Lymphatic breast cancer. Lymph node involvement by
tumor cells originating from breast tissue, indicating
cancer dissemination and greater clinical complexity in its
treatment.
Normal eye focus. This illustration presents the path of light
through the cornea and lens to the retina. The graphic shows the
transformation of light signals into electrical impulses for brain
processing, ensuring a sharp and detailed vision of the
surroundings.
The open aortic valve stenosis has an altered function in
systemic circulation. Moreover, under normal conditions,
the aortic valve opens fully. Additionally, it allows efficient
blood passage.

Phases of venous valves. 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.

Severe hypercholesterolemia involves very high cholesterol and
triglyceride levels, leading to plaque buildup, reduced blood flow,
and increased risk of heart attack and stroke, often without early
symptoms.
The single-chamber pacemaker has a general function in
regulating the heart rhythm. Moreover, under normal conditions,
the heart’s electrical system coordinates beats. Additionally, it
allows an adequate heart rate.
A single-chamber pacemaker uses one lead connected to either
the atrium or the ventricle (usually the right) to regulate the heart
rhythm. It senses electrical activity and sends pulses if the heart
beats too slowly. It is simple and effective.
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.
The Tetralogy of Fallot has an altered function in blood oxygenation.
Moreover, under normal conditions, the heart separates oxygenated
and deoxygenated blood. Additionally, it allows efficient circulation.
