Anatomi Systema Uropoetica : Ren dan Ureter

Summary

This video provides an in-depth explanation of the uropoietic system, focusing on the kidneys and ureters. It covers the structure and functions of the kidneys, including their anatomical location, coverings, vascularization, and innervation. The video also discusses the ureters, their role in transporting urine from the kidneys to the bladder, and the conditions that can affect them, such as ureteritis and ureterolithiasis. Various clinical conditions, including nephritis, hydronephrosis, and kidney mobility, are also explored. The presentation is aimed at educating viewers on the essential components of the urinary system and its clinical relevance.

Takeaways

• 😀 The uropoietic system filters blood to eliminate unnecessary substances, which are eventually excreted as urine.
• 😀 The kidneys (Ren) are retroperitoneal organs located on the posterior abdominal wall, with the right kidney slightly lower due to liver displacement.
• 😀 The kidneys have four layers of protective coverings: fibrous capsule, perirenal fat, renal fascia, and pararenal fat.
• 😀 The kidneys are held in place by fixators such as renal fascia, renal veins, and adipose tissue. Significant weight loss can lead to kidney mobility or nephroptosis.
• 😀 The kidneys are anatomically positioned relative to other organs: they interact with the adrenal glands, stomach, pancreas, and intestines.
• 😀 The renal structure includes two main parts: the cortex (outer) and medulla (inner), which contain various anatomical features like renal pyramids and columns.
• 😀 Renal pyramids lead to renal papillae, which connect to the minor calyces, and then to the major calyces and renal pelvis, ultimately connecting to the ureters.
• 😀 The kidneys receive blood supply from the renal arteries, branching from the abdominal aorta. Blood is filtered in the glomeruli, with waste being excreted as urine.
• 😀 The kidneys are innervated by the renal plexus, with both sympathetic and parasympathetic fibers. Lymphatic drainage follows the renal and iliac nodes.
• 😀 Clinical conditions related to the kidneys include nephrolithiasis (kidney stones), nephritis (inflammation), and hydronephrosis (fluid buildup in the kidneys).

Q & A

What is the main function of the uropoietic system?

The main function of the uropoietic system is to filter blood, removing unnecessary substances and excreting them as urine.

Which organs are involved in the uropoietic system?

The uropoietic system includes the kidneys (Ren), ureters, urinary bladder (vesica urinaria), and urethra.

Where are the kidneys (Ren) located in the body?

The kidneys are located on the posterior wall of the abdomen, with the right kidney (Ren dextra) slightly lower due to the displacement caused by the liver.

What are the four layers surrounding the kidneys?

The four layers surrounding the kidneys are the fibrous capsule, perirenal fat (or corpus adiposum perirenale), renal fascia (fascia renalis), and pararenal fat (corpus adiposum pararenale).

What condition occurs when the kidney's position is affected due to the loss of perirenal fat?

This condition is called renal mobilis, which can progress to renal ptosis (kidney prolapse) in more severe cases.

What are the main features of the renal structure?

The kidney has a medial and lateral margin, an upper and lower extremity, and features such as the hilus renalis, where blood vessels and nerves enter and exit the kidney.

What are the key components found in the renal cortex and medulla?

In the renal cortex, structures like the renal columns (columna renalis) and cortical arches (arcus corticalis) are present. The medulla contains the renal pyramids (piramides renalis) and renal papillae (papilla renalis).

How is the blood supplied to the kidneys?

The kidneys are supplied by the renal artery, a branch of the abdominal aorta, which further branches into smaller arteries that supply the renal structures.

What is the role of the renal plexus in kidney function?

The renal plexus contains both sympathetic and parasympathetic fibers that innervate the kidneys, influencing functions such as blood flow and filtration.

What are the common clinical conditions related to the kidneys and ureters?

Common conditions include renal mobilis, hydronephrosis, nephrolithiasis (kidney stones), nephritis, ureteritis, and ureterolithiasis (stones in the ureter).
