Have you ever wondered how each cell in your organism receives its nutrients and eliminates its waste? Well, there's a complex and sophisticated system for this - your blood!
Blood: Your Body's Logistics System
As you may know, one of the main functions of blood, that red liquid that flows from within you and causes some people to faint just by looking at it, is transport. Just like our logistics systems are made up of road networks with their cars, vans, and trucks of all kinds, blood floods networks of blood vessels through which different types of cells and substances circulate.
The Delivery and Recycling System
The substances transported by blood are all premium and must reach their destinations. Through blood travel nutrients, necessary for each cell to perform its function, the oxygen essential for obtaining energy, and also metabolic waste - that is, what is produced after using those nutrients and oxygen. As you know, the carbon dioxide produced as a consequence of using oxygen for energy is eliminated via the lungs. But many of the products obtained from chemical reactions produced in cells are transported in the blood to other destinations where they can be transformed and reused for other functions. We have a complete recycling and utilization system!
Correspondence: Letters and Telegrams
Messages that keep the entire organism in balance are sent through the blood. Messages that tell some cells when to grow, when to strive to do their work, or when to rest to save energy. In an organism of billions of cells, there must be a good communication system so that everything doesn't fall apart. A very important pathway of this communication system is the endocrine system, the Mail program that regulates all hormonal messages transmitted through blood.
Hemothermy
If you have radiators at home, perhaps you've thought about changing your boiler for an aerothermal one. Did you know that your body has its own radiator system through blood? Indeed, blood, besides transporting endless chemical signals, also transports heat from one place to another in the organism. Additionally, the vascular system can respond to external temperature to reduce or increase surface circulation depending on whether it needs to gain or lose heat.
Maintenance and Security
You may have seen those large vans on the road marking repair zones with cones and lights. Well, blood also has a system of operators, platelets, which together with different coagulation factors can repair injuries. And of course, we also have our security force, with their white uniform - none other than white blood cells. Different law enforcement bodies, some armed with antibodies, patrol the entire organism using the circulatory system to monitor every corner and protect us from external agents trying to invade us.
In Conclusion
As you can see, blood has a lot to it. Numerous cells and substances circulate through it to carry out the body's functions. Remember to keep our roads and operators healthy, always with regular physical activity and a balanced and sufficient diet.
