Anatomy of the Kidneys
The kidneys play a critical role in the urinary system, which filters blood and removes waste products in the form of urine. The kidneys are two bean-shaped organs located on either side of the spine, below the ribcage. Each kidney is about the size of a fist and weighs approximately 120-150 grams.
The kidneys are comprised of three main parts:
- The renal cortex: This is the outer layer of the kidney and is the site of filtration.
- The renal medulla: This is the middle layer of the kidney and contains the renal pyramids, which are responsible for the production of urine.
- The renal pelvis: This is the innermost part of the kidney and is the area where urine collects before it travels down the ureter and into the bladder.
The kidneys are supplied with blood from the renal arteries, which branch off the aorta. Blood is then filtered through tiny units called nephrons, which are responsible for the removal of waste products and excess fluids from the blood. Urine is then transported through the ureters to the bladder, where it is stored until it is expelled from the body via the urethra.
Functions of the Kidneys
The kidneys are a pair of bean-shaped organs located on either side of the spine in the lower back. They are an essential component of the urinary system and play a crucial role in maintaining homeostasis in the body. The primary function of the kidneys is to filter blood, removing waste products and excess water, and producing urine.
- Regulating Fluid Balance – The kidneys help regulate the balance of fluids and electrolytes in the body by adjusting the amount of urine produced. They are responsible for maintaining proper hydration levels by either conserving or excreting water, depending on the body’s needs.
- Eliminating Waste Products – The kidneys remove waste products from the blood, such as urea, creatinine, and ammonia. These waste products are produced by the body’s metabolism and, if allowed to accumulate, can cause damage to the body’s organs and tissues.
- Regulating Blood Pressure – The kidneys help regulate blood pressure by producing hormones that constrict or dilate blood vessels. They also help regulate the balance of sodium and potassium in the body, which can impact blood pressure levels.
In addition to their primary functions, the kidneys also perform other important tasks, including producing erythropoietin, a hormone that stimulates the production of red blood cells, and activating vitamin D, which is essential for healthy bones.

Overview of the Hematic System
The hematic system is responsible for maintaining the proper balance of fluids, electrolytes, and nutrients in the body. It is composed of different organs, including the heart, blood vessels, and blood. These organs work together to transport oxygen, nutrients, and waste products to and from different parts of the body. Additionally, the hematic system has several important functions in the immune system, such as helping to fight off infections and diseases. The kidneys, while not directly part of the hematic system, play a crucial role in maintaining the balance of fluids and electrolytes within the system.

Blood Vessels Connected to the Kidneys
The kidneys are not just vital organs for filtering out waste and excess fluids from the body, but they also play an important role in maintaining the body’s blood pressure and producing hormones that regulate red blood cell production. Given their critical functions, the kidneys need to be supplied with oxygen and nutrients via blood vessels, and any interruption in the blood supply can cause serious harm to the kidneys.
- The renal arteries are the blood vessels that bring oxygen-rich blood to the kidneys. They branch off from the abdominal aorta, which is the main artery that delivers blood from the heart to the rest of the body. The renal arteries are relatively small, but they have to deliver a large volume of blood to the kidneys, which require about 20% of the body’s cardiac output.
- Inside the kidneys, the renal arteries divide into smaller and smaller vessels called arterioles, which eventually lead to a network of capillaries known as glomeruli. The glomeruli are the site of blood filtration, where the waste and excess fluids are separated from the blood and removed from the body as urine.
- The filtered blood then leaves the glomeruli and enters a network of small veins called venules, which eventually merge into larger and larger renal veins. The renal veins carry the filtered blood back to the heart, where it can be re-circulated to the rest of the body.
Any damage or blockage to the renal arteries or veins can impair kidney function and cause a range of symptoms, including high blood pressure, fluid retention, and electrolyte imbalances. In some cases, a complete blockage of the renal arteries can lead to kidney failure, which requires immediate medical attention.
Therefore, it is crucial to maintain a healthy cardiovascular system to ensure proper blood flow to the kidneys and prevent any complications. This includes adopting a balanced diet, regular exercise, maintaining a healthy weight, and managing any underlying medical conditions such as high blood pressure or diabetes.
Here’s a table summarizing the blood vessels connected to the kidneys:
| Blood Vessel | Function |
|---|---|
| Renal Artery | Delivers oxygen-rich blood to the kidneys |
| Arterioles | Divides the renal artery into smaller vessels that lead to the glomeruli |
| Glomeruli | Site of blood filtration where waste and excess fluids are separated from the blood |
| Venules | Carries the filtered blood out of the glomeruli and into the renal veins |
| Renal Vein | Carries the filtered blood back to the heart |
By understanding the blood vessels connected to the kidneys and how they function, we can appreciate the importance of healthy kidney function and take steps to maintain it.
