Cells And Systems GO 3 Flashcards
What organs are in the digestive system? And what do they do
Stomach-store food and disgust food
Liver-produces bike and breaks down fat
pancreas- secretes enzymes to the small intestine
gall bladder-stores bile and breaks down starches
mouth-break down food
esophagus- push food to stomach ( peristalsis is the pushing at the muscle through vill&mircovilli
large intestine- disgust, absorbs water,Birman and minteruals forms leftover food into feces sends to the rectum
small instentine- sew creates enzymes aborses nutrients
rectum and anus
Appendix- use unknown
What’s the function of the digestive system
To disgust food and get the proteins and nutrients out of them
Two different types of digestion
Mechinal digestion- physical breakdown of food into very small pieces
Chemical digestion- breakdown of large particles into smaller particles by enzymes
The three types of energy
Carbohydrates
Liqid
Proteins
Specialized cells in the nervous system
Neurona are the specialized cell in the nervous system. The neurons job is to send and receive messages through small branches called dendrites
Nervous tissue
The nervous system Is made up of one type of tissue called the nervous tissue.
Nerves in the peripheral nervous system
2 types of neurons, sensory and Moter. Sensory neurons carry information to the central nervous system(brain) and the mother carry information from the central nervous system to the muscles and neurons
Centre nervous system
Central nervous system consists of the brain and the spinal cord. The spinal cord contexts the centre nervous system either the peripheral nervous system it acts at a path of information to travel
Brain
The brain is part of the central nervous ysen and receives stimuli from the world around us
Specialized cells in the muscular and skeletal system
Cardiac muscle cell- the muscle that works around the heart
Skeletal\muscle cell- muscle that works around the nervous system
Smooth muscle cells- located in the blood vessels and in hollow organs
Tissues in the muscular and skeletal system
Connective- supports and connects different parts of the body
Muscle- allows the body muscle to move
cardiac muscle to pump blood and intestine muscle to move food
The stuture in the sketial and muscular system and there function
Muscle- a band that contracts which allows movement of the body parts
-‘maintains of body postition and posture
Cartilage- connective tissue that provides support but is as risings as bone
-allows flexibility of movement
Tendons -highly organized connective tissue joining muscle to bone
Bones- structural frame works for reminds to attach to and provide support for soft tissue
Ligaments- the main type of ligament is tough and contexts one to to another bone
-provides joint stability
Joints- a place where two or more bones meet and responsible for movement
Organs in the respiratory system
Nose- prevents entry of dust particles air is brought into the body this way
Pharyn- prevents entry of food into the windpipe
Larynx- it produces sound as air passes through the hallow Kidd most call this the voice box
Trachea- to transport air a person breathes through his nose or mouth into the lungs
Bronchi- the main passage way into the kings
Diagotagm- the primary muscle used in the process of inhalation
About the lungs
The right lung is bigger then the left because the left has to hold the heart
Specialized cell in the respiratory system
The specialized cell in the respiratory system is called the alveoli they are hollow sac surrounding the capillaries
Tissues in the excretory system
Epithelial tissue- asking and the lining of the kidney
Muscle tissue- bladder contracts to release urine
The organs in the excretory system
Kidneys-filters water from blood
Bladder stores liquid waste
Ureters- carry waste from kidney to the bladder
Urethra- carry liquid waste of the body
Specialized structures in the circulatory system
Arteries carry oxygenated blood to the whole body
Veins carry deoxygenated blood back to the heart
Capillaries put oxygen in the muscles
Organs in the circulatory system
Lungs- oxygenated blood from the heart
Heart- pump blood to lungs then back to the heart then to the entire body
Arteries- carry oxygenated blood to the whole body
Veins- carry deoxygenated blood back to the heart
Capillaries- put oxygen in the muscles
Tissue in the circulatory system
The main tissue is the muscle the musicale tissue surrenders the heart and contracts pumping blood through your heart then to your entire body
Heart
The superior vina cava and the inferior Venna cava brings deoxygenated blood from the entire body into your right ventricle the blood is then pumped from the right ventricle and the right atrium into the pulmonary valve which is pumped into the pulmonary artery which pump to the lungs then through the pulmonary vein the ox need blood comes to the left ventricle
specialaized cells in the digustive system
The mircovilli is the specialized cell it forms finger like projections mircovilli line the inside of the small intestine
tissues in the digustive system
Muscle tissue surround the stomach. Perislasie in the esophagus is caused by contractions of muscle
tissues in the repiratory system
Diaphragm has muscles into inhale these muscles contract
specialized cells in the system excretory
Nephron are small capillaries. The kidney has millions of nephron. These microscope units remove wastes from the blood and produce urine
Which two body system work together during the process of gas exchange?
The respiratory system and the circulatory system
The respiratory system draws oxygen rick air into the lungs then the blood in the capillaries surrounding the alveoli and the blood inside the capillary is very short
What is the difference between an artery and a vein
Arteries carry blood away form the heart to all parts of your body
Vein blood returned from your body
What is the role of skin in your excretory system
The skin has thousands of tiny sweat glass just below the surface so it produces sweat to keep you cool
What is the difference between the somatic nervous system and the autonomic nervous system
Voluntary responses are controlled by the somatic nervous system
Autonomic nervous system are automatic responds
