HBS Set #4- Vocabulary about the excretory and reproductive systems

TermDefinition
Excretory system Removes liquid waste from the body through the bladder. Regulates the levels of H2O (water) in the body
Urine A liquid made by the kidneys as it filters waste (urea) and extra water out of your blood
Kidney The organ in charge of filtering waste and extra water out of the blood.

Reproductive system Creates gametes (sperm and eggs) and hormones that regulate puberty (testosterone and estrogen). Allows for sexual reproduction. Allows for the growth and development of a baby through pregnancy (female only).
Gametes Cells used in sexual reproduction- they have half of a set of DNA.
Gonad An organ used to produce gametes and hormones.
Testes The male gonad-- produces sperm and testosterone
Ovaries The female gonad-- produces eggs and estrogen

Fertilization The combination of two gamete cells to create an offspring with a full set of DNA.
Internal development (pregnancy) Following fertilization, the developing offspring stays inside of the body of the mother. This is more energy intensive, but increases survival rates of the offspring.
External development (eggs) Following fertilization, the developing offspring grows outside of the body of the mother, usually in an egg shell. This is less energy intensive, but the survival chances of the offspring goes down.
Zygote The cell with a full set of DNA that is created during fertilization.
Embryo An unborn or unhatched offspring in the process of development.
Fetus A more developed offspring that has started to develop specific cells, tissues, and organs.
