Endocrine, Reproduction, Immune Flashcards
What makes up the endocrine system?
Glands that release their products into the blood system. These products deliver messages throughout the body
Pancreas
Maintains blood sugar levels and diabetes mellitus
Major endocrine glands
Pituitary, Hypothalamus, Thyroid, Parathyroid, Adrenal, Pancreas, Reproductive
Exocrine Gland
Releases their hormones through (tubelike structures) ducts directly to the organ that uses them
Endocrine Gland
Releases hormones directly into the blood system
Steroid Hormones
- Crosses cell membranes easily
- Passing directly into the Cytoplasm and even into the nucli of target cells
Non Steroid
Cannot pass through cell membrane of their target cells
What is a thermostat a good example of?
Mechanical Inhibition
Gamates
- Germ cell
- Able to unite with another cell of the opposition sex in reproduction to form a zygote
Major function of the male reproductive system
To produce and deliver sperm
Major function of the female reproductive system
- Produce ova
- Prepares female body to nourish a developing embryo
Where does fertilization occur?
Fallopian Tube
Fertilization
Fusion of male and female gametes to form a zygote
Placenta
Embryos organ of respiration, nourishment, and exrection
What are diseases caused by?
Any change other than injury that disrupts the normal functions of the body
Inflammatory Response
Nonspecific defense reaction to tissue damage caused by injury or infection
Active Immunity
Immunity produced by exposure to an antigen as a result of the immune system
Passive Immunity
Caused when antibodies produced by other animals for a pathogen are injected into body
Prostaglandins
- Small hormone like structures
- not produced by red blood cells
Hypothalamus
Controls the secretions of the pituitary gland
Thyroid Gland
Regulates body temperature
Parathyroid Glands
Maintains homeostasis of calcium levels in the blood
Adrenal Glands
Release hormones that help the body prepare and deal with stress
Luteal Phase
Begins after egg is released
Follicular Phase
Begins when the level of estrogen in the blood is relatively low
Zygote
Fertilized egg
Adolescence
Begins with puberty and ends with adulthood
Pathogens
Disease causing agents
Humoral Immunity
B cells provide immunity against antigens and pathogens in the body fluids
Cell Mediated Immunity
T cells provide a defense against abnormal cells and pathogens inside living cells
