• Anatomy of the Kidneys PowerPoint Diagram

Perfect for teaching anatomy or general health classes in a way that is simple for your students to visualize and understand, the Anatomy of the Kidneys PowerPoint Diagram is a diagram that shows all of the different parts of the kidneys and urinary system. The single slide is editable, but it already comes with clearly drawn lines and colors that make it easier for you to explain the unique, intricate parts of the system. From each aspect of the system stems a straight line that leads to the different names of the parts to make it easier to take notes.

The human kidneys are found on either side of the vertebrates in the lower back. They are shaped like beans and are about 4.3” in length. They receive blood through the renal arteries and there are exits for the blood thanks to the renal veins. As the human kidneys PowerPoint diagram demonstrates, their primary function is to remove the waste products in the blood which in turn are sent through the ureter tubes that are connected to the bladder. The human kidneys PPT provides an ample visual of how the process works.

For example, they show that on top of each kidney is an adrenal gland. Plus, the diagram helps people visualize the kidney inside their own bodies and how the process of filtering and cleaning blood works.

How Kidneys Work

The functional unit of the kidney is the nephron, of which about one million are found in each kidney. The nephron uses four processes which alter the flow of blood;

  • Filtration
  • Reabsorption
  • Secretion
  • Excretion

The filtration is contained in the glomerulus section, where about a fifth of the blood which enters the kidney is filtered. This means that the blood will have to pass through a kidney about five times before it becomes fully filtered of unwanted materials.

The reabsorption process occurs when substances that help the body function are put back into the blood stream. Some of the materials that may be reabsorbed include sodium, glucose, amino acids, bicarbonate, and solute-free water. This is followed by the secretion process which removes unwanted substances from the blood, such as ammonium, potassium, uric acid, and hydrogen. There are other elements and toxins which are secreted from the kidneys as well when the blood is filtered.

The excretion is seen when the unwanted material flows out of the kidney through the ureter and into the bladder. Called urine, the bladder holds the substance until it is voluntarily released from the body through the urethra tract.

Kidney Disease

If the kidney no longer functions the way it should, then it might be subject to disease that affects its ability to operate normally. The treatment of kidneys that are failing is usually along the lines of dialysis which helps to clean the blood independent of the kidneys or a full kidney transplant to replace the damaged organ.

A transplant generally occurs when the kidney drops below 15% in terms of renal function as this is considered when the kidney has failed.

In addition to the four major processes, there are functions which happen outside the influence of the nephrons. This includes functions such as converting Vitamin D to its active form in the body, which is called calcitriol, and to synthesize renin and erythropoietin which are hormones in the body.

For those who want to learn more about human kidneys, using a human kidneys PowerPoint diagram is a good place to start. The human kidneys PPT is an excellent way to teach how the kidneys function and their importance to the body in general.
