Which Two Major Systems Work Together To Make Sure That Your Body Can Have Oxygen

Is the circulatory system the most important body system?

The human body systems are all of equal importance. Without your nervous system, your heart would not know how to operate. However, if the circulatory system was not perpetually pumping oxygenated blood to your brain its cells would die. Your circulatory system provides every single cell in your body with oxygen and nutrients. However, without the respiratory system, there would be no oxygen in your blood to pump. When the cells go through cellular respiration and release wastes like carbon dioxide and water, they would have no where to go if the blood didn't carry them to the organs of the endocrine system. You can't order systems like that. Don't you think that if one was of less important than another we would have evolved to make just one system that did everything? Yes, the circulatory system is very important, but, along with the systems that help it function, it helps the systems that help it function. There is not a single most important system.

How is the body dependent upon the circulatory system? ?

The circulatory sends blood all throughout the body, bringing nutrients and oxygen to the muscles and tissues. Oxygen and nutrients bring energy to your body. Without it, you would die.

Science (Respiratory system)?

The main function of the respiratory system is to deliver oxygen to the blood.

When you breathe in, air travels into the trachea. The diaphragm is a dome shaped sheet of muscle between the chest and the abdomen. When this muscle expands and contracts, it causes the lungs to inflate, and deflate.

The left and right bronchi branch off from the trachea and carry oxygen further into the lungs. The right bronchus is wider, shorter, and steeper than the left.

Bronchioles are the thousands of tiny tubes that branch out from the two bronchi and carry oxygen deep into the lungs.

At the ends of each bronchiole, there are clusters of air sacs. Adult lungs contain about 600 million of these spongy sacs. It is through the extremely thin walls of the alveoli that oxygen is diffused into, and carbon dioxide is taken out of the blood.

The thin walls of the alveoli are covered in a lattice of tiny blood vessels called capillaries. Oxygen passes into these capillaries, and is carried to the heart while carbon dioxide moves from the blood into the alveoli to be expelled.

I'm not exactly sure how the digestive system is related to this at all. But the circulatory system is an organ system that moves nutrients, gases, and wastes to and from cells to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory system. The lymphatic system, on the other hand, is an open system.

Hope this helps. And, good luck!

Why does an animal with waterproof skin need a respiratory system?

To breathe...? The body needs air, and the respiratory system delivers it.
