vaagnaõõt

Vaagnaõõt refers to the pelvic cavity in human anatomy. It is the space within the pelvis, bounded by the pelvic bones and the diaphragm of the pelvic floor. This cavity houses several important organs. In females, it contains the uterus, ovaries, fallopian tubes, cervix, vagina, bladder, and rectum. In males, it contains the seminal vesicles, prostate gland, bladder, and rectum. The structure of the pelvic cavity is crucial for supporting these organs and facilitating their functions, including reproduction, excretion, and locomotion.

The pelvic cavity is an irregular, somewhat funnel-shaped space. Its boundaries are formed by the sacrum and coccyx posteriorly, the ilium and ischium laterally, and the pubic bones anteriorly. The pelvic diaphragm, a muscular floor, separates the pelvic cavity from the perineum below. The shape and dimensions of the pelvic cavity can vary between individuals and are particularly important in obstetrics, where the maternal pelvis must accommodate the passage of a fetus during childbirth. Anatomical variations in the pelvic cavity can influence various physiological processes and may predispose individuals to certain medical conditions.
