How many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!​
NISA [10]

Answer:

There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.

Explanation:

To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.

First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.

Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.

Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

It can lead to insulin resistance which increases the risk for type 2 diabetes. It can also lead to other chronic conditions like heart disease and stroke. Hence, its increased amount is not good for the body. It can be decreased by proper diet, exercise and decreasing stress.
