Reproductive, Integumentary, + Endocrine Systems Flashcards
What is the role of the Male Reproductive System?
produce and deliver sperm
What features compose the Male Reproductive System?
testes (found in scrotum), glands, sperm ducts, urethra, penis
What is the primary Male sex hormone?
testosterone
What is the function of testosterone?
stimulates sperm production, increase body hair growth, enlargement of larynx and thickening of vocal cords, increase muscle mass, thickening of skin and bones
What is the role of the Female Reproductive System?
create ova, or egg cells, and prepare to nourish developing embryo
ovaries produce egg cells and respond to FSH + LH to begin releasing egg cells on monthly basis
What is the Female Reproductive System composed of?
Ovaries, fallopian tubes, uterus, cervix, and vagina
What are the main female sex hormones?
Estrogen, progesterone, Luteinizing Hormone (LH), Follicle Stimulating Hormon (FSH)
What is the function of the main female sex hormones?
regulate menstrual cycle, estrogen stimulates changes that occur during puberty
What is the pituatary gland’s role in relation to the reproductive system?
Controls release of FSH, LH, and oxytocin
oxytocin is important before and after childbirth
What features compose the Integumentary System?
skin, hair, nails
What is the function of the Integumentary System?
acts as a barrier and protects the body from damage, secretes waste, helps regulate body temperature + vitamin D synthesis
What are the layers of skin?
Epidermis (external), Dermis (middle), Hypodermis (internal)
dermis contains muscular tissue, follicles + hair roots, nerve endings, vessels, glands, and connective tissue
hypodermis contains body fat
What is the Integumentary System’s role in homeostasis?
regulates body temp by either narrowing blood vessels in the dermis to prevent heat loss or widening them to increase heat loss
i.e. sweat
What features compost the Endocrine System?
glands throughout the body that secrete hormones into the bloodstream
brain: hypothalamus, pineal gland, pituatary
throat: thymus, thyroid, parathyroid
pancreas aids in digestion
adrenal glands control stress responses
ovaries, testes
What is the function of the Endocrine System?
hormones travel through the circulatory system to work on particular target organs in the body
help regulate many different bodily functions such as growth + development, reproduction, stress responses, metabolism
What does the adrenal gland produce?
Adrenaline, noradrenaline, and dopamine
What is the Endocrine System’s role in homeostasis?
hormones are released in response to the body’s internal conditions and external environment
Negative Feedback Mechanism?
Senses imbalances in the body and stimulate hormone production until balance is restored
Positive Feedback Loop?
can occur during certain events that need steady increase in activity to achieve result
- product of reaction leads to increase in that reaction
(oxytocin during childbirth)
What is the Endocrine System’s relationship with CNS?
CNS senses changes in environment and endocrine system responds by releasing hormones to regulate the necessary processes
