The components of blood
What is hemoglobin?
The hemoglobin is located in red blood cells, which grab oxygen from the lungs and transport it throughout the body.
Where does deoxygenated blood enter the heart?
The deoxygenated blood always enters the inferior vena cava.
What are the types of blood vessels?
Arteries, Veins, and Capillaries.
What are 2 systems in the Circulatory system?
The Lymphatic system and the Cardiovascular system.
What is blood pressure?
The force in which the ventricle of the heart contracts is what causes blood pressure.
What is a platelet?
This tiny cell fragment sticks together to form a ball or clot, preventing too much blood from leaking when you get hurt.
What happens after the blood is oxygenated?
It returns to the heart after entering the lungs and pumps through out the body.
What do arteries do?
Arteries have the job of carrying oxygen-rich blood.
What is the Lymphatic system?
It sends the white blood cells a message after detecting a virus in the blood.
What happens when you have high blood pressure?
High blood pressure is harmful because arteries or veins surrounding the heart can be cut off or broken allowing excess blood to flow all over the body.
What does plasma do?
Plasma is the goo-like substance that helps blood cells float and carries the nutrients an proteins that the body needs while also transporting it.
Where does deoxygenated blood go after entering the right atrium?
It pushes and contracts through the tricuspid valve.
What does a vein do?
Veins carry the blood to the heart (usually oxygen-poor blood but there are exceptions).
What is the cycle of the circulatory system?
When the blood pathway to the heart gets more smaller it will erode the blood pathway which increases blood pressure since more of the blood is giving more pressure.
What happens when you have low blood pressure?
Low blood pressure is harmful as well. If your body has low blood pressure, your body cannot get the nutrients or oxygen in the critical blood.
What is the white blood cells' job?
Their job is to fight bacteria and infections and they also have to be able to identify them.
What are the 4 chambers of the heart?
The right atrium and the right ventricle and the left atrium and the left ventricle.
What does a capillary do?
Capillaries are very tiny blood vessels that take waste
Does the circulatory system also remove waste?
Yes, it removes waste and brings nutrients throughout the body.
What is the regular blood pressure look like?
Regular blood pressure often depends on what you consume. Whenever you go to a place to check your bp then it has to be lower then 120 on the top bar and lower than 80 on the bottom bar. This means you have a steady blood pressure rate.
How do all the components of blood work together?
They all have specific jobs that are helpful for the body like the red blood cells carrying oxygen and carbon dioxide, Plasma in charge of blood movement, platelets to help heal, and white blood cells to prevent the body from infection. These all help our body in different ways but if we miss one component then all of them can not help the body survive.
Where does oxygenated blood go after entering the pulmonary vein?
The blood pushes itself to the left atrium and the cycle will repeat with both oxygenated and deoxygenated blood.
What is a valve and what is its job?
Valves are in charge of the blood flow through the body. There are 4 different types of valves which each has a specific way of pumping blood to different parts of the heart and body.
What is the difference between the cardiovascular system and the Lymphatic system?
The cardiovascular system is in charge of carrying blood and the Lymphatic system is in charge of the body's fluids, also known as Lymph.
Is blood pressure and pulse related, how?
The pulse of the heart is when the ventricle pumps blood through the heart and through out the body making sure that all parts of the body have blood circulating.
