It is classically described that there are three sites in the ureter where a kidney stone will commonly become stuck: where the ureter meets the renal pelvis; where the iliac blood vessels cross the ureters; and where the ureters enter the urinary bladder, [9] however a retrospective case study, which is a primary source, of where stones lodged ...
Anura is an order of animals in the class Amphibia that includes frogs and toads. More than 5,000 species are described in the order. More than 5,000 species are described in the order. The living anurans are typically divided into three suborders: Archaeobatrachia , Mesobatrachia , and Neobatrachia .
The dual function of excretory systems is the elimination of the waste products of metabolism and to drain the body of used up and broken down components in a liquid and gaseous state. In humans and other amniotes ( mammals , birds and reptiles ), most of these substances leave the body as urine and to some degree exhalation, mammals also expel ...
Urine is excreted through the renal papillae into the calyces and then into the pelvis, ureter, and bladder. [62] [28] Then it is excreted outside through the urethra. [64] In monotremes, the ureters open into the urogenital sinus, which is connected to the urinary bladder and cloaca, [65] and urine is excreted into the cloaca instead of the ...
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH.
Pseudis paradoxa, known as the paradoxical frog or shrinking frog, is a species of hylid frog from South America. [2] Its name refers to the very large—up to 27 cm (11 in) long— tadpole (the world's longest), which in turn "shrinks" during metamorphosis into an ordinary-sized frog, only about a quarter or third of its former length.
There are 11 distinct organ systems in human beings, [2] which form the basis of human anatomy and physiology. The 11 organ systems: the respiratory system, digestive and excretory system, circulatory system, urinary system, integumentary system, skeletal system, muscular system, endocrine system, lymphatic system, nervous system, and ...
Adults are capable of jumping many times their height and length, giving the group their common name, but many species are best known for their plant-sucking nymphs which produce foam shelters, and are referred to as "spittlebugs".
