The Abdominal Cavity is lined by | the peritoneum |
The 6 functions of the digestive system | Ingestion, mechanical processing, secretion, digestion, absorption, and excretion |

The Kidneys __________ | Produce Urine |
The Ureter | Transports urine toward the urinary bladder |

The Urethra | Conducts urine to exterior |
Digestive and Urinary System connect ________ | to blood circulation |
Functions of the Kidneys Excretion: removal of ____ from body fluids in _________ | wastes, urine |
Regulation of blood: - Ions - control __________ -PH - control ________________ -pressure and volume - control ____________ | 1. control blood Na, K, and Cl levels 2. control blood h and hco levels 3. control blood fluid volume and thus blood pressure |
Kidneys accomplish excretion and regulation of blood by | Filtration of water, ions, nutrients and waste products from the blood. Reabsorption of most of the water, Ions and nutrients back into the blood Excretion of metabolic wastes into the urine |
We lose water constantly through our ____ _______ _____ | skin, lungs, digestive system |
The Kidneys can regulate ___________ in our bodies because they can _______ or _______ urine | water volume, concentrate, dilute |
The Kidneys are located on ______ side of the ________ and partly ______ by the _______ | either,vertebral column, protected, rib cage |
The ________ is the outer portion of the kidney | Renal cortex |
The ________ is the inner portion of kidney separated into _________ by _________ | Renal medulla, renal pyramids, renal column |
Each Kidney receives blood from a __________ | renal artery |
The Renal Artery branches into many smaller and smaller arteries which - travel between _________ within the _______ - ultimately deliver blood via ______ to a ________ ________ called glomerulus | Renal pyramids, renal columns, arteries, capillary network |
Facts about Kidneys | |
The Kidney is composed of _____ and a _____ system | nephrons, collecting system |
The Nepron is the ______ ____ of the kidney | functional unit of the kidney |
____ production begins in the nephron | urine |
_____ is filtered into the nephron | blood |
______ changes during the process | Compositon |
The Nephron is composed of _______ and ______ | renal corpuscle and renal tubule |
The Renal Corpuscle spherical structure is composed of | glomerulus, Bowman's capsule, Urinary Space |
What has a intertwining network of capillaries, receives blood from the afferent arteriole, and releases blood through the efferent arteriole | Glomerulus |
What is composed of squamous epithelial cells, has a sac like structure that surrounds the glomerulus and encloses the urinary space ( the space between the inner layer lining of the glomerulus and the outer layer of the capsule) | Bowman's Capsule |
Filtration of fluid from blood into the nephron occurs in the __________ _____ | renal corpuscle |
In the Renal corpuscle ________ _________ forces _____ and dissolved substances out of the _______ into the urinary space | blood pressure, h20, glomerulus, |
The Renal corpuscle produces a _____ ________ solution called filtrate | Protein free |
The Three Layer of Filtration | 1. The Glomerulus(capillary) : endothelial cell layer 2. middle connective tissue layer 3. inner lining of the bowman's capsule : epithelial cell layer |
In the Glomerular endothelial layer there are ____ in the _______ ______ lining the glomerular capillaries | pones, endothelial cells |
The pones in the Glomerular endothelial layer are small enough that they ____ _____ of _____ cells into the filtrate But allow some _____ through | prevent, passage, blood, protein |
The Glomerular capillaries are surrounded by ________ cells called __________ of the inner lining of the ______ ______ | Epithelial, podocytes, bowman's capsule |
The Podocyte layer is composed of many foot processes called ______ | pedicles |
_____ ______ between adjacent pedicels of _______ - smaller than the pores of the endothelial cells They only allow ____ and ______ ________ from the blood into the urinary space | Filtration slits, podocyte, h20, dissolved solutes |
Blockade of the _________ connective tissue layer induces kidney disease | Middle |
The _____ _____ layer between the pores and slits can become clogged with "debris" ! | Connective tissue |
RENAL TUBULE A long _______ ______ extending from the cortex into the medulla and _____ to the cortex | U-Shaped, tube, back |
RENAL TUBULE It begins at ____ _______ corpuscle It is composed of the ______ ________ _____ Ends at the collecting duct | renal corpuscle, Proximal convulted tubule,loop henie, DCT |
The Wall of the renal tubule is composed of _____ ______ -from ______ - to columnar - depending on the _____ of activity of that portion of the tubule | epithelial cells,squamous, degree |
Return of Filtrate from the ____ back into the blood Functions of renal tubule cells -______ from ______ - return it to the ______ - what is left in the tubule is excreted in the urine - filtrate traveling along the ________ ______ changes | Nephron, reabsorb filtrate,blood, tubule composition |
Peritubular capillaries and vasa recta The _____ ______ and ______ returns from the filtrate in the tubule to ________ via _____ _________ ____ ______ both are branches of the _______ arteriole They drain blood into the venous system and back to th | Reabsorbed h20, solutes, blood, Pertitublar capillaries, vasa recta, efferent, heart |
The PCT is the _____ segment of the ______ ________ | 1st, renal tubule |
In the Renal tubule _______ ________ of filtrate occurs 60 - 70 % of the filtrate is reabsorbed Epithelial cells have _________ to increase surface area for _____ | bulk reabsorption, microvilli, absorption |
The Loop of Henie _______ segment of the renal tubule - Composed of a: __________ ________ - fluid flows down into the medulla | middle, descending limb |
The _______ _________ fluid flows "back up" into the cortex | ascending limb |
How the loop of Henie Concentrates Urine | Na+ and Cl- are actively pumped out of the ascending limb ( and back into the bloodstream) H20 follows out of the descending limb and back into the bloodstream Tubular fluid becomes very concentrated - urea is main solute |
The DCT is the _____ segment of the renal tubule | last |
The Epithelial cells lining the DCT are ________ than those of the PCT and do not have _______ | smaller, microvilli |
The cells in the DCT are less _____ than the cells of the pct but are more ___ ______ than pct cells | active, highly specialized |
_____ _________ to the filtrate are made in the DCT | Further adjustments |
The DCT is very selective in _______ in response to __________ This regulates _______ ______ and ________ and blood ph | reabsorption, hormones, blood pressure volume |

The DCT regulates ______ & ________ | blood pressure, volume |
What happens if decreased blood pressure is sensed by the JG cells | The JG cells release renin which activates angiotensin (another hormone) |
