The Human Body
Organ #1 and function:
Cardiovascular: transport oxygen and nutrients to body, carries wastes away, and stabilizes body temp.
Organ #2 and function:
Reproductive: produce gametes, sex hormones, and offspring.

How organ systems work together to maintain homeostasis: All of the organ systems contain organs that are working together to maintain a stable environment by stopping things that will harm the body like waste, pathogens, and diseases and helping the body by stabilizing temp, transport oxygen, and more.
Define organ systems: a group of organs that act together to carry out complex interrelated functions with each organ focusing on a part of the task.
Define Homeostasis: a relatively stable state of equilibrium or tendency towards such a state between the different but interdependent elements or groups of elements of an organism, population, or group.
Define cells: Cells are the most basic unit of life. They are the smallest structural and functional unit of an organism.
Cell specialization vs cell differentiation: Cell specialization is specialized cells that have a specific structure and function. Cell differentiation is the process by which an unspecialized cell divided many times to produce specialized cells that work together and make up the body.
Stem cells and their usefulness: A stem cell is an unspecialized cell that can divide many times and give rise to different, specialized cells. They are useful because of their ability to divide indefinitely and to differentiate into many cell types.
Define Each tissue type, function, and an example
Nervous: made up of nerve cells called neurons. They together form the nervous system. Examples are the brain and spinal cord.
Muscle: made up of contractile filaments that move past each other and change the size of the cell. The three types are smooth muscle tissue, skeletal muscle tissue, and cardiac muscle tissue.
Epithelial: made of layers of tightly packed cells that line the surfaces of the body to protect, secrete, and absorb. Some examples are skin, the lining of the mouth and nose, and the lining of the digestive system.
Connective: made up of many different types of cells and they all support and the body and give it structure. Examples are bone, blood, fat, and cartilage.
