What else can I help you with?
Are capillaries part of the lung?
Yes, capillaries form a network around the alveoli. It is through the alveolar walls and into the capillaries that oxygen enters the blood stream. Carbon dioxide leaves the blood by the reverse route.
How does oxygen travel in humans?
On a very basic level, it is absorbed through capillaries in the lungs into red blood cells in the the blood stream.
Why substances enter and leave the blood stream through the walls and capilliaries amd not arteries and veins?
Oxegen and Carbon dioxide
What is the network of vessels that returns fluid to the blood stream?
arteries
Why do capillaries have such thin walls?
Capillaries have thin walls to optimise the level of diffusion of oxygen and other nutrients in the blood stream to the surrounding cells.
What are the organs of the pulmonary system where gas exchange occurs?
Gasses are exchanged mostly through the cells
Where does blood and fluid exchange occur?
The blood enters the capillaries in single file ( capillaries have very small diameter so blood flow through them as in single line) there by diffusion the food passes towards the cell and waste from the blood enter the blood stream
What is the function of the heart in detail?
the vein and arteries help the blood go in, through, and out the heart............. I hope this answers your question... even though I know ur gonna take this answer and use it on your homework.
Which group of fats are absorbed pass through the intestinal cells and diffuse into capillaries and thus directly into the blood stream?
Water-soluble glycerol and short and medium chain fatty acids.
Where does the blood get the oxygen and digested food that it delivers to the different parts of the body?
From what I remember of secondary eduation i think the nutrients and oxygen from the food turn into enzymes in the intestines and them they are absorbed through the wall of the intestines and into the bloodstream. Hope I helpd! =)
Where is oxygen absorbed in the blood stream?
Oxygen is absorbed in the blood stream primarily in the lungs through the process of diffusion. When we breathe in, oxygen from the air enters the lungs and diffuses across the alveoli into the capillaries, where it binds to hemoglobin in red blood cells and is transported throughout the body.
What are the types of blood vessel and what do they do?
There are 3 basic types of blood vessels: arteries, veins, and capillaries. Arteries carry blood away from the heart (remember "a" for away) and to the other organs and tissues in the body. Veins carry blood back to the heart. Capillaries serve as the "transfer" vessels. They help transfer the contents of the blood stream to the major organs and tissues that need oxygenation, and draw waste products from the target tissues back into the blood stream. Since arteries carry blood away from the heart and to the rest of the body, they typically contain oxygen-rich blood. Veins typically contain oxygen-poor blood. The one exception to this rule is the pulmonary artery and pulmonary vein. The pulmonary artery carries oxygen-poor blood from the heart to the lungs to obtain oxygen, and the pulmonary vein then returns the newly oxygenated blood to the heart.
