How do the four types of tissues help support the function of the heart?

Explanation:

Epithelial tissue-is the sheet of cells that cover exterior surfaces of the body lines internal cavities and passageway and forms certain glands

Connective tissue-it binds the cells and organs of the body together and function in the protection, support and integration of all parts of the body

Muscle tissue- it responds to stimulation and contracting to provide movement and it's occurs as 3types; skeletal,smooth and cardiac muscle in the heart

Nervous tissue-it allows the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body

the electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, x-rays, and gamma-rays.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
