What is the pathway of the drop of blood from the time it picks up oxygen in the alveoli until it is used by a body cell?

The blood picks up oxygen from the alveoli into the Red Blood Cells (RBCs) In the pulmonary circulation, the circulation where blood is pumped by the right ventricle around the lungs. The capillar beds where this tansfer takes place anastomose (join) to form the only oxygenated veinules on the body, which in turn join to for the Pulmonary Artery. There are two pulmonary vein, one does to each lung. The pulmonary veins carry the blood carry the newly oxygenated blood into the left atrium of the heart. When the left atrium contranct the blood is pushed down into the left verticle, through the mitral (or bicuspid) valve. The left ventricle is the strongest part of the heart as it has to push the blood all around the body, including right to the top of the head. When it contracts it pushes the blood out through the Aortic Vavle and into the Aorta which strechec a little under the pressure. From here it is difficult to be entirely specific as there is not reference in the question as to what organ or tissue is to be supplied so I Shall have to be generic. From the aorta stem the major arteries, into one of which the blood now flows. From these arteries come smaller areteries that are more specifically aimed at certain parts. From these comes arterioles, form which comes more capillary beds. Within these cappilaries however the oxygen is removed from the blood instead of put into it. From here the blood takes route back to the heart to stard again.

How does the blood change carbon dioxide for oxygen?
Oxygen diffuses from the alveoli in the lungs into the blood by way of diffusion. The O2 passes across the thin cell membranes and is taken up in our capillaries by the haemoglobin in our red blood cells. Carbon dixide transfers in the opposite direction: from the blood plasma, across the cell membrane, and into the alveoli, where it is then exhaled.
What is a sack shaped respiratory organs where blood picks up oxygen?
You refer to the lungs.
How does the exchange of carbon dioxide for oxygen take place in the lungs?
The exchange of oxygen and carbon dioxide takes place in between the alveoli and capillaries. Oxygen moves through the cell membrane of the capillaries of the alveoli and then into the blood. Then oxygen is picked up by hemoglobin, and carried to all the body cells. At the same time, waste(carbon dioxide) leaves the body by exhaling --- @luvzbieber
What happens to the blood during pulmonary circulation?
When blood enters the pulmonary arteries, it is sent into the lungs' capillaries. Capillaries are only about one cell thick, so oxygen in the aveoli is able to diffuse into the bloodstream. Red blood cells contain hemoglobin, which has a high affinity for oxygen. Oxygen binds to the red blood cells and is delivered to cells in need of oxygen. In addition, the blood enters the lungs in the alveoli area and it releases CO2. After it releases the CO2, the erythrocytes in the blood bond with oxygens. The blood is then carried back to the heart.
Do the red blood cells pick up oxygen in the lungs?
Yes, they do. The haemoglobin in biconcave red blood cells picks up the oxygen at the lungs, and drops it off at a respiring cell.
How does the respiratory system supply the body with oxygen?
Hemoglobin (in the red blood cells) (devoid of oxygen) gets into the alveoli (little capillary filled air sacks) and picks up oxygen. Then the circulatory system transports the oxygen-rich blood around.
What happens to the blood as it flows through the capillaries in the lungs?
The CO2 or carbon dioxide is removed by the alveoli from the blood. The carbon dioxide is replaced with oxygen. The blood is then full of oxygen. Alveoli are tiny sacs in the lungs, surrounded by capillaries.
What picks up oxygen in the lungs?
Bronchi are in the lungs. Off the two bronchi branches are broncioles and off of those are alveoli which take in the oxygen
Where does blood pickup oxygen?
Blood picks up oxygen from the lungs.
Which substance in the blood picks up the oxygen?
Hemoglobin is the substance in the blood that picks up oxygen. Hemoglobin is found on red blood cells.
What tissue do both the heart and lungs rely on do their jobs for the body?
The heart and lungs rely heavily on blood, a liquid connective tissue, to carry out their function. The heart pumps the oxygen-containing blood throughout the body. The blood picks up oxygen at the alveoli of the lungs.
What passes between alveoli and capillaries?
Capillaries are tiny thin-walled blood vessels that connect the smallest arteries and veins and allow the exchange of nutrients and waste between the blood and tissues. Oxygen and carbon dioxide are exchanged between the circulatory and respiratory systems; oxygen diffuses from the lungs into the bloodstream and is transported by erythrocytes (red blood cells) throughout the body. Carbon dioxide diffuses out of the blood into the alveoli and goes the reverse direction through the respiratory system and out the nose.
What are the functions of alveoli?
Alveoli are tiny sacs in the lungs that perform gas exchange. That is the main process of respiration where the body gets rid of carbon dioxide and picks up oxygen which is used in metabolism. They have supply of oxygenated and de-oxygenated blood surrounding their surface giving them a high blood supply. They also have thin walls and a moist surface. This is all required for them to work correctly.
What substance in the blood picks up oxygen?
Erythrocytes
What does the heart deliver to our lungs?
Blood with no oxygen (the blood that flows to the heart picks up oxygen from the lungs).
Which two gases are exchanged in the aveoli?
At the aveoli, the blood transfers CO2 and the hemoglobin on red blood cells picks up 02.
How does oxygen that he breathes in with air get into his blood?
it goes to the lung and the blood picks it up there
