Anatomy Flashcards
the 2 types of fluid moved through the card vas system
blood
lymph
what are the 2 parts of the cardiovascular system
cirulartory system
lymphatic system
3 major parts of the circulatory system
- Heart
- Blood
- Vessels
3 types of vessels
- Artery
- Vein
- Capillarys
What do Red Blood Cells do?
- cary oxygen to cells of the body
- picks up carbon dioxide through hemoglobin
What do white blood cells do?
Immune system
Fighter Cells
What does Platlets do?
clots our blood
what is plasma in the blood?
Water in the blood
what does the heart do ?
forces blood to the body
3 layer of the heart ?
pericardium ( outer protective layer )
myocardium ( muscle of the heart )
endocardium( inner protective layer / membrane )
what is a heart murmer?
one of seals is not fully sealing
signs of right sided heart failure
Edema (swelling)
signs of left sided heart failure
shortness of breath
2 types of blood pressure
active / systolic
resting/ diastolic
the major organ in the lymphatic system
spleen
then liver
what does the lymphatic system run parallel 2 ?
the circulatory system
what does the lyphatic system do ?
keeps body fluids in check
and its a filtering system
what is the lymphatic system made up of ?
organs
lymph nodes
lymph ducts
lymph vessels
what is lymph ?
A watery fluid that contains , protein, salt ,urea glucose
what % air is O2?
21%
what does an artery do ?
takes blood away from the heart
what do your veins do ?
carry blood towards the heart
what does a capillary do ?
prefuse/ bring blood surface of the skin
what does the lymphatic system do ?
the filter system of the body ( could carry infection throughout body )
its also the first line of defence, lymphocytes sense infection and starts the production of white blood cells
what does the respiratory systems main purpose
transporting air
breathing in - brings in O2
breathing out - lets out CO2
upper parts of the respiratory system ?
nose nasal cavity mouth pharnx larynx ( voice box) trechea bronchial tube
lower section of respiratory system ?
bronchi (oli)
alveoli
lungs
Diaphragm
how many lobe on either side of the lungs?
left has 2
right has 3
normal rates for adults and infants ?
pulse (adult ) 60- 100 (infant) 150 blood pressure (adult)120/ 80 temperature 36.8 respiratory (adult) 12/20 (infant) 30/39 oxygenation 92% 100% pain 1/10 infants
process of the heart / beat
blood comes in through the venacava veins both superior and inferior into the right atrium / down through the tricuspid valve and into the right ventricle / this blood is then pushed through the pulmonic valve into the pulmonary artery to the lungs for oxygen / once it has O2 it returns through the pulmonary veins into the left atrium through the mitral valve into the left ventricle/ blood is then pushed through the aortic valve into the aorta to be distributed to the body
why do we have valves in our heart
to keep blood flowing one way
the muscle in the respiratory system ?
the diaphram
what is the same of the protective sac around the lungs called?
the plural sac
the divider in the centre of the heart
septum
common places to feel lymph nodes?
Groin Armpit Neck (there is a chain of lymph nodes on either side of the front of the neck, both sides of the neck, and down each side of the back of the neck) Under the jaw and chin Behind the ears On the back of the head
