How does the cardiovascular system deliver nutrients and oxygen to all cells in the body via the flow of blood? Select all corre
Alex

Answer:

1: (The arteries carry blood away from the heart; the veins carry it back to the heart.)

2: (In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)

4: (Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)

Explanation:

The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. ... In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta).

The arteries carry blood away from the heart; the veins carry it back to the heart. ... The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.

The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

<h3><u>Explanation;</u></h3>
  • <em><u>Skeletal system is a system in the body that is made up of cartilage and calcified bone that work together by helping in the smooth movement process of the body. </u></em>
  • <em><u>Circulatory system on the other hand is a system of the body that is made up of blood vessels that carry blood away and towards the heart. The system helps in transport of oxygen and nutrients in all the body tissues, and also transport of carbon dioxide and wastes out of the tissues.</u></em>
  • <em><u>The calcified bones of the skeletal system work with the circulatory system, such that the bone marrow in these bones helps in the production of blood cells such as red blood cells and white blood cells.</u></em>
