"Cholesterol is bad for you" do you agree with this statement? - -Cholesterol isn't bad, but too much is. - Our body needs it to maintain the integrity of the plasma membrane - Synthesis of the steroid hormone to maintain homeostasis Chondroblasts secrete - -cartilage Describe the frontal cut - -Divides body into anterior and posterior (front and back) Describe the sagittal cut - -Divides body into left and right Describe the transverse cut - -Divides body into superior and inferior Fibroblasts secrete __________` - -CT proper Give an example of a polar covalent molecule - -Water Hemapoietic stem cells secrete ________ - -blood How many organ systems are required for homeostasis? - -Only 10 out of the 11 organ systems; the reproductive system isn't required for homeostasis How would you convince me that bone tissue and blood belong to the same primary tissue? - -1.) They are both derived from mescehnyme 2.) Both have a matrix If a red blood cell is placed in a 9% NaCl solution ____________ - -the cell will crenate (shrink) water will move out of the cell In the ventral body cavity, the thoracic cavity and abdominopelvic body cavity are divided by the ________________ - -diaphragm Name 3 major parts of a cell - -nucleus, cytoplasm, plasma membrane Name 4 organic compounds - -carbohydrates, lipids, proteins, nucleic acids Organs in the ventral cavity are each surrounded by______________ - -serous membrane Osteoblasts secrete ______ - -bone Structures in the dorsal body cavity are each surrounded by ______________ - -meninges (a type of membrane) T/F: A solution with high acidity has a high pH - -False T/F: Saturated fats stimulate the formation of LDLs - -True T/F: The heart is inferior to the sternum - -False T/F: The same number of protons and electrons are in an atom - -True The disaccharide sucrose is formed via dehydration synthesis of ______________ - -one molecule of fructose one molecule of glucose The dorsal body cavity contains _____________ - -cranial cavity and vertebral cavity These are known as the only unicellular exocrine glands in the human body - -Goblet cells These inorganic compounds act as proton acceptors ______ - -Bases These membrane junctions are also known as communicating junctions. - -Gap Junctions What are 2 benefits of compartmentalization? - -- prevents the spread of infection - holds organs in anatomical position What are the cell type derived from mesenchyme? - -osteoblasts, chondroblasts, fibroblasts, hemapoietic stem cells What is the net charge of an atom? - -zero What is the overall charge of the atomic nucleus? - -positive (because nucleus contains only protons and neutrons) What would happen if the blood pH fell below homeostatic range? - -a buffer would arrive and act as a base to increase the blood pH (by accepting the H+ ) What would happen if the blood pH increased beyond homeostatic range? - -a buffer would arrive and act as an acid to lower the blood pH (by releasing H+) What's a buffer? - -It acts as an acid or base to increase or decrease pH What's one FUNCTIONAL difference between cilia and flagellum? - -Cilia: beats to create a unidirectional current that moves substances across the surface of the cell (cilia moving mucus in nose) Flagellum: Beats to move the cell itself (spe
