4 components of the cardio sysyem
|
Blood Heart vessels lymphatics
|
|
Cardio system/ Blood
|
carries oxygen, lymph, hormones,nutrients, diseases,water,CFS,Ki, protiens
|
|
cardio system/ heart
|
muscular pump, pumps 60 to 80 per min
|
|
cardio system/ vessels Three types
|
Arteries- take blood away veins- take blood to the heart. capularies- changes take place hear. diffusion takes place.
|
|
Cardio system/ lymphatics
|
carries waste. carries 1 liter of lymph flows thru body
|
|
Blood
|
8% of body weight. is connective tissue. because cells are in your plasma matrix
|
|
Extracellular matrix
|
plasama is 92% of water. Electrolytes are 5% plasma proteins are 3%
|
|
Electrolytes
|
are ionic substances, such as sodium, potassium, calcium.
|
|
plasma proteins
|
3 catergories of proteins
|
|
albumins
|
play specific roles in transporting substances in the blood
|
|
Alpha and beta globulins
|
function as transport molecules and clotting factors.
|
|
gamma globulins
|
are the antibodies of the body defense system
|
|
Cells Erythrocytes(red blood cells)
|
only cell without nucleus, carry oxygen.99% of all blood cells.
|
|
Trombocyte(platelets)
|
small enucleate cells forming flattened biconvex discs.roundish, blood clotting.
|
|
Leukocyte( white blood cells 55 types
|
leukocytes are involved in body depense and repair.
|
|
#1 Component-Blood
|
is connective tissue. Cells float in a fluid extracellular matrix
|
|
blood cells-Eyrthrocytes
|
red blood cells. They carry oxygen throughtout our body
|
|
blood cells-Thrombocytes
|
platelets- assist in forming clots and scabs
|
|
blood cells-Leukocytes
|
white blood cells-these cells wander throughout the bloodstream to support our immune system
|
|
#2 component-Heart-topography
|
the sternum is anterior, the aorta and esophagus lie posterior, the lungs are lateral,the trachea is superior and diaphragm lies inferior
|
|
Largest veins of the body
|
Superior and inferior Vena Cavas. Carry deoxygenated blood into the Right Atrium of the heart
|
|
Next, this blood travels
|
thru the Tricuspid valve into the Right Ventricle
|
|
Next,this blood travels
|
thru Pulmonary valve into the Pulmonary Arteries
|
|
Blood travels to lungs
|
to recive a new supply of Oxygen
|
|
Oxygenated blood next travels
|
back to the heart via Pulmanary Veins
|
|
Next the blood enters
|
the Left Atrium
|
|
Next this blood travels
|
thru the Mitral Valve into the Left Ventricle
|
|
From thick walled Left Ventricle
|
pumps blood thru the Aortic Valve into the largest artery of the body called the Aorta
|
|
From Aorta
|
blood travels away from the heart towards the tissues in the body
|
|
#3 Component- vessels
|
Arteries Veins Capillaries
|
|
Arteries
|
carry blood away from the Heart. The Aorta is the largest artery of the Body
|
|
Veins
|
carry blood towards the heart.viens have valves to support proper blood flow.Superior and inferior vena cavas are the lagest veins of the body.
|
|
Capillaries- exchange vessels
|
oxygen and waste are exchanged between capillaries and individual cells
|
|
Three layers of blood vessel tissue
|
Tunica Intima Tunica media Tunica externa
|
|
Tunica Intima
|
simple squamous epithileum that lines the entire cardiovascular system. Capillaries only have this layer.
|
|
Tunica Media
|
smooth muscle and elastic tissue are found here to regulate blood flow.Arteries and veins have this layer
|
|
Tunica Externa
|
dense irregular connective tissue layer providing strength and protection. Arteries and veins have this layer, however its usually thicker in arteries
|
