A vein is a blood vessel that conducts blood toward the heart. Compared to arteries, veins are thin-walled vessels with large and irregular lumens.
<h3>Where are blood vessels found in your body?</h3>
- Blood is delivered to human tissues by arteries, which act as conduits or channels. Two tube-like closed systems comprised of the vessels start and stop at the heart. Blood is transported from the right ventricle to the lungs and back to the left atrium by one system, the pulmonary arteries.
- Your circulatory system is made up of blood vessels and heart vessels. About 60,000 miles of blood arteries make up your body.
- Blood is carried through blood arteries throughout the body. Blood is carried away from the heart through arteries. The blood is brought back to the heart by veins. Body cells and tissues are surrounded by capillaries that transport and absorb nutrition, oxygen, and other chemicals.
- Blood vessels are the channels or conduits through which blood is distributed to body tissues.
- The arteries (red) carry oxygen and nutrients away from your heart to your body's tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body's tissues.

<span>Early life was too simple to fully fix the sun or use higher functions to provide it's own energy. They were probably more like archaea that are seen around vents in extreme regions, such as the floor of the ocean or in high temperature pools in Yellowstone. These items "eat" the sulfur and other energy to create their needs. This would develop by necessity into mitochondria and chloroplast like bacteria as they ventured out from the vents to other areas and competed for heat and energy</span>
Answer:
It makes lipids, phospholipids as in plasma membranes, and steroids.
Explanation:
Answer:
Water is the universal solvent in biological systems. - TRUE
Water bathes organs in fluid, which provides protection and support. - FALSE
The high specific heat of water means that we only lose a small amount of heat when the sweat on our skin evaporates. - FALSE
Water plays a major role in our bodies’ chemical reactions. - TRUE
Explanation:
Water dissolves polar molecules hence critical solvent for energy molecules such as glucose and electrolytes such as sodium. Water also acts as a metabolite in reactions such as photolysis in photosynthesis and also in hydrolysis reactions. Water is a temperature buffer due to its high heat capacity (meaning it takes more energy to raise the temperature of water by one degree). This means it is good for the regulation of temperatures in the body.
Answer:
plants provide shelter and air for the animals
and when animals die they decompose and become fertilizer for the plant
