What is the path Travelled by inhaled air?

When you inhale through your nose or mouth, air travels down the pharynx (back of the throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into 2 air passages called bronchial tubes.

What is the pathway of air into the body?

Air enters your body through your nose or mouth. Air then travels down the throat through the larynx and trachea. Air goes into the lungs through tubes called main-stem bronchi.

What is the pathway of oxygen in the breathing system?

Gas exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.

Which is the correct direction of blood flow?

The right and left sides of the heart work together Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. The pulmonary vein empties oxygen-rich blood, from the lungs into the left atrium.

How blood flows in the heart step by step?

Blood flows through your heart and lungs in four steps:

  1. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.
  2. The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.

How does the respiratory and circulatory system together?

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

Do respiratory and circulatory system work together during his fight if yes why do they need to do so?

Yes they work together. The body needs oxygen so blood comes into the heart. The heart then pumps the blood (deoxygenated) into the lungs where it receives oxygen. The heart then pumps the blood (oxygenated) to the body to be distributed to the cells and the cycle repeats.

What will happen if the respiratory and circulatory stop working together?

Answer: Oxygenated blood is brought to organs and tissues via the arteries, while veins bring deoxygenated blood back to the heart to be replenished. The point is, without the respiratory system your blood would be useless.

Which side of the heart pumps blood to the lungs?

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.

What are the similarities and differences of right and left ventricles?

Left and right ventricle collectively make the apex of the heart. Since the wall of the left ventricle is thicker than that of the right ventricle, the left ventricle pumps blood with high pressure. The main difference between the right and the left ventricle is the pressure of the blood pumped by each ventricle.

What are the similarities and differences between atria and ventricles?

Atrium Ventricle
Form the upper chambers Form the lower chambers
Two types- Right atrium and left atrium Two types- Right ventricle and left ventricle
Consists of thin wall Consists of thick wall
Collects blood and supply it to the ventricles Push blood throughout the body
