[Hook: TiJay]
Digestive, endocrine, immune, lymphatic
End your body system, your crew don't want no static
Muscular, urinary, skeletal
We win the battle, capture your mental
Respiratory, nervous, you're nervous
Nervous, you're nervous
Nervous, you're nervous
[Verse 1: The Bishop]
The science knowledge is flowing out of me like a drug
And I'm never running out of energy mitocondria
And my flow is pretty nasty, it's catchy, it's flashy
And none of you wack rappers can't match me
My team is here to break down the human body systems
And diseases too because most of y'all have some symptoms
But I digress, the problem is most of you cats can't even digest
Digest, I eat my competition up
And all I know is I got them shaking like asma pump
[Verse 2: AJay]
Chewing your food while eating dinner
Down to the throat to the stomach and liver
It produces the bile, it's cleaning the system
The food goes down symptom by symptom
The food melts down on the gastric acid
Classic, it's on the stomach acid massive
Tactic, my bars are everlasting
Double two to the four, call me fantastic
Yeah, this is serious, I'm feeling delirious
Survival of the fittest, evolution
George, I'm curious
[Hook x2]
Stomach acid has a pH between 1.5 and 3.5. In comparison, vinegar has a pH around 3.0. Gastric acid will definitely dissolve your food, breaking down whatever you eat into vitamins, minerals, and other organic waste!

Bile is a yellow-brown liquid (see above) produced by the liver that facilitates digestion in vertebrae.
Mitochondria are an engine of sorts within a cell. They help generate cellular energy and trigger certain cell processes while controlling the cell cycle. WIth a workload like this, they seemingly never run out of energy.

The endocrine system is a series of glands throughout the body that secrete all the various types of hormones.

2 multiplied by 2 is equal to 4.

Also a slick reference to the comic book and movie, Fantastic Four.

The human digestive system is a complex series of organs and glands that processes food


This transition from a listing of body systems into a description of feeling, from nervous system to just describing someone as nervous, or anxious, captures the power of understanding the mechanisms underlying our feelings and experiences. Calling someone nervous with a reference to the nervous system gives it weight by calling to mind all the neurons whose activity produces the behavioral result.
The lymphatic system is part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph directionally towards the heart.

The immune system is a system of biological structures and processes within an organism that protects against disease
