What is the function of the bloodstream?

What is the function of the bloodstream?

Functions of blood Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body. Nutrients from the digestive tract and storage sites to the rest of the body.

What are the 2 major components of blood?

What are the components of blood?

  • Red blood cells (erythrocytes). These carry oxygen from the lungs to the rest of the body.
  • White blood cells (leukocytes). These help fight infections and aid in the immune process. Types of white blood cells include: Lymphocytes.
  • Platelets (thrombocytes). These help in blood clotting.

What are the functions of red blood cells?

What Is the Function of Red Blood Cells? Red blood cells carry oxygen from our lungs to the rest of our bodies. Then they make the return trip, taking carbon dioxide back to our lungs to be exhaled.

What are the types of blood and their functions?

Blood is made mostly of plasma, but 3 main types of blood cells circulate with the plasma:

  • Platelets help the blood to clot. Clotting stops the blood from flowing out of the body when a vein or artery is broken.
  • Red blood cells carry oxygen.
  • White blood cells ward off infection.

What carries the blood throughout the body?

The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Why is blood so important?

Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.

What are the 3 stages of blood clotting?

1) Constriction of the blood vessel. 2) Formation of a temporary “platelet plug.” 3) Activation of the coagulation cascade. 4) Formation of “fibrin plug” or the final clot.

What are the 5 components of blood?

Whole Blood. Whole blood contains red cells, white cells, and platelets (~45% of volume) suspended in blood plasma (~55% of volume).

  • Red Cells. Red blood cells (RBCs), or erythrocytes, give blood its distinctive color.
  • Platelets.
  • Plasma.
  • Cryo.
  • White Cells & Granulocytes.

    What is the largest artery found in the body?

    The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
