|
||||
|---|---|---|---|---|---|
| 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
🗑
