#cardiovascular system

Alhamdulilah ❤️❤️❤️

•Your brain isn't done forming until you're 25 years old

•Your brain is the fattiest organ in the human body, being made up of 60% fat (roughly)

•Your spinal cord, unlike your brain, stops developing at 4 years old

•Your tailbone is actually very important to your body as it's where ligaments and muscles attach for your pelvis, as well as helps distribute weight and gives you support while you sit down.

•an adult brain is about 3 pounds

•the texture of a brain is like a firm jelly

•your muscles are what produces your body's heat, which is why you heat up while moving and cool off while sitting still (it's much more drastic for people who are very slender and have minimal fat in their body)

•the masseter—a muscle in the jaw— is the strongest muscle in the human body

•the average human's muscular system makes up 40% of their body weight

•the human body has over 600 muscles

•the muscles that work the most are the muscles that control your eye movements

•the human heart beats on average about 100,000 times a day

•on average, a woman's heart beats eight beats faster than a man's, because their bodies are usually relatively smaller and need to pump faster to deliver more blood around the body faster

•laughter is actually fantastic for your heart, as your heart doesn't need to work as hard to pump blood when you're laughing

This is inspired by veins and arteries🩸🧬

To me they're one of the most fascinating parts of the human body, shout out to the cardiovascular system, gotta be one of my favorite bodily functions‼️‼️🗣🗣
