Reproductive system

1.a)Testes-located in the scrotrum , site of sperm reproduction and has seminiferous tubules where sperm are produced from.
b)Seminiferous tubules & intestitial cell- produces sprems in the testes and the cells produce testosterone are produced.
c)epididymis -it stores sperms, in the testes.
d)Vas deferens- from the epididymis to the urethrea helps the sperm travles and stores.
e)prostate gland-it secretes basic fluid and enhances sprem mobility.
f)\cowpers gland-helps in lubricatiuon by producing mucus.
g)seminal vesicles-provides energy for sperm by prducing fructose.
h) penis-it cindcuts the semesn to the vgina durind sexual intercourse.
i)urethra-joins the vas deferens with the penis, to help transport the semen.


2.The semen travels from the seminiferous tubules in the testes to the epididymis and then enters the vas deferens , the sperm then enters the urethra which connecs to the penis. during this process the sperms develops and is ready to be fretilized.

3)Seminal fliuds contains the seminle vesicle that sectres fructose that supplies energy for the sperm, the prostate gland that excretes base and enhances sperm mobility and the cowpers gland that produces mucus for lubrication.

4)The  tailr helps the sperm move and is a flagella , the midpiece has mitochindria that provides energy for the sperm, the head protects the DNA (haploid) within it and the acrosome covers the head that has digestive enzymes which penetrates the egggs shell.

5)The testosterone is the male sex hormone that is necessary for sperm production , and secondary sex characteristice(voice deeper, pubic hair, muscular development)>

6)The endocrine system triggers the GnHR(gonadotropin releasing hormone) whick targets the anterior pituitory secreting LH(leutron hormone ) and FHS(follicle stimulating hormone, which are responsible to produce testosterone.

7) a)ovaries- are the organs that develop the follicle, produce egg and hormone production.
b)follicles and corpus luteum-follicle produce estrogen and rebuild and thickens endometritium, corpus luteum thickens the endometrium and releases mucus as progeterone releases.
c)oviducts(fallopiab tube)- propels the egg towqrads the uterus where it gets fertilized.
d)uterus-where the egg is fertilized and the embyo is developed if fertilized or gets shed every month as mensruation.
e)cervix-entrance to the uterus and hold the baby.
f)vagina-its the exit for menstruation, receptable for penis and the canal where the baby comes out of while giving birth.
g)clitoris-erectile tissue , similar to penis and has many nerve endings.

8)Estrogen is the female sex hormone produced by the follicle that atrgets the uterus and thickens the endometrium , also responsible for sencondary sex characteristics ( puberty hair, breast development, body fat deposition).

9)In the ovarian cycle, the follicle develops and the egg is released with hormone production inside the ovary. In the uterine cycle. there are three phages. Menstrual phase, the endometrium is broken down and discharged,The proliferation phase where the endometrium is rebuilt and thickened . And the secretory phase where the endo metrium doubles in thickness and mucus is secreted.

10)In the ovarian cycle,the FHS( follicle stimulating hormome) triggers the ovary to develop the development of the follicle. In the uterine cycle, the LH (luteal hormone) releases progesterone and estrogen hormone. In the menstrual phase, the hormone decreases and the endometrium breaks down.In the proliferation phase, estrogne hormone increases and the endometrium rebuilds and thickens. In the secretory phase, prgesterone is produced and the endometrium doubles in thickness and mucus is secreted,

11)Oxytocin is the hormone that targets the uterus and mammary galnds. It helps the uterus contract during childbirth , so more oxytoxin equals more contraction.And also triggers release of milk , so more suckling equals more milk.

12)After implantation occurs, the hormone HCG(human chronic gonadtruim is released.This maintains the level of progesteron and estrogen which tells the interior pitutary not to produce FHS( no follicle development) , also released in the urine and also maintains the endometruim lining,
