The Important Elements in the Kidney Diagram 

Kidney is one of the most beautifully engineered and complex organs in the body. The kidneys have several tasks that are important for the whole body, like waste products excretion, maintenance of the body’s homeostatic balance and the releasing of the important hormones. In order to fully achieve this, the kidney diagram should be properly refined. 

The Basic Structure of the Kidneys and their Location 

The location of the kidneys is at the back, near the vertebral column. The right kidney is located a little lower than the left one. When it comes to the structure and the function of the two kidneys, they are similar. They are both bean-shaped and have a dimension of 10 cm in length and 6.5 cm in width. The kidney has an inner medulla and an outer cortex. The renal artery supply oxygenated blood to the kidney.

Nephron 

Nephron is the kidney’s main functional unit. There are about a million of nephrons in each kidney. The nephrons are making urine by the following:

  • Filtering the blood with small molecules and ion, like water, glucose, salt and other soles. The large molecules, called “Macromolecules”, are untouched.
  • Allowing waste molecules and ions, or surplus, to flow from the ureter as urine.
  • Recycling the quantities of useful solutes that are required, which have bloodstream re-enrty.

 

Kidney’s Filtration and Re-absorption 

After the process in neuphron, solutes, such as potassium, glucose, sodium chloride and water, are reabsorbed into the bloodstream. This process is maintaining the correct balance of the chemicals in the blood, like assisting of the regulation of the blood pressure. The levels of blood sugars are well maintained by the re-absorption of the glucose to the blood. However, when the regulation breaks down, the tendency is to have serious health consequences. 

Nitrogen, like urea and uric acid, is containing waste products gathered by the body’s metabolic processes. The kidneys excrete these substances to maintain good health in the body, as they are toxic. Actually, 1% of these substances have left the body due to the different re-absorption processes that these substances undergo, like osmosis, active transport and diffusion.

 

Tubular Secretion 

Another process that is undergoing in the diagram of the kidney is the tubular secretion. There are specialized cells that move the solutes from blood directly to tubular fluid. The tubular secretion of the hydrogen ions is very important as it maintains the correct pH in the blood. Hydrogen ions will be secreted once the blood is too acidic. Hydrogen ions will be reduced once the blood is too alkaline. Once the blood pH is maintained to its normal level, the urine the kidney produced will have a pH as alkaline as baking soda or as low as of the acid rain.

 

Endocrine Gland 

The kidney also excretes important hormones to the blood. Erythropoietin is a hormone that increases the red blood cells production and acts on the bone marrow. Calcitriol is another hormone that promotes the calcium absorption from the food you take. It acts directly to the bones for the calcium to be shifted to the bloodstream.

 

This kidney diagram shows how the kidney is working and the important elements in the kidney.
