How does the kidney and lungs work together?

Answer 1

Your respiratory system includes the mouth, trachea, main bronchus, bronchi, lungs, bronchioles, and aveoli or air sacs within the lungs. The diaphragm and muscles of respiration are also involved, as is the brain and the heart. Of these, the only ones considered "organs" are the lungs, heart, and brain.

The process of respiration is partly involuntary, and partly voluntary. In healthy persons, the brain stem and brain react to increasing levels of carbon dioxide (CO2), forcing a human to take a breath. This is a feedback system. Note: In chronic lung diseases such as emphysema, this feedback system is reversed: the person's brain becomes accustomed to higher CO2 levels and can die if they are placed on too much oxygen (O2).

When breath is triggered, air is brought through the nose, mouth, or both. It is warmed in the nose, brought down the throat / trachea, and into the main brochus, which splits into the right bronchus and left broncus. In the lungs, it resembles an upside-down tree, with the main bronchus as a "trunk". The two bronchi further "branch" into the bronchioles, which end at the aveoli. There exchange of CO2 and O2 occurs.

At the same time, the de-oxygenated blood from all body areas has returned to the heart. It is sent through the arteries into the lungs, where the CO2 is "dropped off" to the aveloi. The aveoli "pick up" the fresh air containing oxygen, and transfers the O2 onto hemoglobin. Hemoglobin (Hbg) molecules are attached to every Red Blood Cell (RBC). The Hemoglobin (Hbg) on the RBC which are all part of normal blood is then carried back to the heart where it pumped out from the heart to the body and brain.

At the cellular level, blood carries nutrients and O2 to awaiting cells. The work done by the cells produce "by products" and chemical "waste" which is then exchanged between the blood and the cells. The blood now becomes known as venous blood or de-oxgenated blood, because it dropped off the oxygen and now conveys cellular waste including CO2.

The venous blood returns to the heart where it again is filtered through / by the lungs to get rid of CO2 and pick up O2. The brain has signaled the need for a new breath.... And the cycle begins once more.

Humans also have partial voluntary control over respirations. For example, you can take rapid or shallow breaths; or you can hold your breath for a time. But, the involuntary control overrides the voluntary control in healthy persons, and re-establishes a normal respiratory pattern

Answer 2

Our body has blood vessels, which are spread throughout the body like pipelines to a city. The heart on the right side pumps the blood to lungs, where the oxygen breathed in by us is taken up by red blood cells. This blood returns to left part of heart and is pumped to all blood vessels in body.

Body cells use oxygen from blood cells. This blood, which is depleted of oxygen, returns to the right side of the heart and is pumped to the lungs again. This process continues again and again in the cycle.

Total blood in a human is about 5 liters of blood. The heart pumps 5 liters of blood in one minute. So in a day, our heart pumps 7,200 liters of blood without stopping!

Answer 3

Since the heart moves the blood, and the lungs change the gas composition of blood, and the main function of blood is to move gases into and out of the cells ... they're both required.
