Fluid outside the cell is called
Extracellular fluid
ECF
Consist of interstitial fluid, plasma, lymph fluid…
Na+ and Cl-
Fluid inside the cell is called..
Intracellular fluid ICF 25L Largest volume of fluid K+ and HPO4-
Fluid surrounding the cells called
Interstitial fluid
IF
H2O male
60%
Average male is 154lbs/70kg
H2O female
50%
H2O infant
80%
ADH does what?
- decreasing urine volume
* to increase kidney tubule reabsorption of sodium and water from tubular urine to blood
ADH is released from where?
Posterior pituitary gland
Aldosterone
- adrenal cortex/pituitary gland
- Hormone that stimulates the kidney to retain sodium ions and water
- *Increases sodium reabsorption in the kidney tubules
ANH
Atrial Natriuretic Hormone
From the atrial wall of the heart also affects urine volume
Dehydration occurs when
fluid output exceeds intake for an extended period
decrease in salivation
Which ion helps form thyroid hormones
Iodine
What is the largest volume of water in the body
Intracellular fluid
ICF
What is extracellular fluid
ECF?
Liquid fraction of whole blood called plasma
Where are the kidneys located?
Under back muscles, behind parietal peritoneum, just above waist line
What part is the medulla
Inner portion of kidney
Kidneys help regulate the concentration of what found in the blood
- Regulate levels of many chemicals
* regulate blood pressure
The cells of the juxtaglomerular apparatus help regulate what
Blood pressure regulation
Anuria
Absence of urine
Polyuria
Unusually large amount of urine
Oliguria
Scanty/few amount of urine
Glycosuria
Glucose in the urine
INternal urethral sphincter
INvoluntary
located at the bladder exit
External urethral sphincter
Voluntary
Circles the urethra just below the neck of the bladder
Waste products excreted by the kidney
Nitrogenous waste
Ammonia and urea
Location of the testes
In the scrotum/gonads
Suspended outside to reduce temperature, important for normal production and survival if the sperm
Soren cells develop where?
In the walls of the tubule and are released into the lumen and begin their journey to the exterior of the body
Seminal fluid/semen developed where?
60% seminal vesicles
30% prostrate gland
Seminiferous tubules
Fertilization occurs where
Fallopian tube
Fringe like projection
Fimbriae
Located at the end of the fellopian tubes/uterine tube
2 structures within the scrotum are
Testes and Epididymis
Seminiferous tubules produce
Sperm
Spermatozoa contains
Genetic material in the head
It’s covered by acrosome enzymes so that it can penetrate the ovum
Seminal fluid is
Seminal vesicles 60% yellowish thick secretion contains sugar for energy
Prostate gland 30% thin milk colored fluid nutrient for sperm
