Unit 7: Animal Structure & Function Flashcards
Tissue Types
4
Epithelium
Connective
Muscle
Nervous
What is Epithelium (tissue)?
The thin tissue forming the outer layer of a body’s surface.
What is Connective (tissue)?
Tissue that connects, supports, binds, or separates other tissues or organs.
What is Muscle (tissue)?
A soft tissue that composes muscles in animal bodies, and gives muscles the ability to contract.
What is Nervous (tissue)?
The main tissue component of the two parts of the central nervous system(CNS); the brain and spinal cord, and the peripheral nervous system (PNS).
Integumentary System
AN ORGAN SYSTEM
that protects the body from various kinds of damage, such as loss of water or abrasion from outside.
Skeletal System
AN ORGAN SYSTEM
the framework of the body, consisting of bones and other connective tissues, which protects and supports the body tissues and internal organs.
Muscular System
AN ORGAN SYSTEM
consisting of skeletal, smooth and cardiac muscles.
Digestive System
AN ORGAN SYSTEM
that begins with the mouth then the esophagus, stomach, small intestine, and large intestine, then the rectum and anus.
Circulatory System
AN ORGAN SYSTEM
that circulates blood and lymph through the body.
Lymphatic System
AN ORGAN SYSTEM
the network of vessels through which lymph drains from the tissues into the blood.
Respiratory System
AN ORGAN SYSTEM
the set of organs that allows a person to breathe.
Urinary System
AN ORGAN SYSTEM
consists of the kidneys, ureters, bladder, and the urethra.
Nervous System
AN ORGAN SYSTEM
the network of nerve cells and fibers that transmits nerve impulses between parts of the body.
Endocrine System
AN ORGAN SYSTEM
the collection of glands that produce hormones.
Reproductive System
AN ORGAN SYSTEM
The organs and glands in the body that aid in the production of new individuals.
For males, it’s just semen.
Open-Circulatory System
Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
Closed-Circulatory System
Blood is pumped by a heart through vessels, and does not normally fill body cavities.
Sexual Reproduction
Repopulation by two individuals.
Asexual Reproduction
It only takes a single organism.
Types of Asexual Reproduction (3)
- Binary Fission
- Fragmentation
- Budding
Homologous Chromosomes
Chromosome pairs, one from each parent, that are similar in length, gene position, and centromere location.
Zygote
a DIPLOID cell resulting from the fusion of two haploid gametes.
Gamete
A mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
Haploid
Having a single set of unpaired chromosomes.
Diploid
containing two complete sets of chromosomes, one from each parent.
Circulatory Systems (3) and define
Hydra- They are small, solitary and only exist in the polyp form.
Insects- Any small air-breathing arthropod of the class Insecta.
Earthworm- A tube-shaped, segmented worm found in the phylum Annelida.
Function of Meiosis
It is the stage of the life cycle when a cell gives rise to two haploid cells (gametes) each having half as many chromosomes.
Gametes are
Haploid or Diploid????
HAPLOID MOTHER FUCKER
WHAT is formed when two gametes fuse??
Fusion
Like in sexual reproduction, the cells fuse
Advantage of sexual reproduction?
Human evolution, due to different genes forming together
Methods of birth control
Pill IUD BC shot Condom Diaphragm Cervical cap
