One of the many functions of the circulatory system is to bring oxygen to cells.
respiratory system
No. Nerve cells are just cells. The brain is an organ and the nervous system is an organ system
the hierarchy of cells from cells onward is :cells, tissues(this is the ensemble of cells), organ, organ system, organism.
circulatory system, digestive system, respiratory system
organ system
tissue- a group of like cells organ- like tissues organ system- organs with related function (cell-> tissue -> organ -> organ system)
the respiratory system brings oxygen into the body
The circulatory system, also called the cardiovascular system, is the heart and the network that brings blood to body tissue. It carries oxygen and nutrients to cells.
The cardiovascular system, specifically the red blood cells, is what transports oxygen to the muscles.
The Lungs
No. Nerve cells are just cells. The brain is an organ and the nervous system is an organ system
there is no such organ
Yes. The organ system itself is made up of cells.
The Respiratory System.
The respiratory system seems like the obvious answer, but you used the word absorb. The respiratory system takes air into the lungs, but the red blood cells (erythrocytes) absorb the oxygen out of the air taken into the lungs. The circulatory system then delivers these red blood cells to the capillaries where the oxygen is traded for carbon dioxide as the cells need.
