haemoglobin in red blood cells
The cardiovascular system transports oxygen and nutrients to cells for energy production and maintenance. It also carries waste products such as carbon dioxide and cellular byproducts away from cells for excretion and recycling.
Blood it's simple :)
The cardiovascular system, specifically the red blood cells, is what transports oxygen to the muscles.
red blood cells
The lungs take oxygen into the body and the blood transports oxygen throughout the body.
Blood cells carry the oxygen through the blood stream to the other cells in the body.
The molecule that carries oxygen in the human body is hemoglobin, which is found in red blood cells. Hemoglobin binds to oxygen in the lungs and transports it to tissues throughout the body.
This transport is by simple diffusion:from a high of oxygen (in the blood) to a low (in the cells).
The circulatory system transports materials in the body.
hemoglobin
Blood transports oxygen to the cells around the body. It is important because oxygen is necessary from the electron chain which is where most of the bodies energy comes from.
Hemoglobin is the iron-containing molecule that transports oxygen. Hemoglobin is found in red blood cells.
