Dayani Solano Per.2 Cardiovascular System
Major components and functions of Blood
platelets
helps blood clogging
white blood cells
part of the immune system
help fight infection and diseases
red blood cells
carries oxygen from the lungs to all parts of the body.
plasma
take nutrients, hormones, and proteins to the parts of the body that need it
carries water, salts and enzymes
Major functions of the cardiovascular system
Provides cells with NUTRIENTS.
Removes the waste products of metabolism to the excretory organs for disposal.
Circulates OXYGEN and removes Carbon Dioxide.
Protects the body against disease and infection.
Clotting stops bleeding after injury.
Layers of the heart
myocardium
Muscle layer
~middle layer
Comprised of cardiomyocytes
endocardium
Lines inner surface of heart chambers and valves
layer of endothelial cells, and a layer of subendocardial connective tissue
epicardium
Comprised of mesothelial cells and fat and connective tissues
Visceral layer of serous pericardium
ABO, Rh blood types
ABO consists of A, B, AB, and O
Rh blood types is either positive or negative
Blood flow through the heart and body
step 2: right atrium
step 3: tricuspid valve
step 1: Inferior vena cava
step 4: right ventricle
step 5: pulmonary valve
step 6: pulmonary artery
step 7: lungs
Anatomy of the heart
Left ventricle
pumping oxygenated blood to tissues all over the body.
pulmonary valve
lies between the lower right ventricle
Left atrium
receives oxygenated blood from the lungs and pumps it down to left ventricle, delivers it to the body.
Right ventricle
pumps blood low in oxygen to the lungs
tricuspid valve
let blood flow from the right atrium to the right ventricle.
Right atrium
pumps this deoxygenated blood into the pulmonary arteries around the lungs
aortic valve
opens when the left ventricle squeezes to pump out blood, closes in between heart beats
keeps blood from going backward into the heart.
mitral valve
lets blood move forward through the heart during half of the heartbeat.
Cardiac cycle and the ECG
2) Inflow
1) "Isovolumic relaxation
3) "Isovolumic contraction"
4) "Ejection".
Major blood vessels
veins
pulmonary, systemic, superficial, and deep veins.
arteries
ascending aorta, aortic arch, thoracic aorta, and abdominal aorta.
Structural and functional differences between blood vessel types
veins
return deoxygenated blood from your organs back to your heart
capillaries
are where oxygen and nutrients are exchanged for carbon dioxide and waste.
arteries
the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body
Vital signs
respiration
normal: 12 to 18 breaths per minute
pulse
normal:60 to 100 beats per minute
pupils
normal: dilating by light
blood pressure
90/60 mmHg to 120/80 mmHg
Disorders of the cardiovascular system
peripheral artery disease
symptoms
:leg and arm pain, weak pulse, hair loss
causes
:limb trauma,smoking,obesity
description
:arteries narrow and reduce blood flow to extremities
stroke
description:
blood flow to a portion of the brain is interrupted
symptoms:
confusion,memory loss,muscle weakness
causes
:blood clot in artery to the brain,age/race,diabetes
heart attack
causes
:blood clot, high blood pressure,plague in coronary arteries
symptoms
:chest pain, sweating, dizziness
description:
blood flow to part of the heart that is blocked
endocarditis and myocardities
description:
inflammation of the heart
symptoms
:chest pain,fever,edma
causes
:virus,bacterial infection,recent surgery
congenital heart disease
description:
issue w/ heart structure and function present from birth
causes
:aortic stenosis,tricuspid atresia
symptoms
:dependent on condition,cyanosis common,asymptomic
