tissue

• the four types of tissue is epithelial, connective, muscular and nervous
• epithelial tissue is the lining of organs or organs
• epithelial cells are closely joined together
• examples of epithelial tissue is skin, inside of organs and the inside of mouth
• connective tissue provides support and helps to hold body parts together
• connective cells are separated by a matrix
• examples of connective tissue is bone, cartilage, ligaments and blood
• muscular tissue is made up of skeletal, smooth and cardiac muscles
• skeletal muscles are attached to bones
• skeletal muscles have striations and voluntary control
• skeletal muscle examples are the hamstring, shoulder and abdominal muscles
• smooth muscles help with digestion and nutrient collection
• smooth muscles are not striated and have involuntary movement
• examples of smooth muscles are the walls of the stomach and intestines and the iris
• cardiac muscles make up most of the heart, and contract to pump blood
• cardiac muscles are striated and have involuntary movement
• examples of cardiac muscles are the aorta, the left and right ventricle
• nervous tissue is made up of neurons that carry messages, controlling body functions
• examples of nervous tissue is the spinal cord, brain and nerves
• similar cells are arranged into tissue to carry out a common function
