The area where chemicals pass between cells and blood is called the interstitial space. This space contains fluid that surrounds the cells and allows for the exchange of nutrients, waste products, and signaling molecules between the blood and the cells.
None - red blood cells are also called red blood corpuscles.
The walls which allow substances to pass backwards and forwards between the blood and the cells are called capillaries. They are microscopic blood vessels have walls which are 'leaky' which allows substances to pass backwards and forwards. Narrow arteries and veins are connected by capillaries.
Blood cells are called erythrocytes (red blood cells), leukocytes (white blood cells), and thrombocytes (platelets). Nerve cells are called neurons.
The lymph
Substances move down their concentration gradient. By that I mean where they move from an area of high concentration to an area of low concentration. This is essentially diffusion. Nutrients like glucose or oxygen that are high in the blood but low in the tissues, diffuse from the blood into the tissues. Wastes like carbon dioxide which are high in the tissues but low in the blood, diffuse from the tissues into the blood.
Interleukins
Blood picks up all the waste chemicals from your cells. It also delivers needed chemicals to all cells.
White blood cells, specifically neutrophils and macrophages, produce a variety of chemicals such as cytokines, chemokines, and reactive oxygen species. These chemicals help regulate the immune response, attract other immune cells to the site of infection, and destroy invading pathogens.
i think it's called antigen
diffusion: particles move from a high concentration to a low concentration
hemoglobin.
None - red blood cells are also called red blood corpuscles.
