State the basic functions of the four different types of tissues
|
epithelial are tightly packed sheets of cells that cover and line organs, vessels, and body cavities, Connective Tissues are loosely organized tissues that bind organs and tissues together. Muscle tissues consist of bundles of long, thing, cylindrical muscle fibers that are able to contract, Nervous Tissue is composed mainly of neurons that can conduct and transmit electrical impulses
|
|
What are the differences between the six separate types of connective tissue
|
Loose CT, Adipose, Blood, Fibrous CT, Cartilage, and Bone tissues are composed of different cell types, each embedded in a matrix with unique composition
|
|
Epithelia..A: are loosely packed tissues that hold organs in placeB: can be free-floating tissues such as bloodC: line organs and cavities and have on surface exposedD: include the tissue that holds joint together
|
C: Line organs and cavities and have on surface exposed
|
|
Muscle tissues...A:contain actin and myosin whether or not they are striatedB: that facilitate movements requiring conscious thought are involuntaryC: increase in cell number with exerciseD: in the heart are smooth
|
A: Contain actin and myosin whether or not they are striated

|
A: storing bile

|
D:mouth>pharynx>stomach>small intestine> large intestine

|
Bile..A: is stored in the pancreasB: helps break down glycogenC: emulsifies fatD: removes water from indigestible materials in the LI
|
C: emulsifies fat

|
What are the major differences between the three types of Muscle Tissues
|
Cardiac: found in heart, involuntary, striated, forms contractions that produce a heart beat to pump blood
Skeletal: attach to bone, produces movement of body parts, voluntary, exercise increases size of cells (not number), striated Smooth: involuntary, and not striated, found in blood vessels and internal organs (DS) |
|
When a room is set at 70 degrees, and the current temperature drops below that, the thermostat turns on the heat until it is back up to room temperature, and then turns off again.
|
Negative Feedback

|
During labor hormones cause the muscles of the uterus to contract, pushing the baby out of the mother, the uterine contractions stimulate the release of more hormones, which cause the contractions to intensify in rate and duration. This inturn causes even more hormones to be released and even longer contractions.

Discuss the ethics in organ transplantation
|
Brain injury- donor would be placed on respirator to maintain oxygen flow to the organs, a suitable recipient is found through a database
cardiac deaths- can donate only tissue because lack of oxygen can cause organs to deteriorate both must have the same blood type and other markers |
|
This tissue is composed mainly of cells called neurons that can conduct and transmit electrical impulses. The main function is to help the body sense stimuli, process stimuli, and transmit to and form the brain out to the rest of the body. found in brain, spinal cord and nerves

Nervous tissue

A) organs - organ systems - tissues - cells - organism B) tissues - cells - organs - organ systems - organism C) cells - tissues - organs - organ systems - organism D) cells - tissues - organ systems - organs - organism |
C) cells - tissues - organs - organ systems - organism
