Everything about PEE💧

1. Humans should urinate at least four to six times a day, but occasionally, the pressures of modern life force us to clench and hold it in. Two kidneys, two ureters, two urethral sphincters, and a urethra. 2. Constantly trickling down from the kidneys is the yellowish liquid known as urine. The kidneys makeurine from a mix of water and the body's waste products, funneling the unwanted fluid into two muscular tubes called ureters. 3. These carry it downward into the hollow organ known as the bladder. This organ's muscular wall is made of tissue called detrusor muscle, which relaxes as the bladder fills allowing it to inflate like a balloon. 4. As the bladder gets full, the detrusor contracts. The internal urethral sphincter automatically and involuntarily opens, and the urine is released. When you want to delay urinating, you keep the sphincter closed. When you want to release it, you can voluntarily open the flood gates. 人应该每天至少排尿四到六次，但有时候，现代生活的压力迫使我们紧紧地憋住。两个肾脏，两条输尿管，两个尿道括约肌，和一个尿道。 不断地从肾脏淌下来的是被称为尿液的黄色液体。肾脏所产生的尿液是水和身体废物的混合，将不需要的液体输送到两条称为输尿管的肌肉管中。 这两条输尿管将尿液向下输送到被称为膀胱的空心器官。这个器官的肌肉壁是由被称作排尿肌的组织构成的，当膀胱充盈时，排尿肌会放松，使其像气球一样膨胀起来。 当膀胱变满时，排尿肌会收缩。内部的尿道括约肌自动地、不由自主地打开，尿液被排出。当你想延迟排尿时，你要保持括约肌关闭。当你想释放它时，你可以主动地打开闸门。
