What are the foundational building materials found in the human body?\u00a0<\/b><\/p>\n
\u00a0<\/span>In lesson 1 were going to talk about the foundational building materials of the body:<\/span><\/p>\n Cells are the smallest unit of life meaning they are the smallest structural and functional unit of a living organism. They are the lowest level of organization in every life and are often referred to as the \u201cBuilding blocks of Life\u201d. \u00a0 Cells come in different shapes and sizes and have the ability to replicate themselves independently. As humans we have many cells, making us Multicellular, which makes up our body.\u00a0 Did you know that the human body is made up of trillions of cells?\u00a0\u00a0<\/span><\/p>\n \u00a0<\/span>Tissues are cells that are grouped together to carry out a specific function.\u00a0 Humans have different types of tissue throughout the body.\u00a0 There are four basic types of tissues: epithelial, muscle, nerve, and connective. \u00a0 Epithelial tissue covers your organs and body, muscle tissue is the tissue that makes up the muscles of the body, nervous tissue is found mostly in the nervous system including the brain and spinal cord, and connective tissue connects other tissues.\u00a0 Fun fact:\u00a0 Did you know that blood is a tissue?\u00a0<\/span><\/p>\n \u00a0<\/span>Organs are when two or more tissues come together to perform a complex function.\u00a0 Within your body, there are 78 organs with 5 being considered vital for life.\u00a0 Your brain, heart, lungs, kidney, and liver are considered your vital organs.\u00a0 Organs can also be found on the outside of your body.\u00a0 Take your skin for example.\u00a0 Doctors considered your skin to be the biggest organ. Your organs are important for your body to function.\u00a0 They can help with how you breathing (lungs), your brain helps to make decisions, eyes help you see, kidneys help clean your blood, your heart pumps blood throughout the body,\u00a0 using the restroom, and digesting food to name a few. Did you know \u201cThe brain consumes up to 20% of the energy used by the human body\u201d?<\/span><\/p>\n \u00a0<\/span>Resources<\/b><\/p>\n Research\/Reflect\/Brainstorm\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/b><\/p>\n \u00a0<\/b>Grab a notebook or your journal and research the following:\u00a0<\/span><\/p>\n \u00a0<\/b>Group \u2013 Watch the following video:\u00a0 <\/span>How To See Germs Spread Experiment (Coronavirus)<\/span>. <\/span><\/p>\n\n
