Study Notes
Endocrine System and its Function
- The endocrine system is a network of glands that produce and release hormones into the bloodstream.
- Hormones regulate various bodily functions, including growth, metabolism, and reproduction.
- Essential hormones include insulin, glucagon, adrenaline, and testosterone.
Roles of Hormones in Male and Female Reproductive Systems
- Male: Testosterone is a crucial hormone; it promotes sperm production, secondary sex characteristics (e.g., deeper voice, facial hair), and libido.
- Female: Estrogen and progesterone regulate the menstrual cycle, prepare the uterus for pregnancy, and support the development of secondary sex characteristics (e.g., breast development).
Parts of the Male Reproductive System
- Testes: Produce sperm and testosterone.
- Epididymis: Stores sperm.
- Vas deferens: Transports sperm.
- Seminal vesicles: Produce seminal fluid.
- Prostate gland: Adds fluid to semen.
- Penis: Delivers sperm.
Parts of the Female Reproductive System
- Ovaries: Produce eggs and estrogen and progesterone.
- Fallopian tubes (oviducts): Transport eggs from ovaries to uterus.
- Uterus: Houses the developing fetus.
- Cervix: Connects uterus to vagina.
- Vagina: Receives sperm and allows childbirth.
Source of Evidence of Evolution
- Fossils provide a historical record of past life forms.
- Anatomical similarities between species suggest common ancestry.
- Embryological development patterns unveil evolutionary relationships.
- Molecular biology, comparing DNA and protein sequences, supports evolutionary connections.
- Biogeography patterns show how species are distributed across the globe, influenced by evolutionary processes.
Theories of Evolution
- Natural selection: Organisms with traits better suited to their environment are more likely to survive and reproduce, passing on those advantageous traits.
- Genetic drift: Random fluctuations in gene frequencies within a population, particularly impactful in small populations.
- Mutation: Changes in DNA sequences that can introduce new traits within a population, potentially providing raw material for natural selection.
- Gene flow: The exchange of genetic material between populations through migration and interbreeding.
Biodiversity and Stability
- Biodiversity encompasses the variety of life on Earth at all levels, from genes to ecosystems.
- Biodiversity contributes to ecosystem stability by providing a variety of species that perform different functions and maintain ecosystem balance.
- Loss of biodiversity can disrupt ecosystem processes and reduce resilience to environmental changes.
