Humans break down food into component molecule.Digestion is necessary because the smaller molecule can be absorbed and utilized by the body to build structures and promote vital functions.Humans get vitamins and minerals from food, as well as macromolecules.If you like what you see, you might want to take a course in biology.
Step 1: Start at the mouth
The mouth is where the system starts.You pass food and drink from your mouth to the rest of your body.The mouth is involved in mechanical and chemical digestion of food.
Step 2: Food goes to the stomach.
The mouth and stomach are connected by a long tube.The food travels down the stomach until it reaches the stomach.The food is put in the stomach with hydrochloric acid to break it down.
Step 3: The endocrine system helps in digestion.
The hormones are produced by the endocrine system.The pancreas aids in digestion.The body can break down proteins and regulate blood sugar with the help of the pancreas.
Step 4: Know where the most vitamins are absorbed.
The majority of vitamins and minerals are absorbed in the small gut.There are three parts to this organ: the duodenum, the jejunum and the ileum.The purpose of each section is unique.In the duodenum, food and juices are broken down further for absorption.The jejunum is where most of the absorption of vitamins takes place.The large and small intestine are connected by the ileum.The last part of the food's nutrition is absorbed by it.
Step 5: How your colon absorbs water is explained.
After the food mass has been absorbed by your body, the remaining waste is saturated with water.The body can reuse this water.The colon is where the absorption of water happens.This process helps form a solid stool that your body can easily eliminate as waste.
Step 6: How waste leaves the body is something to think about.
A lot of waste in your body can be toxic.Your body has to excrete the waste left behind after you have eaten.When it reaches the anus, waste is moved along the length of the long intestine.The anus allows waste to leave the body.The anus is very small.It is usually less than an inch long.
Step 7: Understand how food is divided.
The first part of the digestion process takes place in the mouth.Your teeth grind down food into smaller pieces.The smaller pieces give stomach acid more surface area to react to.
Step 8: Understand how enzymes are used to break down large molecules.
The chemical breakdown of food begins in the mouth.Your saliva contains enzymes that break down food.The food has more enzymes in it's stomach and duodenum when you swallow it.Break down complex carbohydrates into simpler ones and break fats into simple fats are some of the most common uses for enzymes.
Step 9: Look at the absorption of vitamins and minerals.
The rest of your body needs vitamins and minerals.They are carried to the cells of the body in the bloodstream.The jejunum is the second part of the small intestine.The ileum is the third chamber of the small intestine.A very small amount of vitamins and minerals can be absorbed in the colon.
Step 10: You should study the absorption of water.
The leftover food mass has to be prepared for elimination.The first thing to do is solidify the mass.The colon forms solid feces when it absorbs water from the food mass.This helps to keep your body hydrated.
Step 11: Understand how the waste is eliminated.
Solid feces must exit the body after being formed in the colon.The waste moves the length of the colon.Your body expels feces at the anus.
Step 12: You should read ahead of time.
A lot of information is covered in a short time.You can easily fall behind if you aren't prepared.Before each class, set aside time to read the upcoming chapters.Bring your notes with you to class.
Step 13: diagrams to make
Many structures in the body have names that are hard to remember.One way to keep track of different structures and systems is to create diagrams or sketches of them.The diagrams don't have to be drawn perfectly, but you should make notes about the picture and label all parts.
Step 14: Class discussions are a good place to start.
Some people can listen to an instructor give a lecture and retain most of the information presented.Most people struggle with this.You should join any class discussions after taking class notes.It will help solidify the information in your brain.If you don't understand something, ask questions.Answer questions from your instructor.When appropriate, give an argument to support your answer.
Step 15: Pay attention to lab classes.
You will be able to relate the information you learn in class to real organisms.Pick a lab partner that is serious about doing well instead of messing with a friend.Make sure that you understand the entire lab by splitting the work evenly.
