Anatomy 3: The Cell
Organization of the Human Body--Maintaining a homeostatic environment--Systems
| Question | Answer |
|---|---|
| Cellular Level of Organization: | Basic structure and function level of human body |
| Why is the cellular level important in regards to diseases? | It is where disease originates |
| What is Homeostasis? | Day to day REGULAR activity of human body (balanced) |
| Disease: | A result of homeostasis in the cellular level |
| Cytology: | Anything related to cell (CYT) |
| Acute Homeostatic Imbalance: | Small change in the cell balance |
| Chronic homeostatic imbalance: | Disease, body may adjust or shut down |
| Basal Metabolic rate: | The optimum metabolism rate unique to individuals |
| How is metabolism divided? | Catabolic and Anabolic |
| Catabolic: | To break down nutrients, releases energy |
| Anabolic: | To form more complicated molecules from simple, requires energy |
| Thyroid glands: | Regulate metabolism |
| Explain the scientific implications of being tired: | The thyroid glans it not producing enough nutrients to regulate metabolism--you're tired |
| Explain the diveristy of cells: | Cells are unique in their funciton and shape--they are differentiated |
| Histology: | Study of tissues |
| What are the four main tyipes of tissues? | Epithilium, connective, muscle, and nervous |
| Epithilium: | Tissue that lines and covers (SKIN) |
| Connective: | Blood, bone cartilage, fat--most abundant in body |
| Muscle: | Specialized (can contract to give movement) |
| Nerouvs: | Conducts electricity, which is how the organs communicates |
| Micrsocopic anatomy: | Combination of cytology and histology: study of tissue cells |
| What is the definition of an organ? What is an organ? | A combination of two or more tissues: organs work together in a system |
| What is the optimum glucose level in body? | 90 |
| What happens when you consume a lot of sugar? What is the scientific term of having too much sugar? | Homeostatic imablance, you become hyper glycimia |
| How do you lower your level of glucose? | Pancreas releases insulin, whiich goes to cell receptor to reduce level to 90 |
| How is type I diabetes related to the increase in glucose level? | Type I diabetes is when the pancreas can't produce insulin, so give them insulin to treat them |
| What is type II diabetes? | Pancrease makes insulin, but cells don't respond to insuliin, so get them to change their diet to help them, but they will never return to homeostatic balance |
| What is it called to have too little level of sugar? How is this cured? | Hypo glycimia--EAT SOMETHING |
| What is the optimum blood pressure level in the human body? | 120/80 |
| How do you overcome a blood pressure of 130/100? | You must lower heart rate by neurotransmitters telling heart not to pump much blood by reducing the force of heart muscle contraction. |
| What is the vasodialator? | Reduces blood pressure by forcing vessels to expand or dialate |
| What is hypertension? | When the blood vessels rapture; it is a chronic problem |
| What is the simple definition of hypo tension? | Below normal blood pressure level; such as having a pressure of 90/40 |
| What is the medical implications of having hypo tension? | Your blood vessels don't have enough pressure to send blood upto the brain; thus, you may be dizzy at times |
| define orthostatic blood pressure? | Low blood pressure when you're standing |
| define systolic? Which (numerator or denominator) is systolic in this problem: 120/80 | Blood pressure when heart is contracting; 120 is the systolic pressure |
| What is the key, central information radiating throughout this unit? | All systems interact with other systems to maining a homeostatic balance |
| SYSTEMS | SYSTEMS |
| How many total systems exist of the human body? | 11 |
| What are they? | Skin, skelatal, muscular, nervous, endocryn, cardiovascular, lymphatic, respitory, digestive, urinary, reproductive |
| What makes up the nervous system? | Brain and spinal cord, which extends through the abdomen |
| What makes up the endocryn system? | Glands that make hormones and thyroid gland (regulates homeostasis) |
| What makes up your cardiovascular system? | Heart and blood vessels |
| What makes up the lymphatic System? | Series of vessels that are in charge of draining body fluids |
