The circulatory system includes the heart and all of the tubes connected to it. These tubes are collectively known as blood vessels.
No the heart does not make blood- the blood is made by the bone marrow.
Arteries- carry blood away from the heart. (I like to think Arteries Away.)Veins- carry blood to the heart.Capillaries- connect veins and arteries.Arteries are the tubes or vessles which carry the blood away from the heart once the blood has been oxygenated by the lungs. When it leaves the heart, it will begin the systematic circut, where the arteries get smaller and smaller, and become capillaries. Capillaries are smaller extensions of arteries and veins, supplying blood tho the bodies extremities. When the arteries deposit the oxygen and other nutrients through the capillaries, the blood then moves to the veins, which will carry the blood back to the heart. The veins are made from all the capillary branches moving back to gether. Veins have lower pressure than arteries, and also carry the deoxygenated "blue" or dark red blood, which will turn back to bright red once the blood is replenished in the heart, where the process starts again. So, * Arteries are the thick tubes carrying oxygenated blood from the heart to the extremities and organs, * Capillaries are the fine branches of arteries or veins which supply blood to the bodies extremities, * and veins are the thinner tubes carrying the deoxygenated blood back to the heart In other words:Arteries: carry rich blood from the heartVeins: carry poor blood to the heart
They are made up mostly of proteins called fibroin!Normally a spider has three pairs of spinners, but there are spiders with just one pair or as many as four pairs. Like the glands, every spinner has it own function. There are small tubes in the spinners which are connected to the glands. The number of tubes varies between 2 and 50,000. So, the gland'sconnected to the spinner and the spinner's connected to the small tubes. The head bone's connected to the neck bone. The neck bone's connected to the shoulder bone.
If you are asking where blood cells are "made," they are made in bone marrow.
The circulatory system.
cardiovascular system
Some organs that are made up from the circulatory system would be the heart, blood, and blood vesselsThe circulatory system is made up of the heart, Blood vessels, and blood.Heart, blood, veins, and arteriesThe heart and ALL the blood vessels.
Generally speaking, the heart is mostly made of muscle tissue and blood vessels.
Cardio vascular system is made up of the heart and the blood vessels.
Heart, lungs and blood
No, they are not. they are created it the bone marrow.
Well,circulatory system is made up of BLOOD and heart.
