Stages of uterine prolapse describe the progressive descent of the
uterus from its normal position to protrusion outside the vagina,
causing pelvic pressure, discomfort, and urinary issues, depending
on severity.
Venous valve states. Comparison between the normal valve
and varicose veins, where the valve failure causes blood reflux,
blood accumulation, venous dilation, and symptoms such as
pain, swelling, and heaviness.
Stomach cancer. It represents the formation of malignant tumors
in the gastric mucosa that disrupts digestion, causing abdominal pain
pain, weight loss, and digestive symptoms, with a risk of progression if
not detected in time.
Stomach endoscopy. A diagnostic procedure that allows observing the
gastric interior using an endoscope, facilitating the detection of ulcers,
inflammation, and tumors, as well as the taking of biopsies for an
accurate diagnosis.
Stomach ulcer. A lesion in the gastric mucosa caused by
Helicobacter pylori or anti-inflammatories, which cause

Stress urinary incontinence is the involuntary leakage of urine
during activities that increase abdominal pressure, such as coughing
or lifting. Moreover, it is caused by pelvic floor weakness. Treatment
includes exercises, lifestyle changes, and surgery in severe cases.
Structure and formation of DNA. This double helix molecule
stores genetic information through sequences of nucleotides and
nitrogenous bases. Its enzymatic replication process allows the
precise transfer of the biological code during cell division for
inheritance purposes.
Subcapital femoral prosthesis is a surgical treatment for
severe fractures near the femoral head. Moreover, it replaces
damaged structures, relieving pain and restoring mobility.
Indication depends on patient age, health, and fracture severity.
The synapse in Alzheimer’s disease has an altered function in
neuronal communication. Moreover, under normal conditions,
synapses allow efficient signal transmission. Additionally, they
support memory and learning.
