Minerals salts: Substances that can be found in living things in the form of disolved ions.
Carbohydrates: Monosaccharides are composed of one molecule, disaccharide are formed when two monosaccharides Are joined. Polysaccharides are formed When many monosaccharides are joined
Lipids: These molecules vary widely in chemical structure, include facts, phospholipids And cholesterol.
Proteins: These large biomolecules are composed of many smaller molecules called amino Acids. Ej: collagen, haemoglobin and antibodies.
Nucleic acids: These macromolecules are composed of smaller ones called nucleotides they are Two types: DNA and RNA.
Organ: a group of tissue (organs) that work together to perform (one or more functions)a specific function or action.

-glandular: makes up the glands, it produces and secretes substances, types: exocrine glands, Endocrine glands, mixed glands.
connective this tissue Connects other tissue
-three Components: cell, fibres and matrix
-the Several types:
osseous or Bone tissue= osteoblasts, produces a strong, solid matrix.
adipose Tissue= is made up of adipocytes, they are store lipids
cartilage tissue=cells are called chondrocytes, Contain elastic fibres and produce solid
dense connective tissue=(tendons)
blood Tissue=is made up of white bloods cells and red
muscle it Contains protein filaments of actin and myosin, they are three types:
-smooth muscle tissue -skeletal -cardiac
nervous transmit and receive information throughout the body, two types:
-nervous: They transmit nerve impulses -glial Cells: they nourish and support the neurons, they do not transmit nerve Impulses.
