“20.2 Graphical representation of vectors (ESAGK)
Vectors are drawn as arrows. An arrow has both a magnitude (how long it is) and a direction (the direction in which it points). The starting point of a vector is known as the tail and the end point is known as the head.”
The <u>bladder </u>is in the hypogastric region.
Hypogastric Region- The structures around the pelvic bone are located in the hypogastric area. These include the prostate in men and the womb and ovaries in women, as well as the bladder, a section of the colon and rectum, the anus, and several reproductive system organs.
Bladder- A little above and behind pubic bone in the pelvis, the urine bladder is a muscular sac. The bladder is roughly the size and shape of a pear when it is empty. The kidneys produce urine, which then passes via capillary called ureters and into the bladder. Urination can be restricted and rare because to the bladder's ability to hold pee.
