human systems Flashcards
What are the 11 main human systems?
Respiratory, Digestive, Muscular, Skeletal, Circulatory, Nervous, Reproductive, Urinary/Excretory, Lymphatic/Immune, Endocrine and Integumentary
What is the Respiratory Systems main function?
To exchange gases throughout the body in order for it to function properly. i.e move fresh air into your body whilst getting rid of waste gases
What is the respiratory system made up into?
The upper and lower respiratory system.
What makes up the upper respiratory system?
The major structures are the nose/nostrils, the nasal cavities, the mouth, the throat (pharynx) and the voice box (larynx)
What makes up the lower respiratory tract?
The major structures are the windpipe (trachea) and ,within the lungs, the bronchi, the bronchioles and the alveoli
What is the process the respiratory system carries out?
The nasal passages take in air and it travels through the trachea then the bronchi brings air into the lungs where a gas exchange happens.
What is the digestive system?
The digestive system is what breaks down your food into tiny particles that can be absorbed into the blood. these particles provide energy to the body to be able to grow, repair and remain healthy. Whatever food cannot be broken down gets released from the body as faeces.
What are the 6 steps of digestion?
The six steps of digestion in order are- ingestion, propulsion, mechanical breakdown, chemical digestion, absorption and elimination.
What are the twelve main structures and organs involved in the digestive system?
The mouth, salivary glands, oesophagus, stomach, pancreas, liver, gall bladder, small intestine -duodenum and ileum, large intestine - colon, rectum and anus.
What are the 11 main functions of the muscular system?
- mobility
- stability
- posture-using the skeletal muscles
- circulation- mainly using the heart and smooth
- muscle respiration- using the diaphragm muscle
- digestion- uses smooth and lower and upper stomach muscle
- urination- compromises both smooth and skeletal muscles
- childbirth- smooth muscles in the uterus and the pelvic floor muscles
- vision- six skeletal muscles around the eye
- organ protection- muscles in the torso
- temperature regulation- skeletal muscle and muscles in the blood vessels
How many major muscles are there in the human body?
600
What are the three types of muscle tissue?
skeletal muscle, smooth muscle and cardiac muscle
Where is a place you could find smooth muscle?
In the walls of hollow organs i.e. intestines, uterus and stomach and, also, in the walls of hollow passageways including, the arteries and veins of the cardiovascular system.
what are skeletal muscles?
Muscles that connect to your bones and allow you to preform a wide range of functions and movements and make up 30-40% of your body mass. They are voluntary muscles and get controlled through nerves in your somatic nervous system sending signals to them to get them to function.
Where would you find skeletal muscle?
All throughout your body, in-between bones.
Where would you find cardiac muscle?
In your heart.
What do cardiac muscles do?
They help your heart pump blood throughout your whole body. They are involuntary muscles that your autonomic nervous system controls.
How many bones does your body contain?
206
