|
Definition
| Most epithelial tissues form internal and external linings of the organs of the body. |

Term
| At what stage of life does epithilial cells form glands? |
|
Definition
| some epithelial cells form glands of the body during embryonicdevelopmen |
|
|
Term
| What does connective tissue do? |
|
Definition
| As the name implies, connective tissue binds cells and other tissues together. |
|
|
Term
| Does the body have several types of body tissues? |
|
Definition
Yes,
The body contains several types of connectivetissue, each with specific functions.
Some connective tissue consists of a loosely knit mesh of fibers and cells and is known as loose connective tissue . It serves as a packing material around cells. Fat cells are often located in this type of connec tivetissue. |
|
|
Term
| Fat cells are located in what type of tissue? |
|
Definition
|
|
Term
| When loose connective tissue contains many fat cells it is called |
|
Definition
|
|
Term
| Name two functions of fat |
|
Definition
1) Fat tissue is an important storage depot for energy.
2) provides insulation against cold |
|
|
Term
| What are macrophages and where are they located? |
|
Definition
Macrophages are is a group of cells that help guard us against bacterial infections. Their name means big eaters because the gobble up bacteria. They are located in loose connective tissue.
|
|
|
Term
| Tissue that consists primarily of densely packed fibers are called? |
|
Definition
| Dense fibrousconnective tissue , it is found in tendons and liga -ments. Ligaments are one type of dense connectivetissue. Ligaments are structures that reinforce joints.They join bones to bones at joints. Tendons are another type of dense connective tissue. They connect muscles to the bones of the body. When a muscle contracts, its tendon pulls on the bone,causing movement. |
|
|
Term
| What are the three types of Specialized connective tissue |
|
Definition
1) cartilage, bone, and blood.
Cartilage is found in many parts of the body—for example, the tip of the nose, the ears, the endsof the long bones, and between the bones of the spine.
Cartilage has no blood vessels and must benourished by nutrients that come from blood vessels surrounding this tissue. For this reason, cartilage |
|
|
Term
Cartilage has no______________ and must be________________by___________Thats why cartilage heals _________ when damaged. |
|
Definition
| 1) blood vessels and must be nourished by nutrients that come from blood vesselssurrounding this tissue. For this reason, cartilage heals very slowly, if at all, when damaged. |
|
|
Term
| Bone is another specialized connective tissue. What are the functions of bone |
|
Definition
| Bone is dynamic, living tissue that forms the internal framework of our bodies—our skeleton.Some bones provide protection to internal organs,such as the brain, heart, and lungs. Besides providing support and protecting organs, bone actsas a calcium reserve that helps us maintain proper blood calcium levels in the bloodstream. Calcium is required for many body functions, such as musclecontraction, nerve functioning, and blood clotting. |
|
|
Term
| Blood consist of _________blood cells and__________blood cells and fragments called_______________ |
|
Definition
| Blood consists of red blood cells and white blood cells and fragments called platelets . |
|
|
Term
| Red blood cells, white blood cells and platlets are suspended in fluid called |
|
Definition
|
|
Term
| What do red blood cells do |
|
Definition
| . Red blood cells transport oxygen to the cells of the body from the lungs and transport waste carbondioxide to the lungs for removal. |
|
|
Term
| What do white blood cells do |
|
Definition
| White blood cells are involved in fighting infections and cancer. |
|
|
Term
|
Definition
| Platelets play a key role in blood clotting. |
|
|
Term
| One of the four primary tissues whose name in latin is mouse. |
|
Definition
| Muscle gets its name from the Latin word for “mouse” (mus). Early observers likened the contracting muscle of the biceps to a mouse moving under a carpet |
|
|
Term
| What happens when muscles contract? |
|
Definition
| When muscle contracts, it causes body parts likethe arms and fingers to move. Working in large numbers, muscle cells can create enormous forces. |
|
|
Term
| The primary tissue that respond to stimuli |
|
Definition
| Nervous tissue consists of nerve cells, or neurons , that respond to stimuli,such as pain or temperature. Stimulation of thesecells results in tiny bioelectric impulses. Neurons |
|
|
Term
| Cells in nerveous tissue are called |
|
Definition
Neurons
Nervous tissue consists of nerve cells, or neurons |
|
|
Term
|
Definition
| Neurons respond to stimuli,such as pain or temperature. Stimulation of these cells results in tiny bioelectric impulses |
|
|
Term
|
Definition
Cardiac muscle looks a bit like skeletal muscle,but is involuntary—that is, it contracts withoutconscious control. It is found only in the walls of the heart. Smooth muscle occurs alone or in small groups.Smooth muscle cells are most often arranged in sheets in the walls of organs, such as the stomachand intestines
Smooth muscle cells in the wall of the stomach churn the food, mixing thestomach contents, and force the liquefied food intothe small intestine. Smooth muscle contractions also propel the food along the intestinal tract.Smooth muscle cells are associated with manyblood vessels. |
|
|
Term
| Is cardiac muscle voluntary or involuntary? |
|
Definition
|
|
Term
| What does bioelectric impulses do? |
|
Definition
| transmit these impulses from one region of the body to another. They help control movements and other functions. |
|
|
Term
|
Definition
| Organs are structures in the body that perform specific functions. Organs with similar function,like the heart and blood vessels, form organ systems . |
|
|
Term
| Is it possible for one organ to belong to more than one system? |
|
Definition
Yes
Some organs belongto more than one system. The pancreas, for instance, makes hormones, so is part of the endocrine system. It also produces digestive enzymes, so it is also part of the digestive system. |
