Sístole y diástole: cómo funciona el latido del corazón

El corazón funciona como una bomba muscular que impulsa la sangre por todo el cuerpo. Para lograrlo realiza un ciclo continuo compuesto por dos fases principales: sístole y diástole. Estas fases permiten que la sangre salga del corazón y luego vuelva a llenarlo para el siguiente latido.

Sístole

La sístole es la fase en la que el corazón se contrae.

Cuando el músculo cardíaco se contrae, los ventrículos expulsan la sangre hacia las arterias:

El ventrículo izquierdo envía sangre al cuerpo a través de la aorta.

El ventrículo derecho envía sangre a los pulmones para que se oxigene.

Durante esta fase ocurre la salida de la sangre del corazón hacia el resto del organismo.

Diástole

La diástole es la fase en la que el corazón se relaja.

Al relajarse el músculo cardíaco, las cavidades del corazón se llenan nuevamente de sangre que llega desde las venas. Esto prepara al corazón para el siguiente latido.

En esta fase ocurre la entrada de sangre al corazón.

Relación con la presión arterial

Cuando se mide la presión arterial aparecen dos valores que corresponden a estas fases:

Presión sistólica: presión cuando el corazón se contrae.

Presión diastólica: presión cuando el corazón se relaja.

Por ejemplo, una presión de 120/80 mmHg indica:

120: presión durante la sístole

80: presión durante la diástole

Este ciclo ocurre de forma continua, aproximadamente 60 a 100 veces por minuto en un adulto en reposo.

Research shows that men can usually sleep through nearly any noise at night, but after giving birth, women experience a profound change. Childbirth causes a permanent enlargement of the amygdala, the part of the brain responsible for alertness, fear, and emotional processing. This change keeps mothers constantly vigilant, even while they sleep.

The enlarged amygdala is nature’s way of ensuring infant survival Mothers are biologically primed to respond to the slightest cry or movement from their baby, making them hyper-aware and protective 24/7. While this heightened alertness can be exhausting, it plays a crucial role in nurturing and safeguarding newborns.

Understanding this remarkable transformation highlights the biological power of motherhood It explains why many new mothers feel perpetually “on duty” and why sleep deprivation feels different for them compared to other adults. Motherhood doesn’t just change daily life—it rewires the brain for life.

THE GHOST ORGAN THAT WAS ALWAYS THERE.

imagine opening a 2015 anatomy book You'll see skin, then fat, then muscle. All packed up like solid dense layers. Now throw that book away.. I was wrong.

Until very recently, histologists (scientists who study tissue) prepared samples by drying them and fixing them in microscopes. By doing so, they destroyed the actual structure. The spaces were collapsing.

In 2018, thanks to new live endomicroscopy technologies, we discovered Interstition.

We ain't "solid". Underneath your skin, covering your arteries, your lungs, and your muscles, there is a massive network of interconnected compartments filled with liquid. It's like a global hydraulic damper. A highway of fluids that connects everything to everything.

Why is this revolutionary in 2026?.

The route of metastasis: It has been found that

cancer cells often don't travel through blood or lymph initially, but rather use these "highways" of the interstice to move quickly between tissues. Understanding this is changing oncology.

Validation of Ancestral: For thousands of years, Traditional Chinese Medicine spoke of "Meridians" or energy channels (Qi) that did not correspond to nerves or veins. Western science was mocking. Today, many researchers propose that the Interstition, with its high electrical conductivity thanks to the fluid rich in electrolytes, could be the physical anatomical base of those meridians. Acupuncture needle doesn't poke a nerve; it stimulates the facial/interstitial network, sending mechanical signals throughout the system.

Your body is a continuous hydraulic system. The stiffness in your ankle can affect your neck because the fluid network is the same. The "stagnation" of fluids that the Ancients spoke of now has a scientific name.

Keeping this organ healthy is vital. How? Hydration and Movement. The interstition needs you to move to pump its fluids. If you stay still, it becomes sticky, dense, and toxic.

You're 70% water, but that water ain't stuck in a bucket. It's flowing through a sacred, complex architecture that we're just beginning to understand.

TIP YOURSELF (Facial Health):

"To keep your interstition fluent and avoid morning stiffness:

Hydration with Electrolytes: Water alone isn't enough. Interstitial fluid is rich in salts. Add a pinch of sea salt to your water.

Bounce (Rebounding): Gentle jumps or oscillatory movements help move interstitial fluid better than static cardio.

Myofascial Release: Using foam rollers helps rehydrate these compressed layers of tissue. "
