What do arteries do?
Arteries carry blood away from the heart to an organ. Arteries are typically oxygen-rich.
What do veins do?
Veins carry blood away from the heart.
What is transported by blood?
Glucose/ gases are transported by the blood.
What does blood transport?
Blood transports nutrients, hormones, and gases.
What is plasma and what is in plasma?
- Plasma is the liquid part of the blood.
- Plasma contains water, proteins, and salts.
What three components is the blood made of?
- Plasma (liquid part: water, proteins, nutrients.)
- Cells (red blood cells, white blood cells.)
- Platelets - help your blood to clot.
What is the name of the iron-containing protein in red blood cells?
The iron-containing protein is called hemoglobin.
What are capillaries and what happens at the capillary level?
- Arteries branch into small blood vessels called capillaries.
- Where gas exchange takes place.
- Oxygen is delivered to cells/tissues.
- Carbon dioxide is picked up and taken to the lungs.
What blood does the right side pump?
The right side pumps deoxygenated blood.
What blood does the left side pump?
The left side pumps oxygenated blood.
Where does the deoxygenated blood enter the heart to become oxygenated?
Deoxygenated blood enters the superior or the inferior vena cava.
Describe the path of deoxygenated blood to the lungs.
Inferior vena cava - Right Atrium - Right Ventricle - Pulmonary Valve - Pulmonary Artery- lungs
Give a vein that carries oxygenated blood.
The pulmonary vein carries oxygenated blood from the lungs.
Give the artery that carries deoxygenated blood.
The pulmonary artery carries deoxygenated blood and takes it to the lungs where carbon dioxide can be removed and oxygen can be picked up.
After the blood has become oxygenated in the lungs, where does it go?
- Enters the pulmonary veins.
- Left atrium.
- Left ventricle.
- Aortic valve.
- Aorta.
What is the aorta and what is its function?
The aorta is the major artery that carries oxygenated blood throughout the body.
What is the pulmonary circuit?
The pulmonary circuit is between the heart and lungs.
What is the systemic circuit?
The systemic circuit is the circuit between the heart and the rest of the body.
What is the function and adaptation of arteries?
- Carry blood away from the heart (always oxygen-rich except the pulmonary artery.)
- Has thick muscular walls: withstands high pressure of blood.
- Thin Lumen so the blood can move quickly in a narrow space.
What is the function and adaptation of capillaries?
- Capillaries really close to cells to exchange substances.
- They have permeable walls.
- Only one cell thick increases diffusion by decreasing the distance that it occurs.
What is the function and adaptation of veins?
- Veins carry blood to the heart (always carry deoxygenated blood: except for the pulmonary vein.)
- Have thin walls.
- Larger passageways for blood (internal lumen.)
- Contain blood under low pressure.
- Have valves to prevent blood from flowing backwards.
What are blood vessels?
- Blood vessels circulate blood.
- Arteries carry blood away from the heart.
- Capillaries branch off from arteries and exchange oxygen and carbon dioxide.
- Veins carry blood to the heart.
What happens to the heart when we exercise?
- Heart rate increases.
- Heart pumps a greater volume of blood.
What colour would plasma be without the red pigment from hemoglobin?
Plasma would be straw-coloured without haemoglobin.
