The Human Body
This explains the biological processes and systems of the human body.
| Term | Definition |
|---|---|
| Cell | The smallest and basic unit of LIVING organisms |
| Lungs | Not only is the organ part of the respiratory system, it is also part of the endocrine system to generate hormones and prevent clotting in Pulmonary circulation. It is one of the most vital organs. |
| Biosphere | Composed of complex relationships from a local to a global scale |
| The 4 types of human tissues | Nervous Tissue, Muscular Tissue, Epithelial Tissue, and Connective Tissue |
| Nervous Tissue | Reacts to stimuli and transits messages throughout the body |
| Muscular Tissue | Specialized for movement and contraction of body and its parts |
| Epithelial Tissue | This tissue lines the surface of organs and body cavities. |
| Connective Tissue | Most widespread used tissue in the body; connects and supports other tissues |
| The 3 major effects humans have on the biosphere | Population Size, Consumption (using more resources), and Technology |
| Homeostasis | This describes the relatively constant internal physical and chemical conditions that organisms maintain despite changes in internal and external environments. |
| Feedback Inhibition | The process in which a stimulus produces a response that opposes the original stimulus (example: throwing up) |
| Respiratory System | This organ system picks up oxygen from the air we inhale and releases carbon dioxide as we exhale |
| Lymphatic System | This organ system is a network of vessels, nodes, and organs that collects the lymph that leaves capillaries, "screens" it for microorganisms, and returns it ot the circulatory system |
| Skeletal System | This organ system supports the body, protects internal organs, assists in movement, stores minerals, and is a site of blood cell formation |
| Muscular System | This organ system is responsible for the voluntary and involuntary movements of out body |
| The Integumentary System | This organ system serves as a barrier against the outside environment, such as protecting our skin, regulation body temperature, removes wastes such as sweat, produces vitamin D, and gathers information. |
| The Endocrine System | This organ system is consisted of glands that help regulate hormones such as growth and reproduction. |
| Infectious Diseases | These are microorganisms (viruses, bacteria, fungi, protists, and parasites) that disrupt the normal function of the body. |
| Inflammatory response | This occurs when infected areas become painful or inflamed |
| Antigen | This is any foreign substance that can be taken in to stimulate an immune response in the body. |
| Glucose concentration composition | Controlled by insulin and glucagon |
| How does the body maintain water balance? | The endocrine system maintains homeostasis by losing water through sweat to get rid of internal toxins |
| How many bones does the human skeletal system have? | 206 bones |
| Circulatory System | This organ system transports oxygen, nutrients, and other substances throughout the body and removes wastes from tissues |
| How do the Kidneys help maintain homeostasis? | They respond directly to the composition on the blood. They also are involved within the endocrine system to get rid of waste/toxins. |
| Excretory System | This organ system includes the lungs, liver, and kidneys in order to help with the excretion of metabolic wastes from the body |
| Digestive System | This organ system converts food into small molecules that can be used by the cells of the body. There are four phases: ingestion, digestion, absorption, and elimination. |
