Question | Answer |
---|---|
Urine is stored in | The bladder |
During an erection the erectile tissue of a penis fills with | blood |
The hormone of ovulation | LH |
Muscle in the urinary bladder wall | Detrusor |
Fundus, Body, and cervix are all parts of the | Uterus |
Number of functional sperm cells created from one primary spermatocyte (precursor cell) during spermatogenesis | Four |
Urine is produced in the | Kidney |
The removal of urine from the body is called | Micturition |
From the kidneys, urine travels to the urinary bladder via the | Ureters |
Renal pyramids are located in the | Renal Medulla |
Indention of the kidney where blood vessels and ureter enter and exit | Hilum |
Most water intake occurs through | Drinking beverages |
From the urinary bladder, urine travels outside via the | Urethra |
Causes the appearance of most male secondary sex characteristics | Testosterone |
Functional unit of the kidney | Nephron |
Sex cells divide through a process called mitosis, PMAT only occurs once and each cell has a total of 46 chromosomes | False |
Site of most water and sodium reabsorption | Convoluted tubule |
Organ in females that is homologous to the testes in males | Ovary |
The process during sperm and egg creation which involves reducing the number of chromosomes by half | Meiosis |
Pouch-like organ that stores the testes and adjusts their proximity to the body based on temperature | Scrotum |
The enzyme released by the sperm head to help with oocyte penetration | hyaluronidase se |
Where does fertilization occur in the female productive tract? | Fallopian tube |
The passageway for both urine and semen in males | Urethra |
Outermost portion of the kidney | Cortex |
Number of function cells created from one primary oocyte during oogenesis | One |
The majority of the nephrons are located in the medulla of the kidney | False |
Connects epididymis to ejaculatory duct | Vas deferens |
Upon dehydration, receptors in the hypothalamus often trigger | Thirst |
When the testes fail to drop this condition is considered | Cryptorchidism |
Change in life when a women no longer produces ova, estrogen, or progesterone. | Menopause |
Most water output occurs through | Urine |
Structure inside the testis that makes sperm cells | Seminiferous tubule |
Each kidney works to it's full potential | False |
Innermost portion of the kidney | medulla |
Complete; through | Dia |
Hernia; tumor; cyst | Cele |
Drooping down | ptosis |
Bladder | cysto |
Renal pelvis | pyelo |
Surgical fixation | pexy |
Glomerulus | Glomerulo |
External opening of the urethra | Meatus |
What are gonads? | Gonads are the medical term for sex glands. |
What do gonads produce in men? | The male sex gonad is testis they produce testosterone and androgens. (little estrogen less than woman) |
What do gonads produce in females? | Female sex gonads are ovaries the produce egg, estrogen and progesterone. (Lower testosterone than man) |
List the steps in sperm penetration of the egg/ fertilization. | -Sperm travels to the Fallopian tube & locates the egg. -sperm head releases enzyme called hyaluronidase -sperm chips away the epithelial cells & fall off -sperm penetrates the plasma membrane -nuclei of sperm and egg fuse resulting in fertilization. |
What role does hyaluronidase play in sperm penetration? | It's an enzyme that helps sperm penetrate the epithelial layer around the egg wall. |
What is Cryptorchidism and what happens if left untreated? | If the testes do not descend into the scrotum they cannot produce sperm cells because the temperature in the abdominal cavity is too high. If left untreated, the cells that normally produce sperm cells degenerate, causing infertility |
List to describe the three processes in Urine Formation? | Filtration: of fluid from the fenestrated glomerular capillaries. Reabsorption: pumping useful substance from urine to the blood Secretion: pumping waste from blood into urine |
What is the process of flow for Urine? | Urine produced in the kidneys passes through the ureters, collects in the bladder, and is then excreted through the urethra. |
What is Menstruation? What age does it begin? How often does it occur? | Characterized by regular, recurring changes in the endometrium of the uterus, which culminates in menstrual bleeding. This begins ab age 13- 50s. The uterus sheds the unfertilized egg & the uterine lining. The process starts over. It occurs every 28 days |
What is the first period called? | Menarche |
What is menopause? | 1 year no period typically happens at ages 45 to 55 years old. |
Where is the prostate gland located? | It surrounds the neck of the bladder. |
What does the prostate release? | A musky, milky white, alkaline fluid. |
What does the prostate do? | It contracts during an erection blocking the pathway of urine allowing semen to pass. |
What do shift changes interrupt? | Homeostasis |
What is micturition? | Urine leaving the bladder. |
What is the bladder capacity? | The bladder holds 600mL, but you desire 150mL and the bladder is considered full at 300mL. |
What is the first step of Urine Formation? | Filtration of fluid from the fenestrated glomerular capillaries |
What is the process of flow for Urine? | Urine produced in the kidneys passes through the ureters, collects in the bladder, then excreted through the urethra. |
What two types of buffer systems are used to maintain the PH concentration of body? | Chemical and physiological buffer systems |
Describe the difference between acidosis and alkalosis and give the PH range for each. | Acidosis- accumulation of acids or loss of bases. PH below 7.35 Alkalosis- results from a loss of acids or accumulation of bases. PH above 7.45 |
