what is the microscopic structure of the kidney

What is the gross structure of the kidney?

Structure: The kidneys have been bean-shaped appearance. The outer edge of the kidney is convex and the inner concave. In the concave side there is a depression in the middle point which is called as ‘hilum’ or ‘hilus’. Here the blood vessels of the kidney i.e. Renal artery enters and Renal vein comes out of the kidney.

What is the structure and function of the kidney?

The kidneys, illustrated in Figure 1, are a pair of bean-shaped structures that are located just below and posterior to the liver in the peritoneal cavity. The adrenal glands sit on top of each kidney and are also called the suprarenal glands. Kidneys filter blood and purify it.

What are the microscopic filtering units of the kideny?

Microscopic Structures of the Kidneys - Nephrons. Nephrons are functional units located in the kidneys responsible for forming urine. Nephrons are complexes of a few components: a filtration unit, the renal corpuscle (composed of a glomerulus and Bowman's capsule/glomerular capsule) that filters the blood, kidney tubules that allow adjustment of urine contents and opportunities for ...

Are the nephrons functional microscopic units of the kidney?

The nephron is the microscopic structural and functional unit of the kidney. It is composed of a renal corpuscle and a renal tubule. The capsule and tubule are connected and are composed of epithelial cells with a lumen. A healthy adult has 0.8 to 1.5 million nephrons in each kidney. Lot more interesting detail can be read here.

What is the basic structure of the kidney?

Structure. The kidneys are two bean-shaped organs that are roughly the size of a fist. A tough, fibrous renal capsule surrounds each kidney and provides support for the soft tissue inside. Beyond that, two layers of fat serve as further protection.

What is the microscopic structure of the urinary system?

The structural unit of urine production in the kidney is a nephron. The nephron is a microscopic structure that is made of blood capillaries and a set of tubules made of kidney epithelium. Capillaries bring blood to the nephron where is gets filtered through the filtration membrane into the capsular space.

What are microscopic filters in the kidneys?

Each nephron in your kidneys has a microscopic filter, called a glomerulus that is constantly filtering your blood. Blood that is about to be filtered enters a glomerulus, which is a tuft of blood capillaries (the smallest of blood vessels).

What are microscopic structures?

Microscopic anatomy (micro; small) is a branch of anatomy that relies on the use of microscopes to examine the smallest structures of the body; tissues, cells, and molecules.

What microscopic structure is the functional unit of the kidney quizlet?

The glomerulus is one of the key structures that make up the nephron, the functional unit of the kidney.

What type of tissue is kidney?

The parenchyma of the kidney is epithelial tissue (mostly renal tubules). The blood vessels, nerves, and supporting connective tissue of the kidney comprise the stroma.

What is the histology of the kidney?

The kidney parenchyma consists of two layers; an outer cortex and inner medulla. They comprise around one million urine-producing nephrons. Urine is collected into a system of renal calyces, which is a series of distinctive chambers within a kidney.

What is the gross structure of the kidney?

Each kidney weighs about 125–175 g in males and 115–155 g in females. They are about 11–14 cm in length, 6 cm wide, and 4 cm thick, and are directly covered by a fibrous capsule composed of dense, irregular connective tissue that helps to hold their shape and protect them.

Are the functional microscopic units of the kidney?

Nephrons are the “functional units” of the kidney; they cleanse the blood of toxins and balance the constituents of the circulation to homeostatic set points through the processes of filtration, reabsorption, and secretion.

What is microscopic structure of cell?

A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.

How are microscopic structures different from macroscopic structures?

In the context of Chemistry, "microscopic" implies the atomic or subatomic levels which cannot be seen directly (even with a microscope!) whereas "macroscopic" implies things that we can know by direct observations of physical properties such as mass, volume, etc.

What are the parts of microscope and their functions?

These parts include:Eyepiece – also known as the ocular. ... Eyepiece tube – it's the eyepiece holder. ... Objective lenses – These are the major lenses used for specimen visualization. ... Nose piece – also known as the revolving turret. ... The Adjustment knobs – These are knobs that are used to focus the microscope.More items...•

What is microscopic examination of urine?

What It Is. Microscopic urinalysis is often done as part of an overall urinalysis. After a urine (pee) sample is collected, it's put into a centrifuge — a special machine that separates the liquid in the urine from any solid components that may be present, such as blood cells, mineral crystals, or microorganisms.

What can you see in a urine microscope?

It can see cells from your urinary tract, blood cells, crystals, bacteria, parasites, and cells from tumors. This test is often used to confirm the findings of other tests or add information to a diagnosis.

What type of tissue makes up the urinary system?

epitheliumUrinary bladder and urethra are consisting of epithelium on the lumen surrounded by a collagen rich connective tissue and muscle layer. The epithelial layer serves as a barrier that prevents the urine from sweeping into the body cavity.

How do you read a microscopic urine?

Normal values are as follows:Color – Yellow (light/pale to dark/deep amber)Clarity/turbidity – Clear or cloudy.pH – 4.5-8.Specific gravity – 1.005-1.025.Glucose - ≤130 mg/d.Ketones – None.Nitrites – Negative.Leukocyte esterase – Negative.More items...•

Abstract

Each of the paired kidneys is a complex, tubular gland comprised of numerous uriniferous tubules. The uriniferous tubule is the basic functional unit of the kidney.
