What are the parts of the excretory system?

What are the parts of the excretory system?

Organs of excretion make up the excretory system. They include the kidneys, large intestine, liver, skin, and lungs. The kidneys filter blood and form urine. They are part of the urinary system, which also includes the ureters, bladder, and urethra.

What are the 3 parts of the excretory system?

There are several parts of the body that are involved in this process, such as sweat glands, the liver, the lungs and the kidney system. Every human has two kidneys. Each kidney is made up of three sections: the renal cortex, the renal medulla and the renal pelvis.

What are the 4 main parts of the urinary system?

The urinary system’s function is to filter blood and create urine as a waste by-product. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra.

Which of the following organs is not a part of the excretory system?


What is the correct order of excretory system?

So, the correct order of the organs of the human excretory system is Kidneys, ureters, urinary bladder and urethra.

What are the types of excretion?

Modes of Excretion

  • Ammonotelism (Type of excretion- ammonia)
  • Ureotelism (Type of excretion – urea)
  • Uricotelism (Type of excretion – uric acid)
  • Aminotelism (Type of excretion – amino acids)
  • Guanotelism (Type of excretion – guanine)

How many types of excretory systems are there?

This is not to say, however, that each invertebrate phylum has evolved its own particular type of excretory organ; rather, there appear to be five main types of invertebrate excretory organ: contractile vacuole, nephridium, renal gland, coxal gland, and malpighian tubule.

What is the major parts of nephron?

A nephron is made of two parts:

  • a renal corpuscle, which is the initial filtering component, and.
  • a renal tubule that processes and carries away the filtered fluid.

What are parts of nephron?

Each nephron is composed of a renal corpuscle (glomerulus within Bowman’s capsule), a proximal tubule (convoluted and straight components), an intermediate tubule (loop of Henle), a distal convoluted tubule, a connecting tubule, and cortical, outer medullary, and inner medullary collecting ducts.

How long is a nephron?

Each nephron in the mammalian kidney is a long tubule, or extremely fine tube, about 30–55 mm (1.2–2.2 inches) long. At one end this tube is closed, expanded, and folded into a double-walled cuplike structure.

Why nephron is called dialysis bag?

Glomerulus are considered as dialysis bags because in nephron glomerulus filters the blood by not absorbing unwanted salts and urea back ,also by dialysis machine filteration of blood is done but artificialy. Therefore,we can say that glomerulus is considered as dialysis bag.

What is the name of the vein that takes blood away from the nephron?

The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. They carry the blood filtered by the kidney.

What is the meaning of inferior vena cava?

The inferior vena cava (or IVC) is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins, usually at the level of the fifth lumbar vertebra.

What is the function of the inferior vena cava?

The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis. The vena cava is the largest vein in the body.

Can you live without an inferior vena cava?

Absence of the inferior vena cava is a rare vascular anomaly, which usually remains asymptomatic in childhood. It is recognized as the risk factor for deep venous thrombosis, since the collateral circulation does not provide adequate drainage of the lower limbs.১৪ এপ্রিল, ২০১৫
