Homeostasis
--
Homeostasis in the digestive system
The process of digestion seems simple: Matter moves into the body and continues down a beltlike chain of organs that break it down completely before it leaves the body. Yet the maintenance of such a system is complex and relies on a balance of pH and helpful bacteria to maintain homeostasis. Saliva in the mouth is the starting point of digestion. The stomach, on the other hand, needs to be highly acidic to jump-start the breakdown process as well as act as a defense for the body against any harmful bacteria. To balance things out on the basic side, it is important that the small intestine has a high pH,

How respiratory system relates to homeostasis
In order to maintain homeostasis in the human body, oxygen needs to be delivered all throughout it. This is done through the diffusion of oxygen to the blood. The only way that the oxygen can get to the blood is from the use of the respiratory system. If the Respiratory system didn't work, or didn't deliver oxygen to the body, the rest of the systems would no longer function.
THE FOOD WE EAT πππ©π°
HOW CAN JUNK FOOD HURT US?
Eating junk food and fast food can hurt your body a lot.
Some ways that it can hurt you is it can cause obesity, high cholesterol, and more.
It can cause obesity because the fats in junk food and fast food.
It can cause high cholesterol because Junk foods such as donuts, boxed baked treats, processed foods and restaurant-fried foods contain trans fats. These fats have been linked to serious health problems. For instance, they are known to increase your levels of βbadβ cholesterol and decrease your levels of βgood cholesterol,β which can boost your chances of having heart disease, according to the Harvard School of Public Health.
