Which organ passes oxygen to blood?
The alveoli and capillaries in the lungs pass oxygen to the blood. Both have very thin walls, which allow the oxygen to pass from the alveoli to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.
What is going to happen if you have a heart failure?
This is caused due to a clot in the blood capillaries. This may lead to blood capillaries being killed which in turn causes a heart attack.
What do veins arteries and capillaries do?
Arteries take blood from the heart to the cells of the body. Capillaries take the blood to the individual cells to give them food and oxygen. They then take Carbon Dioxide and waste away from the cells. Veins then take blood from the capillaries back to the heart. The Heart then sends blood through another artery to the lungs. It goes through different capillaries to get rid of Carbon Dioxide and pick up Oxygen. Then it goes through another vein back to the heart. From the heart, it goes back to the starting point.During the process, some of the blood going to the cells of the body goes through the kidneys to get rid of wastes. Some goes through the liver to get rid of different wastes and to pick up food from the intestines. Some goes to muscles. Some goes to the brain. Some feeds the heart so it can pump blood.veins,artery,capillaries.
Do capillaries constrict?
When the body is going through inflammation, yes.
Why do the capillaries have holes?
So it carries blood in the body. If it has no holes how is it going to carry the blood with oxygen, CO2 and nutrients to the cells in your body?
What prevent the blood from going in the wrong direction in the heart?
valves
How does the blood run through the body?
Blood is pumped by the heart through arteries to deliver oxygen and nutrients to cells. It then flows through capillaries where gas exchange occurs, before returning to the heart through veins. This continuous circulation process supplies the body's tissues with vital substances and removes waste products.
What were does the nutrients go to after going through villi?
Villi are finger-like projections on the lining of the small intestine. After digestion is finished off, the nutrients and digested food goes to the villi, then from the villi to blood capillaries. Blood capillaries are small blood vessels that contain tiny holes through with tissue fluid leaks out. Then, the nutrients go from the blood capillaries to the tissue fluid. The tissue fluid is mainly water, it surrounds the tissues in our body and it forms a continuous link between the blood plasma (liquid part of the blood that helps the blood to circulate) and the cells. After going to the tissue fluid, the nutrients go to the blood plasma and then to the cells where it is used up (oxygen and chemicals from our food is separated from waste materials and carbon dioxide) Arteries carry oxygen from the blood cells to the body cells and veins carry carbon dioxide. After going to the cells, the nutrients go to the tissues. Hope this helped. I was also confused first but then my teacher explained it to me. :)
How does the circulatory system circulate nutrients?
Most nutrients are just dissolved in the plasma of the blood. They are transported to the cells when the heart pumps the blood through arteries, arterioles and capillaries. Nutrients diffuse through the walls of capillaries and enter cells.
Why you breath faster when you are frighten?
because the brain thinks youre panicking, and when you panick, you need more blood going through your system. so then the brain tells the heart to beat faster to get alot more blood flowing.
What is another example of diffusion other than osmosis?
The transfer of oxygen from the alveoli into the capillaries in the lungs, and the transfer of carbon dioxide from the capillaries into the alveoli (i.e. breathing in, and the oxygen going into the blood, and carbon dioxide going into the lungs to be expelled when we breathe out).
Do you arteries have Thick Rough inner walls?
Arteries have thick muscular walls to push your blood and spread out the pulse so it lowers its pressure. Your blood pressure is quite high when it leaves your heart and it comes in pulses. When it finishes going through your arteries and into your capillaries, your body wants it to go slow and be gentle. The muscles in your arteries change it to a smoother flow as they push it along.
