Urinary
7.13A - identify and model the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, urinary, reproductive, integumentary, nervous, immune, and endocrine systems
Fertilization
Sexual Reproduction
Fragmentation
Spore
Gamete
Trait
Genes
Asexual Reproduction
Budding
Vegetative propagation
Chromosomes
Offspring
Binary Fission
DNA
Parthenogenesis
The reproductive process that involves one parent and produces offspring identical to the parent
Asexual Reproduction
Binary Fission
A type of asexual reproduction where organisms copy their genetic information, and then divide in half to create offspring.
Budding
A type of asexual reproduction in which an offspring grows out of the parent organism
Found in the nucleus and made of DNA, contain the genetic information needed to make new cells, and carry out cell functions
Chromosomes
DNA
The genetic material found in almost all organisms. The main component of chromosomes.
Fertilization
The process that occurs when two gametes unite.
Fragmentation
A form of asexual reproduction in which a new individual arises from a fragment of the parental body.
Gamete
A sex cell that contains only half of the genetic information of other cells.
The basic physical and functional unit of heredity made up of DNA
Genes
Offspring
The progeny or descendants of a living organism.
Parthenogenisis
A form of asexual reproduction where an unfertilized egg develops into a new individual. DNA is an exact copy of the parent, but the sex of the offspring can be determined by environmental conditions.
Sexual Reproduction
The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves
Vegetative Propagation
A type of asexual reproduction in which one plant grows new plants that are genetically identical to the parent plant
Trait
A characteristic of an organism controlled by genetics
Spore
A form of asexual reproduction. A dormant, reproductive cell formed by certain organisms (fungi, some plant & some bacteria). It is thick-walled and highly resistant to survive under unfavorable conditions so that when conditions revert to being suitable it gives rise to a new individual
Homeostasis
The process by which the body maintains a stable internal environment despite external changes.
Respiratory System
the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide
Circulatory System
Circulates blood through the body. Supplies oxygen and nutrients and helps remove waste
Digestive System
Group of organs that break down food to make absorption of nutrients in the body possible
Integumentary System
Reacts to external environment. Protects the body's deeper tissues. Includes hair, skin, nails, and sweat glands
Nervous System
Functions as the control center. Coordinates all actions and reactions.
2 PartsPeripheral Nervous System Central Nervous System
Your peripheral nervous system (PNS) is that part of your nervous system that lies outside your brain and spinal cord.
Central Nervous System
The CNS has 3 main parts: BRAIN SPINAL CORD NEURONS (Nerve Cells)
Endocrine System
Series of glands that produce and secrete hormones that the body uses for a wide range of functions.
Skeletal System
Holds organs in place, provides structural support, stores minerals, makes new red blood cells. Made up of bones, ligaments, tendons, cartilage
Urinary System
Filters, collects, and removes excess fluids and wastes from the bloodstream
Reproductive System
structures vary between male and female; function is to produce offspring and continue the species.
Muscular System
allows the body to move and provides strength, balance, and warmth.
Levels of Organization
The hierarchy (order) of complex biological systems and structures
MORE INFO
13 levels of organization of life
- Subatomic particles: The smallest units of matter, such as protons, neutrons, and electrons.
- Atoms: The basic building blocks of matter, composed of subatomic particles.
- Molecules: Groups of atoms that are bonded together. Two oxygen (O) atom combines to form oxygen molecule (O2)
- Organelles: Specialized structures made up of aggregates of macromolecules within a membrane that carry out specific functions.
- Mitochondrion involved in ATP synthesis, chloroplast in photosynthesis
- Cells: The basic smallest unit of life, capable of carrying out all the basic functions of life such as growth, metabolism, reproduction etc.
- Tissues: Groups of cells that are similar in structure and function.Tissues include epithelial tissue, muscle tissue, nervous tissue etc
- Organs: Structures that are composed of multiple tissues and that work together to perform a specific function.
- Organs include brain, kidney, liver etc.
- Organ systems: Groups of organs that work together to carry out a major function of the body.
- Organ systems such as digestive system, circulatory system etc.
- Organisms: made up of organ systems that work together to perform different life functions. Individual living things, such as plants, animals, bacteria etc.
- Populations: Groups of organisms of the same species that live in the same area.
- A pride of lion with a territory or living in a specified area
- Communities: Groups of populations that interact with each other in a particular environment.
- In African savannah, there are different communities like lions, zebra, hyena etc.
- Ecosystems: Communities of organisms that interact with each other and with their physical environment.
- Ecosystems include grassland ecosystem, desert, tundra, taiga etc.
- Biosphere: The entire region of Earth that is inhabited by living things. It comprises of all ecosystems and are made up of biomes.
