What is the importance of respiration in humans?
The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
What is the most important thing about the respiratory system?
The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.

Can you live without lungs?
The lungs are key organs in the human body, responsible for bringing oxygen into the body and helping get rid of waste gases with every exhale. Though having both lungs is ideal, it is possible to live and function without one lung. Having one lung will still allow a person to live a relatively normal life.
How long can someone live without lungs?
In general, you need at least one lung to live. There is one case of a patient who had both lungs removed and was kept alive for 6 days on life support machines until a lung transplant was performed. This is not a routine procedure and one cannot live long without both lungs.
Is air conditioning bad for lungs?
Respiratory diseases The cold is one of the factors that trigger typical asthma symptoms such as coughing, wheezing, and shortness of breath. Additionally, prolonged exposure to air-conditioning can contribute to worsening asthma and to the development of lung infections resulting from this condition.
What is the role of the lungs in blood circulation Brainly?
Answer. Answer: The pulmonary system is responsible for providing fresh oxygen to the blood and removing carbon dioxide, according to the National Center for Biotechnology Information (NCBI). Oxygen-poor blood arrives from veins leading to the right atrium of the heart.
Is the heart between the lungs?
The heart is a strong and muscular, cone-shaped organ that is about the size of a fist. It pumps blood throughout the body and is located behind the breastbone between the lungs.
How does the lungs and heart work?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
How does a heart attack affect the lungs?
A damaged heart can’t pump blood as effectively from your lungs out to your body. Blood backs up, raising pressure in the veins inside your lungs. This pushes fluid into your air sacs. As liquid builds up, it gets harder to breathe.
