Teas 6 Science Questions and Answers
1. Muscles involved in inhalation and do they expand or contract? - ANSWER:
Intercostals and diaphragm contract
2. Part of brain that monitors CO2 to regulate breathing - ANSWER: Medulla
oblongata
3. Two main functions of nucleolus - ANSWER: Protein synthesis, synthesis and
storage of RNA
4. Function of ribosomes - ANSWER: Synthesize proteins from RNA
5. Golgi complex function - ANSWER: Synthesizes materials such as proteins
that are transported out of the cell
6. Endoplasmic reticulum - ANSWER: transport system of cell
7. Mitochondria functions - ANSWER: Production of cell energy; cell signaling;
cellular differentiation; cell cycle and growth regulation
8. Events of prophase - ANSWER: chromatin thickens into chromosomes;
nuclear membrane begins to disintegrate; pairs of centrioles move to opp sides
of cell and spindle fibers form; mitotic spindle starts to move chromosomes
around
9. Connective tissue - ANSWER: bone, cartilage, tendons, ligaments, fat, blood,
lymph
10. Hyperventilation does what to pH? - ANSWER: Increases blood pH during
acidosis; slowing breathing during alkalosis will decrease pH

14. Lymph vascular system functions - ANSWER: Return of excess fluid to blood;
return of proteins from capillaries; transport of fats from digestive tract; disposal
of debris and cellular waste
15. Thymus functions - ANSWER: Thymosin promotes Tcell formation, T cells
mature here
16. Lymphoid organs include - ANSWER: adenoids, tonsils, spleen, thymus,
appendix, lymph nodes, patches in small intestine
17. Spleen functions - ANSWER: filter unwanted materials from blood, including
old RBCs; help fight infection by filtering pathogens.
18. Liver functions - ANSWER: IGF-1, bile, angiotensinogen, thrombopoietin,
hepciden, betatrophon, cytochrome p450. Production of cholesterol; storage of
excess glucose in form of glycogen; regulation of amino acids; processing of
hemoglobin; conversion of ammonia to urea; purification of blood; regulation of
blood clotting; controlling infection via boosting immune factors and removing
bacteria. Bill's putt putt golf closed
19. Bile - ANSWER: Increases the absorption of fats, aids abs of vitamins A, D, E,
