Question 1

What are the four Basic Tissues of the Body? ( 4 )

Answer 1

1. Epithelial
2. Connective
3. Muscle
4. Nervous

Question 2

What are the functions of Epithelial Tissue? ( 4 )

Answer 2

1. Protection
2. Absorption
3. Secretion
4. Sensation

Question 3

Describe how the Epithelial Tissue Protects…

Answer 3

Epithelial tissue lines the body’s surfaces and organs, shielding underlying tissues from physical and chemical damage, as well as from infection and injury

Question 4

Describe how the Epithelial Tissues Absorbs…

Answer 4

Epithelial tissue lining the digestive tract are designed for absorbing nutrients and water from the external environment

Question 5

Describe how the Epithelial Tissue Secretes…

Answer 5

Glandular Epithelial cells ( glands ) secrete substances like hormones, enzymes, and mucus

Question 6

Describe how the Epithelial Tissue Senses…

Answer 6

Epithelial cells in the nose, eyes, and ears are involved in detecting stimuli like odors, light and sound

Question 7

What are the functions of Connective Tissue? ( 5 )

Answer 7

1. Support and Structure
2. Connecting and Binding
3. Transporting Substances
4. Defending against Pathogens
5. Storing Energy

Question 8

Describe how the Connective Tissue Supports and maintains Structure…

Answer 8

Provides the framework for organs and tissues, giving them their shape and form ( can be rigid e.g. bone or flexible e.g. cartilage or stretchy e.g. elastic tissue ) ( Bone - Supports Skeleton, Cartilage - Cushions Joints, Ligaments and Tendons - Connect Bone and Muscle )

Question 9

Describe how the Connective Tissue Connects and Binds…

Answer 9

Acts as a bridge between different tissues and organs ( Ligaments connect bone to bone, Tendons connect muscles to bones )

Question 10

Describe how the Connective Tissue Transport Substances…

Answer 10

Blood is responsible for transporting oxygen, nutrients, hormones and waste products throughout the body. Connective tissue in other parts of the body also play a role in the diffusion of nutrients and waste between cells and blood vessels

Question 11

Describe how Connective Tissue Defends against Pathogens…

Answer 11

Immune cells defend against infection by recognising and eliminating pathogens. Inflammation is a process initiated by connective tissue, which is a defence mechanism against injury and infection

Question 12

Describe how Connective Tissue is involved in Storing Energy…

Answer 12

Adipose tissue stores fat, which serves as an energy reserve and can be used by the body when needed

Question 13

What are the functions of Muscle Tissue? ( 5 )

Answer 13

1. Movement
2. Posture and Stability
3. Energy and Metabolism Storage
4. Heat Production
5. Organ Function

Question 14

Describe how Muscle Tissue is involved in Movement…

Answer 14

Skeletal muscle tissue is responsible for voluntary movements of the body, e.g. walk and run

Question 15

Describe how Muscle Tissue is involved in Posture and Stability…

Answer 15

Muscles maintain body posture and balance. Skeletal muscles stabilise joints

Question 16

Describe how Muscle Tissue is involved in Energy Metabolism and Storage…

Answer 16

Muscle tissue is always using energy even at rest, it can store carbohydrates and amino acids for later use as fuel

Question 17

Describe how Muscle Tissue is involved in Heat Production…

Answer 17

Muscle contractions produce heat as a byproduct, which maintains body temperature in cold environments ( e.g. shivering is an involuntary muscle contraction for generating heat when body temperature drops )

Question 18

Describe how Muscle Tissue is involved in Organ Function…

Answer 18

Cardiac muscle is responsible for pumping blood and maintaining proper circulation throughout the body

Question 19

What are the Functions of Nervous Tissue? ( 3 )

Answer 19

1. Reception of general sensory information
2. Receiving and perceiving special sensations
3. Integration of sensory information

Question 20

Describe how Nervous Tissue is involved in the Reception of General Sensory Information…

Answer 20

Composed of neurons and glial cells, enables rapid transmission of electrical impulses , facilitating communication between the brain, spinal cord, and periphearl nerves

Question 21

Describe how Nervous Tissue is involved in Receiving and Perceiving special sensations…

Answer 21

Allows the body to detect and interpret external and internal stimuli, coordinates muscle movement allowing for voluntary and involuntary actions

Question 22

Describe how Nervous Tissue is involved in the Integration of Sensory Information…

Answer 22

Nervous tissue integrates and processes sensory information, enabling the brain to make decision and formulate responses
