@varela 🤍:@Mariaaa: The heart functions as a double, continuous muscle pump that beats approximately 100,000 times a day to keep blood in constant movement throughout the body. Physiologically, this organ is divided into four cavities: an upper two called the atria, which receive blood, and a lower two called the ventricles, which expel it. The cycle begins when deoxygenated blood from the entire body returns to the heart through the venae cavae and enters the right atrium. This cavity contracts and pushes blood through the tricuspid valve into the right ventricle, which, upon contracting, sends blood to the lungs via the pulmonary artery, where the blood releases carbon dioxide and is recharged with fresh oxygen. Once oxygenated, the blood returns to the heart through the pulmonary veins and enters the left atrium. From there, it passes through the mitral valve to the left ventricle, which is the thickest and most powerful cavity in the heart, responsible for pumping the blood with great force into the aorta artery to distribute it throughout the body. All this mechanical movement is perfectly coordinated by an intrinsic electrical system that generates its own impulses; electrical travel initiates at the sinus node, the natural pacemaker located in the right atrium, which sends a signal for both atria to contract simultaneously. This current then travels to the atrioventricular node and spreads rapidly through the ventricles through the His bundle and Purkinje fibers, causing ventricular contraction. This cyclic process consists of two main phases: diastole, which is the moment of relaxation where the cavities are filled with blood, and systole, which is the phase of contraction and emptying, thus ensuring an vital flow. IT DOES NOTHING HARD FOR YOU TO COPY AND HIT. ❤️🩹

people just sending 1 singular unserious sticker does NOT help btw long comments help better. for everyone who is struggling, please hold on. there is someone out there meant to be the person who holds you on those hard nights, there is a better road ahead and i know it is hard to see it right now. it will get better, you have probably heard it a thousand times, it gets annoying but i promise you, in a few years when you are healed it will be something you look back on. if you have people to text, whether its family or friends, you have reasons to stay. one day at a time, grab a coffee with a friend, rip up a page of homework you just cant figure out, go out and enjoy the world in the night when its quiet. you do not need to prove you are enough to someone who sees what you don’t see in yourself. you are more than just a daughter or son or child, more than just a person. you are unique, with your hobbies, your life, your humor, your skills, your interests. there is a better road ahead, don’t let yourself derail before you see it. i know it is hard, but you are worth more than what you see in the mirror, you are worth more than the empty words that one voice in your head constantly tells you. your story isnt over for a reason, because there is something better for you just out of reach and you deserve to be able to reach it. you are loved, even when it doesnt feel like it. you are loved, even when you dont want to hear it. you are enough, even with a failing grade or having to stretch money out for your kiddos. you are doing amazing, even though you dont see it.
