Ureters
Illustration of a ureter wall
Each ureter is a small tube, about 25 cm long, that carries urine from the renal pelvis to the urinary bladder. It descends from the renal pelvis, along the posterior abdominal wall, which is behind the parietal peritoneum, and enters the urinary bladder on the posterior inferior surface.
The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle. The main function of this layer is peristalsis: to propel the urine. The inner layer, the mucosa, is transitional epithelium that is continuous with the lining of the renal pelvis and the urinary bladder. This layer secretes mucus, which coats and protects the surface of the cells.
so whats the answer
the answer is A
The correct answer is A. Away from.
To learn this answer, it is helpful to have a basic understanding of the urinary system. The urinary system consists of the kidneys, ureters, bladder, and urethra, and it is responsible for removing waste products from the body in the form of urine.
To determine the direction in which the ureters carry urine, we need to know the starting and ending points. In this case, we know the starting point is the kidneys. The kidneys are the organs that filter the blood and produce urine. Therefore, the urine travels from the kidneys through the ureters.
The ureters are long, muscular tubes that connect the kidneys to the bladder. They carry urine away from the kidneys towards the bladder, where the urine is stored until it is ready to be eliminated from the body through the urethra.
Therefore, the ureters carry the urine away from the kidneys, making option A. "Away from" the correct answer.
