Why is there a higher percentage of CO2 in the air exhaled than inhaled?
The air we inhale comes from the athmosphere; the percentage of CO2 in the athmosphere is next to insignificant. The air we exhale comes from the cellular environment; cells give off CO2 as part of their metabolism, thus CO2 venous blood concentration is high
What does blood carry - and where does the exchange of substances take place?
blood carry gases like o2,co2...nd the exchange of substances take place in small intestine
What is the main function of blood?
The main function of blood is to supply oxygen,nutrients to the tissues,removal of waste such as CO2,urea and regulation of body temperature.
How oxygen is transported through the circulatory system?
Oxygen goes from the lungs to the tissues via the blood stream and CO2 goes back to the lungs via the blood stream
What do your red blood cells do?
They transport respiratory gases.They take O2 to cells and take CO2 from cells.
What process is when O2 and CO2 pass from the aveoli into the blood system?
External respiration. On the other hand, if the exchange occurs between the blood and tissues, then it's referred to as internal respiration.
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.
How wiil you describe the sequence of oxygen carbon dioxide and blood flow?
Blood flows in a circle from lungs to tissues and back. At the lungs O2 gets into the blood and CO2 gets out - at the tissues O2 leaves the blood and CO2 enters.
What gas diffuses from the tissues to the blood?
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
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 Contain hemoglobin and transports oxygen to the body tissues and removes CO2 from the body tissues?
The circulatory system ie blood.
What do blood tissues carry?
Hormones,O2,CO2,Digestive products,excretory products

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
What does blood carry - and where does the exchange of substances take place?
blood carry gases like o2,co2...nd the exchange of substances take place in small intestine
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
