25 Questions

1. Openings of tracheae

2. Exit of water vapor through leaf stomates

3. The removal of metabolic wastes produced in the body

4. Urine collects until it is expelled via the urethra

5. The removal of indigestible material

6. Pores in stems

7. Function to maintain the osmolarity of the blood -excrete numerous waste products and toxic chemicals -conserve glucose - salt - and water

8. Regulate the concentration of salt and water in the blood through the formation and excretion of urine

9. Carbon dioxide is released from the tissues into adjacent tracheae through spiracles

10. Created when exiting and reentering at different segments of the nephron - with tissue osmolarity increasing from cortex to inner medulla

11. Anatomic arrangement of permits the reabsorption of ((% of the filtrate in the collecting tubules -makes the production of concentrated urine possible

12. Nephron secretes substances such as acids - bases - and ions like potassium and phosphate from the interstitial fluid into the filtrate by both passive and active transport

13. Divded into three regions: outer cortex - inner medulla - renal pelvis

14. Two pairs of nephridia in each body segment excret water - mineral salts - and nitrogenous wastes in the form of urea

15. The reabsorption of water in this zone of the kidney - which permits the concentration of urine - dpeends on the permeability of the collecting tubules to water

16. Lungs - liver - skin - and kidneys

17. Essential substances and water are reabsorbed from the filtrate and returned to the blood -occurs primarily in the proximal convuluted tubule and is an active process

18. The fluid and small solutes entering the nephron -isotonic with blood plasm

19. An organelle specialized for water excretion by active transport

20. Excrete water and dissolved salts

21. Leads to the production of carbon dioxide and water

22. A hormone that causes an increased exchange transport of sodium and potassium ions along the distal convoluted tubule - the collecting tubule - and the collecting duct - resulting in a decreased excretion of sodium ions in the urine and an increased

23. Produced by the deamination of amino acids in the liver and diffuses into the blood for ultimate excretion in the kidneys

24. Processes nitrogenous wastes - blood pigment wastes - and other chemicals for excretion

25. Hypertonic to the blood
