I’ve heard that digestive enzymes are made out of amino acids but aren’t they also made out of other nutrients such as vitamins or minerals? -iron maybe? Please clarify.

Explain how the circulatory system transports nutrients and oxygen to cells and removes cell wastes.
Describe how the kidneys and the liver are closely associated with the circulatory system as the perform the excretory function of removing waste from the blood. Recognize the kidneys remove nitrogenous wastes, and the live removes many toxic compunds from blood.

The primary threat to life when the circulatory system is damaged is:

a. lack of oxygen to vital tissues
b. loss of blood and nutrients
c. irregular heartbeat
d. broken blood vessels

I heard you could have years of undigested stuff in your colon that sticks to the walls and prevents you from absorbing nutrients in the foods you eat now.

Describe how the digestive system converts carbohydrates, proteins, and fats in dairy and soy milk into nutrients that can be used by the cells.

For science we have to bring in food and build an artificial digestive system to break it down. Thing is, we have to keep the nutrients the food provides. Any suggestions?

I was thinking about what i learned in science today, and have a question. please only serious answers only and only if you know its true, idont want to learn false info.
How do the respiratory system and circulatory system work together to provide nutrients to tissues and remove waste from tissues. this isnt homework or anything, it is just a problem that popped into my head. thanks for your time!

List the functions that your circulatory system, made up of your heart, blood vessels, and blood, does to help keep you alive. Explain how oxygen and nutrients get delivered to the body’s cells….

Absorption: How does the digestive system deliver nutrients to blood?

Discuss some of the adaptations in the digestive systems of animals

Besides the main role of circulating blood, ridding the body of wastes, and circulating nutrients throughout the body, what are some secondary functions of the circulatory system?

Digestive System?
1-what is the digestive liquid that is produced in the mouth?
2-ehat is the function of the epiglottis?
3-what is the muscular tube that connects the mouth and stomech?
4-what is the name of the wavelike process that pushes food through the esophagus and the rest of the digestive system?
5-how do the muscles in the stomech aid in mechanical digestion?
6-in which organ are simple nutrients absorbed into the bloodstream?
7-whare is the villi located?
8-what organ produced bile?
9-what organ stores bile?
10- what is the function of the pancreas in digestive?
11-describe the function of the large intestine.
12-fiber is a carbohydrates that cannot be broken down in digestive.why do you think it is necessary for the proper functioning of the digestive system?

Thank you
