What are the four Basic Tissues of the Body? ( 4 )
- Epithelial
- Connective
- Muscle
- Nervous
What are the functions of Epithelial Tissue? ( 4 )
- Protection
- Absorption
- Secretion
- Sensation
Describe how the Epithelial Tissue Protects…
Epithelial tissue lines the body’s surfaces and organs, shielding underlying tissues from physical and chemical damage, as well as from infection and injury
Describe how the Epithelial Tissues Absorbs…
Epithelial tissue lining the digestive tract are designed for absorbing nutrients and water from the external environment
Describe how the Epithelial Tissue Secretes…
Glandular Epithelial cells ( glands ) secrete substances like hormones, enzymes, and mucus
Describe how the Epithelial Tissue Senses…
Epithelial cells in the nose, eyes, and ears are involved in detecting stimuli like odors, light and sound
What are the functions of Connective Tissue? ( 5 )
- Support and Structure
- Connecting and Binding
- Transporting Substances
- Defending against Pathogens
- Storing Energy
Describe how the Connective Tissue Supports and maintains Structure…
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 )
Describe how the Connective Tissue Connects and Binds…
Acts as a bridge between different tissues and organs ( Ligaments connect bone to bone, Tendons connect muscles to bones )
Describe how the Connective Tissue Transport Substances…
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
Describe how Connective Tissue Defends against Pathogens…
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
Describe how Connective Tissue is involved in Storing Energy…
Adipose tissue stores fat, which serves as an energy reserve and can be used by the body when needed
What are the functions of Muscle Tissue? ( 5 )
- Movement
- Posture and Stability
- Energy and Metabolism Storage
- Heat Production
- Organ Function
Describe how Muscle Tissue is involved in Movement…
Skeletal muscle tissue is responsible for voluntary movements of the body, e.g. walk and run
Describe how Muscle Tissue is involved in Posture and Stability…
Muscles maintain body posture and balance. Skeletal muscles stabilise joints
Describe how Muscle Tissue is involved in Energy Metabolism and Storage…
Muscle tissue is always using energy even at rest, it can store carbohydrates and amino acids for later use as fuel
Describe how Muscle Tissue is involved in Heat Production…
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 )
Describe how Muscle Tissue is involved in Organ Function…
Cardiac muscle is responsible for pumping blood and maintaining proper circulation throughout the body
What are the Functions of Nervous Tissue? ( 3 )
- Reception of general sensory information
- Receiving and perceiving special sensations
- Integration of sensory information
Describe how Nervous Tissue is involved in the Reception of General Sensory Information…
Composed of neurons and glial cells, enables rapid transmission of electrical impulses , facilitating communication between the brain, spinal cord, and periphearl nerves
Describe how Nervous Tissue is involved in Receiving and Perceiving special sensations…
Allows the body to detect and interpret external and internal stimuli, coordinates muscle movement allowing for voluntary and involuntary actions
Describe how Nervous Tissue is involved in the Integration of Sensory Information…
Nervous tissue integrates and processes sensory information, enabling the brain to make decision and formulate responses
