Module 6 Bio
| Term | Definition |
|---|---|
| Central Nervous System | Brain and spinal cord, serves as the main processing system for the whole nervous system |
| Neurons | Nerve cell that conducts electrical signals through the body |
| Sensory Nervous system | transmits impulses from sense organs to the central nervous system |
| Motor nervous system | transmits impulses from the central nervous system out to the body's muscles and glands |
| Peripheral Nervous systme | Made up of neurons and sends information to the central nervous system |
| Endocrine system | Sends hormones which come in contact with your body's cells |
| How do the Respiratory and Circulatory systems work together? | Work together to carry oxygen to the body's cell and remove carbon dioxide from those cells |
| Circulatory system | Delivers oxygen through the body. Removes carbon dioxide. Fights disease and seals cuts |
| Systolic pressure | Maximum pressure exerted when the heart pumps out |
| Diastolic pressure | Minimum pressure exerted when the heart is relaxed |
| Pancreas | Produces hormones that regulate blood sugar, enzymes that break down food, and sodium carbonate that neutralizes stomach acid. |
| Liver | Produces bile, liquid loaded with lipids and salts. |
| Gallbladder | This is where bile is stored |
| Excretory System | Skin, lungs, liver, and kidneys |
| Skeletal System | Protection, support, movement, mineral storage, and blood cell formation. |
| Integumentary System | Skin (largest organ) is part of this system. Nails, glands,and hair are included. Offers protection, excretion, body temperature regulation, gathering information, and Vitamin D production. |
| Sperm Productoin | Sperm is produced in the testes, then stored in the epididymis. Then during ejaculation, sperm is propelled out this into the vas deferens a duct that merges with the urethra. The urethra is a tube that leads out of the penis. |
| Female reproduction system | Eggs are produced in the ovary. The Fallopian tube transports the egg to the uterus. |
| Blastocyst | fertilized cells forms into a hollow ball after several divisions |
| Gastrulation | Development of skin and nervous system, muscles, bones, and blood cells. |
| Neuraltion | First step in the development of the nervous system |
| External nonspecific defense | Skin, saliva, and mucus |
| Internal nonspecific defense | Inflammatory response, white blood cells,and fever |
| Immune System | Antigens on pathogens enter the body. The corresponding antibodies bind to these antigens and make it possible for lymphocytes to destroy it. |
