The pizza that you ate for lunch is being digested. Summarize what happens to it in your stomach.

When you eat pizza, the initial mechanical breakdown occurs in your mouth, where your teeth chop it up and mix it with saliva. Once swallowed, the pizza enters your stomach, where it is churned and combined with digestive enzymes and gastric acid, facilitating the breakdown of its components. As digestion continues, enzymes from the liver and pancreas further break down fats and proteins. Eventually, waste materials are compacted in the intestines and removed from the body.

In your stomach, **: the pizza is churned, mixing it with digestive enzymes and gastric acid. This process helps break down the food further for absorption in the intestines. Options **B**, **C**, and **D** pertain to other stages of digestion, either occurring in different parts of the digestive system or prior to reaching the stomach.

How does the nervous system influence the respiratory system?

It controls muscle contraction.
It regulates blood pressure.
It regulates urine output.
It stimulates defense against pathogens.

The primary way the nervous system influences the respiratory system is through **it controls muscle contraction**. The nervous system provides signals to the diaphragm and other respiratory muscles to contract and relax, facilitating the process of breathing. This control allows for adjustments in breathing rate and depth in response to various physiological demands. The other options listed do not directly pertain to the regulation of the respiratory system.

How does the nervous system influence the respiratory system?

It controls muscle contraction.
It regulates blood pressure.
It regulates urine output.
It stimulates defense against pathogens.

The correct answer is **It controls muscle contraction**. The nervous system regulates the contraction of the diaphragm and other muscles involved in breathing, allowing for the control of respiratory rates and depth in response to the body’s needs. This coordination is essential for effective ventilation and gas exchange. The other options listed are not directly related to the influence of the nervous system on the respiratory system.

Which system comprises of skin, hair, and other parts of the outermost layer of the body?

endocrine system
lymphatic system
integumentary system
nervous system

The system that comprises skin, hair, and other parts of the outermost layer of the body is the **integumentary system**. This system serves to protect the body, regulate temperature, and provide sensory information.
