There are many different types of Cells. Some fight germs, some make up many different styles of body parts and some deliver many different types of substances to your body's systems.
i dont know the answer.
no. a kidney is not composed of body cells. but liver, sperm, and a single bone are composed of body cells. :)
Yes, the kidney is composed of body cells. In fact, all of our organs and internal parts are composed of different body cells.
oxygen and glucose
The circulatory system is they system in the body that transports material throughout the body. It carries nutrients, water, and oxygen to all the cells and carries waste material away from the cells.
if white blood cells get destroyed the body loses it's power of defence against any infections and foreign substances.
Yes, all plants and other living substances have cells
Blood carries all necessary chemicals and compounds needed for survival. It travels through blood vessels (specifically the arteries and arterioles from the heart) which innervate all parts of the body.
why can small cells exchange substances more readily than large cells?
There are many different types of Cells. Some fight germs, some make up many different styles of body parts and some deliver many different types of substances to your body's systems.
They are sheets of cells [Epithelial tissue or epithelium] that covers the body surface or lines a body cavity. They form bounderies between different environments and nearly all substances received or given off by the body must pass through some sort of epithelium.
i dont know the answer.
Body cells. This distinguishes them from sex cells, gametes.
No.
capillaries have walls thin enough to allow the exchange of materials between cells and the blood. Their extensive branching provides a sufficient surface area to pick up and deliver substances to all cells in the body.
