26
Usual site of fertilization
Fallopian tube
27
Primary female reproductive organ/gonad
Ovary
28
Structure that houses the developing fetus
Uterus
29
These move and create a fluid like current which draws an ovulated egg into the fallopian tube
Fimbriae
30
This innermost lining of the uterus sheds monthly
Endometrium
31
Middle lining of the uterus forcefully contracts during childbirth
Myometrium
32
This follicular structure forms immediately post ovulation
Corpus luteum
33
What are the main functions of the urinary system?
eliminate wastes from the body, regulate blood volume and pressure, control levels of electrolytes and metabolites, and regulate blood pH.
34
What are the size shape and location of a kidney?
They are about the size of a fist, bean shaped and located by the ribs outside of the peritoneum
35
Starting at the aorta trace the blood flow through the kidneys and back to inferior vena cava
Descending aorta, renal artery, segmental artery, interlobar artery, arcuate artery, cortical radiate artery, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries or vasa recta capillaries, cortical radiate vein, arcuate vein, interlobar vein, renal vein, inferior vena cava
36
What are the two main parts of a nephron?
Renal corpuscle and renal tubule
37
What are the four sections of the renal tubule?
Proximal convoluted tubule loop of Henle distal convoluted tubule collecting duct
38
What are the two capillary beds associated with the nephron and where are they located in relation to the glomerulus
The peritubular capillaries surround the proximal and distal tubules while the vasa cava capillaries intertwine with the loop of Henle
39
What two things make up the juxtaglomerular apparatus
Macula densa and juxtaglomerular cells
40
Describe the steps of urine formation
1. Glomerular filtration: water and solutes smaller than proteins are forced through capillary walls and into the renal tubule 2. Tubular reabsorption: water, glucose, and amino acids are transported out of the filtrate and into the Tubule cells and then enter the capillary blood. 3. Tubular secretion: hydrogen potassium Creatinine And drugs are removed from the peritubular Blood and secreted by tubule cells into the filtrate
41
Describe the basics of the renin-angiotensin-aldosterone system and its effects on blood pressure and urine volume.
–Mediated by the juxtaglomerular (JG) apparatus of the renal tubules. When cells of the JG apparatus are stimulated by low blood pressure, the enzyme renin is released into blood. Renin catalyzes a reaction that ultimately produces angiotension II. Angiotension II causes vasconstriction and aldosterone release. Result is increase in blood volume and blood pressure
42
What are the major nitrogenous waste products that are found in the urine?
Urea, uric acid, ammonia, creatinine
43
What are some of the substances not normally found in urine?
Proteins, glucose, nitrite, ketones, hemoglobin
44
What are the 4 layers of the bladder wall?
Mucosa, submucosa, muscularis, serosa
45
What type of cells make up the bladder mucosa and what is special about these cells?
Transitional epithelium appear cuboidal when relaxed and simple squamous (flat) when stretched thin
46
Describe the structure and function of the urethral sphincters.
The internal urethral sphincter is composed of smooth muscle and regulates involuntary control of urinary flow from the bladder to the urethra, while the external urethral sphincter provides voluntary regulation
47
What are the gonads and gametes of the male and female reproductive tracts?
Gonads are the testes/ovaries and gametes are the sperm/ovum
48
Describe the flow of sperm from production to ejaculation
Sperm is produced in the seminiferous tubules and then gathers in the rate testis before being stored and matured in the epididymis. Then upon ejaculation it flows through the ductus deferens and out the ejaculatory duct, mixes with semen coming out of the seminal vesicle, through the prostate, and out the urethra.
49
What is the function of the prostate gland
produce the fluid that nourishes and transports sperm (seminal fluid)
50
What is the purpose of the seminal vesicles
store and produce the majority of the fluid that makes up semen.
51
What is the purpose of the bulbourethral gland
They produce a mucus that neutralizes the acidity of the vagina so sperm can survive
52
Starting with the sperm stem cell, name the cells at the different stages of sperm development.
Spermatagonia copy to make primary spermatocytes, those divide to make secondary spermatocytes, then those divide to make spermatids which mature into sperm. The copies (diploids) have 46 chromosomes and the divided cells (haploids) have 23.
53
What are the roles of LH and FSH in the male reproductive system?
FSH stimulates the production of sperm and LH stimulates the production of testosterone
54
Where is testosterone made and what is its major role in males?
It is produced in the testes and triggers the development of internal/external sex organs as well as regulate sex drive (libido), bone mass, fat distribution, muscle mass and strength, and the production of red blood cells and sperm
55
Starting with the stem cell, name the cells at the different stages of ova development.
Oogonia are stem cells present in a fetus. They develop into primary oocytes before birth and are inactive until puberty. Primary oocytes mature and produce secondary oocytes which are shed each month. The ova is the secondary oocytes that is actually ovulated. Primary oocytes are diploid cells and have 46 chromosomes while secondary oocytes are haploid and have 23 chromosomes. The fertilized egg has 46 chromosomes because it is the combo from oocyte and sperm
56
Name the major functions of estrogen and progesterone in the female
Progesterone creates a healthy uterine lining to support a fertilized egg, embryo and fetus. Estrogen regulates the growth, development, and physiology of the human reproductive system. This hormone also influences neuroendocrine, skeletal, adipose, and cardiovascular systems. Estrogen is an important sex hormone produced primarily by the ovaries.
57
Describe the development of the follicle in the ovary, include the names of the different stages of follicle development. What are the roles of LH and FSH in this process?
Primary follicle—contains an immature oocyte vesicular follicle—growing follicle with a maturing oocyte Ovulation—when the egg is mature, the follicle ruptures; occurs about every 28 days The ruptured follicle is transformed into a corpus luteum LH and FSH stimulate this process
58
Define zygote
fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm)
59
Define morula
an embryo at an early stage of embryonic development, consisting of approximately 8–32 cells
60
Define blastocyst
a cluster of dividing cells made by a fertilized egg. It's the early stage of an embryo. A blastocyst is one step among many that lead to a pregnancy. A blastocyst forms about five to six days after a sperm fertilizes an egg.
61
Define embryo
An unborn offspring in the process of development, usually referred to as such until about 8 weeks
62
Define fetus
Unborn Offspring that is in the process of development, referred to as such from about 8 weeks to birth