Common Kidney Disorders
The kidneys are vital organs in the body that remove waste and excess fluids from the blood. They are a part of the urinary system, but they also play a role in the hematic system. Kidney disorders can lead to a buildup of waste in the body, causing problems such as high blood pressure, anemia, weak bones, nerve damage, and kidney failure.
- Chronic Kidney Disease (CKD): This is a long-term condition where the kidneys gradually lose function over time. CKD may result from diabetes, high blood pressure, or other conditions that damage the kidneys. Symptoms of CKD include fatigue, swelling in the legs and feet, loss of appetite, and trouble sleeping.
- Kidney Stones: These are hard, mineral deposits that form in the kidneys and can cause extreme pain when they move through the urinary tract. The most common symptom of kidney stones is severe pain in the back, side, or groin. Other symptoms may include a frequent urge to urinate, blood in the urine, or nausea and vomiting.
- Polycystic Kidney Disease (PKD): This is an inherited condition where fluid-filled cysts develop in the kidneys, causing them to grow in size and lose function over time. PKD may not cause any symptoms in its early stages, but as the cysts grow, they can lead to high blood pressure, back or side pain, and kidney failure.
Other common kidney disorders include urinary tract infections, kidney infections, and glomerulonephritis (inflammation of the kidney’s filtering units). Treatment for kidney disorders varies depending on the type and severity of the condition and may involve medications, lifestyle changes, or in severe cases, dialysis or kidney transplant surgery.
Below is a table summarizing the common kidney disorders:
| Kidney Disorder | Causes | Symptoms | Treatment |
|---|---|---|---|
| Chronic Kidney Disease (CKD) | Diabetes, high blood pressure, other conditions | Fatigue, swelling, loss of appetite, trouble sleeping | Medications, lifestyle changes, dialysis, kidney transplant |
| Kidney Stones | Mineral buildup in the kidneys | Severe pain, frequent urination, blood in the urine, nausea/vomiting | Pain medication, drinking water, surgery (in severe cases) |
| Polycystic Kidney Disease (PKD) | Inherited condition | High blood pressure, back/side pain, kidney failure | Treat symptoms, dialysis, kidney transplant |
If you experience any symptoms of kidney disorder or are at risk due to underlying health conditions, it is important to speak with your healthcare provider and get recommended screenings and tests to ensure early detection and prompt treatment.
Impact of Kidney Disease on the Hematic System
When kidneys are healthy, they play a crucial role in the hematic system by filtering waste and excess fluids from the blood. But when kidney function begins to decline or fails altogether, the entire hematic system can be impacted. Here are some of the key effects of kidney disease on the hematic system:
- Anemia: Kidneys produce a hormone called erythropoietin (EPO) that stimulates the production of red blood cells. When kidneys are damaged or not functioning properly, EPO production decreases, leading to a condition called anemia. Anemia can cause fatigue, weakness, and shortness of breath.
- Iron Deficiency: Another effect of kidney disease on the hematic system is iron deficiency. Iron is necessary for the production of red blood cells, and healthy kidneys help regulate iron levels in the body. When kidneys are damaged, iron levels can decrease, leading to anemia and other health problems.
- Blood Pressure Regulation: Kidneys play a vital role in regulating blood pressure. When kidney function is compromised, blood pressure can rise, leading to hypertension. Hypertension can damage blood vessels and increase the risk of heart disease and stroke.
Beyond these impacts, kidney disease can also lead to a range of other hematic system disorders, including:
- Macro- and Microvascular Complications: Kidney disease can damage blood vessels throughout the body, leading to macro- and microvascular complications such as peripheral arterial disease, coronary artery disease, and stroke.
- Proteinuria: Kidney damage can cause proteins to leak into the urine, a condition known as proteinuria. This can lead to additional health problems, including edema (swelling) and high cholesterol levels.
- Bleeding Disorders: In rare cases, kidney disease can cause bleeding disorders that affect the ability of the blood to clot properly.
| Effect of Kidney Disease on the Hematic System | Description |
|---|---|
| Anemia | Kidneys produce the hormone EPO that stimulates red blood cell production. When kidneys are damaged, EPO production decreases, leading to anemia. |
