A flow chart shows the hierarchy of living organisms. From smallest to largest, this hierarchy includes: 1 An atom, with protons, neutrons and electrons. 2 Molecules such as the phospholipid shown, made up of atoms. 3 Organelles, such as Golgi apparatus and nuclei, that exist inside cells. 4 Cells, such as a red blood cell. 5 Tissues, such as human skin tissue. 6 Organs such as the stomach and intestine make up the human digestive system, an example of an organ system. 7 Organisms…
week 3 ANATOMY: Diagram of Human Tissue. A tissue is made up of a group of cells that usually look similar to one another and come from the same region in a developing embryo. The group of cells that make up a tissue have physiological functions that work together in a coordinated way to support special functions. The special function of a tissue is also influenced by the kind of material that surrounds the tissue and by communication among the cells of the tissue.
"Epithelial tissue is composed of tightly connected cells arranged in one or more layers. Epithelial tissues covers the whole surface of the body (it's your skin!) as well as lining all cavities and forming glands. Epithelial tissues as many functions including protection, sensation, diffusion, secretion, absorption and excretion." http://www.hartnell.edu/tutorials/biology/tissues.html
This is part 1 of a 7 part hands-on unit study on anatomy of the human body. Create edible models of human cells and DNA, look at cheek cells under a microscope, and more! These lessons are geared toward 4th-5th grade level children and their siblings. They were created by another creative mom for our weekly homeschool co-op. We meet each week for 2 1/2 hours and have 33 children between the ages of 1-13. Use these fun lessons with your classroom, family, after school program, or co-op!
