What does blood carry - and where does the exchange of substances take place?
Blood carries oxygen, nutrients, hormones, and waste products. The exchange of substances between blood and body tissues occurs in the capillaries, which are tiny blood vessels with thin walls that allow for the transfer of molecules. Oxygen and nutrients are delivered to tissues, while waste products are picked up and taken away by the blood for disposal.
If the partial pressure of CO2 at sea level is approximately 0.23 mm Hg how does this influence gas exchange in terrestrial animals?
A lower partial pressure of CO2 at sea level can facilitate the diffusion of CO2 from tissues to blood. This promotes efficient removal of CO2 during gas exchange in terrestrial animals, ensuring effective respiration and transportation of gases in the body.
How carbon dioxide transported from body to the alveolus?
Carbon dioxide (CO2) is transported from the body's tissues to the alveoli primarily through three mechanisms: dissolved in plasma, bound to hemoglobin as carbamino compounds, and as bicarbonate ions (HCO3-) in the blood. In the tissues, CO2 diffuses into red blood cells, where it is converted to bicarbonate and transported in the plasma. Once the blood reaches the lungs, bicarbonate is converted back to CO2, which then diffuses into the alveoli. Finally, CO2 is expelled from the body during exhalation.
Why is there a higher percentage of CO2 in the air exhaled than inhaled?
During respiration, the body takes in oxygen from the air and releases carbon dioxide as a waste product. This results in a higher percentage of carbon dioxide in the exhaled air compared to inhaled air.
What happens too carbon dioxide that is in the blood?
Carbon dioxide (CO2) in the blood is primarily transported in three forms: dissolved in plasma, bound to hemoglobin, and as bicarbonate ions (HCO3-). When CO2 enters the bloodstream from tissues, it diffuses into red blood cells, where it is converted to bicarbonate for easier transport. This conversion helps to regulate blood pH and facilitates the removal of CO2 from the body through the lungs during exhalation. Ultimately, CO2 is expelled from the body when we breathe out.
Which type of blood vessels is directly involved in the exchange between blood and tissues?
Capillaries are very small and only one cell thick to allow O2/CO2 exchange. Nutrients and wastes are also exchanged.
Place where blood changes from low CO2 to high CO2?
The blood changes from low CO2 to high CO2 in the tissues where oxygen is delivered and CO2 is produced as a byproduct of cellular metabolism.
Why would you die if you do not breathe?
If you do not breathe the blood in your veins and arteries can not flow. The exchange of CO2 and oxygenated blood can not mix and exchange in the heart. The gas from CO2 will suffocate you and you will die.
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.

What process is when O2 and CO2 pass from the aveoli into the blood system?
The process is called gas exchange. Oxygen diffuses from the alveoli in the lungs into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
What do blood tissues carry?
Hormones,O2,CO2,Digestive products,excretory products
How wiil you describe the sequence of oxygen carbon dioxide and blood flow?
Oxygen is inhaled through the lungs and enters the bloodstream where it binds to hemoglobin in red blood cells. The oxygen-rich blood is then pumped by the heart to deliver oxygen to tissues throughout the body. Carbon dioxide produced by cells is carried in the blood back to the lungs, where it is exhaled. This cycle of gas exchange between the lungs and bloodstream maintains the balance of oxygen and carbon dioxide in the body.
What is a functions of alveoli in speech organ?
it help in the exchange of o2 in blood capillary and co2 from blood capillary into alveolus
What do a frogs lungs do?
The lungs are an exchange point where CO2 leaves and O2 enters the blood
Where does the blood go after it was pump to the body?
it will go back to the lungs carrying CO2 to exchange with O2
