Circulatory system

artery

A blood vessel that carries blood away from the heart

Which type of blood vessel usually carries oxygen-rich blood?

Arteries

What is the name of the valves that let blood flow from the atria to ventricles?

Atrioventricular valves

red blood cell

Blood cells that carry oxygen from the lungs to the body cells.

Why do you need blood?

Carries oxygen to body cells (red blood cells) Removes carbon dioxide waste(red blood cells) Helps to fight diseases, viruses and bacteria (white blood cells) Helps blood clotting (platelets)

atrium

Each of the two upper chambers of the heart that receives blood that comes into the heart

How can you tell where sugar enters the blood?

I can tell because the amount of sugar in the arteries entering the intestines and liver is less than the amount of sugar in the veins leaving the intestines. This means that the larger amount of sugar exciting than entering provides the evidence that sugar entered the blood in both the intestines and liver.

Where does the pulmonary vein carry blood from and to?

It carries blood from the lungs back to the left atrium

Where does the pulmonary artery carry blood from and to?

It carries blood from the right ventricle to the lungs

What are Valves

Keep blood from flowing backwards

Which chamber is located on the top right of the heart?

Left Atrium

Which chamber is located on the bottom right of the heart?

Left ventricle

Where does blood from the right ventricle go?

Lungs

How is the circulatory system similar to a road-and-highway system?

The major highways that run N, S, E & W allow vehicles to travel from place to place are like the large blood vessels like arteries and veins that allow blood to travel to all parts of the body. Blood is a tissue consisting of many cells and the vehicles on the highway are like WBCs, RBCs, platelets, water and other molecules and cells in the blood. In addition, capillaries are small vessels that are similar to side roads used primarily to allow residents to travel back & forth to their homes. The homes are like body cells and the sideroads are like the capillaries.

Why do the little balls change from red to blue and blue to red?

The red blood cells change from blue to red in the lungs because they release CO2 and pick up O2 thus becoming oxygenated. Red represents oxygenated blood. The red blood cells change from red to blue at the body cells because they release O2 and pick up CO2 thus becoming deoxygenated. Blue represents deoxygenated blood.

what do arteries do?

They carry blood away from the heart

What do capillaries do?

They carry blood to body cells

What do veins do?

They carry blood to the heart.

What substances does the excretory system create whose function is to get rid of waste?

Urine and Sweat

Which type of blood vessel usually carries oxygen-poor blood?

Veins

platelet

a small blood cell that helps the blood to clot

blood vessel

a tube in the body through which blood flows

urea

a waste product in the blood that comes from the breakdown of proteins.

Which vessels take blood away from the heart?

arteries

pulmonary artery

artery carrying oxygen-poor blood from the heart to the lungs

In which type of blood vessel is oxygen released into body cells?

capillaries

Where does sugar leave the body?

capillaries

What do red blood cells do?

carry oxygen

What is the purpose of the circulatory system?

carry oxygen and nutrients to tissues, carry carbon dioxide out of tissues, fight diseases and viruses

What do white blood cells do?

fight disease

How many chamber does the heart have?

four

What organ pushes blood through your body?

heart

What do the platelets do?

help stop bleeding when you are cut

Which system helps regulate body temperature and water loss?

integumentry

Where does sugar enter the body?

intestines

Where does urea leave the body?

kidney

Where does urea enter the body?

liver

Which organs are important parts of the immune system

lymph nodes, spleen, tonsils

What are the name of the cells used by the nervous system?

neurons

Enzymes, a group of molecules called proteins, are located in the ________________.

saliva

capillary

smallest blood vessel

heart valves

structures that open and close to control blood flow through the heart.

circulatory system

the body system that includes the heart, blood vessels, and blood.

What happens in the lungs?

the lungs add oxygen and remove carbon dioxide.

pulmonary vein

the vein that carries blood from the lungs to the left atrium

Where does blood from the left ventricle go?

through the body

Why is the left atrium and left ventricle shown on the right side of the diagram and the same for the right atrium and right ventricle?

The diagram is shown in anatomical position so the right and left are reversed.

Which Chamber is located on the top left of the heart?

Right Atrium

Which order does blood flow through your body?

Right Atrium, Right ventricle, Left atrium, Left ventricle

Which chamber is located on the bottom left of the heart?

Right ventricle

What are the names of the chambers?

Right ventricle, right atrium, left ventricle, left atrium

What is the name of the valves that allow blood to flow from the ventricles to the arteries?

Semilunar valves

How is the blood in the pulmonary arteries different from blood in other arteries?

The blood in the pulmonary arteries is deoxygenated and travels away from the heart to the lungs compared to all other arteries that also carry blood away from the heart, but the blood is oxygenated and brought to the body cells.

How is the blood in the pulmonary veins different from blood in other veins?

The blood in the pulmonary veins is oxygenated and travels away from the lungs to the heart compared to all other veins that also carry blood to the heart, but the blood is deoxygenated and brought back from the cells of the body.
