Into which chamber of the heart do the superior vena cava, inferior vena cava, and coronary sinus return deoxygenated blood? Cir
azamat

Answer:

  • Human heart is comprised of four regions, components, zones or muscular containers. As, the blood quality is regulated by the blood, by keeping the deoxygenated form of blood apart from the oxygenated form of blood inside the heart and then provide suffiecient amount of materials, solutes, and other nutrients to the different tissues and organs of the human body in a proper manner.
  • The deoxygenated form of blood is collected and brought to the right atrium by <u>the superior and inferior venacava</u>, as it provides a more safer route for the transportation of these materials in order to remove the unwanted substance from it by sending it back to the lungs through the pulmonary artery.
  • Inside the lungs the blood is cleaned up and then sent back to the heart in order to be pumped into the different portions of the heart.

Which of these definitions have been paired with the correct type of cell?
patriot [66]

Answer:

B. Neurons are cells that conduct electrical impulses.

Explanation:

Red blood cells carry oxygen throughout the body. White blood cells protect against pathogens and aid in blood clotting after injury. Blood cells cannot contract.

Neurons generate and conduct electrical impulses. So this one is correct.

Epithelial cells line the cavities and surfaces of blood vessels and organs, protect underlying tissue, regulate the exchange of chemicals, and secrete various substances. They do not react to stimuli, however neurons do.

Smooth muscles helps the skeleton move, smooth muscle is found in blood vessels and some organs, and cardiac muscle helps the heart beat and pump blood. They are however, not components of blood.
