Tissue Basics
Cartilage is part of which major tissue type
connective tissue
A single layer of short, square-shaped cells would fit into which category of epithelial tissue?
cuboid epithelium
The tissue that is highly specialized for contraction and movement is
muscle tissue
This system is responsible for exchanging oxygen and carbon dioxide to control pH balance.
respiratory system
The ability of an organism to maintain a stable internal environment is called
Homeostasis
This type of tissue is responsible for protection, producing secretions (mucus) and absorption.
epithelial tissue
The matrix of blood is a liquid called
plasma
The cells of nervous tissue that conduct impulses are called
neurons
This system includes the kidney, bladder and excretes urines.
urinary system
The control of body temperature, heart rate, and the concentration of sugar in the blood are all regulated by
feedback (negative)
This type of connective tissue provides flexible structure for various parts of the body, including your nose and ears.
cartilage
Tendons and ligaments are made up of this strong type of connective tissue.
fibrous connective tissue
The type of muscular tissue that is NOT striated
smooth muscle
This system includes the nails, skin and hair. It functions to protect, control temperature and make vitamin D.
integumentary system
Desribe how childbirth represents a positive feedback. Be specific.
1. What is the stimuli/signal?
2. What is the response?
3. What stops this cycle?
1. Baby's head pushes on the cervix
2. Brain signals to release oxytocin
3. Oxytocin travels through the bloodstream to the uterus, causing contractions.
4. Baby's head pushes MORE on the cervix
5. More oxytocin releases
This type of tissue is between your skin and muscles, allowing them to move independently of each other:
loose connective tissue
This type of epithelial tissues appears to be layered but is really just one layer of cells
pseduostratified columnar
The type of muscle tissue that is located in the walls of hollow internal structures (e.g., blood vessels, airways of lungs, and the intestinal tract)
smooth muscle
These two systems control fluid balance and defend against infectious diseases
lymphatic and immune system
Give an example of a positive and negative feedback
Positive Feedback- Childbirth
Negative Feedback- Heat in your house, Fever in the body, and Blood Glucose Regulation
List the 4 main types of tissue and their general functions.
Epithelial tissue- linings and coverings, protection, secretion, absorption, senses
Connective tissue- support and protection of body organs, stores energy, and provide immunity
Nervous tissue- sense changes, conduct impulses
Muscular tissue- movement, temperature, heat
I spy, with my little eye, some cells lining the inside of the digestive tract. Their primary function is to absorb things from the digestive system, so they have foldings of the cell membrane to increase their surface area. These foldings look like cilia, but they are NOT! The foldings are actually called microvilli. What type of epithelial tissue do these cells make up?
columnar epithelial tissue
List the 3 types of muscle tissues and where in the body each is found.
skeletal - attached to bones, limbs
smooth - intestine, blood vessels
cardiac - heart
The endocrine system is responsible for producing hormones. Describe the difference between endocrine glands and exocrine glands and provide an example of each.
exocrine - secretes into ducts, gallbladder -biles, salivary
endocrine - secretes into bloodstream, pancreas -insulin, ovary, testis
Explain the two mechanism for how the body regulates body temperature for hot AND cold conditions (Ex. after excersing AND standing outside during winter). Be specific with your answer.
Overheating - sweat, dilating blood vessels so more blood reaches surface of skin to release heat to the environment.
Too cold - shivers, muscles contract to produce heat. Constrict blood vessels to conserve heat loss to environment.
