Heart Parts
This type of vessel always carries blood away from the heart
What are arteries?
This tube carries air from the throat to the lungs.
What is the trachea?
These cells carry oxygen using hemoglobin.
What are red blood cells?
This process moves oxygen from alveoli into capillaries.
What is diffusion?
This condition occurs when blood flow to part of the heart is blocked.
What is a heart attack?
The largest artery that receives blood from the left ventricle and sends it throughout the body.
What is the aorta?
These structures prevent the backflow of blood, keeping it moving in one direction.
What are valves?
These two tubes branch from the trachea into the lungs.
What are bronchi?
This component of blood fights infection.
What are white blood cells?
This process moves oxygen quickly through blood vessels.
What is bulk flow?
This condition occurs when blood flow to part of the brain is blocked.
What is a stroke?
Where blood goes after entering the vena cava.
What is the right atrium?
This structure brings deoxygenated blood from the body to the right atrium.
What is the vena cava?
This structure produces sound and is located in the throat.
What is the larynx?
This liquid part of blood transports nutrients and wastes.
What is plasma?
These tiny air sacs are where gas exchange occurs.
What are alveoli?
This disease involves abnormal white blood cells.
What is leukemia?
What valve blood passes through after leaving the right ventricle.
What is the pulmonary valve?
The only vein in the body that carries oxygenated blood.
What is the pulmonary vein?
This structure prevents food from entering the trachea.
What is the epiglottis?
These cell fragments help blood clot.
What are platelets?
This process releases energy from glucose.
What is cellular respiration?
This condition is when blood exerts too much force on vessel walls.
What is high blood pressure (hypertension)?
The blood travels in this vessels when returning to the heart from the lungs.
What is the pulmonary vein?
This vessel carries blood from the right ventricle to the lungs.
What is the pulmonary artery?
This "two-way highway" helps control breathing and heart rate.
What is the vagus nerve?
This protein in red blood cells binds oxygen.
What is hemoglobin?
This molecule is the main energy currency of the cell.
What is ATP?
This explains why high blood pressure is dangerous over time.
What is it damages blood vessels and organs?
Blood flows through this valve immediately after leaving the right atrium
What is the Tricuspid Valve?
This chamber is known as the strongest, largest, and main pump for the whole body.
What is the left ventricle?
Why alveoli have large surface area and thin walls.
What is to maximize gas exchange?
This is where red blood cells are produced in the body.
What is bone marrow?
The reactants and the products in cellular respiration.
What are:
Reactants: oxygen and glucose
Products: carbon dioxide and water
This is a key structural difference between red blood cells and most other cells.
What is they lack a nucleus?
The chamber where blood is before it moves across the mitral valve.
What is the left atrium?
