calyx (CAY-lix), which collects urine for removal from the kidney, and eventually from the body. Two or three of these minor calices (plural of minor calyx) merge into what is called a major calyx.
The major calices then converge into a funnel-like cavity called the renal pelvis. The renal pelvis, which is attached to the indented side of the kidney anatomy (hilum), extends into the ureter. The ureter is a long narrow duct (tube) that conveys urine from the kidneys to the urinary bladder.
hope it's help you.
