What is the pathway of oxygen gas molecules from an alveolus of the lung to the the right atrium of the heart and where are the areas of the gas exchange?

Oxygen is transfered into the blood at alveoli. Oxygen travels along the pulmonary vein into the left ventricle of the heart. It then travels along the aorta to the body tissues, gathering impure blood (CO2) along the way. Travels back to the heart via the Vena Cava and all impure blood is emptied into the right atrium of the heart, before it travels back to the lungs via the pulmonary artery.

atrium----> bicuspid (mitral) valve----> left ventricle----> aortic semilunar valve----> aorta----> systemic arteries-----> capillary beds of
tissues-----> systemic veins-----> superior or inferior vena cava-----> right atrium----->Tricuspid Valve-----> Right Ventricle.

What is the route of air from the external nares to alveolus?
Nostrils → Nasal Cavity → Pharynx → Larynx → Trachea → Main Bronchus → Lobar Bronchiole → Segmental Bronchus → Bronchiole → Terminal Bronchiole → Respiratory Bronchiole → Alveolar Duct → Atrium → Alveolus
What is one pathway in the flow of blood from the left index finger to the right atrium of the heart?
superficial digital veins to radial or ulnar vein to brachial vein to subclavian to superior vena cava into the right atrium
The pathway of oxygenated blood and deoxygenated blood through the heart?
Pulmonary vein, left atrium, left ventricle, aorta, arteries ,then to the capillaries
Where is the blood going to when it leaves the right side of the heart?
The pathway of a red blood cell from the right atrium and back. (1) right atrium -> (2) right AV valve -> (3) right ventricle -> (4) pulmonary valve -> (5) pulmonary trunk -> (6) pulmonary arteries -> (7) lungs, for exchange of gases (not shown) -> (8) pulmonary veins -> (9) left atrium -> (10) left AV valve -> (11) left ventricle -> (12) aortic valve -> (13) aorta -> (14) other systemic vessels -> (15) inferior and superior venae cavae -> (16) back to the right atrium The pathway from 5 to 8 is the pulmonary circuit. The pathway from 13 to 15 is the systemic circuit.
Pathway of blood cell through the circulatory system?
Right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary arteries > lungs > pulmonary veins > left atrium > bicuspid valve > left ventricle > aortic semilunar valve > aorta > arteries > arterioles > capillaries > venues > veins > superior/inferior vena cava > right atrium (again)
How does the gaseous exchange take place in cockroach?
Cockroaches have spiracles on the underside of their abdomen which draw in air which is then distributed to the the small adjacent chamber called the atrium. Stigmata bears limit the entry of dust into the tracheal system. The air then moves out of the atrium to the connecting trachea which carry the air directly to the cells fro gas exchange to occur
What is the pathway that blood takes through the body starting from the right atrium?
It helps to think of the right atrium as the ending point for the flow of blood; however, to answer you questions blood goes throughout the body from the right atrium as follows: right ventricle, left and right pulmonary arteries, lungs, air sacs within the lungs, left and right pulmonary veins, left atrium, left ventricle, aorta, to the upper and lower body, superior vena cave from upper body, inferior vena cave from lower body, back to the right atrium where the cycle starts again.
How does the size of the right atrium compare to the left atrium?
the size of the right atrium is smaller that the left atrium.
Where does the blood go after the exchange of carbon dioxide and oxygen?
Blood flows from the venous system to the right atrium of the heart to the right ventricle of the heart through the pulmonary arteries, to the lungs (where the CO2/O2 exchange is done) through the pulmonary veins, and back to the left atrium of the heart, to the left ventricle of the heart, and out through the aorta and to the rest of the body. It then returns through the veins and repeats the process.
How does the oxygen in the alveoli get to the body cells?
Oxygen in the alveoli is picked up by hemoglobin in erythrocytes (red blood cells) in the capillaries of an alveolus. The erythrocytes then travel back to the heart through the pulmonary vein and gets pumped to the rest of the body through the left atrium, left ventricle, and the aorta.
How is oxygenated blood enters the left atrium and flows into the left ventricles?
Through the gaseous exchange at alveolar level of lungs,deoxygenated blood get oxygenated in the lungs. Two left pulmonay arteries from left lung, similarly two right pulmonary arteris from right lung opens into the left atrium. Once left atrium gets filled, then it contracts. Through Mitral or Bicuspid Valve Oxygenated blood enters into the left ventricle from right atrium.
Does the atrium have depxgyenated blood?
well you have two atria the right atrium and left atrium but i think the right atrium has deoxygenated blood and the left atrium has oxygenated blood.
