What is kidney dissection?
Kidney dissections are conducted to explore the function of a kidney by examining the external and internal structures. The kidney filters out metabolic wastes such as urea and some salts and regulates the water and salt balance in the body.
What is the smooth semitransparent?
Renal Capsule: A smooth semitransparent membrane that adheres tightly to the outer surface of the kidney. 2. Renal Cortex: The region of the kidney just below the capsule. When your kidney is dissected then you should be able to see blue and red specks scattered through the cortex.
How many types of kidney are found in mammals?
In the course of its development, the mammalian kidney goes through three distinct forms: the pronephros, the mesonephros, and the metanephros, ultimately leading to the formation of the mature kidney (Fig. 1).
How many nephrons are in each kidney?
one million
Each kidney contains about one million tiny units called nephrons. Each nephron is made up of a very small filter, called a glomerulus, which is attached to a tubule. As blood passes through the nephron, fluid and waste products are filtered out.
What are the precautions taken by you after dissecting sheep kidney?
Solution : 1) Wash the kidney thorougly with water. 2) Ensure that blood is completely drained from it. 3) Wash your hands with antibacterial lotion after completing the dissection.
What is adipose capsule?
The adipose capsule of kidney (or perinephric fat or perirenal fat) is a structure between the renal fascia and renal capsule, and may be regarded as a part of the latter. A different structure, the pararenal fat, is the adipose tissue superficial to the renal fascia.
What is the structure of mammalian kidney?
Each kidney is comprised of a fibrous outer layer called the renal capsule, a peripheral layer called the cortex, and an inner layer called the medulla. The medulla is arranged in multiple pyramidal structures that together with overlying cortex comprise a renal lobe (red box).
What is the functional unit of the mammalian kidney?
The functional unit of the kidney is the nephron (Figure 1B).
What is animal dissection?
Dissection (from Latin dissecare “to cut to pieces”; also called anatomization) is the dismembering of the body of a deceased animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans.
Why is animal dissection important?
Dissection is also important because it: Helps students learn about the internal structures of animals. Helps students learn how the tissues and organs are interrelated. Gives students an appreciation of the complexity of organisms in a hands-on learning environment.
What precautions would you take while observing the mammalian heart in the laboratory?
Answer: The precautions are: * First we must wash our hands to make it free from dirt. * The person observing or analyzing the heart must wear hand gloves. * The heart should be properly placed in the dissection pan.
What are the 3 regions of the kidney?
The kidney is made up of three different regions internally: the outer cortex, the middle medulla (with the renal pyramids) and the inner-most renal pelvis.

What is dissecting a kidney and why is it important?
Dissecting a kidney allows you to trace the path of wastes and urine through the organ and better understand its function. Mammalian kidneys are part of the urinary system, functioning with the ureter, urinary bladder, and tubular urethra.
How do you dissect a pig kidney external anatomy?
Kidney External Anatomy Place the preserved pig kidney on your dissecting tray. Observe and feel the renal capsule(Figure 1). This structure encapsulates the kidney and is made up of dense, irregular connective tissue. It provides protection and helps maintain the shape of the kidney. Locate the hilus(Figures 1 and 2).
What is the function of the mammalian kidneys?
Mammalian kidneys are part of the urinary system, functioning with the ureter, urinary bladder, and tubular urethra. These organs remove unwanted cellular waste, excess salts, and toxins from the blood.
