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
