Connective Tissue
Which type of connective tissue is responsible for storing energy & insulating the body?
Adipose tissue - Adipose tissue stores energy as fat and provides insulation to the body.
True / False
All epithelial tissues contain blood vessels.
False
Explanation: Epithelial tissues are avascular, meaning they do not contain blood vessels and receive nutrients through diffusion.
What tissue makes up the lungs ?
Epithelial tissue
The alveoli in the lungs are lined with epithelial tissue for gas exchange
This tissue overs body surfaces and lines organs
Epithelial tissue
_________ are the basic unit of life in all living organisms
Cells
what type of connective tissue forms the rigid structure of the skeleton?
Bone - Bone is a rigid connective tissue that forms the skeleton, providing structural support
Where would you most likely find pseudostratified columnar epithelium?
C) Lining of the trachea
Explanation: Pseudostratified columnar epithelium, often ciliated, lines the trachea and helps in moving mucus.
What tissue makes up the stomach?
Muscle tissue (smooth muscle)
The stomach is made up of smooth muscle tissue that helps churn & mix the food
This tissue supports, protects, and binds other tissues
Connective tissue
The group of cells working together to perform a similar function is called ______________
Tissue
Which connective tissue contains a network of reticular fibers & supports lymphoid organs?
Reticular connective tissue - Reticular connective tissue contains a network of reticular fibers and supports lymphoid organs like the spleen and lymph nodes.
Which type of epithelial tissue is specialized to stretch and is found in the urinary bladder?
C) Transitional
Explanation: Transitional epithelium is specialized to stretch and is found in the urinary bladder, allowing it to expand and contract.
What tissue make up the kidneys ?
Epithelial Tissue
the kidneys contain epithelial tissue in their nephrons, involved in filtration & absorption
This tissue responds to stimuli and transmits electrical impulses
Nervous tissue
The cardiovascular system is an example of an ___________
organ system
Name 4 connective tissues
1. Blood Example: Red blood cells, white blood cells, platelets in plasma
2. bone
3. hyaline cartilage Example: Cartilage in the nose, trachea, and at the ends of long bones (articular cartilage)
4. Fibrocartilage - Example: Intervertebral discs, menisci of the knee, pubic symphysis
5. dense fibrous - Example: Tendons (connecting muscle to bone), ligaments (connecting bone to bone)
6. areolar - Example: Found around blood vessels, nerves, and organs
7. adipose - Example: Fat tissue under the skin (subcutaneous fat), around kidneys, in the abdomen
8. reticular - Example: Found in lymphoid organs (lymph nodes, spleen), bone marrow
True / False
Epithelial tissues are vital for maintaining the body's homeostasis.
True
They serve as barriers protecting against environmental hazards, facilitate the absorption of essential nutrients, enable the secretion of vital substances, and participate in sensory reception.
What tissue makes up the inner ear (cochlea)?
Nervous tissue
The cochlea in the inner ear contains nervous tissue responsible for processing sound
This tissue contracts to enable movement
Muscle tissue
The smallest level of organization in the human body is the _______________
chemical level
True / False
Elastic connective tissue is found in the intervertebral discs of the spine.
False
Explanation: Elastic connective tissue is characterized by elastic fibers, not typically found in intervertebral discs. Fibrocartilage, not elastic connective tissue, is found in intervertebral discs.
Why is the ability to regenerate important for epithelial tissues? Provide an example of where this is crucial in the body.
Answer: Epithelial tissues often face wear and tear from environmental exposure, mechanical stress, and chemical damage. Their ability to regenerate quickly ensures the maintenance and repair of protective barriers, preventing infections and maintaining proper function.
Example: The skin's epidermis is a stratified squamous epithelium that continuously regenerates to replace dead cells, maintaining the skin's integrity and protective role.
What tissue makes up the spleen ?
Connective tissue
the spleen is composed largely of connective tissue involved in filtering blood & immune responses
This tissue is responsible for pumping the blood through the body
Muscle
The heart is made of muscle tissue
What is the cell organization hierarchy ?
Chemical - Cellular - Tissue - Organ - Organ system - Organism
