Idk a lot about this stuff but I wanted to help cuz I can tell it’s hard. I found this online and think it might help you out with figuring out how you need to write it.

Processing Nutrients
Maintaining homeostasis keeps the internal environment in the body functioning properly. Many organ systems work together and maintain energy homeostasis.
The body gets most of its energy from carbohydrates. Lipids and proteins also provide energy. The food you eat is broken down by chemical and mechanical digestion.
Chemical digestion occurs when enzymes in saliva
and acid in your stomach break down food. Mechanical digestion happens when you chew your food. The digestive system, the circulatory system, and the muscular system work together and process and obtain nutrients from food. The skeletal system, the endocrine system, and the lymphatic system also work with the digestive system and process those nutrients.
Muscles and Digestion
Food enters the body through the digestive system. There it is broken down into nutrients that can be absorbed into the body. However, the muscular system is needed to get food through the digestive system. Muscles that surround the stomach contract and move food to the small intestine. These contractions are called peristalsis (per uh STAHL sus).
Muscles help the jaw move when you chew. They help you swallow. Muscles also surround the esophagus, the stomach, the small intestine, and the large intestine. These muscles help move food through the digestive system.
Circulation and Digestion
The small intestine has two important jobs. It breaks down food and absorbs nutrients. The muscular system and the circulatory system work with the small intestine.
The muscular system helps the small intestine break down food. The circulatory system works with the small intestine and gets nutrients to the rest of the body.
Nutrients are absorbed by small, fingerlike projections called villi (VIH li; singular, villus) in the small intestine.
The villi have blood vessels inside them, which are part of the circulatory system. Nutrients enter these blood vessels and are then transported to the rest of the body. The muscular system also surrounds the blood vessels and helps blood and nutrients move through the body. The figure on the next page shows a close look at one villus and how the digestive system and the circulatory system work together.
Processing Oxygen and Wastes
The systems of the human body must work together for the body to function properly. For example, humans require oxygen to survive. Your lungs take in oxygen and release carbon dioxide. The cells in your body use oxygen to help process the energy in nutrients into energy that cells can use. Oxygen helps the body obtain energy from nutrients by performing cellular respiration. As discussed next, various organ systems work together and help the body take in oxygen and move it through the body.
Eliminating Wastes
The excretory system works with several other organ systems and eliminates wastes. Recall that the body processes food, oxygen, and liquids.
Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum.
The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body. Oxygen is used in all organs of the body. The CO2 produced by cells in the body enters capillaries and is transported to the lungs, where it is exhaled. These three systems work together and maintain oxygen homeostasis by making sure that CO2 is removed.
The excretory system also maintains fluid homeostasis. Liquid waste travels through the circulatory system to the kidneys, as shown in the figure on the next page. The kidneys make urine. Liquid waste also travels to the skin where fluid is released during sweating.
