Anatomi Fisiologi Sistem Perkemihan

Summary

In this educational video, Muji Rahayu from the Midwifery Program at Stikes Mitra Medan explains the urinary system. The video details the roles and functions of key organs: the kidneys, ureters, bladder, and urethra. The kidneys filter blood, regulate fluid balance, and manage ion balance. The video further describes processes such as filtration, reabsorption, and secretion in the kidneys. It also highlights how urine is transported through the ureters to the bladder, which stores it before it exits the body through the urethra. The explanation is both informative and thorough, ensuring viewers grasp the basics of the urinary system.

Takeaways

• 😀 The video discusses the urinary system and its role in eliminating metabolic waste and regulating fluid balance in the body.
• 😀 The kidneys, measuring 11.5 cm in length, 6 cm in width, and weighing 120-170 grams, are crucial organs in the urinary system.
• 😀 The shape of the kidneys is compared to a bean, highlighting their distinctive form.
• 😀 The kidneys have multiple functions, including filtering blood, regulating fluid volume, and maintaining ion balance in the body.
• 😀 Filtration in the kidneys occurs in the Bowman capsule, where the glomerulus filters the blood and eliminates waste products.
• 😀 Reabsorption takes place in the proximal tubule, where useful substances are reabsorbed back into the body.
• 😀 Secretion, or augmentation, occurs during the reabsorption process, which helps in further regulating waste removal.
• 😀 The ureter is a small tube that transports urine from the kidneys to the bladder.
• 😀 The bladder (vesica urinaria) serves as a storage organ for urine, holding between 350-450 mL before excretion.
• 😀 The urethra is the tube that carries urine from the bladder to the outside of the body, completing the process of urination.

Q & A

What is the main purpose of the video?

The main purpose of the video is to explain the urinary system, including its components and functions, in detail.

What is the size and weight of the kidneys?

The kidneys are 11.5 cm in length, 6 cm in width, and weigh between 120-170 grams.

What is the shape of the kidneys?

The kidneys are described as having a bean-like shape.

What are the primary functions of the kidneys?

The primary functions of the kidneys include filtering blood, regulating fluid volume in the body, and balancing ions in the body.

What is the process of filtration in the kidneys?

Filtration occurs in the Bowman capsule, where blood is filtered, and waste substances are removed from the body.

What is reabsorption in the kidney and where does it occur?

Reabsorption is the process where useful substances, like water and ions, are reabsorbed back into the bloodstream. This process takes place in the proximal tubule.

What is secretion in the kidney?

Secretion is the process where the kidneys remove substances that the body no longer needs, such as waste products or excess ions, after reabsorption.

What is the function of the ureter?

The ureter is a small tube that carries urine from the kidneys to the bladder.

What is the capacity of the bladder?

The bladder can hold between 350 to 450 mL of urine.

What role does the urethra play in the urinary system?

The urethra is a tube that transports urine from the bladder to the outside of the body, completing the elimination process.
