Why these pure substances come up into mixtures?
we will mix if the pure substance come up
Where do gases exchange?
The pathway of the circulatory system varies based on different species. The mammalian cardiovascular system begins with the pulmonary circuit. The right ventricle pumps blood to the lungs via the pulmonary arteries. As the blood flows through capillary beds in the lungs, it adds oxygen and subtracts carbon dioxide. Oxygen-rich blood comes from the lungs via the pulmonary veins to the left atrium of the heart. Next the oxygen-rich blood flows into the left ventricle as the ventricle opens and the atrium closes. The left ventricle pumps the oxygen-rich blood out of the body tissues through the systemic circuit. Blood leaves the left ventricle through the aorta, which passes blood to arteries leading throughout the body. The first branches from the aorta are the coronary arteries which provide blood that the heart muscle needs. Then come branches leading to capillary beds in the forelimbs. The aorta continues, supplying oxygen-rich blood to arteries leading to arterioles and capillary beds in the abdominal organs and legs. Inside the capillaries, oxygen and carbon dioxide diffuse along their concentration gradients with oxygen being moved from the blood to the tissues. Carbon dioxide produced by cellular respiration diffuses into the bloodstream. Capillaries join again, forming venules, which give blood to veins. Oxygen-poor blood from the head, neck, and forelimbs is guided into a large vein called the anterior vena cava. Another large vein called the posterior vena cava drains blood from the chest and back legs. The two venae cavae empty their blood into the right atrium and the oxygen-poor blood flows into the right ventricle.
What substances are used to make nylon fibers?
Substances used in making nylon fibers come from petroleum based chemicals or petrochemicals. Different chemical compounds are used to produce different fibers.
When you breath out where does the moisture come from?
it comes form your lungs when they mix oxgeyn with the blood the moisture is not blood
What common properties do some acids and bases have when they come into contact with solid substances?
Both can be corrosive, eating away at solids
In which blood vessels does the exchange of oxygen and food nutrients and waste materials from the blood take place?
Capillary.capillariesCapillaries.Blood flow moves from arteries, to arterioles, to capillaries, to venules, to veins, to the heart, and then back to arteries. Capillaries are where the exchange of oxygen and other materials happens.Capillaries
What is relationship of the alveoli to capillaries?
The alveoli branch from the bronchioles and are responsible for gas exchange with the pulmonary capillaries. They come in close contanct with the capillaries so the exchange of O2 and Co2 can occur rapidly and easily.
How does the blood come in contact with the muscle?
Via the capillaries, it doesn't actually come in contact with the muscles directly, but is contained by the capillaries which are just one cell thick. From these all the nutrient (i.e. Oxygen, glucose etc.) simply pass across the capillary walls by diffusion. The blood enters the capillaries from the arteries and exits in to the veins.
What would happen if you didnt have capillaries?
If we didn't have capillaries, we would die. This is because CAPILLARIES are the passageways between the arteries (carrying oxygen- rich blood AWAY from the heart) and the Veins (carrying oxygen- poor blood back INto the heart). Capillaries come in close contact with the body's organs. They exchange their oxygen- rich blood (provided by the arteries) with the organ's oxygen- poor blood (containing carbon dioxide). Thus, the body's organ supply of oxygen- rich blood is replenished. Then, the capillaries give their oxygen- poor blood (from the organs) to the Veins, which bring the blood back to the heart, so it can be filled with oxygen again. It's all a big cycle, and our capillaries play a big role in this cycle. The heart, blood, and blood vessels (arteries, veins, and CAPILLARIES) are all a part of the amazing Cardiovascular System! (Also known as Circulatory system) We really need those Capillaries !! So... What would happen, you ask? Well, the blood in the arteries an the blood in the veins would mix. That is very bad. Our body could not survive if oxygen-rich blood and oxygen- poor blood mixed. We have the capillaries to ensure they never interact!!
Is milk part of blood?
