Did you say "under the ribs" or "inside the ribs"? Inside the ribs are the lungs, the lower left is the spleen, the middle is the left lobe of the stomach and liver, and the right is the right lobe of the liver and gallbladder. A little lower or so, there are kidneys on both sides. Its center and lungs are in the cavity called "chest" above, and it is the protagonist of the rib protector. If you mean below the ribs, it is the upper part of the abdominal cavity, mainly including the stomach, small intestine (duodenum, etc. ), large intestine (transverse colon), liver and gallbladder, pancreas, etc. And then the abdominal cavity goes down, and those places are far from the ribs.

Internal organs include all organs of digestive system, respiratory system, urinary system and reproductive system.

Digestive system: the pipeline from oral cavity to anus (esophagus, stomach, small intestine, large intestine, etc.). ) and digestive glands (salivary glands, liver, pancreas, etc. ) It is open here.

Respiratory system: nose, pharynx, larynx, trachea, bronchus and lungs.

Urinary system: kidney, ureter, bladder and urethra.

Reproductive system: internal genitalia (including gonads, reproductive ducts and accessory glands) and external genitalia (mainly bisexual organs). Male gonad is testis, reproductive tract is epididymis, vas deferens and ejaculatory duct, accessory gland is prostate, seminal vesicle and urethral gland, and external genitalia is penis and scrotum. Female gonad is ovary, reproductive tract is fallopian tube, uterus and vagina, and external genitalia is labia majora, labia minora and vestibular gland. [ 1]?

Visceral organs have different shapes, according to which hollow organs and parenchymal organs can be constructed.

Viscera are mainly concentrated in the chest, abdomen and pelvic cavity, which can be observed according to manual marking and division.

structure of the human body

The distribution of human viscera structure mainly includes the distribution of viscera in the chest and abdomen: the location map of important organs such as throat, trachea, lung, heart, liver, gallbladder, stomach, kidney, small intestine, spleen, rectum, duodenum, pancreas, ureter and bladder.
