Reproductive Systems Flashcards
Functions of the Reproductive System
- Production of gametes (egg, sperm)
- Secretion of sex hormones
- Production of Offspring
- Nurturing of offspring (females produce milk)
Gonads
primary sex organs
- produce gametes and sex hormones
- make- testes
- female- ovaries
Accessory Reproductive Organs
- Ducts
- Glands
- Supporting Structures
Male Reproductive System consists of
- male gonads- testes
- accessory reproductive organs:
- Ducts- transport, storage, maturation of sperm
- Glands- secrete seminal fluid
- Supporting Structures- Penis, Scrotum
3 kinds of cells are present in the Testes
Seminiferous Tubules are made of:
a. Spermatogenic cells- develop into sperm (produce gametes)
b. Sertoli cells- provide nutrients
Leydig cells- produce testosterone
Seminiferous Tubules are made of
a. Spermatogenic cells- develop into sperm (produce gametes)
b. Sertoli cells- provide nutrients
these cells are present in the Testes
Leydig Cells
present in the Testes
-produce testosterone
Accessory Reproductive organs of the Male Reproductive System: Ducts
Ducts of the male reproductive system deliver sperm from testes to outside the body
- Epididymus
- Vas Deferens
- Ejaculatory Duct
- Urethra
Accessory Reproductive organs of the Male Reproductive System: Glands
Glands secrete seminal fluid into ducts during ejaculation
- Seminal Vesicles
- Prostate Gland
- Bulbourethral Glands
Accessory Reproductive Organs of the Male Reproductive System: Supporting Structures
- Penis
2. Scrotum (covers testes + epididymus)
Spermatogenesis
-process of sperm production
-takes place in seminiferous tubules
Meiosis & Spermiogenesis
Diploid (2n)
having 2 sets of chromosomes
-body cells are diploid
Haploid (n)
having 1 set of chromosomes
-gametes are haploid
Meiosis
cell division that produces haploid gametes
-primary spermatocyte (2n)—> spermatids (n)
Spermiogenesis
Spermatids (n)—> sperm (n)
