Cancerous prostate is a common malignant tumor in older men
caused by uncontrolled prostate cell growth. Moreover, it may cause
urinary symptoms and spread to other organs. Diagnosis includes PSA
testing and biopsy, while treatment depends on stage and progression.
Cortisol production occurs in the adrenal cortex after
ACTH stimulation from the pituitary. It regulates
metabolism, blood pressure, and the body’s response
to stress.
Cortisol secretion occurs in the adrenal cortex after
stimulation by ACTH from the pituitary. It regulates
metabolism, blood glucose, and the stress response
through the endocrine axis.
The female urinary system includes the kidneys, ureters,
bladder, and urethra. It filters blood, produces urine, and
allows its transport, storage, and elimination, maintaining
body balance.
Kidney anatomy describes bilateral bean-shaped organs located in the retroperitoneum. They filter blood, produce urine, and regulate fluid, electrolyte, and pH balance in the body.
Kidney anatomy and physiology explain its internal
structure and functions. They include filtration, urine
formation, and regulation of water, electrolytes, and
pH, along with adrenal gland activity.
Kidney physiology explains how these organs filter blood, remove waste, and regulate water, electrolytes, and pH. They also perform essential hormonal functions to maintain body balance.
The kidney representation shows a sagittal section with
cortex, medulla, and renal pelvis. It helps understand
internal structure, filtration, urine formation, and fluid
regulation.
The prostate lies below the bladder and surrounds the urethra.
It produces prostatic fluid that forms part of semen, while the
bladder stores and expels urine in the male urinary system.
The bladder wall consists of mucosa, submucosa, detrusor
muscle, and serosa. These layers allow expansion, storage,
and contraction of the bladder during urination.
The male bladder is a hollow muscular organ in the
pelvis that stores urine. It is closely related to the
prostate, which surrounds the urethra and influences
urinary flow and function.
The male urinary system includes the kidneys, ureters,
bladder, and urethra. It filters blood, produces urine, and
allows its transport, storage, and elimination, maintaining
body balance.
