7
Q
the apex of the pyramid
A

major calyx
11
Q
- large cavity near the medial side of the kidney
- holds urine
A
renal pelvis
12
Q
carries urine from the renal pelvis into the urinary bladder
A
ureters
13
Q
- in the pelvic cavity against the anterior pelvic wall
- covered by a thick fibrous connective tissue
- holds urine
A
urinary bladder
14
Q
smooth muscle that makes up the wall of the bladder
A
detrusor muscle
15
Q
- tubular passageway exiting the inferior side of the bladder
- shorter in females
- carries urine
A
urethra
16
Q
- located at the start of the urethra, right at the exit of the bladder
- smooth muscle
- continuation of the detrusor muscle
A
internal urethral sphincter
17
Q
- inferior, along the length of the urethra
- skeletal muscle
A
external urethral sphincter
18
Q
come off the abdominal aorta at the same level as the superior mesenteric and enters the hilum of the kidneys
A
renal artery
19
Q
- branch off renal arteries
- course along the calyces of the kidney
A
segmental arteries
20
Q
- continuation of the segmental arteries
- course between the renal pyramids, toward the renal cortex
A
interlobar arteries
21
Q
- continuation of the interlobar arteries
- arc over the top of each renal pyramid
A
arcuate arteries
22
Q
- branch of the arcuate arteries
- raidate out into the renal cortex
A
cortical radiate arteries
23
Q
- exit the hilum
- carry blood into the inferior vena cava
- anterior to the renal artery
A
renal vein
24
Q
- inferior
- carry blood into the glomerulus
- come off the cortical radiate artery
- enters inferior side of the glomerulus
A
afferent arteriole
25
- arteriole bundle
| - receives blood from afferent arteriole
glomerulus
26
- carries blood out of the glomerulus
- superior
- carries blood into the peritubular capillaries
efferent arteriole
27
- blood vessels that surround the renal tubule
| - merge into venules
peritubular capillaries
28
tubular pathway that drains blood plasma in the glomerulus
renal tubule
29
- surrounds the glomerulus
| - collects plasma from the glomerulus (filtrate)
glomerular capsule
30
- twisted portion of renal tubule more proximal to the glomerulus
- carries fitrate into the loop of Henle
proximal convoluted tubule
31
- large, hairpin loop that carries filtrate
| - continues into the distal convoluted tubule
loop of henle
32
portion of the loop of henle that courses inferiorly
descending limb
33
portion of the loop of henle that courses superiorly
ascending limb
34
- twisted portion of the renal tubule more distal to glomerulus
- end of renal tubule
distal convoluted tubule
35
- several renal tubules merge into one.....
| - merge toward the apex of the pyramids
collecting duct
36
- receive filtrate from the collecting ducts
- located in the renal papilla
- dumps filtrate (urine now) into minor calyx
papillary duct
37
- paired organs in females
- inside pelvic cavity, lateral to both sides of the uterus
- small, round, and lumpy
ovaries
38
thick, ligamentous band that will attach the ovaries to the uterus
ovarian ligament
39
- extend from the uterus, adjacent to the ovarian ligaments
| - coursing laterally on both sides toward the ovaries
fallopian (uterine) tubes
40
- rounded, muscular organ located just posterior to the bladder
- gets smaller after menopause
- where babies grow
uterus
41
thick, ligamentous band that connects the uterus to the anterior pelvic wall on both sides
round ligament of the uterus
42
more flat, membranous ligament that attaches the lateral sides of the uterus to the lateral and posterior pelvic walls
broad ligaments
43
- located at the inferior edge of the uterus
- muscular opening to the uterus
- dip inferiorly into vaginal canal
cervix
44
- tube that will connect the 'outside' to the cervical opening
- located directly posterior to the urethra and directly anterior to the distal rectum
vagina
45
- paired organs in males
- located in scrotal sac, outside of pelvic cavity
- oval shaped organs
testes
46
- bundle of vessels, nerves, and vas deferens
| - enters testes/scrotum
spermatic cord
47
- tubular duct in the spermatic cord
- leads to epididymis attached to the testes
- leads to seminal vesicals
vas deferens
48
- rounded gland just inferior to the bladder
| - vas deferens merges with the urethra here
prostate
49
contains 3 spongy compartments and a pathway for the urethra to open to the outside
penis
