Why do most tissues have a greater supply of capillaries than veins and arteries?
Capillaries service cells, arteries and veins transport blood to and from capillaries, respectively.
Does blood flow more rapidly in the capillaries or in arteries?
Remember arteries come from the heart, and veins go from the organs back to the heart. Therefore, as the heart is the main pump, the arteries have the greatest pressure, so "the blood flow is more rapid in arteries."
How does the blockage of a coronary artery lead to a heart attack?
arteries provide oxygenated blood to the tissues they supply. ergo, a coronary artery that is blocked cannot deliver oxygen to the tissue it is supplying, and all that tissue dies... literally dies as in tissue necrosis, cellular death and just becomes a hunk of meat that flaps along with the tissue around it that still does get oxygen and can move. If a large enough piece of tissue dies or if multiple arteries get blocked then heart stops beating and death occurs.
In which direction do arteries carry blood twoards or away from the heart?
Arteries take blood from the heart to the body. Capillaries are tiny blood vessels that enable substance exchange between the blood and the body tissues. Veins carry blood back to the heart.
How can small arteries help control the distribution of blood to tissues which have a high demand for oxygen and nutrients?

Blood is transported from the right and left ventricles of the heart to all body parts by the?
Blood is transported from the right and left ventricles of the heart to all body parts by the arteries. These blood vessels carry oxygenated blood from the heart to the tissues and organs, supplying them with oxygen and nutrients for proper function.
Does ldl's transport cholesterol from the peripheral tissues to the liver?
no
What are some examples of peripheral tissues in the human body?
Some examples of peripheral tissues in the human body include skin, muscles, nerves, and blood vessels. These tissues are located outside of the central organs such as the brain and heart.
What is the vessel with valves that carry blood from the peripheral tissues to the heart?
Veins carry blood from the tissues to the heart.
What does your arteries do?
they carry oxygenated blood, to all the tissues of our body.
What function do the arteries perform for the cells?
Arteries helps in carrying oxygenated blood from heart to different tissues of body.
What are the basic tissues of the nervous system?
the brain, spinal cord and peripheral nerves
What are the effects of thyroid hormones on peripheral tissues?
increased sensitivity to sympathetic output
What is peripheral blood flow?
Peripheral blood flow refers to the circulation of blood through the blood vessels outside of the heart and lungs, supplying oxygen and nutrients to the body's tissues and organs. It is regulated by mechanisms that control blood vessel diameter and blood pressure to ensure adequate oxygen delivery to all parts of the body. Disorders affecting peripheral blood flow can lead to conditions such as peripheral artery disease or Raynaud's disease.
What does the nervous system compose of?
peripheral nervous systemthe peripheral nervous systemperipheraThe peripheral nervous system branches from the central nervous systemIt is called the Peripheral Nervous System(PNS).
What are peripheral tissues and how do they function in the human body?
Peripheral tissues are the tissues in the body that are located outside of the central organs like the heart and brain. These tissues play important roles in supporting bodily functions such as movement, digestion, and immunity. They receive signals from the central nervous system and work together to maintain the body's overall health and function.
What does Lymphocyte production involves?
bone marrow, thymus tissue, and peripheral lymphoid tissues.
