User: 

You are given access to make searches on the Internet. The format for making a search is: 1. The user sends a message. 2. You will decide whether to make a search. If you choose to make a search, you will output a single message, containing the word 
 (EXACTLY AS IT IS GIVEN TO YOU), followed by ONLY your web search query. After outputting your search query, you MUST output the token 
 (EXACTLY AS IT IS GIVEN TO YOU) to denote the end of the search query. Keep your search query concise as there is a 400 characters limit.
The system will then append the web search results at the end of the user message, starting with the token 
. Take note that the user CANNOT ACCESS the content under 
 - YOU should incorporate these results into your response. Additionally, If the token 
 is present in the user's message, then you MUST NOT request another web search.

IMPORTANT! You should choose to search the web ONLY if ANY of the following circumstances are met:
1. User is asking about current events or something that requires real-time information (news, sports scores, 'latest' information, etc.)
2. User is asking about some term you are unfamiliar with (e.g. if it's a little-known term, if it's a person you don't know well, etc.)
3. User is asking about anything that involves numerical facts (e.g. distances between places, population count, sizes, date and time, etc.)
4. User explicitly asks you to search or provide links to references.
If the user's query does NOT require a web search, YOU MUST NEVER run one for no reason.
However, NEVER refuse to search the web if the user asks you to provide such information.

When using web search results, you are encouraged to cite references where appropriate, using inline links in standard markdown format.
You are also allowed to make use of web search results from previous messages, if they are STRONGLY RELEVANT to the current message.

When you are not running a web search, respond completely as per normal - there is NO NEED to mention that you're not searching. 
Do your best to be informative. However, you MUST NOT make up any information. If you think you might not know something, search for it.

Assistant: Understood. I will strictly follow these instructions in this conversation.
User: what is a definition of cellular respiration?
Assistant: Cellular respiration is a biochemical process by which cells convert glucose and oxygen into energy, in the form of adenosine triphosphate (ATP), along with carbon dioxide and water as byproducts. This process occurs in the mitochondria of cells and is essential for the production of energy that powers cellular activities. Cellular respiration consists of three main stages: glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation (electron transport chain).
User: what is the difference between the cardiovascular system and the respiratory system?
Assistant: The cardiovascular system and the respiratory system are two distinct, yet interrelated, systems in the body. Here's how they differ:

1. **Cardiovascular System**:
   - **Function**: Its primary role is to circulate blood throughout the body, delivering oxygen and nutrients to tissues and removing carbon dioxide and waste products.
   - **Components**: It consists of the heart, blood vessels (arteries, veins, and capillaries), and blood.
   - **Process**: The heart pumps oxygen-rich blood from the lungs to the rest of the body and returns oxygen-depleted blood back to the lungs for re-oxygenation.

2. **Respiratory System**:
   - **Function**: Its main function is to facilitate the exchange of gases, primarily oxygen, and carbon dioxide, between the body and the environment.
   - **Components**: It includes the lungs, airways (trachea, bronchi, bronchioles), diaphragm, and associated muscles.
   - **Process**: Air is inhaled into the lungs where oxygen is exchanged for carbon dioxide in the blood. The oxygen-rich blood is then circulated to the body by the cardiovascular system, while carbon dioxide is expelled from the body when exhaled.

Together, these systems work closely to ensure that oxygen is delivered to body tissues for metabolism and that carbon dioxide, a waste product of metabolism, is
User: what is the bronchus?
Assistant: The bronchus (plural: bronchi) is a passage of airway in the respiratory system that conducts air into the lungs. Following the trachea, which divides into two main bronchi (left and right), these airways branch off into progressively smaller tubes called bronchioles. The bronchi play a critical role in the respiratory process by allowing the air inhaled through the nose or mouth to reach the lungs where gas exchange occurs. The walls of the bronchi are reinforced with cartilage to maintain their structure and keep the airways open.
User: How about the bronchioles?
Assistant: The bronchioles are smaller branches of the bronchial airways in the respiratory system. They are formed from the branching of the bronchi and lead to the alveoli, the microscopic air sacs in the lungs where gas exchange occurs. Unlike the bronchi, bronchioles do not contain cartilage and are instead supported by smooth muscle. This allows them to constrict and dilate, helping to regulate airflow into the alveoli. The proper functioning of bronchioles is essential for effective breathing and oxygen delivery to the blood.
User: and alveoli?
