How to draw LS of kidney


The LS of kidney shows outer dark zone called the cortex and inner pale red zone called medulla which forms the main mass of the kidney.The medulla is made of number of pyramidal structures containing renal tubules or Nephrons projecting into the cavity towards the inner region of kidney called pelvis.This
is the region where renal artery and renal vein enter the kidney. Free end of pelvis shows cup like depressions called calyces. Renal pyramids of medulla project into these calyces.Now, lets`s start drawing the diagram. Here we go.
 

1.Draw a bean shape as shown in figure

2.Erase the depression and make it double lined.
 
3Draw the Pelvis and ureter coming out of the opening.

4.Mark about seven radiating lines along  the inner  curvature.




















5.Draw the renal pyramids as shown along the inner curvature of kidney.

6.Draw Calyces connecting the renal pyramids as shown in figure.



7.Mark several lines that represent Nephrons in each renal pyramid and draw 
    renal vein and real artery  as shown.

8.Label the parts neatly as shown in figure below.

How to draw Nephron Each kidney is made of about one million single units called nephrons. These are the structural functional units of the kidney and concerned with separating urine from the blood. Each nephron is made of two main parts called malpighian body and covoluted tubule.Malphigian body is double layered cup also called bowman`s capsule. The inner cup consists network of capillaries called Glomerulus.                                    Now let`s start the diagram. 1.Draw a egg shape and  make a folded curve as shown in the figure and     attach it to a vertical line. 2. Draw double line along the curve and draw Glomerulus as shown in the      bowman`s capsule. 3. Draw the capillary network as shown in the figure. You may need some patience to represent the intricate network. You can make it simple by drawing the whole capillaries with single thick line, using blunt pencil tip.

How to draw skin LS Our  skin  is the sense organ for touch. It contains cutaneous receptors for touch. The skin consists of two main layers called epidermis and dermis. Epidermis is the layer for protection. It has outer stratum corneum or cornified layer containing dead cells, middle granular layer containing living cells and inner malpighian layer containing the cells dividing constantly.  Dermis lies below the epidermis. It is made up of elastic connective tissue. It contains sweat glands, sebaceous glands, hair follicles, blood vessels and fat. Here we start the diagram. 1.Draw a cuboid shape as shown.  2.Draw the epidermis and endodermis as shown.  3.Draw hair follicles and other details of the skin as shown.  4. Label the parts as shown.
