| The indented area where the ureters, renal arteries and veins enter and exit kidney | hilum |
| Opening of the ureter where it leads into the kidney- where urine collects | Renal Pelvis |
| Renal Pyramids are here, and collects urine | Renal Medulla |
| Outer portion of the kidney | Renal Cortex |
| The kidneys perform _____filtration | chemical |
| The kidneys regulate ______ volume in the body | fluid |
| The kidneys help regulate _______ | electrolytes and ph |
| Kidneys help regulate the bodys _____ (vs) | blood pressure |
| The kidneys regulate _______ | Hematopoiesis |
| Renal blood vessels include ______, ________ and Venous _______. | arteries, arterioles and return |
| afferent arteriole takes blood to/from the glomerulus. | TO |
| What is part of the renal corpusule and the site of filtration. | Glomerulus |
| Efferent arterioles take blood To/ From the glomerulus | away |
| The efferent arterioles open up into a capillary bed that surrounds the tubules of a _______? | nephron |
| 1) FILTRATION, (2) TUBULAR _________, (3) ___________ SECRETION | REABSORPTION, TUBULAR |
| The basic functional unit of the kidney | Nephron |
| Nephron structure Renal ______ & Renal _______ | Corpusule/ Tubule |
| Glomerulus, located in the Renal _______, are high pressure __________, full of tiny holes called______ | Corpusule/ capillaries/ Fenestrae |
| A thin walled sac that surrounds the glomerulus, and catches filtrate. | Glomerual Capsule |
| The renal filtrate flows into the renal _______ | tubule |
| Where is the filtrate's content and deliver it out to the nephron | Renal Tubule |
| Urine is formed by 3 major actions_______ filtration, Tubular _______ and Tubular______. | glomerual, reabsorption, secretion |
| During Tubular reabsorption, apx _____ liters of filtrate are generated each day, but only ____ liter of urine is produced | 180/1 |
| Tubular secretion rids the body of excess _____, drugs and _____ | electrolytes, histamines |
| Urine is composed of | 95% H2O, urea, electrolytes and uric acid |
| The concentration of urine is regulated by what hormone? | ADH |
| The _____ extend directly from the hilum of the kidney and they move urine from the kidney to the bladder | ureters |
| The ____ is a muscular sac for temp storage of urine | bladder |

| Micturation = | Urination |
| The micturation Reflex is controlled by what part of the NS | parasympathetic |
| The voluntary and involuntary part of micturation is due to the internal and extenal | sphincters |
| Reproduction is the system specialized in | reproduction |
| The reproduction system produces ____ hormones, and these sex hormones cause developement of secondary | sex / sex charatcteristics |
| Primary Male sex organ | Testes |
| Primary Female sex organ | Ovaries |
| Spermatogenesis | sperm cell development |
| Oogenesis | egg cell development |
| Sertoli cells are involved with the manufacture of | sperm |
| Interstitial cells are involved with the manufacture of | testosterone |
| Function of the testes | produce sperm cells and male sex hormones |
| Function of the ovaries | to produce egg cells and female sex hormones |
