- Vertebrates are the cool kids on the animal block, with a spine and all that jazz.
- Circulatory system? It’s like the postal service of your body, delivering nutrients and mail (waste) where they belong.
Meet the Blood-Pumping Marvel:
Now, let’s zoom in on this circulatory system of ours. It’s a closed loop, like a race track for blood, with a hard-working heart as the engine. The heart is a muscular master, pumping blood through a network of blood vessels. These are like tiny tubes of varying sizes:
- Arteries: The fancy highways, carrying nutrient-rich blood away from the heart to the rest of the body.
- Veins: The workhorses, carrying blood back to the heart after it’s done its delivery duties.
- Capillaries: The tiny alleyways, where all the action happens – oxygen and nutrients hop out, and waste products hop in.
The Oxygen Exchange Zone:
The circulatory system has a special sidekick: the lungs. When blood reaches the lungs, it’s up for a gas exchange party. Oxygen molecules, the life of the party, hop into the blood, while carbon dioxide, the party crasher, gets kicked out into the air. This freshly oxygenated blood then makes its way back to the heart, ready for another lap around the body.
The Nervous System: The Orchestrator of Life
Picture this: you’re taking a peaceful nap, and suddenly, someone tickles your nose. BAM! You instantly wake up, ready to defend your precious nasal passage.
That’s the power of your nervous system, folks! It’s the control center of your body, making sure everything runs smoothly, from breathing to thinking.
