Definitions
The blood vessels that carry blood back to the heart.
What are veins?
These blood cells contain hemoglobin.
What are red blood cells?
The blood clotting process is aided by these.
What are blood platelets?
When one exhales air, the air first passes through the trachea or the pharynx?
What is the trachea?
The tubes in plants that transport water up the plant.
What are xylem?
Of red blood cells, white blood cells, platelets, or plasma, this one makes up the majority of the blood.
What is plasma?
The vena cava dumps a sample of deoxygenated blood into the heart. Name each chamber of the heart through which the blood sample will pass in order.
What is blood flows into the right atrium, then is dumped into the right ventricle. After going to the lungs for oxygenation, it is dumped into the left atrium, then the left ventricle before being pumped into the body.
A man and a woman are singing. His sound is loud with a low pitch, while her sound is soft and higher-pitched. Which is passing more air over his or her vocal cords? And why?
What is the man because the amount of air passing over the vocal cords controls volume?
The blood vessels that carry blood away from the heart.
What are arteries?
In this process, blood seals wounds to keep it from leaking out an injured artery.
What is blood clotting?
These blood cells fight disease-causing organisms in the blood.
What are white blood cells?
A blood sample from a person's lungs is examined under a microscope. In the sample, the scientist sees little round sacs covered in capillaries. These structures are called what?
What are alveoli?
Tiny, thin-walled blood vessels that allow the exchange of gases and nutrients between the blood and cells and are located between arteries and veins.
What are capillaries?
A scientist examines a sample of living tissue under a microscope. As it passes through the vessels, the blood is oxygenated at first and then becoming deoxygenated as it passes through the vessels. The type of blood vessels the scientist is examining are arteries, veins, or capillaries?
What are capillaries?
Deoxygenated blood leaves this chamber of the heart on its way to the lungs.
What is the right ventricle?
A sample of blood is oxygenated. Did it most likely come from an artery or a vein, and can you be 100% certain?
What is the blood most likely came from an artery because most arteries contain oxygenated blood? Because exceptions exist, one cannot be certain.
This is what produces blood cells.
What is bone marrow?
