Q

What does the Cardiovascular System transport

Study These Flashcards
A

-Nutrients from digested from food
-Oxygen from the lungs
-Metabolic wastes (Carbon dioxide)
-Hormones
-Heat

24
Q

4 Heart Chambers: Left side

Study These Flashcards
A

-Receives oxygen rich blood from the lungs

25
4 Heart Chambers: Right side
-Oxygen poor blood received from the body
26
Heart Beat: Upper chambers
-The ATRIUMS pump blood to the ventricles
27
Heart Beat: Lower Chambers
-The VENTRICLES pump blood to the lungs or throughout the body
28
What is the lub dup sound that doctors listen to?
Heart Valves -Lub: valves between atriums and ventricles -Dup: Valves between the ventricles and blood vessels closing
29
Blood Flow through the heart
1. Deoxygenated blood enters right atrium 2. Right atrium pumps blood to right ventricle 3. Right ventricle pumps blood to lungs 4. Oxygenated blood enters left atrium 5. Left atrium pumps blood to left ventricle 6. Left ventricle pumps oxygenated blood to body
30
Blood Pressure
-Arteries under pressure from beating heart
31
Systolic pressure
-Pressure from contraction of beating heart
32
Diastolic pressure
-Pressure at rest
33
EKG
- A machine that measures the electrical activity of the heart
34
Composition of blood
-Red blood cells -White blood cells -Platelets -Plasma
35
Functions of Blood
-Carry oxygen, nutrients, and hormones to the cells of the body -Pick up wastes and toxins from the cells -Fights infections
36
Red Blood Cells
-Red in color because of pigment called hemoglobin which carries oxygen from lungs to body cells -No nucleus -Carries oxygen -Produced in special tissue called bone marrow located inside certain long bones
37
White blood cells
-No color -Nucleus -FIghts infection
38
Plasma
-Straw colored -90% water -Transports blood cells, hormones, nutrients, cellular excretions, antibodies, salts, and proteins -Help regulate body temperature
39
Platelets
-Smaller than blood cells -No nucleus -Involved in clotting of the blood -Clog a cut, stopping bleeding
40
Blood Types
-A, B, AB, O -Types of blood determined by the presence of specific carbs on the red blood cells -AB are universal recipients -O are universal donors
41
Blood vessels (vascular tissue)
-Plumbing pipes of the circulatory system -Elastic tubes that accommodate pushing flow of blood
42
3 Types of blood vessels
1. Arteries 2. Veins 3. Capillaries
43
2 Major blood circuits
-Pulmonary circuit -Systemic circuit
44
Pulmonary circuit
-Short loop that carries deoxygenated blood from the heart to the lungs where it is oxygenated and returned to the heart (lung circuit)
45
Systemic circuit
-Carries oxygenated blood from the heart to the rest of the body and back to the heart, deoxygenated (body circuit)
46
Arteries
-Carry blood away from the heart to the body -Mostly carries oxygenated blood (except the pulmonary artery, which goes to the lungs with deoxygenated blood)
47
Example of an artery
Aorta
48
Capillaries
-Tiny, thin walled blood vessels -Gas exchanged across membranes of capillaries -Blood cells travel through capillaries in single file -Exchange of gases, nutrients, and wastes through diffusion
49
Atherosclerosis
-Arteries become narrowed -Cuts down flow of blood through the vessels -Rough surfaces on the artery lining can cause clots or stroke -Plaque in your arteries and capillaries
50
Stroke
Blocked off leaking artery in your brain
51
Veins
-Return mostly deoxygenated blood to the heart (except the pulmonary vein) -Veins have valves that help transport blood
52
Varicose veins
-Faulty valves in veins -Compression garments used to help
53
High Blood Pressure
-Blood Pressure in the arteries is increased -Damages the lining of the arteries and weakens the heart muscle
54
Lymphatic System
-Collects fluids leaked out of the capillaries and returns them to the blood -Returns fluid through a network of vessels and tiny bean shaped organs called lymph nodes -Plays an important role in fighting infection
55
Leukemia
-Form of cancer which causes bone marrow to produce too many white blood cells and crowds out red blood cells
56
Anemia
-WHen blood cells do not have enough hemoglobin or red blood cells -Body cells do not receive enough oxygen and develop low energy levels
57
What is the most common form of cardiovascular disease?
High Blood Pressure
