Human blood is an example of tissue. Tissues are groups of similar cells that perform a specific function and are found in animals and plants. There are four basic types of tissue in the human body: epithelial, connective, muscle, and nervous. Blood is a type of connective tissue that is made up of cells suspended in a liquid matrix, or plasma. The cells in blood include red blood cells, which carry oxygen to the body’s tissues, white blood cells, which help to fight infections, and platelets, which are involved in blood clotting.
A. Organelles are tiny cellular structures that perform specific functions within a cell.
C. Organic compounds are compounds that contain carbon and are found in living organisms.
D. Inorganic compounds are compounds that do not contain carbon and are not found in living organisms.
