objects

• -Observation and analysis of the main structures of the cows kidney.
• - Analyze the main parts of the kidney: neprhons, columns kidney, renal delvis, cartical zone and malpighian tubes.
• -To determine the cartical zone from the medular one.

Introduction

• the excretory system is one of those responsible for disposal of waste from cell metabolism. the most important organs in this system are the kidneys, as responsible for the removal and disposal of almost all wastes that are toxic to the body, in addition to mediating the regulation of water balance.

Process

• 1.place the kidney in a container.
• 2.with a scalpel cut the kidney into two parts and observe its internal and external structure.
• 3.identifies parts of the kidney.
• 4.we indicated the names of the parts of the kidney.

Materials

• -kidney
• -scalpel
• -container
• -scissors
• -dissecting forceps

questions?

• 1 What are the external and internal features of the kidney, explain them deeply?
• internal parts
• -renal medulla:is the inner region of the parenchyma of the kidney, the medulla consists of multiple pyramid al tissue masses, called the renal pyramids.
• -renal cortex:a layer of tissue that is also covered by renal fascial and the renal capsule. the renal cortex is granular tissue due to the presence of nephrons.
• -renal pelvis:contains the helium. the hilum is the concave part of the beans-shape where blood vessels and nerves enter and exit the kindey.

Question

• external parts: ºthe kidneys are a pair of bean shaped, brown organs about the size of your fist. they are the covered by the renal capsule, which is tough capsule capsule of fibrous connective tissue. adhering to the surface of each kidney are two layers of fat to help cushion them. the asymmetry within the abdominal cavity caused by the liver typically results in the right kidney being slightly lower than left, and left kidney being located slightly more medial than the right . the right kidney sits just below the diaphragm and posterior to the liver, the left below the diaphragm and posterior to the spleen.

Question?

• 2.What are the illness that affect the urinary system
• -nephrosis: a non inflamantory disease of the kidneys.
• -nephrolith:a kidney stone.
• -urethritis: inflammation of the urethra, the final pathway for urine in both sexes and the common pathway for urine and semen in the male.
• -nocturia: frequently getting up and urinating during the night.
• -enuresis:involuntary release of urine,most often in reference to bedwetting
• -cystitis. inflammation of the blander often from a infection.
• -renal failure: which it is the inability of the kidney to filter urine.

Question?

• 3. How must we take care of our urinary system?
• step1:Drink plenty of water. It is generally recommend to drink at least eight 8-oz. Glasses of water per day. It is ok to drink other fluids, such as juices. However water is vital to keeping the kidneys flushed.
• step2:use the bathroom when the urge arises.
• step3:Wipe front to back to prevent a urinary tract infection in female patients. Because the female urethra is an opening to the urinary tract, if bacteria is introduced into the tract it can cause an infection.

Question?

• Step 4:Eat a healthy diet including fruits, vegetables, protein and whole grains. Eating a diet high in fat can place stress on the kidneys when attempting to extract urea during processing.

Conclusion

• After realized this laboratory , we can conclude that the kidneys fulfill a very important function in our body since they allow the good functioning of our organism because they are that filter the blood and eliminate the waste like uric, acid uric, urea through the urina.