Not really. However, most of the nutrients that are found in milk come from the blood vessels and capillaries that run in the udder. Through the action and process of nutrient exchange from the cells in the udder and the capillaries, nutrients from the blood which are from the contents that the cow has eaten are deposited in the milk cells, then collected consecutively, from the alveoli, to cisterns and finally the glans cistern where milk is released into the teats and collected by the calf, the milk machine or the person hand-milking the cow.
How are the placenta and the umbilical cord related?
The umbilical cord is attached to the developing fetus at the navel, and it has two main blood vessels in it; the umbilical artery and the umbilical vein. These vessels form a network of capillaries at the placenta, which is the temporary organ on the wall of the mother's uterus which forms during pregnancy. In the placenta, the mother's blood vessels also narrow to capillaries. The baby's capillaries and the mother's capillaries come side by side, and in that way metabolic wastes diffuse from the baby's blood to the mother's blood so her body can excrete them, and the baby's blood picks up O2 and nutrients from the mother's blood. The umbilical cord is the connection between the baby and the mother, and the placenta is the area in a pregnant woman's uterus which is the site of exchange of various wastes and nutrients between mother and child. The baby's blood and the mother's blood, however, never directly mixes. Everything is accomplished via diffusion between the capillaries in the placenta.
What are the main blood vessels and what do they do?
The three main blood vessels are the arteries, veins, and the capilliaries.Arteries carry blood away from the heart. Blood from the arteries is under high pressure since it has just come from the heart. A cut in the artery may be fatal due to blood loss. However, it's thickness, elasticity, and location protect it from damage.Capillaries are extremely thin. Only a single file of red blood cells can pass through the capillaries. However, the actual exchange of substances in the body occurs in the capillaries.Capillaries join to form venules. These small vessel units form veins. Veins carry non-oxygenated blood to the heart.
What are tubes that carry blood around the body?
These tubes (along with the heart) are known as the circulatory system, and they come in three varieties: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are smaller diameter tubes connecting arteries and veins, through which blood interacts with tissues of the body.
Blood goes into lung alveoli?
Blood does not go into the alveoli, that would only result from a hemorrhage. Blood does come close to the alveolar sacs via small capillaries that are there to perform an action called gas exchange. This process occurs as a result of diffusion and releases the carbon dioxide in the red blood cells and is replaced by oxygen to be carried to the body tissues and used in tissue respiration.
How does gas exchange occur in the alveoli?
Gas is exchanged by diffusion. We have followed the path of the air and of the oxygen into the bloodstream. But breathing is a two-way street: we breathe in and then we breathe out. When we breathe in, or inhale, oxygen is removed from the air. Breathing also removes waste from the lungs and from our noses and mouths. How does this waste material get into the air that we breathe out, or exhale? The thin walls of the alveoli actually have two purposes. When we breathe in, oxygen passes through the walls of the alveoli and into the blood. Carbon dioxide and water vapor then travel the opposite direction. They are the main waste products that pass from the blood vessels (arteries) in the lungs, into the alveoli, through the windpipe and out the nose and mouth. In the alveoli, oxygen crosses over into the blood stream and carbon dioxide leaves the blood stream and enters the alveoli to be expelled through the lungs.
Left ventricle lead to fluid in the lungs?
Left ventricle pumps oxygenated blood out through aorta and to the rest of the body. The right ventricle will pump deoxygenated blood to the pulmonary artery to get oxygenated in the lungs. Then the oxygenated blood will come back down the pulmonary vein into the left atria, and then left ventricle. The blood never fills up the lungs, the gas exchange occurs within the capillaries in the lungs.
What are that's Carrie the blood around the body?
These tubes (along with the heart) are known as the circulatory system, and they come in three varieties: arteries, veins, and capillaries. Arteries carry blood away from the heart, veins carry blood back to the heart, and capillaries are smaller diameter tubes connecting arteries and veins, through which blood interacts with tissues of the body.
