The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. The carbon dioxide produced during metabolism is carried back to the lungs by the blood, where it is then exhaled (breathed out).
How does blood function with regard to transportation in the body?
Blood Provides the Body’s Cells with Oxygen and Removes Carbon Dioxide. Blood absorbs oxygen from air in the lungs. It transports the oxygen to cells throughout the body, and it removes waste carbon dioxide from the cells. In the lungs, the carbon dioxide moves from the blood to the air and is exhaled.
How does blood function as transportation in the body quizlet?
How does blood function as transportation in the body? Blood caries oxygen and nutrients to cells, transports carbon dioxide and nitrogenous wastes from the tissues to the lungs and kidneys and carries hormones from endocrine glands to target tissues.
How does blood function as a transport medium?
Formed elements are the cellular components of the blood, and the liquid part is plasma. Blood is the primary transport medium that is responsible for continuously supplying nutrients and oxygen to the active cells in the body.
How does blood plasma transport nutrients?
Plasma contains about 92 percent water. This water helps to fill up blood vessels, which keeps blood and other nutrients moving through the heart. The remaining 8 percent of plasma contains several key materials, including: proteins.
What is the main function of blood quizlet?
What are the 3 functions of blood? (1) Transport – oxygen, nutrients, hormones and removes wastes. (2) Regulation – pH, temperature, volume of fluid in circulation. (3) Protection – prevent blood loss (clots), prevent infection (antibodies, immune proteins & WBCs).
What are the three functions of the blood quizlet?
Blood carries oxygen from lungs to peripheral tissues, and brings back carbon dioxide back to the lungs. Blood distributes nutrients absorbed by Digestive Tract, adipose tissue or in the Liver. Carries hormones from endocrine glands and carries wastes from tissue cells to the kidneys for excretion.
Does blood carry gas?
Oxygen is transported in the blood in two ways: A small amount of O 2 (1.5 percent) is carried in the plasma as a dissolved gas. Most oxygen (98.5 percent) carried in the blood is bound to the protein hemoglobin in red blood cells.
Why is blood plasma a good transport medium?
Plasma serves as a transport medium for delivering nutrients to the cells of the various organs of the body and for transporting waste products derived from cellular metabolism to the kidneys, liver, and lungs for excretion.
How does blood transport oxygen and carbon dioxide?
Oxygen is carried both physically dissolved in the blood and chemically combined to hemoglobin. Carbon dioxide is carried physically dissolved in the blood, chemically combined to blood proteins as carbamino compounds, and as bicarbonate.
What substances are transported by blood plasma?
Plasma carries water, salts and enzymes. The main role of plasma is to take nutrients, hormones, and proteins to the parts of the body that need it. Cells also put their waste products into the plasma. The plasma then helps remove this waste from the body.
What exchange takes place between blood capillaries and tissues?
Exchange of molecules
Oxygen diffuses through the capillary wall, into the tissue fluid and the cells. Carbon dioxide diffuses from the cells into the tissue fluid, then across the capillary walls into the blood plasma .
