Tissues are made up of different types of cells working together to perform a body function.
cells make tissues which make organs
Cells working together for the same purpose is what forms tissues. Cell reproduction happens continuously through mitosis and cytokinesis.
a group of cells doing the same job and are the same working together are called tissues then tissues working together make organs but not sure if that answers ur question
Repair body cells and tissues.
Organelles make up cell. Cells make up tissues. Tissues make up organ. Organs make up organ systems. Organ systems make up organisms. organelles-->cells-->tissues-->organs-->organ systems-->organisms
protein
RBC used to supply oxygen and get back co2from tissues.
proteins are nutrients that are used to repair body cells and tissues.
Mainly carbon, nitrogen, hydrogen, and oxygen.
Carbohydrates are used as a main source of energy, burns quickly and stored in blood and liver, Fats are used a another source of energy but burns after Carbohydrates and stored around organs and under skin, Proteins are used to build and repair body parts and also make up large parts of tissues as bone, muscle and skin (Protein make up cytoplasm in cells!) and Fiber which helps with your muscles.
Stem cells could potentially be used as a source of renewable healthy cells and tissues.
