Your instructor asks you to write a paragraph discussing how the mouth, stomach, and small intestines work together to process food items and provide nutrients to the body. Which level of biological organization are you studying?

Organ system

Explanation:

An organ system is a group of organs that work together to perform one or more functions.

THE ORGAN SYSTEM.

The organ system explains how the mouth, stomach, and small intestines work together to process food items and provide nutrients to the body.

The mouth, the stomach and the small intestine are organs that makes up the digestive system.

The digestive is composed of functional related digestive organs that specializes on processing food items and provide nutrients to the body.

The organ system is a group of organs that work together to perform one or more functions. Each does a particular job in the body, and is made up of certain tissues. The 11 organ systems of the body are the integumentary, muscular, skeletal, nervous, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive and digestive. Although each of your 11 organ systems has a unique function, each organ system also depends, directly or indirectly, on all the others.

One of the most important functions of organ systems is to provide cells with oxygen and nutrients and to remove toxic waste products such as carbon dioxide. A number of organ systems, including the cardiovascular, digestive and respiratory systems, work together to do this.

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
