no, pulmonary arteries do not carry oxygen rich blood?
Answer:
No, two arteries carry blood with low levels of oxygen:
Yes. When ever the arteries take oxygen rich blood to your muscles, the muscles take the oxygen out to use it to create energy. The oxygen deficient blood is taking back to the heart through the veins, then taken back to the lungs to extract oxygen again
Although it is an arguable topic whether blood is ever truly blue at one point or not, we'll just go along with the common lesson that "blue blood" is blood that is not oxygen-rich. This blue blood is carried in the pulmonary artery, where it is taken to the lungs in order to obtain oxygen, where it is then sent back to the heart, then sent to the rest of the body.
Arteries are thicker walled to hold the blood pressure of the heart pushing blood into them away from the heart. The thickness is from oxygen rich blood within them. Veins have no oxygen in the blood so that they must be fed oxygen with what ever red blood surrounds them. The blood pushed away from the heart thru an artery will flow faster than the blood drawn back to the heart, returning to the heart in a vein. (Simple fact blowing has more power than sucking.) This is why a banding around a limb usually fills with blood because the heart pressure pushes the blood through /past the banding but the draw from the heart isnt powerful enough to bring the blood back with the tight cord around your limb. Blood flows faster in the arteries because not only is their more muscle tissue than in a vein but arteries are thicker.
They can be what ever you want them to be!
Well An Ateriey Is A Blood Vessel Isn't It, & they Carry Blood, Now If You Have Ever Cut Yourself Then You Will Se Red Blood Because It Is Oxedised Blood, THe Same Stuff That Ateries Carrry. (Although Veins Carry Deoxodised Blood, The Oxegen In The Atmosphere Oxedises It) so Ateries Are Coloured By The Blood & Are Therefore Red.
yes the blood pressure in major arteries in the leg is greater than the blood pressure in arteries in neck during orbiting in an orbiting space station.
Blood goes threw EVER organ!!!!
no
the oxygen on a mountain is thinner than on the ground.
They did have a nucleus . When they are formed in the bone-marrow, they contain a nucleus, but when the become mature it is replaced by haemoglobin in order to carry more oxygen. By- Pranjal Prasoon
Arteries have no valves to prevent the blood from flowing backwards, but it is unnecessary when the heart keeps pumping. The blood pressure is highest when the blood is leaving the heart chamber into arteries -- the heart pumping keeps blood going one-way in the arteries.
The circulatory system play a key role in providing the body with the oxygen needed by cells. The circulating blood carries the oxygen replenished red cells through the arteries to all parts of the body.
