Unit 3 / Year 2 Flashcards
What are the 4 main types of tissues?
- Epithetical tissues = Protection, Secretion, absorption.
- Connective - Support soft body parts and bind structures together.
- Muscle - Movement
- Nervous - Conducts impulses used to help control and coordinate body activities.
What are the two different types of cells?
- Human
- Animal
What makes up the epithelial tissue?
- Simple
- Compound
What is the Cell Membrane within a human cell?
An outer coating which selectively transports substances into and out of the cells.
What is the Nucleus within a human cell?
The control centre of the cell, regulating its general and specialist functions
What are Ribosomes within a human cell?
They Manufacture other proteins that the body needs.
What are Mitochondria within a human cell?
These supply the Cell’s energy source.
What are Centrolises within a human cell?
An essential part of the Cell Division.
What are the different types of cell functions?
Respiration, Growth, Excretion, Irritability
What are Enzymes used for in a human Cell?
Enzymes are Protein Catalysts that enable metabolic reactions.
What are Empithial tissues used for in the Human Body?
It makes up the lining of the body and its organs with epithelial cells.
What are Connective tissues used for in the Human Body?
It plays a supportive structural role in the body which also includes blood.
What are Muscular tissues used for in the Human Body?
Allows for movement and also helps with circulation and digestion.
What is Nervous tissue used for in the Human Body?
Allows for electrical impulses within the body, allowing for faster transfer of information.
What are the different types of connective tissues?
Cartilage, Adipose, Areolar, Bone, Blood.
What are the 3 different types of muscle tissue?
1,) Striated = These Muscular tissues are under conscious control, they enable us to control our bones and Muscles in order to move our body.
2,) Non-Striated = These muscular tissues are generally inside the body in which we are not consciously aware off and do not have control off.
3,) Cardiac Tissue = These tissues are found within the heart and are involuntary and not within our subconscious control.
What are the different characteristics of muscle tissue?
1,) Contractibility
2,) Irritability
3,) extensibility
4,) elasticity
What does the brain do?
The brain is the centre of all neurological functions and allows the human body to function and move within daily life
What does Skin do?
A protective outer layer of the human body, protecting the body’s organs and structural stability.
What does the heart do?
A centre point of he body within the chest. Pumping blood around the body and is essential for human life.
What do the lungs do?
Located either side of the human chest and generate oxygen to be pumped around the human body.
What does the liver do?
This is part of the digestion system and helps with excretion of toxic chemicals or waste from he human body.
What does the pancreas do?
Located behind the stomach, allowing for secretion of enzymes within the digestive system.
