what are the main organs of excretory system
The human body is composed of many different organs and systems, all of which work together to allow us to survive and function. In this article, we will explore the main organs of the excretory system – the kidneys, bladder, and urethra.
The urinary system
The urinary system includes the kidneys, ureters, and bladder. The kidneys are a pair of organs located on either side of the spine that remove waste products from the blood. The ureters transport urine from the kidneys to the bladder. The bladder stores urine until it is emptied through the urethra.
The digestive system
The digestive system is responsible for breaking down food into smaller particles that can be absorbed by the body. The digestive system includes the stomach, small and large intestines, and the rectum and anus.
The stomach is a large organ located in the upper part of the large intestine. It is made up of two sections: the upper small intestine and the lower large intestine. The upper small intestine primarily absorbs water and food from the stomach, while the lower large intestine breaks down food into smaller pieces.
The small and large intestines are connected by the rectum and anus. The rectum acts as a temporary storage area for feces until it is eliminated through the anus. The anus is also responsible for cleaningse the body of toxins that have been eliminated through feces.
The reproductive system
The reproductive system includes all the organs and tissues that produce and support the new generation of cells. This system includes the reproductive organs, such as the ovaries, testes, and uterus. The reproductive system also includes the fluids and secretions that flow through these organs and help to create a new life.
The excretory system
The excretory system is responsible for eliminating waste materials from the body. The four main organs of the excretory system are the kidneys, the bladder, the ureters, and the rectum/anus. The kidneys are located at the back of the spine and filter blood to remove waste and toxins. The bladder stores urine until it is eliminated through the ureters. The rectum/anus transports feces from the intestines to the outside world.
Rectal system
The rectum is the final part of the excretory system that handles waste. It is a long, thin tube that starts at the anus and ends near the genitals. The rectum has two functions: it helps with bowel movements and it stores feces until it can be expelled through the rectum and out of the body.
Cecum
The cecum is the first and final section of the large intestine. It’s located in the lower right portion of the abdomen just below the navel. The cecum is about 6 to 8 inches long, 3 to 4 inches wide, and 1 inch thick. The surface of the cecum is covered with smooth muscle and hair.
The cecum is responsible for digesting food from the small intestine before it enters the large intestine. The cecum also helps to remove waste products from the large intestine.
The cecum is divided into four parts: the ascending colon, transverse colon, descending colon, and rectum. The ascending colon joins the small intestine at the ileocecal valve. The transverse colon runs through the middle of the cecum and then turns to go down the other side. The descending colon goes down one side of the cecum and then turns to go up the other side. The rectum wraps around the end of the cecum.
Appendix
The main organs of the excretory system are the kidneys, the bladder, and the intestines. The kidneys filter the blood to remove wastes and toxins. The bladder stores urine until it is released through the urethra. The intestines process food into nutrients and waste products.
Conclusion
The main organs of the excretory system are the bladder, kidneys, and liver. These organs work together to rid the body of waste products. The bladder stores urine until it is released through the urethra. The kidneys filter blood and remove waste products from it before releasing them into the urinary bladder. The liver converts food into energy that is used by the body.
