Question Answer
Epithelial Tissue tightly packed sheets of cells that cover surfaces and line body cavities
Epithelial Tissue act as barriers to the movement of fluids and harmful microbes
Epithelial Tissue cells are joined by specialized junctions that hold them tightly tog
Connective tissueconsists of cells suspended in an extracellular matrix
Connective tissueconnects other tissues.
Loose connective tissueconnective tissue most common found throughout your body
Dense or fibrous connective tissueconnective tissue found in tendons and ligaments
Specialized forms include adipose tissue —body fat— bone, cartilage, and blood, in which the extracellular matrix is a liquid called plasma.
Muscle tissueresponsible for locomotion and keeping body upright
Muscle fibersOther term for muscle tissue
Muscle tissuecontain the proteins actin and myosin, which allow them to contract.
(1) skeletal muscle, (2) cardiac muscle, and (3) smooth musclethree main types of muscle
Skeletal musclealso called as striate or stripe muscle
Skeletal muscleattached to bones by tendons, and it allows you to consciously control your movements
Cardiac musclefound only in the walls of the heart
Cardiac musclestriated & not under voluntary control
Cardiac muscle•individual fibers are connected by structures called intercalated disks, which allow them to contract in sync.
Smooth Muscleound in the walls of blood vessels, as well as in the walls of the digestive tract, the uterus, the urinary bladder, and various other internal structures
Smooth Musclenot striated & involuntary
Nervous tissueinvolved in sensing stimuli—transmitting information
(1) neurons, (2) glial2 main types of cells
Neuronsgenerate electrical signals called conducted nerve impulse
Glialsupport neuronal function
(1) Digestion, (2) Respiration, (3) Circulation, (4) Conduction of nerve impulses, (5) Support, (6) Excretion, (7) Reproduction(7) Body Systems are specialized to carry out different tasks which are
Organsmade up of two or more types of tissue organized to serve a particular function
Organ systemsOrgans are grouped into ____________.
Organshey work together to carry out a particular function for the organism.
(1) Integumentary, (2) Skeletal, (3) Reproductive, (4) Respiratory, (5) Digestive, (6) Endocrine, (7) Muscular, (8) Cardiovascular, (9) Urinary, (10) Nervous, (11) Lymphatic11 Different Organ System
DigestionObtain energy & nutrients
RespirationExchange oxygen and carbon dioxide gases
CirculationTransport oxygen and nutrients to the other parts of the body
Open & Closed 2 types of circulatory systems
Open circulatory system heart pumps oxygen thru series of vessels and dumped in body cavity
Closed circulatory system heart pumps blood thru system of blood vessels
MEASURING PULSE RATEWhen you feel your pulse, count the number of beats in 15 seconds. Multiply this number by 4 to calculate your beats a minute.
What's a normal resting heart rate?adults ranges from 60 to 100 beats a minute.
ExcretionRemoval of wastes from cellular metabolism
SkeletalProvide a framework that supports the body.
Conduction of nerve impulses Coordinate the activities in an animal’s body and allow animal to sense and respond to environment.
Endocrine Systemto control growth, development, metabolism and reproduction through the production and secretion of hormones
The Muscular Systemworks with the skeletal and nervous system to produce movement, also helps to circulate blood through the human body
Lymphatic Systemremove infectious diseases and other pathogens from the human body
Integumentary System •consists of the skin, hair, nails, glands, and nerves
Integumentary System act as a barrier to protect the body from the outside world
Reproductionproduce offspring to ensure that the species survives
Asexual & Sexual2 types of reproduction
Asexual Reproduction does not involve fusion of two gametes.
Sexual Reproduction a new individual is formed by the union of a male and female gamete
External & Internal two types of fertilization
Gastro vascular cavity a digestive cavity with only one opening.
Mouth & AnusMore complex animals, like us, have a digestive tract with two openings which are the ___________
DiffusionIn simple animals like jellyfish gasses are exchanged directly with their environment through ________
600There are ____ skeletal muscles in the body
Skinalso called the integumentary system
Skin is the body’s first line of defense
White Blood Cellsrecognize disease agents (antigens) and create antibodies to tag and remove these antigens
Phagocytesthe white blood cell type that actually eats and destroys these antigens
Lymph Nodeshelp restore fluid lost by the blood and return it to the circulatory system
